(Not to mention, given what modern Komodo dragons can do, megalania taking on prey as large as lambeosaurus is possible)
Megalania is venomous, though, so maybe just buff its venom so it would still be viable
Megalania’s only real issue stat wise is it’s awful stam. Even then it being smaller would likely benefit it in being harder to hit when it’s ankle biting.
I’m aware
Do Komodo’s have good stam irl?
Monitors in general have the best stamina of all reptiles.
I apologies, but as per rules we don't allow posting any kind of gore or dead animals, so i will have to remove the video! Thank you for understanding.
Ok nice
It's Labor Day weekend, I can now fully lose myself in mapping out passeriformes 
Definitely a way to spend Labour Day
what does that emoji mean
You spelled labor with a U 
Ohhhh
And the players have entered the field
I like to believe that herbivores like Triceratops and Ankylosaurus evolve to actually counter Tyrannosaurus rather than being the other way around
it was probably a mutual thing afaik
^
@tough parcel do you have the rex paleoloxodon comparison handy?
god bless
I'm guessing that's not the palaeoloxodon that's based on the missing femur
Narp, specifically avoided that
Not sure on the validity of this, but I heard that there may be been Allosaurus teeth marks on some bones that were thought to have been "chewed" (chewed in quotation marks since they couldn't actually chew) by Allosaurus. Is this true or nah?
It’s a mutual relationship.
Alr so I wanna get good at paleo art, BUT I drew an inostravencivia without reference or fossil whatever, is this good paleo art?
I feel like the nose ridge is to big maybe, I don’t feel like changing it but I’ll make more so
Looks too dinosaur, what with the brow scales and, well, any scales at all. Like a T. rex with fangs
yeah it looks more like a strange tyrannosaurus than a gorgonopsid. the teeth extend too far past the chin, too - or maybe it'd be more accurate to say the chin's too shallow?
sidenote, i might be wrong here but it feels like having the canine teeth hangin' out wouldn't be very good for 'em? like, idk maybe i'm opening a whole can of worms here a la the smilodon situation, but generally i'm of the opinion that if there's not good reason for the teeth to be out, it's probably safer to assume they weren't, and inost's canines seem just short enough that they could, perhaps, be covered...
Witton wrote a whole blog on it, but it’s been actual years since I’ve read it so
I believe path of titans reasoning for megs awful stam is that monitor lizards cant breathe while running, which isn't true for some/most cases, it just so happens that the komodo dragon can't do it
the komodo dragon can do it tho
As others have said, it looks far too reptilian. It’s talented art for sure, but the scales, bosses, and what appears to be a visible antorbital fenestra are all very dinosaurian traits.
Especially the antorbital fenestra, which only archosauriforms have. It’s also only really that prominent in theropods specifically and likely wouldn’t be outlined when covered with tissue.
Also, like others have said, the teeth didn’t extend that far and probably were at least mostly covered.
I want to highlight again though that is is still very nice art, just not really a good inostrancevia.
can i know who knows Prior Extinction in Roblox?
oh, yep, it's absolutely good art! not accurate doesn't mean it's Objectively Bad, the style's quite nice
I want to make sure that point still gets across, since I know a lot of folks feel discouraged when people point out issues with their art. I think you should absolutely continue making stuff like this if it’s what you enjoy, and you definitely have a knack for it.
Also ik paleo art is completely accurate but it’s my fault for adding the longer teeth because it looked cooler, that was just for fun, and this drawing helped me figure out how to shade and draw properly ish on procreate, thanks for y’all’s feedback!! Highly appreciate it
So since it’s not exactly accurate, I’ll just say this was a detailed sketch for fun, helping me get into paleo art
I wanna see this one day☹️✌️
Is that the specimen at the natural history museum?
Idk lmao
What the heck
I think someone needs to take it upon themselves to change how people view therapsids
What are therapsids
A group of synapsids
Ok Ty
i know this would probably be hard to know but, could Attercopus fimbriungus spin webs or would it hunt more like a jumping spider/wolf spider?
Probably hunted on the ground
do we know when web making developed?
Around 1989 according to google
No one correct this please that was such a beautiful answer
Thank you sir 🙏
200+ foot spino moment
Ignoring the blatant disregard for anything scientific, why do all those old dinosaur docs feel the same?
Lile the cgi and the weird washed out look on all the environments is pretty consistent among them
Depends which dino docs youre talking about
I suppose you’re making an exception for the walking with series’s right?
Yea
The way this Carcharodontosaurus looks so insignificant
I like the carch look here, it was fighting godzilla so no chance.
It's Better than PD carch imo
Whats pd, prehistoric dong?
My thoughts exactly
Planet dinosaur
Nah, PD has a cooler carch.
Nah because it loses to spino
It tied and didnt die of infection.
I do like how it's colorful though
To be frank I don’t remember any of these documentaries
Yeah but it was still fish eating spino
It was basically a sailed crocodile brown bear
10 metres onchopristis
Speaking of terrible dinosaur documentaries, weren't there actual scientists brought on to Dinosaur with Stephen Fry? Wouldn't those people be discrediting themselves?
F for Susie Maidment
Yeah, she was the person talking about allo right?
Ironically, considering she's a stegosaur specialist
I hope they payed Susie enough for her to talk about bullsh#t
I like pretending that doc didn't exist
Bruh I remember watching it and was immediately disappointed like 💀 worst documentary off all time
Id rather watch Monster Resurected than that thing.
Facts
Monsters Resurrected did bring us a very good looking Acrocanthosaurus -- not the green one. THIS one:
How big was T.rex? New data shows that the T.rex E.D. Cope, the "Copium rex," was the biggest theropod ever found, increasing theropod size limits to new heights. T.rex was a powerful predatory megatheropod. While Sue and Scotty are currently cited as the biggest T.rex specimens, new measurements of E.D. Cope, from the Black Hills Institute in S...
