This will help with diets
Exactly what they were used for as always been a bit odd. But the best hypothesis is that they kinda work like sauropod necks. IE it allows them to react and feed over a much wider immediate area. They are more agile in that sense.
So more like pot kai, less like bob elasmo
BoB elasmo is kind of the general idea but it's overexaggerated to the point of being basically on crack
Less twisty?
yeah
I’m assuming also less at the speed of a bullet lol
you can see the range of motion here
That's pretty good then
And on the diet of kai, is the filter feeding just one fringe theory or is that the more common theory?
It straight up was a filter feeder. Aristonectine elasmosaurs in general developed that feeding strategy. Kaiwhekea is more basal in the group, so it probably wasn't as developed as in mortuneria and aristonectes, but it probably still did it. Keep in mind I'm talking about substrate filter feeding, akin to gray whales, not surface filter feeding like other baleen whales, basking and whale sharks, and everybody else we associate with filter feeding.
Sand sifting basically. Did it have the capability to still munch fish and have that biteforce or did it sacrefice all that for muh sand munchies?
who knows
Guess the kais do. Thanks for the info 
maybe in the future in game we'll getting some yummy looking patches of sand
I read ur username for a sec and thought it was vivdskii, pronounced like that
it was named after a country in africa
i repeat, it was named after a country in africa
I'll say it in each one, but I feel like you don't need to put a "disclaimer" that it's a country in Africa
Anyone with half a non-racist braincell knows that
Yeah idk why that needed to be said either
Does anyone have a good reference for the skull of sinosauropteryx? Specifically looking for one that has been reconstructed to account for the deformation of the fossilization process.
Reason is I’m considering getting a tattoo of its skull and I want to get other folks’ opinions on which is most up to date
There are plenty of images online, but they are usually still in the rock matrix or are are depicting the tissue surrounding the bones, as well as ones that are overly simplified
I'd use hartmans sinosauropteryx skull maybe?
Considering Leedsicthys is one of the expected playables, we might have something similar to this in the sense of a ball of krill or plankton.
Really not sure why they wanted Leedsicthys though.
largest bony fish plus its effectively a whale for things to hunt without being cenozoic
Yet large Sauropods were a no go?
Giant fish are in the water where there aren't concerns of managing it with varying elevations and navigating the foliage
maybe they should’ve just made better maps
There's probably other reasons, also considering leedsichthys is big but not THAT big. Its within the limit.
But this is paleo chat not pot chat
Cool comparison ( credit to @tough parcel )
"Utahraptor." Nobody bats an eye.
"Nigersaurus." Everyone screams.
Went to a computer club a few years ago and some black kids looked it up and was like hey its the REDACTED saurus!
Like, just a name of a country. It's like naming a dinosaur "Chadotitan."
Correction, deinosuchus is an alligatoroid. Might not seem like a major difference but deinosuchus’s lineage split off before proper gators and caimans did, which means it’s not really an alligator or caiman in the sense that we understand.
Tbh, I don't really love deinosuchus that much, like it's really cool IG but it's not a favorite of mine, although I still main it in TI (idk why it's tail is so skinny in that game, but other than that great design) but yeah, deino is cool just not my favorite
Yeah I wanted to use this but zooming in on the skull doesn’t give high enough resolution
I’ve always thought it’d be funny if someone used giga in the generic name of something and gave it the specific name chadensis
Of course I don’t know how good of a region Chad is for fossil hunting
Actually Deinosuchus and Alligators and Crocodiles would have been alive at the same time. Since Gators and Crocs have been around for at least 150 million years.
Crocodilians proper first appeared 95 million years ago or so. Everything before that is various relatives that aren’t actually crocodilians. It’s like how everybody goes on about sharks being around for 400 million years when that isn’t even true. Sharks first appeared during the Jurassic. Everything before that was wierd relatives that just kinda look like um.
if i remember correctly true crocodilians didnt appear till roughly around the KPG extinction event
everything before that was a crocodylomorph but not a proper crocodile
Deinosuchus is a proper crocodilian, specifically an alligatoroid, but it’s lineage split off before alligators and caiman did, so it’s kinda neither while still being related to them.
and Sarco is a Pholidosuchian so not a proper
Ye
still we say croc cause of convience
It's still a crocodyliform and a crocodylomorph so it still has croc in a couple of it's classifications so saying it's a croc isn't technically incorrect (it might only be a crocodylomorph or only a crocodyliform, Im not too sure)
I know.. sarcos a Pholidosuchian but it looks enough like a proper croc to simply be refered to as one for convenience cause try explaining crocodylomorpha and true crocodilians to laymen and try not getting a headache
Sarcosuchus is a cool fella (there was something wrong with that image when I posted it last time)
shame is didnt coexist with spino..but thats north africa for ya
It did coexist with sucho though
sucho the poor mans spino that was too fat to swim
I mean, depending on who you ask spino wouldn't have been all too great of a swimmer either
You say that when it’s was the apex predator in its ecosystem. Like, sarco’s it’s only competition and sucho’s still significantly larger.
being a great swimmer and being able to swim are to different things...i personally suggest it could punt like a hippo
Paraentelodon is cool
counterpoint deodon
Paraentelodon is significantly larger than daeodon and based on its tooth enamel it might have been more omnivorous/herbivorous than other entelodonts afaik
it wasnt as cool with Astogorgosuchus it coexisted with
Astorgosuchus is the best fr fr
shame its...not terrible material but its not much
Paraentelodon is cooler, can't change my mind 
(I still think puru and sarco are cooler than astorgosuchus)
giant crocodile that could hunt Paraceratherium..smaller ones
Giant crocodile that would hunt dinosaurs is cooler (talking about sarcosuchus specifically)
literally any decent sized crocodylomorph in the mesozoic
Comparison between 2 different estimates of sarcosuchus
S. hartii was smaller most likely
Yea, S. hartti is not in this image though
Hartti is the grey one
i just like the fact SA and Africa for a long time have the whole Morrison/Lourhina fauna thing with Oxalaia and Spino and here just a second Sarco species
It's still 5.5 meters though lol
This is a 5.5 Meter crocodile so S. Hartti was about as big as this guy
RIP Lolong
This is Cassius, lolong was 6.1 meters
meant to reply to this, it was abrasive food, possibly iirc plants with high fiber content that paraentelodon likely ate
its a entelodont...more then likley wouldnt turn down free meat
this is vegetation we're talking about not meat, but ofc it would eat meat
i know
sad lolong died on my birthday
Lmao so sarco basically never went extinct
SO WHO TF IS THE BIGGEST???
Deino

Is there a new thing about an upsize for another croc or something and it's just not publicly available yet?
No, it's just people have called Fadeno's Deinosuchus size into question and Purussaurus' former estimates as well, so we might (if anyone takes another look at them) see a size change
I do question fandenos deinosuchus but it still seems to be the largest (older estimates of his put it at 12-13 meters and 8-10 tonnes which is much more reasonable)
rhamposuchus the forgotten giant
disappointing.. ik that planet dinosaur is out of date or smt but sarco looked quite large compared to charcar
IIRC the Sarco with Spino and Carchar in PD was meant to be an undescribed pholidosaur, but I forget where my source is for that so take it with a pinch of salt
Sarco got hit with a hard downsize, ot went from 11.65 meters and 8+ tonnes to 9-9.5 meters and 4.3 tonnes
I think it's just based on the older sarco estimates but I could be wrong, ironically sarco is one of the better designs of the show
hard to screw up sarco to be honest
oh my FJUIQEHGIQEKQJEGKJQHIEJGKJQEGQEGHHQEING god bruv
Path of titans sarco:
Now is the material Fadeno based his shtuff on still representing the largest specimens?
It was a fun project + a great opportunity to bring my PhD research to the screen. Fun fact: Sarcosuchus (which did not live alongside Spinosaurus) was included as a stand-in for unnamed large KK pholidosaur. Similar story for Ouranosaurus (stand-in for mysterious KK ornithopod).
I'm still so sad that I accidentally encouraged random to downsize his sarcosuchus estimates lmfao
Probably, but it's hard to corroberate his stuff...someone should force random at gunpoint to look at it 
It does when your whole thing is being "the super croc"
I don’t think that’s what Sarcosuchus means
flesh croc
I should not have asked about the estimates you get for sarcosuchus based on terminonaris 💀 (it was indeed a mistake)
Is any croc not a flesh croc💀
unless we get a bone croc
I hope this man gets described soon
Ha ha ha (it's been over 10 years)
Never getting described, cope
In the end it's just another single partial bone
Do we know anything about it other than "big"
Perhaps, but I don't

paraenteldon sweep
the jaw muscles in entelodonts are amazing
Where’s the 4.3 ton sarco estimate from? Haven’t heard that before.
upper estimate from this https://academic.oup.com/iob/article/1/1/obz006/5418825?login=false
I think someone else got similar results from some other method
Hello
Someone made a skeletal using daeodons body with paraentelodon "proportions" so we got a paraentelodon skeletal It seems?