Well . . . Never thought I would see the day when a tyrannosaurus is named "Cope."
._.
I think you should not be so rude, I took time to draw that and the response I get is “what the heck that’s not how you draw that”. Smh.
its bigger then scotty, its telling him to cope
Yeah sorry retrospectively it was definitely rude, I left my intended reaction under
I can’t watch the video rn someone give me the tl;dr of what it’s saying and if it’s reliable
Yeah cuz I want to get better at paleo stuff but I want feedback but not that, thanks for apologizing tho!
And I’ll redraw the ino, make it more accurate
Basically, it's saying that we have a potential 13.3 m long, 12.4 tonnes tyrannosaurus specimen through fragmentary remains named "E. D. Cope."
Not sure on the validity of the specimen, so can't comment on that front.
Hey just wanna let you know it’s still very pretty art, honest truth
Thanks, and yeah it’s not accurate XD ik I didn’t use any reference or skeletal whatever so, lol, thanks again
video is good
The measurement available lacks the reliability required to establish a consistent scaling method.
Does anyone know how fast Scelidosaurus could have ran. I have searched for a while but can’t find anything and was wondering if anyone knew.
how heavy was shant ?
15 tons
i have a question, can dakotaraptor and Bruhathkaysaurus be consider prehistoric cryptids?
I wouldn't say that. Being dubious is different than being a cryptid
oh, okay
We know they exist, cryptids we dont.
they're cryptids but both exist in at least some capacity though dakotaraptor is barely verifiable besides some teeth and vertebrae(?) while bruhath has really crappy figures
i thought dakotaraptor didnt exist, neither did Bruhathkaysaurus
Cryptozoology is a pseudoscience. I wouldn't equate them to pseudoscientific creatures of imagination
dakotaraptor "exists" in the sense there was a medium-large dromaeosaur in hell creek
problem is depalma's a royal piece of work and likes to steal/make up stuff so we can't really trust him
ooh
Meanwhile bruhathkaysaurus' material up and disintegrated
and the ilium's probably a theropod
was there any actually evidence of the material existing?
I think there's photos
It could be an actual science if the scientific community would actually take a crack at finding the more plausible ones (Not stupid things like Blob Bob or smth)...tbh Bigfoot's the only valid cryptid, no others exist
giant squids.
bruhath photos
the giant cephalopods are the only things of myth or crypotozoology I would even entertain as valid and studied proper by science, because, well, they are lol
Theres some really stupid ones out there for example this one which is literally just a landslide
Ah my favorite cryptid, Architeuthis dux
i know this might be a stupid question but would dinosaurs have the ability to get Alopecia?
What's that
it makes you bald, just like this bear
We don't even know if it's large as the measurements could just be greatly exaggerated
if birds get it then yeah perhaps.
Balding mynas, it makes their head bald i think
Bruhathkay was an animal that existed, and was huge, likely around argentino’s size. That’s about all we can say about it though.
Meanwhile Dakota is either a dubious taxa to be ignored or is just a larger acheroraptor specimen.
luckily we have the very well drawn figures
I don't think the idea of it being a large acheroraptor specimen isn't really supported due to differences on the teeth iirc, I could be wrong though
There’s been various estimates given to Bruh. I go with the original interpretation that revalidated the taxa. The only other paper that goes into Bruh size is one by GSP and Larramedi which I heard wasn’t that great so I ignore it.
The scaling is likely off by a good bit
We also don't have any actual fossils anymore from Bruha, correct?
Saying it’s about argentino size and leaving it at that is pretty simple and vague enough for a taxa we barely knew anything about and whose remains are no more
could Attercopus fimbriungus spin webs or would it hunt more like a jumping spider/wolf spider?
would it even have the ability to make a leap like that seeing how large it was?
I wouldn’t even attempt to ascertain any mass estimate at all.
Btw, apparently, the fossil that is used in the "Cope Rex" video above is a BHI fossil.
Wait where did bro get 13.3 meters and 12.4 tonnes
He explains in the video.
Replying to it so that ye can get to it easier: ^^
Also apparently there may be one even bigger than cope if this statement includes cope
Femur circumference measurements that were from GSP's 3 rex species paper.
ah, this is just the upper end of the error bars
I thought he was claiming a 12 t rex was conservative, which. No.
He did the upper end based on how Scotty's GDI mass is higher than the femur circumerference baseline
weird method but ok
Nah, he said 10.7 was conservative iirc
The methods are fair enough but I ain't gunna parade around a 12 ton rex lol.
Of course, a proper study into it would probably be the best to determine whether or not Cope was bigger.
Personally im just gonna say it may be 12 tonnes but around 11 is more likely
Wait a moment -- Randomdinos, didn't ye and the JFD team come up with a heavier tyrannosaurus before?
The JFD tyrannosaurus added too much soft tissue iirc
Wow, these are the discussions I live for. Mass 😐
y yes, mass
Synchro came up with a 13 t rex, I said absolutely not and we whittled it down to 11.4 t
No dorsal fin? 
Well now maybe a 13 tonne rex isn't impossible because cope MAY be 12.4 although I do have my doubts
Its debated whether or not shastasaurs would've had dorsals. It would work out phylogenetically but most massive marine animals lose the need for them.
yeah, just don't consider the 12.4t one lmao
Reduced one?
possibly
Ehhhh, I mean, I will mention it but for now I'm gonna go with ~11
Considering dorsal fins in Ichthyosaurs, what’s the largest one with a preserved dorsal fin?
I'm interested in seeing how large Bertha ends up being
Going by the mounted foot bones I am skeptical that she will be very big. But foot scaling is foot scaling
If she does end up being 10+ tonnes that might mean 10 tonne rexes weren't as rare as we thought
I see. XD
I'm assuming ye were mortified when ye saw that Synchro said the Rex was 13 t?
I had to show my Sue multiview, which was a private commission (at least an outline of it) in the end. But it worked
The only reason I consider it is because of how insanely wide it's femur is
I'm aware, it's only 7% wider than Scotty
Well, assuming that means the whole creature 7% bigger than Scotty you get a big creature, not 12 tonnes big but still huge enough that if you add a decent bit more soft tissue you can probably get 12 tonnes seeing that using the skeletal you made JFD was able to get 11+ tonnes for sue
a little over 11 is achievable if you put some extra tissue on my Sue, yes
I'm not saying 12.4 is the best estimate for it, I'm basically just saying it's not completely unreasonable either
Birds are robots
just gonna drop this here
Just gonna drop this here too

Is Dan Folkes’ missing cartilage or is he just a short king?
Missing cartilage
Sheesh sue has some big molariform teeth
Nah you gotta add cope fr fr
Bro is literally the same size
Nah, Scotty is 10.4 tonnes, cope is 10.8 according to randomdinos and probably like .5 meters longer idk though lol
😭 .5m is like nothing on an animal the size of rex and even then, that’s based off femur allometry which isn’t an exact science
10.4 and 10.8 is very negligable yeah. A single good meal is making Scotty as big as Cope
Well it's better than a 12.4 tonne 13.3 meter animal (which technically may be possible but I doubt it) so I'm just going with 10.8 tonnes because it's femur is super wide, maybe even up to 11 tonnes if you literally just scale up a 10.4 tonne Scotty by 7%
One could say, you have to cope with Falcon not adding Cope
bro you're literally a dentary giga fan
Kidding, dentary giga is a cooler specimen because it has lore
nuh uh
What's worse, dentary giga or 12.4 tonne 13 meter cope
Random came out swinging and then took it back, I can’t believe this
swung and then unswung
Dentary giga needs a name smh
Cope. Dentary giga is isometrically scaled, 13 meter cope is just a bruh moment
It has one, MUCPv-95
Another beautiful day not caring about single bone specimens
Even after watching that video I still don't get how they got a 13 meter cope, largest it should be is around 11 tonnes

why does my chat keep going away
Anyways, you guys see that new cope specimen?
Its an absolute beauty
a single femur
While only being 10% complete, we do have much to go off, much more than the toe bone specimen that maybe have been something else
While its a single femur, that same logic can be applied to the dentary
I feel the same way about the dentary
I feel a bit more for the 10% complete specimen compared to the jaw fragment, makes somewhat sense
While we can possibly say its larger then scotty using femur size alone, not much material came from it 😦
I knew it wouldn't be enough, any Rex specimen needs to be at least 50%+ complete for anyone to acutally take seriously
Every now and then I come in here and ask people “show me ur fav skeletals!” For arts refs and it’s that time of the year again 
My new favorite skeletal is a femur, largest rex femur though
Well there is other stuff, it's just not measured
Either Cope or Bertha are going to be the largest now, Scotty definitely got de-throned
And rex gets the title of being the largest theropod known, again
i mean doesn't rex have ALOT more fossil records compared to most other dinos, which id imagine is the reason why
Some fossils aren't large enough for people to care, or complete
How do you know either of those are bigger than Scotty? We have a single femur measurement for Cope and nothing for Bertha outside of a tweet, idk how you can make such claims
The sheet on the femur size gives a pretty good idea
The fact that there may be 4 rex specimens that may reach 10+ tonnes indicates such sizes aren't as rare as we thought
I mean, it gives you a pretty good idea for the femur and a very generalized idea for the weight of the owner, but you can’t get anything concrete
having seen pictures of Bertha's toes in mounting (😳), nothing about it indicates being on the larger size of Tyrannosaurus specimens, let alone bigger than Scotty. Cope's slightly better off, and indeed about as reliable as dentary Giga
Oh cool, thanks random
Could just be the picture
for sure, I would not use toe scaling to estimate anything anyway lol
i mean thats a maybe vs a yes 100%, tho i wouldn't be surprised if it was more common in large theropods like rex seeing how often the info changes
Sue looks more robust than Scotty in most images you find, turns out, when looking at a gdi of both of them you can see the difference
Well to be fair, Scotty’s mount is actually pretty thin (dorsal) for some reason which would explain how it looks “thinner”
So of course there is indeed a possibility of a smaller than Scotty Rex, I have to admit we don't have much to go off, or, this really could be a big specimen
wasn't there a few estimates for a 10 ton trike( as in triceratops) right?, just wanting to check since i haven't seen or heard much about it
Yes there was
''Triceratops albertensis'' is definitely over 9 tonnes, estimates will vary because no one can agree on Triceratops' proportions these days
it gets mixed between 10-12
Anyways, guess we will wait and see if we have new record breakers
I doubt that people will keep believing we haven't found a larger specimen than Scotty
oh well thats a new name to me, so i'm assuming its a more recently found out one(|| or the off chance is a funny haha knowing how dense i can be||)
Wait
If Tyrannosaurus does actually get the 11-12 ton estimate, would that make it the largest theropod again considering that the only "tie" it had was the dentary?
It always has been the heaviest estimated theropod.
It's very old, but for whatever reason everyone forgot about it
Probably for the best considering the state of preservation of the skull. It's pretty garbage
The mass estimates between Giganotosaurus and Tyrannosaurus makes me think they both can get as large as each other, unless you straight up only use "Scotty" or "Sue".
largest specimen of a taxon try not to be garbage challenge (IMPOSSIBLE)
Though we need more specimens from the former.
oh that explains it then, noted
Perhaps. This could intuitively be applied to a few other Theropods as well.