A paraceratherium? You mean paraentelodon?
Yeah paraentelodon, now we need somone to scale this with lambs and metasuchus's astorgo
Strong hippo vibes ngl
They are related iirc
Well then hippo vibes check out
Hi scanova
Wait, so uh, how heavy did you think it was?
3.5 from random
Same paper, just the lower estimate, also this
Fair
so... sarco is 9.5-10.13 meters long & 3.5-4.3 tons?
No, it's 8.9-9.5 meters and 3.5-4.3 tonnes, the 10.13 meter, 5.4 tonne estimate is based on living Croc, based on terminonaris (a close relative) you get 8.9 meters
@stiff osprey did I get that right or am I being stupid?
yeah that's right
Tbh I don't really think the 10.13 meter estimate is bad but I don't think the 8.9-9.5 meter estimate is more likely but 10.13 meters isn't impossible
For this reason I usually say 9-10 meters
is sarco was a smth called "Crocodyliform" or a smth called "Pholidosaur"? (yes ik sarco wasn't even a crocodilian)
I think pholidosaurs are crocodyliforms so sarco is both.
I will never understand how some people can see this bundle of rocks and go " oh yeah that's a dinosaur"
It's a juvenile parasaurolophus btw
Look harder.
It literally looks like burned wood
Yeah if nobody told me it was a dinosaur I probably wouldn’t have realised it
How do paleontologists even make money? Who pays them?
University probably
Paleontology is not a lucrative field, and a lot of people in the field work 2nd (more stable) jobs
Weight of triceratops and stegosaurus 2023 specimens?
behold
not-a-croc
7.8 metres 7-8 tonnes for Stegosaurus, and I only know CMM 8862’s estimated total length, 9.7 metres.
if you do it right it absolutely can be a lucrative field, university faculty positions are the most common and they can make a good amount of money at least in the US
I’m not just spouting that either I know paleontologists personally that live comfortably from faculty positions, those that work for oil companies are even better off
Define "if you do it right"
If you were experienced enough it would stand out immediately as bone, but it definitely takes a bit to get used to it.
if you know how to get a job and don’t just leap into the field blind
it’s like anything else, you need to be able to find a job and understand what you’re looking for, if you can do that you’re in good shape
In canada they make around 65k-130k per year afaik
What dinosaurs are usually found in ethiopia, I know there is some acrocanthosaurus teeth in ethiopia assigned to acrocanthosaurus sp. but what else
I'm going too guess these are going to mostly be x dinosaur sp. 
it’s mostly tooth taxa yeah, an unidentified theropod, a small ornithopod, a dromaeosaurid (maybe), and a brachiosaurid all known from teeth
Gotta love tooth taxa
what requirements for path of titans for computer ?
#help #path-of-titans would be best too ask
oh thanks ❤️
You guys have still yet to prove Giganotosaurus had the intelligence in order to hunt sauropods
Well this is an interesting conversation
And this image is one I'm going to be referencing
We can’t, neither can you. Having unremarkable intelligence is not a really a major factor my presumptuous peer
Again its already hard to understand how smart modern animals are let alone extinct ones
Yes it is, No reptilian pack hunts the way you guys are saying it, And may I mind you they are much more advanced then there archosaur cousins
Do you have an alternative prey selection for large bodied Carcharodontosaurids?
For sure
I do, i'll explain it after slow chat
Alright we’re getting somewhere I think
Reminder that hyenas can problem solve and are on the same tier as a chimpanzee intelligence wise but nobody really talks about it.
While yes, you guys could refer to the OTHER SAUROPODS, they are much to small to refer to the large ones we are talking about.
So, they hunt Sauropods
I should have been more specific in the Sauropods im refering to, They wouldn't be able to hunt the much large ones
candeleros monster 
Going back to the previous image, the one shown before
Why not? They were perfectly designed to do so
Because biting it's butt isn't going to get it the meat in needs to survive
Why not
caudeformalis would be a nice spot actually (ignore my spelling)
Disables major locomotion, it’s immobilised. What’s to stop these big bois from becoming a snack
I'm going to explain to you the amount of tearing the Giganotosaurus would need to do to the Sauropod for it to flesh graze meat, which wouldn't count as flesh grazing anymore
Who says that it has to be from a single sauropod
Archosaurs are a group of reptiles that includes dinosaurs, also fun fact, birds are reptiles and those guys are pretty intelligent, no I do agree with you that they wouldn't hunt massive healthy adult sauropods but you saying reptiles are not super intelligent isn't correct, Crocs have been known to use sticks to lure birds closer to them so they can attack iirc
Again it's not going to disable locomotion if it can't use it's bite to slice effective places on the sauropod, It can't go for the leg nor can it go from the sides
Hello, how can I change my referral code? I used wrong one instead of friends :/ thanks for the help!
Why not
While crocdilians which I do agree are very intelligent and so are birds, you have to understand that Archosaurus as a whole were composed of many other species of dinosaur, Birds aren't going to have the same intelligence as a Giganotosaurus because of how distantly related they are
idk if this will settle the argument but it didn’t need to hunt adult megasauropods all the time and it probably didn’t, there would be plenty of much easier to hunt smaller juvenile sauropods around, how smart it was really doesn’t have much to do with it
Hunting is nuanced imagine that
As I said before using the model provided, The giganotosaurus has no effective way of taking down large Sauropods, It's not going to be able to bleed it out due to how much blood sauropods are able to pump. Yet people still refuse to accept that.
We have animals such as komodo dragons with a similar tooth morph and a comparable size in the prey they hunt, Water buffalo
the caudofemoralis is a decent spot to bite if you can actually reach it, which wouldn’t be an easy feat when there’s legs kicking and a tail swinging at you
Besides how can we accurately measure how intelligent. Yes we can model it’s brain size using the brain case, but since it’s not alive we cannot accurately measure it’s intelligence.
And that's the problem, how much meat could be ripepd off for it to considered a viable hunting method
We can barely accurately measure the intelligence of stuff alive today
It also depends how we classify intelligence
it was just said that they wouldn’t have gone for adult massive sauropods most of the time unless there are no other options
Bum eating.
Apparently young, sick, old or injured sauropod just didn’t exist ig.
I’m pretty sure there’s a greater weight disparity between Komodo Dragons and Water Buffalo
Most komodos weigh around 150lbs or so, largest was 366lbs. Water Buffalo weigh between 1500 and 2645 lbs
I don’t know why they’re using a single giga against a healthy sauropod as an example of what would commonly occur, because it’s likely that that wouldn’t have happened much if at all. Predators don’t risk their own health unless in severe stress with no other choice, and no way in hell would a lone giga risk death if it could just hunt smaller prey
No, although it is believed carcharadontosaurids had a similar level of intelligence to carcharadontosaurids although we can't fully be sure of that, still not saying they hunted massive 50 tonne sauropods but calling them unintelligent isn't really accurate
I entered in 200lbs to 2200lbs and got a 1:11 ratio
Which means they’re hunting something that can be like 10 times it’s size, or even more.
Giganotosaurus coexisted with plenty of more reasonable sauropods. Not every sauropod in a given region was an Argentinosaurus. This also isn’t even considering how sauropods were r-selected and likely had way more immature animals in a given region than proper adults.
giga didn't even live with argent
Hunting water buffalo isn't exactly a common thing
Also while Komodo dragons do hunt buffalo, it is a rare occurrence and even rarer still to succeed.
And 8 tonne theropod and an 80 ton sauropod has an 1:10 ratio, not to mention that giganotosaurus likely exceeded this size, and the largest sauropods have estimates which range a bit lower than this
Nothing that lived with giga was an Argentinosaurus............
yeah not being able to be hunted as adults was kind of their whole thing, if you’re safe as a healthy adult it means you can pop out a lot more babies
I meant as in, yknow, 30 meters and over 50 tons. I know the two don’t coexist so relax lol
Although it seems Giga didn't really hunt rebacchisaurs a lot 
Young Sauropod: I can't wait to be a giant adult!
The local Giganotosaurus that hasn't eaten for weeks:
The youngins and maybe even the sub adults of those larger guys would do just fine
Even adult sauropods having predators isn’t really a revolutionary concept, but at the same time the “megasauropods” were probably outright immune to predation as healthy adults. I doubt even a group of mapusaurus is tackling a healthy adult Argentinosaurus.
Suggesting that they can’t hunt any of these Sauropods was the first mistake in the argument.
There’s just a certain point where you’re way too thick to be worth it. Even discounting the risk of injury it would likely be way too much energy to be worth it.
Shoutout to a subadult blue whale taking 5 hours to die from 50 orcas
what
It happened off Australia a few years back. A mega pod of 50 orcas took out a subadult blue whale. It took them 5 hours to do it.