Yep
And it inherently subjects itself to uncertainty
I suppose you can pull an Occam’s Razor through it.
We all know T. Rex was big but could a Robert Wadlow T. Rex exist? One so big that it made ones the size of Scotty or Se look small?
*Sue
Are we allowed to send links to YouTube here? I only ask because I came across a vid today which pretty much stated that the Rex was a better swimmer than spino but also may have herded prey toward water to take down more easily
How to fix lag in path of titans?
People out here actually taking a Vivden clickbait video seriously smh
my kingdom to live in the timeline that doesnt have to deal with "weird T.Rex fanfic" papers
do you guys prefer spike-backed theropod (left) or smooth-backed theropod (right)?
Smooth backed
Both
spike-backed theropod
Smooth
Smooth
Smooth Carcharodontosaurus.
Smooth tbh
Smooth, except if it has iguana-like spikes
Feathered backs 
Smooth
Wait, Concavenator had feathers, no?
Why would it?
Some weird structures on its ulna were suggested to be quill knobs
Yeah, it had feathers
Wonder if its relatives had feathers or quills or something like that too.
Scipionyx did 🤷♂️
Oh right! I forgot!
Scales be damned, protofeathers are everywhere
. At least when you’re a little guy
I think those two would be inferred, Beipiaosaurus does though I think, and that would be a young specimen, so certainly a larger fella in life.
Mhm
Smooth
Iirc it didn’t have feathers but it had quills, almost like the defense conc we see in game,
Quills are a type of feathering.
Hold on so what’s the deal with E.D Rex? Is it bigger than Scotty?
Yes but an animal can possess quills but not feathers, as in the case with Concavenator
No, no, I mean quills are literally feathers, they are classified as a type of feathering
We don't actually know if Concavenator had quills or feathers as quill knobs mean pennaceous feathers in modern birds, but due to their strange morphology, no-one is 100% sure
Thought the most accepted theory was that it did. Like on the arms
There is no most accepted theory 😎
😀
Unsolvable mystery reconstruct them as either simple quills, or as the quill shaft of a fully formed feather
Quills also don't necessarily equate to feather either. Psittaco's quills might not be feathers, mammal quills certainly aren't feathers. Filamentary structures to be as broad as possible.
More recently the only thing I've heard more definitively classified as feathers is pterosaur pycnofibers, which is a big can of worms opened
Been opened for a while I think 🤔
I like both equally as long as the rest of the design is good
not for I wouldn't say, only in the past couple years
There wasn’t much to be discussed, the implications were a one and done deal
In Concavenator's case quills do mean feathers, as it's specifically wing feathers that leave quill knobs on the bone. But the issue is the identity of the quill knobs is disputed
So, how deep would that implication go then assuming that is the case? Would that imply Carchardontosaurids independently evolved wings?
Yeah, since Allosaurus has scales preserved around the armpit area, it would have to be a pretty novel development
Both interpretations are pretty novel, tbh. The marks don't exactly match those made by quill knobs but they don't match anything else either
For now I think Cuesta had settled the discussion a bit, or has the most recent published paper on it.
has anyone seen the fact the professionals discovered the andrewsarchus mod... more specifically the Hippo morph
Yeah, and they’re way too hard on it imo. Like I get the issues but more than the hippo morph exist.
Tyler Greenfield also blocking one of my friends for purely pointing out it’s a fragmentary taxa in a video game is pretty unprofessional
Where?
._.
Imo, it's a perfectly fine event to happen. People are taking the Andrewsarchus mod as fact, every single morph (especially the chubby one)
Its a bit too piggy, but its a neat mod, a lot of personality.
its funnier cause you know they dont play the game so think its official, but its literally a skull so sorry that mod makers had fun with one of the morphs being more hippo ish
"A lot of personality" doesn't make up for the misinformation imo 🤷♂️ but that's my hot take of the day
I do admit it kinda shows why accuracy is important
“Oh it’s a video game it doesn’t matter” exhibit A
Ime I feel like outside people who dont play the game treat eveything as official.
besides it used to be a whippomorph so the hippo morph could be like a fun nod to it
How is it misinformation? Its not like the mod reads "100% PALEOACCURATE ANDREW, 1000% REAL"
W take
Doesn't matter because people don't read that it's a mod, the reason the professionals took note of the mod is because people are going "Omg, Andrewsarchus looks like this now?? Crazy!"
Thats a masses being stupid issue and not a misinformation problem.
granted playing POT reeally shows who knows anything or not
The fact that the hippo morph exists suggests that the base model of Andrew in that mod isn't very good either. You can't make morphs that are completely different in terms of proportions and anatomy from the base
well, you can, but they will animate pretty terribly
my opinion as someone who hasnt really touched it is that immense speculation was used since we have the top jaw
I heard that they plan to release an accurate Andrew mod but I can’t confirm that atm. I’m asking. I heard that but wanna clarify.
in my opinion the entelodont morphs probably accuracte..cause isnt current consensus that its at least outside Entelodonts
Yeah, but Tbf in a study very recently they looked at andrew’s taxonomy properly for the first time, and it was just outside of entelodontids. So it probably looked like um too.
. . . Why are the professionals getting hurt over someone's interpretation of Andrewsarchus when we only have the upper skull?
I can understand the concern cause of how it was received but blocking people for not understanding y it’s a big deal’s uncalled for
I mean, it's an interpretation, not factual.
I imagine that's why there's concern. "Hey that's my work you're meddling with"
You'd hope someone making an animal based on a skull would at least follow the skull of said animal
i think the issue is they dont know its a Mod and not official
That aspect isn't the most favorable look for PoT anyway
That is true. And I can understand the concern too.