Bonkers.
Rb for megapacking smh
Kos orca megapack at au
Based blue whale
Fewer orcas have taken down young blue whales in way shorter amounts of time, so I think that was just a skill issue on the orca's part
Or they were dealing with the most pro blue whale player that ever lived
Top 1% blue whale player
chad astorgosuchus enjoyer vs sigma paraentelodon enjoyer 
Yeah I’m reading similar occurrences and they usually don’t take as long.
Reptiles > mammals, specifically Crocs, Crocs are just so good at everything they do
Running Speed: 
I mean the terrestrial varieties exist
The so called age of mammals when the largest terrestrial predator is a croc:
How much does barinasuchus weigh?
1,700 KG
Paraentelodon when it weighs the same (sorta)
I think it’s called the age of mammals because they rapidly diversified
Well technically some estimates for barinosuchus put it even higher but those aren't exactly credible
same with paraentelodon you can get up too 2000kg via tooth scaling
Also if crocs are so good then why is Crocodilia the only surviving clade? 💅
eocene mass extinction go brr
🐊🔛🔝
I mean, didn't you just answered it by yourself

say what you will but the group can take hits like nobody’s business
Crocs during the kt extinction: “Tis but a scratch”
Alright
I don't want to argue about giganotosaurus being able to hunt Adult Sauropods, I'd rather chill with some paleo nerds and just talk about dinosaurs, Sorry for the trouble
So, does anyone have an opinion on why Tyrannosaurs are carried by Tyrannosaurs Rex?
I mean every other Tyrannosaurid, Albertosaurus, Gorgosaurus, Tarbosaurus, and of course, lythronax don't reach the same size of Tyrannosaurs Rex. Comparing that to other much larger theropods such As giganotosaurus The tyrannosaur family is really small
Wdym?
The tyrannosaur family is so small when it comes to large specimens
Rex is an extremity
But even so, Carcharodontosaurids aren't all that huge either. Conca is a good example
But to be fair, The Carchardontosaurids have much going for them in size compared to the Tyrannosarids
Rex is just the most well known and unique of the Tyrannosaurids. There are anatomical features exclusive to the genus not found in other Tyrannosaurids such as the wide skull.
Tarbosaurus co-existed with large sauropods and had adaptions more similar to that of a Carchardontosaur instead of a tyrannosaur
If no one wants to answer that question, anyone know what Spinosaurus was adapted for besides fish? As of right now it's very slow, and could barely hold itself up, But considering how large the fauna was during that time, Such as the plenty amount of carnivores running around, isn't it fairly strangle that Spinosaurus, Possibly the largest spinosaur, simply be adapted to fish, when it's cousin such a baryonx were more land adapted
Zhuchengtyrannus and the Udurchukan Formation has big Tyrannosaur remains
They pale in comparison to other large Mega Theropods, Which is why Tyrannosaurs rex is considered one of the only Mega Theropods in it's family, as tarbosaurus and Zhchengtyrannus are in the 5 ton range
5 tonnes sounds pretty big to me 🥱
Not as big as say 10 tons, or 9 tons, nor 8 tons, Which is what all mega theropods are ranked by, above 5 ton range, Which isn't small but isn't comparable considering how big they could have gotten
I heard above 3 tonnes is the megatheropod category
Because it's the largest terrestrial carnivore ever (possibly, giga may have been larger)
It's not, then yutyrannus would be considered a mega theropod, which is not
There's also probably a lot of tyrannosaurids more closely related to rex that we don't yet know about that are large
Yuty isnt 3t tho
Well that's the problem, Tyrannosaurs are known from semi large creatures, Nothing large. If we compare that to Giganotosaurus and it's family, you can see a clear difference. They had much large builds and it had been very consistent.
Megalosauroidae getting forgotten when it comes to big theropods 
I think you're looking too much at Carcharodontosaurines as if they're the entire family.
What about spinosaurs? They are large as well
Spinosaurs are consistently the largest predators in their ecosystems, without fail.
See?
Gonna blow your mind but that's how it was for tyrannosaurs too
I suppose you could say depending on your estimates, spinosaurus was an exception, but other than that afaik Scan is right
I wouldn’t call tyrannosaurs small though. Tyrannosaurus is just so exceptionally large it doesn’t do the rest any favors. They’re still cool in other ways though, such as the fact that tyrannosauroids are the predatory theropod group with the most evidence of sociality.
Considering the fact that Tyrannosaurus were always small when other larger predators were in the ecosystem, or were semi large when it came to them taking over, I really don't see how they went from decent, to having an extremely advanced indivaul which rivals all other mega theropods
Do you have anymore, it is incredibly pleasant to look at
I bet there’s a big Central American Tyrannosaur we didn’t find
To the point where the dynamics of said social groups might’ve been a good reason why their arms got so small.
I have this by falcon, the spinosaur one is by dino dan, and above that idk
What ecosystems did tyrannosaurs inhabit where they weren't the largest terrestrial predators
The problem is that other tyrannosaurids either were medium sized theropods, or barely capped large. T.Rex is the only one in the family which decide to become large
Wait what’s the discussion here exactly.
Why do tyrannosaurs get carried by tyrannosaurs rex alone when it comes to adpatations,Size,Intelligence
there's a very basal Tyrannosauroid from Uzbekistan that lived along side a carcharodontosaur larger than it
Because.
Timerlungia or smth iirc
Tyrannosaurid I mean.
I would contend a 5 ton tarbosaurus and a 3 ton Daspletosaurus are quite large.
Alright them me grab a diagram for example
- preservation bias
- Zhuechengtyrannus and Tarbosaurus
- your definition of medium size here given the context is very flawed
Pretty sure said carchar is dubious now tho cause the remains were garbage
shame
It’s a traditionally cursorial lineage, Tyrannosauroidae broadly at least. That might play a part. Or simply you could say they are as big as they need to be
Look at this absolute unit
Carcharadontosaurus was larger than spinosaurus
There would’ve been less of a reason to get to said rediculous sizes if they were social animals. There’s a point where your numbers outweigh the need for large body sizes. If everyone in your group is a unit that just means uneccesary higher food intake. Although, again, they’re still very large animals and T. rex just inflates it and makes the rest look smaller
Compare that to any other tyrannosaurid,Tyrannoroid, nothing comes close to size,intelligence,adaptations which is strange at the best
Spinosaurus aegypticaus itself was iirc 3-4t, MSNM was 7.8-8t (this mean if it is spino or not)
From what I currently understand, carchar is 7 tons while “spino” is 7.5
Largest carch was 8.4 tonnes iirc, technically it might be over 10 but that over 10 estimate is based on meraxes
Size and adaptations makes perfect sense when you look at the other dinosaurs Rex lived with.
And may I mind you the size of the mega fauna rex co-existed with?
Source
You can also get 10t carchar scaling off of meraxes too afaik
Keep in mind with the exception of acheroraptor literally every described dino from the Hell Creek formation is the largest of its clade, or very close to it. Like, every single one. It’s kinda hilarious.
I still don't think it really makes much sense to say Carchars are generally larger
https://docs.google.com/spreadsheets/u/0/d/1GVpHchzogtjkTqQrP7PFM2BAWMGHYHABD-Xnk_6KPj0/htmlview?pli=1#gid=0 I got it from this spreadsheet, most people I've asked seem to agree it's pretty reliable
They still get out classed
Preservation bias can also play role in this
given we have several tyrannosaurus that are bigger than the bottom 50% shown here, there's at least another 5 tyrannosaurus as big or bigger than dasp and co. shown here
That chart needs to be updated its been said it shouldnt be used
I consider stuff like that reliable if it at least describes the process of how that was reached or there’s some physical evidence (like a gdi image by someone). This don’t mean squat to me. This won’t hold up as a viable source.
But then again, you have to try and start connecting dots here, Did a tyrannosaur exist in South America? Or maybe a Tyrannosaur moved down there, Even then, there hadn't been much fauna there to support it
In the end it doesn't really matter when the creator of the chart and others have said it shouldn't be used
Megaraptorans are probably tyrannosauroids if that’s what ur saying.
you can see it in their eyes
No I meant the depositional biases. Certain environments stink at preserving fossils
Not only that, but Alamosaurus, a creature that barely migrated into N.America, was somehow hunted in the last millions years rex was around
Hmmmm, interesting
What's this mean
Spinosaurus itself evolved such an extreme water-based lyfestyle to avoid competing with large carnivores such as Carcharadontosaurus. By avoiding to eat any land-based animals, it was able to live freely, without the worry of not being as good as Carcharadontosaurus at hunting. And seeing as Spinosaurids in general would need a lot of time and evolutionary changes to be free from their ties to water, that was the right choice.
wdym hunted? and what is your source that it "barely" migrated into N America
You don't know that Alamosaurus is an invasive Speices?
Barely? They were as far north as Wyoming
no, what do you mean barely migrated
Alamosaurus was invasive?
Debated. A ghost lineage is still a decent possibility.
Ok the 10.5 giganotosaurus estimate is based on a GDI by toxic midget but in not completely sure what the carch estimate is based on, I know none of the estimates are by the guy who made the chart and that it's just a collection of estimates so I will be back once I find a source for the 8.4 tonne estimate
When I'm referring to barely i'm not saying they didn't cover much ground, I'm saying it didn't reach much of N.America to compared the other native species
Likely due to environmental reasons. Alamosaurs (and a lot of titanosaurs tbh) liked open arid spaces. Further north was a lot more wet and forested.
considering the giant mountian range and sea in the way and that alamo is far, far, far, far from special in that regard, I would disagree that it "barely" migrated
It’s a South American radiation so idk
Also considering the Adaptions Rex didn't have to hunt alamosaurus, yet did, means that it would of housed more Adaptions then most Tyrannosaurids would have
We don’t have any evidence of tyrannosaurus hunting alamosaurs. Im not gunna discount the possibility but there was like half a dozen other large prey items lmao.
We do, We have a tooth found in one of the bones
Most tyrannosaurids don't have adaptations for hunting sauropods save for tarbo, that I'm aware of anyway
That means nothing when a dead large sauropod is the equivalent of a whale fall and would likely get visited by every predator in the region for weeks.
you also don't need to have adaptations to hunt something if your base tools are good enough
Kinda funny that these 2 guys belong to the same genus (although the palaeoloxodon on the right is not the best of estimates because the material is missing)
That excuse is used for triceratops, Yet we know that Tyrannosaurs hunted it due to the bite marks founds on Ceratops Frills
I still don’t buy Alamosaurus being an Opithocoelicaudinae
to add to that, healed bone with said tooth would provide better evidence
First of all, said wounds are healed. Second, you miss the part where a sauropod is so big that it would get scavenged by every carnivore in the region for weeks. I can expect a triceratops to get monopolized pretty quickly but you can’t do that with a giant sauropod.
Is someone seriously saying rex hunted Alamosaurus 💀
That’s because we can find pre mortem pathologies, and because they make 40% of the Hell Creek fauna so something must have hunted it
That doesn't excuse the fact that Juvis, or young indivuals could be hunted by Tyrannosaurs,
I do think it's reasonable for tyrannosaurus to have hunted alamo, at least younger ones
^
Hold up for a second, I'm not saying T.rex hunted adult Almaos. I'm saying it hunted the sauropod in general, Regardless of age
I mean I never said they wouldn’t, but you’re really just assuming they did with absolute certainty where there’s nothing saying so. Im surprised you’re not going in-depth with tarbosaurus considering we actually have evidence for sauropods as a major part of their diet alongside hadrosaurs.
Any nerds here know what the Mesopelagic actually zone looks like? How much sunlight reaches it n stuff
Tarbosaurus had the adaptations for hunting Sauropods, Tyrannosaurus Rex didn't, Yet we know that Alamosaurus was still hunted regardless somehow, Even though Tyrannosaurus Rex doesn't have a build for hunting Sauropods
How big was Alamosaurus anyways? I keep hearing like 50 tonnes but I also hear 80 but even sometimes as low as 30
50 tonnes
Down south Tyrannosaurus’s diet is pretty similar, Gryposaurus and Torosaurus in place of Edmontosaurus, and Triceratops
but it's build didn't prevent it from hunting sauropods completely, being worse than tarbo doesn't mean rex physically can't hunt sauropod
Like 40 tons last I heard? I think the giant individuals were misidentified or something.
Don't we have alamosaurus remains alongside rex teeth? (not to say this is evidence of it 100% hunting it)
Okay, so they were misidentified thank you
Considering how large Tyrannosaurs could get and how it's build is ment to overpower other creatures I don't see how it's going to overpower a Sauropod
tarbosaurus also hunted ankylosaurus, but wasn't as robust as tyrannosaurus
They didn't hunt Ankylosuaurs, You must have mistaken it for a smaller species of Ankylosaur that was indeed less robust than Ankylosaurs
How I sleep knowing about the North Horn carcharodontosaurids 
wait do you think theropods kill large saurpods by over powering them? They don't, they wear them down, and I meant ankylosaurs, it was a typo
There is a tarchia specimen that was likely bitten by a tarbosaurus afaik.
Ankylosaurs isn't a specific genus, I believe you're thinking of ankylosaurus
Tarchia is one of the biggest Ankylosaurs
Tarchia isn't as large as Ankylosaurus
theropods would most liekly attampt to take out the muscles in the base of the tail as it's the safest spot and the most effective
How is tyrannosaurs suppose to take it down when it doesn't have teeth meant slice flesh?
by biting the sauropod
It can still rip out chunks of flesh
A robust Alamosaur?
Tyrannnosaurs still have serrated teeth what’s the big issue
Both carcharodontosaurs and tyrannosaurs were giant, slow, muscular theropods with tiny arms and giant heads. They had similar ecology, with the different styles of teeth likely going more into their feeding rather than hunting strategies.
last I checked alamosaurids aren't particularly robust
Carcharodontosaurus had the better hunting stratgies when it came to hunting Sauropods
Who says?
Long legs, Shark Like Teeth, Diet, Hunting Style have all joined the chat
we’re still assuming either one would be going after a healthy adult, plenty of juveniles around
I'm just gonna sit back and watch this.
also rex being worse at taking down a sauropod comapred to tarbo does not mean it arbitrarily impossible for it to take one down at all, just like how an average person can still run despite not being as fast as an olimpic sprinter
Those aren't "strategies" those are adaptations
I wonder if Majungasaurus hunted Rapetosaurus
last I checked hunting styles don't fossilize, it's like saying having long legs to run fast is a good strategy
Half of that stuff isn’t backed up by anything? Also, tyrannosaurids are the more cursorial animals. Idk what long legs have to do with that when trying to gain height on a sauropod in any way’s useless.
Rex would have an extremely hard time taking down a sauropod. It can't flesh graze similar to other large theropods that hunt Sauropods
the juveniles were likely on the menu
flesh grazing is a paleo-meme that has fallen out of favour
Carcardontosaurus have longer legs, giving them a much faster speed then the larger Tyrannosaurs
Exactly
flesh grazing went out of style a while back, it assumes that a sauropod would let a predator anywhere near it without just crushing it
All one larger tyrannosaur
this is not true, nor is that the only adaptation relevant
The current speed estimates have tyrannosaurus as the fastest giant theropod lol. Tyrannosaurids are more cursorial than carcharodontosaurs are.
Not really, the largest giga specimen gets 25 km/h roughly the same as Sue and Scotty
They don't have Tyrannosaur Rex as the fastest Mega theropod, you must be referring to how agile they are.
Also when does running speed matter when hunting a sauropod lmao
Carcharodontosaurs are not as fleet footed as the Tyrannosauroids that much is clear
Okay -- here ye go:
Speed calculation for MUCPv-95:
-
Weight: 8000+ kg
- Optimal Cadence: 1.5
- Optimal Stride Ratio: 1.6
-
Total Leg Length from MUCPv-Ch1: 3180 mm
-
Size Increase estimate for MUCPv-95: 6.6%
-
(T+M)÷F Ratio from MUCPv-Ch1: 1.22 ~= 1.2 - 1.3
- Optimal Cadence: 0.92
- Optimal Stride Ratio: 0.88
- Leg Length of MUCPv-95: 3180 × 1.066 = 3,389.88 mm
-
Cadence Result: 1.5 × 0.92 = 1.38
-
Stride Length Result: 1.6 × 0.88 = 1.408
- Velocity: (3389.88 × 1.38 × 1.408) × 0.0036 = 23.7120207667 km/h ~= 23.71 km/h
So the Giganotosaurus specimen MUCPv-95 has a rough estimated velocity of 23.71 km/h.
tyrannosaurids have a longer proportionally femur length in general
Don't they have a much shorter, robust femur than other theropods?
Read the thing I posted
No. Tyrannosaurids are more cursorial in general. Although, both were already slow and idk what running speed has to do with hunting a giant sauropod.
Tyrannosaurs are leggy monsters
That proves my point, Giganotosaurus is better adpated at taking Sauropods than Rex is
It's roughly the same speed as rex
What does running speed have to not do with attacking a sauropod? The faster and larger you are the more chances you have in attacking them without being stomped
For anyone curious on tyrannosaur leg proportions 
what the hell is being debated rn
Also keep in mind that you’re kinda missing the forest for the trees here when said sauropod quarry between the two was different. Giganotosaurus coexisted with smaller sauropods that were actually realistic to tackle even as adults. Meanwhile rex has the 40 ton alamosaurus.
no, tyrannosaurs are very cursorial for their size
Giga's femur for MUCPv-Ch1 is like
1.43m
Scotty's femur is 1.26m (?)