. . . That aside, why hasn't anyone tell them that it's a mod for a game?
people are its the question of caring
It’s also the fact that people are quick to take seriously things about a taxa they don’t understand
it doesn't help that Andrew is already impossible to understand anatomically
Evidently that's not exactly the case if it's getting torn to shreds
i think the issue is the body being based off close relatives when we could get a curve ball and andrew isnt like any of them
After some rebuttal in the mod channel I got the Andrew attack-speed sub model without the hair in the way https://media.discordapp.net/attachments/538828511717097472/1147988301085687838/20230903_141512.png
and any of the detail of the model for that matter
I like how people went from shrinkwrapping everything to wanting eveything to be obese.
I think it was on here that someone was complaining about PT rex because it wasn't fat enough
when its like..conservative
Gravity
That's not what I mean, but I see
They really made Everest out of an ant hill.
These foolhardy gents clearly didn’t see the stocky variant
sigh
"Mindlessly comment"
Just a twitter moment
sorry X-🤓
Yeah . . . Twitter/X, is just a very weird place.
Twitter/X lol
Happily have a source right here to dissect if any of the people that criticize the Andrewsarchus wanna confirm what they’re saying. It looks fine to me.
Generally baffling how people are annoyed by this
I mean it may contribute to misinformation a tiny bit, but its not like theres much to go off on Andrew anyway
I think whoever said it’s just people being dumb might be right
uhh any new...decently big theropod news
Not that I'm aware of.
Maybe not new, I just recently heard there was a swath of debate on the exact details of I. challengeri’s cranial kinesis implications. Wish that whole topic could be elaborated on by someone knowledgeable
The “Pelican” part itself
ahh
Some suggesting there was still the distinct and equally likely possibility it was more analogous to the snake-ish depictions or “hypo-spino”
That was my initial thoughts, just reviewing the information
Yeah no the hypo spino things just straight up made up
pretty sure the hypo mouth is meant to be gentically modified anyways..from what i remembr about TIs confusing and limited lore
I think I read somewhere this depiction in particular got the support of someone knowledgeable on the topic
That’s more accurate yes
was..the official reason TI renamed the utah to something else to avoid paleo bs and just say genetic tampering or something..like how PC did with Nova
Iirc some people misinterpreted the study as a hypo-type jaws and that gained some traction for a day or two before it was pointed out it was more like a snake like above
Yeah they couldn’t ignore the cries that it obviously wasn’t Utah anymore
yea cause i think it..was just a big deinonychus or something right..?
So it is more like a snake?
Like this
What is this chat for?
It’s less that and more that they’re pretending they weren’t ripping off Jurassic Park lol
It’s totally Utahraptor guys lmao
is..TIs utah head up to date or literally just a JP head..
The latter
Thank the stars. This is how I was representing it, but my confidence waned a teensy bit
i need Sauropelta in more media..best Nodosaur
And finally hopefully there’s a goofy answer for this, I remember there being a tweet from someone elaborating on which Spinosaurids they think the condition appeared in?
This looks cool
palaeontology
is this a bit too fat for macrauchenia
I know nothing about that
this is a good lad, btw. i like this lad.
Looks fine to me
best dinosaur name goes to Animantarx
actually i think most Ankylosaurians have among the best names..
aight, nice
confirmed acro or....eh 110 is the very end of Acros existence..
Wasn't there possibly Korean acro's?
i think its based off teeth
i only recall that stupid koreaceratops documentary using acro exactly
there's some teeth referred to acro
Sounds right to me
said Paluxy so safe to assume Acro
PDF | A large tooth of theropod dinosaur that was recovered from the Hasandong Formation (Lower Cretaceous; Aptian-Albian) in Daedo island, Hadong... | Find, read and cite all the research you need on ResearchGate
Sounds sus
what are the chances of a acro sister taxa
it is yun so true but even then it's cf. acrocanthosaurus sp. so it isn't intended to be acrocanthosaurus just a similar taxon
Hilariously enough it might not be entirely stupid given acro is the only known American carchar and it had to get there somehow. Don’t read too deep into this tho.
and yun didn't even describe the cf. acrocanthosaurus teeth
NA is full of asian exclusives like Deinocherids and therizinosaurs...though i think falcarius implies a american origin too
the paper just posits that the cf. acro teeth, wakinosaurus, and prodeinodon kwangshiensis teeth as well as some other large carch teeth from east asia belonged to various taxa ancestral or related to taxa ancestral to acrocanthosaurus that emigrated to North America
Paraxeni is also questionable
that's being generous paxaneri's utter crap it's a bad example
isnt..rex debated as a asian immigrant
That atrociraptor looking kinda off
Rex was yes
yea cause Zhucheng and tarbo are asian...
ye it's pretty much just circumstantial evidence but it makes sense
...just like today america had no original ideas, are there any NA originals..
me when faunal exchanges occur
Just like acro fr
Horses were exclusive to NA until the ice age
...im ashamed cause i learned horse evolution cause my moms a horse person
Dogs also come from North America
So do nukes
Can you bloody not?
wait are we talking domestication or canids as a family
Canids originated in America, and the first domesticated dog was from Asia iirc (although I could be thinking of the first dog breeds created by selective breeding)
there's a theory that the disapperance of horses in NA at the end of the ice age had something to do with the apperance of bison on the continent
Nah. They coexisted for a healthy amount of time.
Hey don't American flag react me, that wasn't supposed to be a positive thing, I'm opposed to nuclear weapons
Ceratopsids are an American original
Huh, I actually wasn't aware of that
There’s only a single Asian species
Are there any north American spinosaururs?
Yesn't, if we assume the paper was right in their identification
North America was largely isolated for most of spinosaur evolution so probably not.