Hey uh falcon, your smart, is there a source for an 8+ tonne carcharadontosaurus GDI?
Giga had the Candeleros Giant/Monster, a very simarily sized animal (or bigger) than Alamo
Also @clever sable private :)
Alamaosaurus reached 50 tons, and Rex wouldn't be able to used the forest as an advantage if it has to take down the Sauropod
oh, I meant shins, got my bones mixed up
I’ve heard it exceeds Patagotitan
but there is a GDI for it?
Anyone have a GDI of tyrannosaurs rex compared to it's family?
Yea (Ig)
https://thesauropodomorphlair.wordpress.com/2020/06/04/the-candeleros-monster there is a dedicated blog made by SIW
Not seen it personally but...maybe...maybe
So spinosaurus indeed was not the largest theropod in it's environment....... (Possibly)
Im saying that giga actually had realistic options even among adults of the species. Rex only has Alamo.
We don't know that
Newer Tarbosaurus material suggests it got a lil bigger than previously thought as well, for those talking about Tyrannosaurs being small
Nonetheless 8t is entirely possible for carcharodontosaurus
Fair, but there's also the issue of Alamo being a possible wastebasket taxon, where all Cretaceous sauropods in NA are labeled as Alamosaurus
Maybe they all were
Given that the largest spinosaurus specimen might not even be spinosaurus i think there is a pretty good chance it was not the largest theropod in it's environment
Whats also the thing with getting 10t scaling off of meraxes or something? (for carch)
Because there were no present Sauropods in N. America besides Alamosaurus
Nuh uh (doubt it)
Re-read what I said, Alamosaurus might be a wastebasket taxon
To be fair, what else could any other Sauropod be?
Poor Alamosaurus
I know its unreliable but I remember beag mentioned something about it
It could be a new species not yet properly looked at? Idk what you want me to say lol
Alamosaurus sp. 👹
That would change the landscape so much that we wouldn't be able to track it in a timeline
wait nvm random answered it a while back
Hot take: Tyrannosaurus did hunt adult Alamosaurus
The 40 tonne specimen is an outlier, and perhaps as result of being a wastebasket taxon, we have histologically adult individuals that are half as big or less
Speaking of uhhh, dinosaurs what is the general consensus in oxalaia?
It wouldn't because we'd have the same amount of sauropods, they're just differently named 
a waste basket taxon would be a taxon that as material under it that shouldn't be, so alamo might have several specimens which should be a seperated species or genus
the thought of having to deal with alamo (or any titanosaur) being a wastebasket is terrifying
I’m all for Alamosaurus speciation
I remember when Alamosaurus was a contender for largest sauropod 😔
for all we know the southern supposed tyrannosaurus subpopulation adapted to tackling Alamosaurus
That's fair, But again, We can barely track alamosaurus to when it migrated to North America, Image what would happen if they found another Sauropod in N.America?
It'd have to be mostly behaviorially
Another beautiful day without caring about oxalaia
*if it migrated
hey Oxa is valid in my heart
Yeah, again, ghost lineage is a possibility.
titanosaurs are a mess already, there’s a lot of material that I guarantee will get shuffled around if someone actually takes a closer look at it (towards the basal end a lot of things probably aren’t even titanosaurs)
You mean Fakeosaurus?
Oxalaia is valid… a valid species of Spinosaurus haha 👹
also a migration is irrelevant to it being a waste basket taxon
Idk bro, it seems to be spinosaurus, lots of similarities, especially with how the material was destroyed
oh my god this clearly spinosaur might look like spinosaurus, we are entering the Baryonyx/Suchomimus debate
Spinosaurus is the new Megalosaurus
That's a fair point, but again, If it isn't an alamosaurus, what on earth could it be? And if it's another sauropod we run into other problems to when it existed and for how long it existed in N.america
Guys what if nanontyrannus is actually a juvenile spinosaurus
montanaspinus moment
Oxalaia is the definition of fragmentary
when isn't an issue if the specimen is dated, if it is alamosaurus it would be a new species of alamosaurus, or a new genus
Par for the course for spinosaurids lol
acrocanthosaurus tooth in ethiopia:
Maybe it's just Alamosaurus that became more suited to N.America?
korean acro
Spinosaurus itself isn't really that fragmentary
this is essentially the same thing as when troodon was split into laten and stenon, though I afaik alamo itself would still be valid
Also in korea
there were other sauropod lineages present in NA as late as the cenomanian, it’s possible for one of them to have persisted undetected it’s happened before, besides that it could just be another titanosaur that got there the same way alamosaurus did
Spinosaurus, oddly enough, is an outlier in that it is relatively complete for a spinosaurid
I feel like I know nothing about most of the pacific Mesozoic fossil record, what’s cooking over there
isnt Alamo a Nemegtosaur or OPisthocauldine
That's a fair point, or maybe it's just alamosaurus
I like 3D skeletals
If it’s an Opisthocoelicaudinae than it would be a South American radiation
Or well, 3D skeletal isn't actually what it's called, technically it's just called a 3d model
It’s actually a derived sauropodomorph 
I don't think you understand, hopefully this will explain
Oh, alright that makes more sense
Guys i got a question, can i get a comparison of allosaurus fragilis next to allosaurus europeas?
circles represent a specimen
Tysm
Still confused on one thing when it comes to tyrannosaurs rex, Why in god's name did it become so BIG?!
so this sauropod would be another new sauropod that lived with alamo, or just before, or just after, depending on the estimates of the specimens
Because it's prey was big (oversimplification but whatever)
A. amplexus my beloved
Lions would disagree with you
same reason Russia and the US have so many nukes
why did tyrannosaurs become big? well when the local apexes go extinctyou have a power vacuum
Why is saurophaganax sub adult giga sized..
Lions when they get assaulted by a large male Nile crocodile:
The arms race lol
They became big because there was food to exploit and nothing to make getting big disadvantageous
A. maximus (im on the side of it being a basal carcharodontosaurid)
Tyrannosaurs had a power vacum for 10 million years and Rex is the only one to become so large
10my?
Nile crocodile when their very distant cousin gets mauled by a jaguar:
Zhuchengtyrannus may have actually Also gotten very large, there is an undescribed vertebrae that's roughly the size of Sue's largest vertebrae iirc
siats my beloved why did you fail to stop the tyrannosaur uprising
yeah carch is massive
Caimans are fodder anyways
that's it being SCALED with Sue's vertebrae I think
Stop the cap, they can get very large
Large male black Caimans still get killed by jaguars
black caiman specifically
Albertosaurus left the chat
Look trex big cuz it big.
Prehistoric animals are cool, huh? (Just trying to prevent the mods from bonking us.)
Daspeltosaurus, Gorgosaurus joined the chat
No, there is an undescribed vert about as big a sues
and in response its prey got big and trike lost its frill holes
Black caiman, still fodder 
source
You said 10 million year power vacuum, I just filled it
My bad brah
One sec, I posted the link a while ago, time to go find it again
a big enough Black caiman is top of the food chain
Lmao ty
POV: You read "Pterosaurs by Mark Witton"
And now I am become pterosaur fan, critizer of David Peters
All I smell is unreliable 🗣️
i dont know anyone who takes peters seriously
Z-Boomer 
Someone explain to me how Crocodilians neg all land mammals?
perfectionism
Because they're so insanely based animals and only take Ws
Crocodile fanboys are absolutely rampant, ah make it stop
Gustave moment🗣️
case and point the largest terrestrial carnivore of the cenozoic isnt a mammal but a Sebecid Barinasuchus
Paraentelodon enters the chat:
1000kg - 2000kg specimens
Gustave likely didn't kill 300 people and there is 0 proof of him killing hippos actually (I believe the highest number that can be reasonably verified is 60-90 kills iirc, I could be wrong)
not a full carnivore
Fair it was likely more herbivorous/omnivorous anyways.
Birds and Reptiles beating the ever loving sh out of mammals for millions of years:
I agree Gustave is impressive but there's cooler
Birds when they are reptiles
i just want confirmation Gustave is still alive
Me explain to you how birds aren't considered reptiles:😳
Oh dear
they are reptiles
Birds are reptiles
Mammals are dinosaurs
But worse in most aspects
all tetrapods are fish
They aren't reptiles, Archosaurus are repltiles, Birds aren't reptiles tho
Stop the bird debate, here’s a screenshot no need to discuss anything else
you and I know where this is going to end up 
wait isn't that in the same ball park size wise for Barinasuchus
im getting birds arent real flashbacks
Birds are archosaurs, birds closest living relatives of crocodilians and the closest living relatives of crocodilians are birds, birds are undeniably reptiles
Not reptiles, haven't been reptiles
I posted a cladistic screenshot, why are you still discussing this
Alex James has said Paraentelodon was most likely 1000-1700kg but via tooth scaling you can get up to 2000kg specimens
Dinoaurs are reptiles. Non-avian dinosaurs are birds so therefore, birds are reptiles.