They first evolved in Europe then moved south in two different directions
it's not that horses and bison couldn't coexist but more that bison coming to dominate the large herbivore niche may have effected how NA fauna including horses were effected by the ice age ending
since bison only even entered NA in the last 200k years
oh yea aquilops
I mean yeah but horses were also some of the last living megafauna that went extinct alongside mammoths
Anyone have some real nice skulls? Preferably blocky ones, using them fro a dragon ref
still's possible
i don't know the nitty gritty of it I just heard it from eric scott
i think he published a paper on it or something
Sinoceratops. Note I said ceratopsids and not ceratopsians.
am i the only one a tad miffed that every kaiju related name isnt from japan..kaijutitans SA,Gojirasaurus from new mexico
Gojirasaurus ain’t a thing
i will fight
it's an undiagnostic coelophysoid
and also a chimera
still gonna call it gojirasaurus
i too love coelophysoidea indet
syntarsus is valid
Yes and no
wasnt it found out it could be renamed syntarsus again..
Basically, you got three species thatre within some wierd coelophysis, mepagnosaurus, and the Kayenta one dituation
kayentawhatever still goes by syntarsus
kayentakatae or something...i just know its fun to say
i think kayentakate is effectively nameless technically because normally it'd just follow where megapnosaurus is in but since it's distinct it's stuck with syntarsus
Coelophysis bauri is valid but the other 2 need to be properly distinguished and put in separate genera that aren’t screwed up
at least the Dilo trio is easy..Dilo has big crests, sino has smaller crests and draco may or may not have them
Sinosaurus is hella broken
sino's kinda odd though with it's species
wait did they name a sino species with that skull?
Risking my life by using Discord rn, but what? I thought Syntarsus was renamed because a bug already had that name, hence “Big dead lizard”
It contains 3 very different animals in it. A dilo-like animal, a monolophosaurus-tetaneuran-like animal, and a coelophysid of some kind
as per that skull paper this year i think s. triassicus s. sinensis and shuangbaisaurus are all valid
shuangbai is still its own species?
that hypsilophodon looking kinda off guys
and then there's the "sinosaurus" vertebra that was actually a prosauropod and sinosaurus shwanesis by proxy also being a prosauropod
that..isnt Turano
They’re like that cause GSP in his infinite wisdom lumped them all and nobody’s been willing to touch it since
what was the heaviest ground sloth?
Table really just ignoring my valid question while my life is on the line
you're correct so the type species rhodiensis was renamed megapnosaurus. problem being kayentakaetewhatsit doesn't clade with rhodiensis so it can't be megapnosaurus
i think..the bugs name changed..
you can't name after preexisting nomen dubium anyways
Eremotherium
what🤞😭
yea syntarsus is now a junior synonym for the beetle
Syntarsus was described with the species s. rhodesiensis. Later another species would be described from arizona, s. kayentakatae. Then some entomologist realized a beetle was already named syntarsus, so he took it upon himself to give it the dumbass name "Megapnosaurus" (big dead lizard) despite the fact you're supposed to let the person who initially named the taxon rename it. So s. rhodesiensis and s. kayentakate became megapnosaurus rhodesiensis and m. kayentakate.
However, megapnosaurus has been suggested to be a junior synonym of coelophysis, in which case the two would be species of coelophysis. More recently, kayentakate was found to be distinct from both coelophysis and megapnosaurus, so it's stuck being called syntarsus kayentakate (the original name) for the time being in the abscence of an actual generic name

yesn't
jwe carch
WDRA dilo
oh there's also syntarsus mexicanum which lacks both a diagnosis and a type specimen

how concret is the alleged 30 foot or so Sillosuchus
yea conflicting info cause some say it was misidentified as saurosuchus
is there anything else in literature about it cause this is all i could find
im just checking wikipedia..
wikipedia cites those two
everything seems pretty consistent then
6 paper references
three of em predate the saurosuchus vert being reassigned and the other one is in reference to a skeletal reconstruction being unveiled
I find giant Sillosuchus pretty sus
it's a single incomplete centrum, is there really no other animal it could belong to besides a 30x larger version of a shuvosaurid?
what else could it be..
huh justin made a skeletal neat
that thing is like 4 tons
3 if your generous
there must be some kind of neck allometry going on, surely a 10 m animal does not have the same proportions of a 4 m one
Plateosaurus is smaller than this in length and height and weighs 4 t
all i know is even by pseudosuchian standards, Shuvosaurs were weirdos
"giant shuvosaurids lived with saurosuchus"
larramendi pseudosuchia book when
i would buy the heck out of that
i dont care if like half of it is BS i just want to see the art
i have..the other 2 right here beside my bed
would it be safe to assume the giant Aardonyx is more likely..i know it more then likley wouldnt be Aardonyx thats just what i remember being the commonly used comparison
why is david peters the only person who makes poposauroid skeletals
David Peters moment
if he has no competition he must be right..
can't be aardonyx anyways since aardonyx is upper elliot
i just know its always using Aardonyx as a base for like depictions
it was compared favorably to aardonyx in the abstract iirc
it had 1.9(?)x the linear dimensions of aardonyx or something like that
aardonyx is best South African sauropodomorph..
there's like a half dozen of em
South africa was wild from like the Permian to the mid Jurassic
rip 12t ledumahadi
I don’t think South Africa has ever stopped being wild
man got his mass slashed to like a third of the initial estimate
larramendi's book
oh yea cause it was..2018?
idk it was all in the past five years at least
Maastrichtian South Africa 😎 (doesn’t exist)
maastrichtian not morocco
what is the biggest sauropodomorph...Yunnano?
I mean it probably did
(all the wacky stuff that was probably there hasn’t fossilised 😀😀😀 😔)
Don’t forget about that single Pteranodontid and Elasmosaur found in Angola🗣️
and the teeth and stuff from egypt
pteranodontidae..gross
Oh actually hold on it’s not a Pteranodontid
Pterandontids gotta be some of the worse pterosaurs
Dear oh my, what the hell is this clade, Aponyctosauria?
ghost lineage and terrible phylogeny..
Pteranodontidae at large or?
anyways largest prosauropod looks to be some stuff referred to yunnano
Does Maastrichtian Antartica exist
but actual largest will probably highland biped when it gets described
imperobator
Yes actually
Wellll, just the Vega Islands, but beggars can’t be choosers can they
imperobator is maastrichtian
There’s a whole lot more from there, but yeah
its the first one off the top of my head
Wait Imperobator is from Antartica?
Why was I thinking it was from Greenland or something 💀
they had antarctica in PHP 2
Elasmarian representation, first time ever it feels like
uhh no dryo was in WDRA
So its the second non avian theropod found there after Cryo?
is dryosaurus a elasmarian..or more basal..
elasmaria's cretaceous
Basal I guess
oh ok Dryos family is within Iguanodontia
there's leaellynasaura if you want elasmarian rep
When did that fella appear?
..early creteacous?
albian yeah
118-110 mya
No in media 😭
your next step is to figure anything about the internal relations of elasmaria
and technically a megaraptoran
totally not Australovenator
allosaurus robustus
Within Ornithopoda itself?
within elasmaria
did anyone see..PKs Muttaburra reveal
yup
i thought it looked nice
It always looks nice
it actually looks like a Rhabhadontomorph
I’m hotly anticipating their marine animals. Maybe the first good Mosasaurus depiction? (Unless PT beats them to it)
yea i dont think PK will have marine for a while
although update 9 gives us Mutta and 2 more animals
2 more? Who else is coming 
not revealed yet
Any theories as to what it is?
not that ive seen..beside still waiting for update 8 and roadrunner Velo
But that’s separate of the other two right?
To be expected from PK
All of their stuff is awesome
yes velo is coming update 8 and update 9 is 3 including mutta
Does PK plan to do any Spinosaurs we know of? Or is their future roster a mystery
i think spino is one of their first ones planned..bary i think is still on the EA roster
there is..spino concept art.. but im not sure if its still valid
Really wanna see something like Austroraptor or Altispinax from PK
altispinax is the wild card since we have like 3 bones
Concavenator instead 🗣️
Yeah but Altispinax has the cooler name so we let it slide
wouldnt be surprised conc gets in for spanish rep
Altispinax as an alt skin of Concavenator would be nice
it certainly differs less from conc than tarbo from rex
alti is great value conc
it's also astronomically less complete than rex and tarbo so there's not really much room for distinguishing traits
Isnt Alti a bit bigger than Conc? Or the other way round?
I hope as per my usual stance they have some good lips on those Spinosaurids, but considering they even went with partial covering for Tyrannosaurus, my hope is strained
I mean, how can Tyrannosaurus differ from Tyrannosaurus
I forgor
size doesnt matter in PK cuase they managed to make species different sizes, best example is the Camara
I think alti's smaller?
I’d wager three dorsal vertebrae are in fact not larger than an entire skeleton
yeah 5.53m vs conc's 5.8m
let alone a sample size big enough for max sizes
ignore the weight
Yeah so that could actually work for a skin for Conc if PK ever comes around to making Conc
Would it be necessary though?
concs a unique enough animal it has a shot
I have to ask though, how possible is it for Tarbosaurus to be a species of Tyrannosaurus?
Yes
Alti supremacy!
I think that’s the prevailing theory, new skull or something?
bro always used Spinax on FF
plus you could c. altispinax or c. dunkeri or c. becklespinax because of much of a mess alti's name was
Didn’t becklepspinax get absolutely obliterated
pretty sure tarbos distinct enough from rex
yeah
Even this mysterious skull which I allude too
You can't lump Tarbo into Tyrannosaurus without also lumping Zhuchengtyrannus. But Zhucheng is early Campanian which is insane
Really? why is that?
huh i thought it was tail end of campanian but I've never read into it
Isn’t there also another undescribed tyrannosaurid at Zhucheng. Dont know if this question is relevant
yeah
This is how I understood their morphological differences, but apparently there’s a specimen with more synamorphies with T. rex?
my biggest pet peeve are people who call Zhucheng Z-rex cause they cant be bothered to learn to spell
it's also a dentary and maxilla iirc
Is it around the same size as Tarbo and Zhucheng?
Zhucheng being Early Campanian means you had genus Tyrannosaurus before the appearance of albertosaurines
zhu's pretty much tarbo sized if you assume suecheng is zhucheng
whats the possibility of a 4th tyrannosaurine
Zhucheng didn’t continue into the Maast?
there's tons of unnamed/undescribed tyrannosaurid taxa in asia
I understand that but why is Zhuchentyrannus involved if Tarbosaurus is lumped in Tyrannosaurus? is it because it is more closely related to those two?
Zhucheng and tarbo are tyrannosaurini with rex
so did hongtuya get redated?
Yes, half of all phylogenies have Zhucheng as sister to T.rex, the other half have it sister to Tarbosaurus or basal to tarb + rex clade
Here I found it
Ah, thank you for the clarification
looking at zhu's description it's locale isn't any earlier than 73.5 ma but saying it's early campanian seems like a stretch
unless something new came out there's over 10 ma of the campanian before then
Zhucheng has like..the coolest ecosystem..
giant hadrosaur and giant centrosaurine
Wait were Tarbo and Zhucheng around at the same time?