Birds are dinosaurs, dinosaurs are reptiles
bro has accepted reality
My bad, I couldn't see how simple that was, forgive me 😦
List of the tyrranosaurids, tyrannosauradae generaky related to trex: zuchyngtyranus, tarbosaurus, albertosaurus, gorgosaurus,alectrosaurus,yutyrannus,nanuqsaurus,lythornax,daspletosaurus,alioramus (did this cuz bored)
Lovely
oh my god the spelling
Yuty isn't a tyrannosaurid btw, its a tyrannosauroid
Oh god
I said generaly.
i feel my autism getting worse
About that Zhuchengtyrannus vertabrae, did anyone bother to check how it scales with the other material?
Reptiles when they are still the most dominant and successful vertebrates ever
Mammals cry in the chat:
Don't worry about it. Now you know.
fish
Reptiles when they meet my big mammalian pet blue whale named Cupcake, it mauls them to death
fish 
Shhhhhhh, fish are too successful we don't talk about them
Also i didnt come here to get bullied for havin autisim and not being english.
then its about the same size Barina is about 1,700-2000kgs
Cupcake when I introduce them to my cute goldfish Megalodon
when i introduce them to Perucetus
Cupcake after being mauled by 15 mosaurus and getting spanked by the Triassic Goat:
Perucetus isn't even bigger than a large fin whale
Not everyone in this server is nice unfortunately.
birds can't evolve out of reptilia
weight averages to 180 tons which if average makes it bigger then blue whales which average around 110
73tons is still massive, now it isn't no 122-150monster like megalodon
180 tonnes is outdated
Nothing is bigger than the blue whale right now, Even the sea potato didn't come close
if birds aren't reptiles, neither are all archosaurs
If something on land even had 100 tons it be so heavy it collapse on itself
your mom is though
argentinosaurus
I agree Perucetus is cooler than meg
it was downsized to 68-73tons
You're mom broke my pelvis that it became IRRATATING to reconstruct,(reference to irratator)
your* 
Not 100 tonnes (although the collapsing under itself has been disproven for sauropods iirc)
irritator finds these jokes very tasteless
Irritating* 🤓
You mama so fat the planet dosent hold her on she holds the planet
You're mom so large she out weighs the largest sauropod by twice it's weight
Wow you’re such a meanie pants, I’m calling daddy
Noo this is turning to your momma roasts 
yeah I swear it got downsized like the day that it got described💀
It did, it took like 4 hours
Favorite prehistoric creature that is not a dinosaur. Go!
if the heaviest blues could be around 200 then 180 isnt out of the realm of possibility
Megalina
Paraentelodon 
Your mum
Sarcosuchus or purussaurus
Hmm Deinosuchus
Honestly id not be surprised if dinos were still alive that theyd be food, imagine nickacado avocado did a muckbang of eating 100 deep fried compys and a whole carnotaurus worth of steaks
probably columbian mammoths
Blue Whale extends into the early Pleistocene right? That’s my favourite then
Brachiosuchus...maybe Kapro/Mahajungasuchus
180 tonnes has been thoroughly disproven, far too much soft tissue was added to the model used in the paper
Anteosaurus
anteo is great..tied with Erythosuchus and Inostrancevia for best large permian carnivore for me..no wait Erytho is Triassic thats right
They also used manatees as the analogue for perucetus when they should have been using close relatives.
Funfact: Manatees aren't even chunky its just they have massive guts + the amount of food they eat.
Aren’t the guts massive because of how much they eat, and what they’re eating ?
Speaking of aquatic, I had a question about how much light reaches the Mesopelagic zone 👀
sea grasses
Some huge prehistoric Crocs and stuff (the deinos are outdated)
paraentelodon v hippo comparison
whys Smilosuchus on there...its not even Psuedosuchian
Idk ask random
mm fair enough
Damn, I’m left empty handed again darn
every creature is cool beside sarcosuchus (lame)
Abuse
id argue there no such thing as a lame animal
its to spite fred, sarco is cool yeah
Sacro sucks as a crocodilian, It's a crocodilimorph
sacro...the alternate name to scrotum humanum
Crocodylomorphs aren't even well known
Sarcosuchus compared to various creatures in it's environment (because I did this on mobile it may be off so instead of trying to make the human models the same size o made the female model slightly smaller than the male one as I believe it is smaller than the male model but if it's not the sarcosuchus here is slightly too small)
scale one with paraentelodon (its 3m) 
Deinosuchus, the much cooler verison of sarco, Chadly walks into the chat, smacks the sh out of sarco, and leaves:
Sarcos cooler
deino is not even close to sarco
15 ton estimate:, Larger biteforce:, Cooler prey:
I mean, it is far larger but sarco is way cooler
ahh yes the child argument that size and bite force =cool and not just its cool cause its a animal
15 tonne estimate when possibly completely incorrect
Do you want me to explain how a deinosuchus would mop the floor with a sarco?
How well a creature kills things or what it can kill is not a very good way of judging how cool something is
Not only that, wasn't it proven that Sarco couldn't do the death roll? Already an L
no cause i know what would happen cause common sense due to Deino being ADAPTED for vastly different prey while sarco is a gharial in behaviour most likley
yeah but it depends on the type of death roll
Welllllll, https://youtube.com/watch?v=UtH6u2VbgM8&feature=shareb https://www.youtube.com/watch?v=FT5UmbBUc_k
sarcosuchus may have actually been able to perform death rolls while feeding and it almost certainly could perform violent thrashing motions, isn't DRCI is very similar to a tomistoma (DRCI stands for Death Roll Cranial Index) and tomistomas can preform death rolls for feeding and will preform violent thrashes while hunting while having a pretty thin snout it's not completely unreasonable that sarco may have used a death roll to feed and preform violent thrashes on prey
Currently the Tomistoma is listed as vulnerable (population decreasing). Bronx Zoo is on a mission to help contribute to the population by getting Priscilla the Tomistoma to lay some eggs.

sarco isn’t particularly similar to gharials when it comes down to it
i meant more to probably specilized more for fish
While feeding, can't do it when the prey is still alive?
fredthebaddog when someone calls sarco a big gharial: 
also sort of unrelated but there’s undescribed brachiosaurid remains in the same formation as sarco
I am not looking at all of that brahhhhhh
elrhaz? nice
besides both are cool but not not cooler then Sebecids and BAurusuchids
Crocs don't use death rolls to kill things the majority of the time, it's actually a method of breaking up food to eat
Sarcosuchus had a generalist diet, this is confirmed by isotopes in the teeth
i just remember when due to its gharial/tomnistoma like snout it was debated
To be fair, when comparing this to deinosuchus, it's not really a fair comparison, Deino was simply more robust and much better at handling larger prey
i literally said deino is adapted for vastly different prey
Deinosuchus hatcheri when it most likely primarily ate turtles:
(or at least they made up a good bit of it's diet)
Deinosuchus munching on a tyrannosaurid:
That's schwimmeri that did that, not hatcheri
missing Riograndensis
I'm referring to Deinosuchus as a whole, which comparing both of them, share minor differences
size difference is noticeable
Except deinosuchus shwimmeri is like, significantly smaller
I'm still forgeting on how both of them didn't much on tyrannosaurids?
Invalid, thats Been lumped into hatcheri
see i knew it was contested or synonimized by now..its just the better name...
I don't know if I like purussaurus or sarcosuchus more, both are just so cool
Purussaurs is a beast
downsized sadly
11 meters and 7.2 tonnes for the largest specimen
Real talk, God must have spawned the most devious caiman to ever exist, with prey having no real way of defending themselves
i mean it had huge turtles so..
Paraentelodon is real cool talk. Heckin massive beast.
It ate huge turtles, probably prehistoric capybara relatives and ground sloths (at least this is speculated to be the case) it also had serrated teeth
Hold up, Has anyone realized how scary it would be to find a large crocodilian just near you're boat?, that's straight up demon time
australia isnt worried so why should i
Purussaurus is very cool
You when a 20 foot crocodile lunges out of the water to eat you:
stay away from the water its common sense
Cheetah Gator would love to learn about you're location, Kaprosuchus
correction its cuban crocs
OH HELL NAH😭
aww its cuddles
Kapro was not actually super terrestrial, it was probably about as terrestrial as modern crocs
It still was better adpated at a terrestrial life-style compared to modern crocs
we dont know
Nope, not really, the whole terrestrial thing was just based on it's eyes but it being more terrestrial has since been disproven
Why did pot make allosaurus europeas look fat and larger than fragilis.
Oh, cool. So you wanna talk about the carolina butcher?
not a crocodile..hell might not even be Psuedosuchian
fair point
Also, real talk, Is the Pt Rex Bigger than The Pt Giga, I've never been able to find a comparison between the 2
if you want a running crocodylomorph you literally have Boverisuchus or Sebecids
I still want to see if you guys have any personal input. Because anytime I see them I always see Pt Giga being much bigger
height wise giga more then likley did tower over rex but all in all rex is the heaviest theropod
This is pot we are talking about, doubt any of the mods have the brain-cells for that
yea and PT makes theres actually decent to each other
I don't know if the Pt mods made sure to make Rex larger than Giga,
they are the most accuracte in size to the real animals
Giganotosaurs looks much larger than Rex though, And rex looks as if it's based of more gracile morphs instead of the bulky ones
cause giga was taller and maybe they used specific specimens for rex
aren't rex and giga the same weight with giga being slightly longer but thinner rn?
It looks as if they used the largest Giga specimen and the semi largest rex specimen
depends on which specimen, dentary specimen basically, the holotype for giga is bigger than the average rex though afaik
The largest Rex is still bigger than, idk, every other megatheropod know in bulk?
carcharadontosaurs just had bigger heads while rex was just a solid block
Guys Im asking if they made Rex bigger than Giga when they modded the animals, It looks as if they made Giga bulkier and larger
its stated they are semi ficticous but they said the sizes are accuracte so im running with it
The largest known giga specimen may have been the same size as Scotty and PT rex is based on sue
So they used the largest Giga specimen and the 2nd largest Rex specimen?
Ye
sue is better then scotty anyway shes actually cool
I hate when they do that, and they always use the gracile morph as well
PT rex is accurately chunky
hell the slim ones decently round
It's not, it doesn't even come close to the size sue was
the gastralia on that is bad afaik (its backwards innit)
That recreation accidentally put a gastralia on backwards and made it too deep
I grabbed the newer one, nvm. My bad it's older
My point still stands, It has a very big head and a very round skeleton, Pt puts to many skinny verisons
it isnt shrink wrapped so stop complaining
Why can't I complain? People really downsize rex when it comes to sheer bulk, but never skip out when it comes to Giga's size
She's not even too skinny, it's a regular amount of soft tissue
thats what im saying its not too much or too little its just average soft tissue
Sue isn't downsized, she's properly chunky in game, PHP rex, saurian rex and even the sue model are all too chunky
Try again, they have a much skinner verison in game, and one with teeth
yea thats the problem they overemphasize the chunk
Those are alternates, the base is fine
The default one is a regular healthy amount of chunk
THOSE ARE COSMETIC AND SIMPLY FOR DIFFERENT LOOKS
Alternate could still use a bit more bulk, it feels as if it's a sized up dasp
They have an alternate version that adds so much soft tissue it looks obese
why does everything need the max soft tissue as if its fat..
It's not obese >:(, it's sue's normal appearance
PHP rex has wayyyyyy top much soft tissue
its not sue its BASED off her
any opinion that reduces Tyrannosaurus in game to a "sized up das" is an opinion I don't give weight to.
That could also go for how large the Giganotosaurus is, Being much more barrel bellied then a rex, A REX
That's not what sue would have looked like, this is a regular amount of soft tissue for Sue (due is on the top)
Oh god, I can already smell the 8.8 ton estimate here
what are you talking about dude
probably cause thats average...
This reconstruction of Sue wouldn't be able to hold 9 tons, let alone 10, Scotty maybe, but using this is a strech
That isn't an 8.8 tonne estimate
with all due respect, you don't know what you're talking about

if sue cant then scotty couldnt but both are roughly around 10 tons as OUTLIERS
No, that's just what sue looked like
Idk if anyone's GDI'd hartman's version but I don't believe there's anything wrong from it.
With all due respect, the bulk of a tyrannosaur has been missing in so many reconstructions, This thing gets outweighed by the dentary of Giganotosaurus
It's almost like the dentary of the giganotosaurus is the size of Scotty
This is why I love Dan Folkes Gdi of Rex
oh I guess there is a dorsal view of this one
People tend to diss hartmans skeletal when he has if not the best access to the material when making these.
folkes's gdi isn't even of sue
Oh dear god, this thing shows teeth and had no lips, it looks as if she been shrink wrapped to look as if she's an average Tyrannosaur, It looks similar to Stan more than Sue
It's no different, this is Scotty
That rex is bulkier than the rex shown above, you admited into using a shrink wrapped version shown previous
homie its a skeletal. here have random's instead
that's an old scotty btw
It's the same amount of flesh, just a different gastralia position, no offense but I really don't think you know what your talking about
my god its like arguing with a wall
"shows teeth and had no lips" it is a skeleton and it is closing its mouth
also nice pronouns riotin btw I think I'll write you off as a troll
I think you guys are trying to argue that the Rex that Pt made is fine, it's not, And I still asked is the Pt rex larger than the Giga one
i said twice giga is taller
I bet you think Prehistoric planet rex has a normal amount of soft tissue
My god, I'm not talking about their real life couter parts, I'm referring to PATH OF TITANS, AND THE PT MOD OF REX AND GIGA, which one is larger?
and pt mods are size wise accuracate
go into the game and find out. this is paleo chat
They are roughly the same size, although if PT giga is the same size as the dentary specimen than the dentary specimen is larger as the dentary specimen is Scotty sized
Doubt the rex is size wise accurate considering how it pales in size compared to Giganotosaurus
REX WOULD LOOK SHORTER BUT ITS HEAVIER
We are going off base models, Rex looks as if it's smaller than Giganotosaurus
Scotty compared to giganotosaurus (the Scotty here is slightly too small but nothing absurd)
me when questionably scaled dinosaur is not even 1% larger than other dinosaur
Yes but it is not, this is due to giga being Long and taller, however in terms of mass rex is bigger
I am asking, for the last time, if anyone can simply bring both models and show which one is larger? AS IN THE PT MODELS
go to modding for that
or go into the game
Mass isn't always a completely visual thing you can just see by taking a look, bone density also has to do with it
When it comes to large animals it's very easy to tell what's larger and what's not, Except sauropods
Ehhhhhhhh, sometimes, but not always
evidently not since giga and rex have very different dimensions to them yet net out to be similarly sized animals
Wow I clock out of work and we’re still on this.
my brain hurts..
Gorgosaurus is cool can we get some hype in the chat for gorgo
a. libratus
Albertosaurus libratus 
nah Thantothorestes
d. degrootorum
glue eating crew came out real strong immediately
I trademarked "glue eating crew" you can't have it
"alamotyrannus"
t. sp
as a glue sniffer i feel validated
Back
I like acrocanthosaurus tbh, easily my favorite dinosaur
Fran is a beautiful lady
After looking at both models, I apologize for being harsh, it's just that the Giganotosaurus looks so much bigger in mass, when you know, Rex just got proved to be the largest theropod and what not
I'm a guy but I do like wearing dresses sometimes
acrocanthosaurus is cool with maybe being an asian immigrant to NA
korea
Acrocanthosaurus sp. my favourite Dinosaur
Facts
acro is a very cool dino
also Acro taking over the entire south and eastern US
Also, 10.5 estimate for Giganotosaurs does not exist, and I've went to the spread sheet where Dan Folkes did he calculations for the theropod, and all I found was 10.4
and whatever the hell capitalsaurus is
10.5 is based on a GDI by toxic midget who helped with the blog
probabaly acro
Is it accurate though?
Are you getting up in arms about 0.1 of a tonne? Probably just people making translation errors it’s so inconsequential
also its dentary scaling
which is cringe
Seems to be
I mean in the blog its literally 10.4t it is such an indistinguishable difference at that size
Yeah that’s the issue.
Seems to be other wise, I've heard it's either the same, or people clown on folkes for using Dentary scaling ( won't accept Giga being bigger)
need confirmation for someone...Ostafrikasaurus currently leans more towards Ceratosauria correct..im not crazy..maybe a little
Except that dentaries can vary between individuals so it’s unreliable.
He just made an estimate, I’m pretty sure he made sure to clarify you don’t take any of them as the absolute truth
I mean, it's still not the best estimate of all time, not because of anything Dan folkes did but because of how fragmentary it is
You know what, someone make an estimate on that Rex toe bone
ceratosauridae but its a dumbass taxon anyways
You get like a 15m rex or something insane. Osta’s a dubious ceratosaur.
arent all tooth taxa
yeah but the name's dumb too
Cladistically placing teeth 
its not the worst
What if that toebone was a 15m rex? What if Spinosaurus did reach 12 tons? What if Giganotosaurs was able to live 40 years??????? Crazy times we live in
what if batman came and saved the day
Isnt the 40 years part proven tho?
I was there, all of it happened
how is giga being 40 crazy..
a frenchman names a tooth after the german term for east africa decades after germany left frica
What if sarcosuchus grew to 11 meters
Giganotosaurs just lived very long lives. One of the Meraxes specimens was in its mid 60s when it died.
Considering how Early rex dies, Doesn't Giga live to 50+ years?
pretty sure it didnt have rexes grow fast die young policy
Btw, does the suchomimus holotype being a sub adult claim hold any weight or nah?
Guess that's a drawback to being the largest theropod, Live fast Die young
Trexes partied hard
I honestly have never actually seen the source on it, ever, so I’m inclined to say no.
It's moreso their lifestyle, Tarbosaurus took 40 years to reach adulthood (or at least, skeletal/sexual maturity?) vs Rex's 20
What kind of vietnam stuff did I just say>
yea rex was special
Hi
Eh not quite. Last I checked acro and most other NA tyrannosaurids were similar to it.
Rex died at like 30ish smth right?
The oldest we have is early 30s, yes
It would be very interesting if it was because it's already about a ton larger than sarcosuchus
Wait, Guys, Does anyone share the same theory that Megalosaurus were just apart of the tyrannosaurdea family?
the oldest also happen to be the largest I believe yess?
no..megalosaurs are very obviously not Coelurosaurs
Sue’s 28. Idk Scotty’s age if that was ever determined. I know the oldest rex was neither of them.
Yeah no, that's a hard no, as far as I'm aware nothing actually supports this
I want someone to ship to me because I don't know. Please, I will owe you 🥲
I swear the jaw of Megalosaurus looks as if it could be mistaken for a tyrannosauroid, maybe they just evolved similar appearances
ahh that was my mistake. I thought sue was older
isnt our oldest rex like 31
Probably just convergent evolution ig
no it's 30
Megalosaurus isn’t just a jaw, and there’s plenty of more complete large megalosaurids that make it a definite no. They got this unique body shape tbh. Almost baguette-shape lmao.
🥲
put the majungasaur in the megalosaur for a sausage baguette
Why are you asking in Paleo chats.....
And may I be mistaken but, why didn't tyrannosaurs just move to south america?
It can’t be just me, especially with how the head looks
natural barriers...other large theropods...also theres only Santanaraptor which is suggested as a tyrannosauroid i think
because central america was a bunch of islands and crap
If I know how I will do🥲
There can be a whole load of reasons. Taxa aren’t obligated to interchange. Crocodiles can swim across oceans when motivated enough but they don’t (often) for a more absurd example.
well you might have santanaraptor as a tyrannosauroid if that thing ends up as one
yea i think its suggested but not concrete
Image if Rex moves to south America, and you know, Dominated the entire place
Even then that’s tyrannosauroid. There’s also timimus of Australia and megaraptorans.
and Eotyrannus and maybe Nuthetes in the UK
and kakuru and that unnamed pubic thing and the many other things of questionable tyrannosauroid placement
What would you say the most successful group of theropods was?
If the tyrannosaurs could take Asia and North America i'm sure they could take all of South America
birds..so maniraptorans
Yeah you got us there
dinosauria
Birds got lucky though, If we want to be specific it's the sauropods, they were almost untouchable. NVM HE SAID THEROPOD
Is bro seriously treating dinosaurs like different factions in a Mobile game
In terms of non-avian dinosaurs I’d probably give it to ceratosauria cause they were the first major theropod clade to evolve and they were ever-present to the very end
"they could take south america"
Look at this, Zenob is a god send for providing it
Tell that to the illgeal tyrannosaur immigrants that went to North America
even then at the end they were stuck in the south with only a couple up north
definitely not a weird thing to say
Eoabelisaurus is so friggin odd to look at. It’s a spitting image of an abelisaur but it’s 180 million years old. Skip forward to proper abelisaurids in the early Cretaceous and barely anything changed
eoabelisaurus also might be a ceratosaurid
Crocodile vibes
Bro what, oh god, get this awesomebro outta here, you gotta focus on them as animals, not as killing machines, also wtf does that even mean "illegal tyrannosaur immigrants", like, what the hell?
Eoabel looks rather standarnd then you look down looking where it all changed
we do have abelisaurids in lourinha and tendaguru that are decently sized
i uh did get intel on Turkana
Lourinha 👀
any "titanovenator" enjoyers in chat
titanovenator sadly wont be the name
it's a couple teeth but still
Pronto you take that yawn back
he might be a insomniac
Abelisaurs are pretty cool tbh, idk what my favorite is but I gotta go with majunga or carno, call me basic they are awesome
i like thanos because I hate it and it was getting murdered by a giant megaraptoran
although said giant megaraptoran may or may not have been getting murdered by a giant abelisaurid
uh Llukalkan for best Abelisaur name..Ekrix cause its fun to say, "titanovenator" cause possible rex sized abelisaur, oh wait no Kurupis is great too
Quilmesaurus
kurupi is awful
nah its the "rock hard sex god"
1, I don't know who or what awsomebros is 2, You need to understand that as animals they take over niches in order to make their living suitable. You really think if a tyrannosaur managed to enter South America it wouldn't be able to establish a niche their as an apex as the previous apexes pretty much went extinct giving the Tyrannosaurs a much easier time taking over a niche free environment. They already did it in North America once the Allosaurus died out, and took of all of North America leaving not much to be filled but themselves. The only other theropods we know for a fact co-existed with tyrannosaurs was Dakotaraptor and even then it was a mid-sized animal with estimates being at least 800kg. You need to stop taking what I say as a joke and stop acting as If I want animals to fight to the death. I asked I question and you couldn't give a straight, mature answer and instead insulted me. And not only that my point still stands, If tyrannosaurs migrated to South America they would have been able to evolve traits for them to take over. That's what any animal does, it's not subjugated to tyrannosaurs alone
where did 800kg dakotaraptor come from
Yeah, that’s terrible
your pronouns are "nick/her"
not my fault it was found by a love hotel
It's based of the largest individuals at best
Right but they had the choice to not give it that binomial name 
the largest individuals which might be Unenlagines
What is a unenlagines?
Oh? The radiation of Unenlagines continues?
austroraptor and friends
Dakotaraptor doesn’t exist.
You seem to really only care about how big stuff is and how well it can kill things and that's literally what an awesomebro is and you constantly say "oh it could mop the floor with them" like, what?? How am I being the immature one when you're "pronouns" are literally "nick/her"
For god's sake please don't say it's a turtle
more just depalma's cringe
Dakotaraptor exists, it just might not be as big as claimed or it could be a different family and thus reconstructed differently
or might not exist in that it may get a name change
I’ve seen Dakotaraptor can confirm it has a testudine carapace and everything (real and true)
they let you see it? incredible they keep that thing on lockdown as if it wasn't real or something
the area 51 for dinosaurs
meanwhile in depalma's dungeon
Put on one of those joke glasses with a moustache, they didn’t bat an eye
me waiting for sereno to give actual measurements
go to serenos for more crocs
That doesn't excuse how you weren't able to give a straight answer. Calling me an awsomebro because I am curious on how large theropods hunt is the dumbest reply you could have given. If you don't want me to say Deinosuchus mops the floor with Sarco that's fine, I'll explain how it uses it more jaws effectively in order to rips massive chunks out of it's prey, and how it's size is almost comparable to that a sarco, with much more adaptions used to take down large prey
Less the turtle part, which was fixed pretty quickly, and more that DePalma’s an embarrassment of a scientist that fabricates evidence and cannot be trusted, especially when he refuses to let anyone outside his circle look at the material directly. There probably is a larger raptor in HC but there’s nothing to suggest it isn’t a large acheroraptor or something.
Lol
its just a big atrociraptor
5 metre Acheroraptor is real
Wdym a straight answer? I called you an awesomebro because you only seem to care about them hunting and killing, also it doesn't change that you saying "illegal tyrannosaur immigrants" is ridiculous and nonsensical
Even then, depending on how you scale it, it can go down as low as deinonychus size
god I hope it does
i have a dream where achillobator finally gets a better description
Keep in mind this was also before DePalma was caught stealing the work of another scientist and fabricating data so it wasn’t obvious he stole from her. He cannot be trusted and thus Dakota as a whole is mute.
common depalma L
Hunting is an everyday thing animals do, Herbs hunt for certain plants and Carnivores either hunt for corpses or hunt their prey regardless of their adaptions ment to counter them. Of course you think being beyond that point makes you smarter than most
It’s all about that missing mid-sized carnivore, what if Albertosaurus dipped its toes into the late Maastrichtian
No I just think that only focusing on killing is super dumb, also you have still not answered what the hell you even meant by illegal tyrannosaur immigrants
I think it might have? I’ve heard something about teeth from that age before.
more albertosaurines would be cool yes very
we only have two, arguably synonymous on a generic level
someone better not say periculosus
isnt there the theory Tyrannosaurus or at least tyrannosaurines asian immigrants who outcompeted Albertosaurines
Also hunting isn't an every day thing, not even close, saying creatures hunt every day is kinda ridiculous, meals can last weeks in some cases
I think it’s at least present in the latter part of Horseshoe
It’s an idea but not really founded on anything outside of coincidence.