Nuh huh, Lopez de Bertodano is cooler
uhh i think tarbo was actually recently redated to around 66..cause nemegt was put to 66 a while ago..
that's the minimum age contraint
Awe so no more 3 giant tyrannosaurids running around Asia at the same time
3?
initial deposition would've been earlier
The undescribed one at Zhucheng alone with Zhu and Tarb
I doubt Zhuchengtyrannus was ever contemporary with Tarbosaurus
for tarbo and zhucheng to be contemporary nemegt would have to had to last the entirety of the maastrichtian and a million years into the campanian unless it got redated which i don't know and it would be lovely if someone told me
Wait yeah just realised Zhu was knocking about in Asia at the same time as Daspleto
Maybe a little bit later than it
something did, but I don't feel like searching KOI for the redating rn
Within a couple million years of horneri
So what’s the story, Xingezhuang is older than previously dated? Or is just Nemegt being redated
y'know if i was in koi i could search for it myself wink wink
sike i did search it
Clapped
well it was worth a shot
Sheesh, Zhuchentyrannus got sent way back
What the hell sorry Random 💀
just accidentally slipped and called lmao
I don't know why you aren't in KOI anyway, I am going to send you there
i may be stupid but whats KOI
Is KOI an elite group of paleo discordists
paleo secret service
And Nemegt, now dated at 66mya?
Minimum 66, it likely starts much eatlier
nemegt got it's minimum age redated to 66 ma so deposition ended 66 Ma. it could've actually formed earlier
Mkay
Is there a possibility tyrannosauroids were running around asia when Zhu-Tarb were around?
alectrosaurus maybe iren dabasu has weird dating
alectro is problematic
although i think it's before nemegt at least
alectro itself is fine it just have like 234324 things referred to it with no overalpping elements
isnt the holotype not fully described or something
asian small tyrannosaurs being screwy
Alioramini are just delicious
i..dont like that sentence
Alioramini just stupid
no its not theyre distinct
Why give up being obese and having big jaw nom nom
yeah alectro got a redescription back in 89
being obese doesnt help if your catching faster prey
alectro's crazy fast
At least they got a tribe instead of their own subfamily
alectro's faster than every tyrannosauroid that isn't a juvenile albertosaurine
Hey didn’t someone do Larremendi’s formula and Qianzhousaurus turned out kind of an average speed compared to what we’d expect from it?
That was a low blow no need for Alioramini to rub it in
What on the earth is Deinodon
tooth
Dubious?
its a damn tooth taxa
Means it’s super reliable 💯
its also from the 1800s
Dont know what I was expecting 💀
i miss Shanshanosaurus
Im assuming Aublysodon is same as Deinodon?
another 1800s tooth taxa
Are these both from Judith River?
Yup 😎
Gorgosaurus/Daspletosaurus cf., there all cleaned up 🧹
i think Deinodon is debated juvie dasp
Trust me bro 
Deinodon is like, everything
Perks of being a tooth taxon, teeth can look the same across various species across continental distances
Not even going to ask about Raptorex i already know about that little hellpsawn
uhh 1800s nomenclature
Some of these aren’t even Tyrannosaurs
yea? pachycephalosaurus was troodon at some point and dasp was ornithomimus
Maybe that’s what this list is on about. Truly the best genus of all time
Who let them do this
mother nature being her self
Nanotyrannus lancensis 💯
technically exists cause baby rexes are their own little gremlins
Scipionyx, the superior gremlin
baby trike a literal imp
Don't insult these creatures
Now my question is what is larger, horridus or porosus?
its like the blobfish..its fugly cute
Would Giganotosaurinis have went through similar growth spurts as Tyrannosaurus did?
I think giga and the like grew faster and reached adult sizes at a young age.
The youngins may have that comparative lengthy proportions to an extent
Ive just realised someone needs to edit the Alti wiki page
Bro isn’t even registered as a member of Carchardontosauridae
Usually when they do it it’s because a taxon has a shaky cladistic record, but they straight up just left bro out like that
Altispinax looks a lot like conc, guess that makes sense
No. Given some interesting findings, it seems carcharodontosaurids grew gradually and lived for several decades, while tyrannosaurus and its close relatives grew rapidly and got old in their late 20s.
It seems thats not always the case with every Tyrannosaurid or Carcharadontosaurid: Acrocanthosaurus seems to mature similarly to Tyrannosaurus, while Tarbosaurus grows relatively slowly compared to its closest relative.
Fellas? I hear there's new wendiceratops material? Any info on that?
Thank you
So I managed to gather the issues with giant Gigantopithecus. Most notably, the 2.7 meter height estimate just straight up does not have a scientific source? It seems to largely be parroted off of Wikipedia despite the fact that, in my searching, I could not find the origin of Wikipedia excerpt anywhere. Wikipedia left no source on it. The next best thing provided based on gorillas is suggesting that Gigantopithecus femur length was 20-25% larger than a gorilla’s, which is still perfectly valid and does not yield a 2.7 meter tall ape. There have also been people that have reconstructed the jaw remains with related ape proportions, like this image here (orangutan), and you can see that there is no way in hell this ape is getting to 2.7 meters unless it’s porportions are taller and thinner, or like I said, more human. Instead you get an ape slightly over 2 meters at full height, albeit it’s still the largest ape by far. Still a 200+ kg giant. https://media.discordapp.net/attachments/475022555032453140/1148053738796351528/image.png
@main peak
yeah that's what I am suggesting
Is spinosaurus still considered the largest theropod ?
Weight no height I believe so
Cause it says in length and weight it’s the biggest but not height that’s probably giga Carolinii
I saw this but don’t know how accurate it is
How heavy was Maip?
3060kg
that chart's pretty bad
Oh does anyone have a more accurate one ?
https://docs.google.com/spreadsheets/d/1GVpHchzogtjkTqQrP7PFM2BAWMGHYHABD-Xnk_6KPj0/edit
this sheets pretty decent
Sheet1
Species Name,Length,Weight,Specimen,Red = not updated/unreliable
Tyrannosaurus rex,12.4m,10.45 tonnes,RSM P2523.8
Giganotosaurus carolinii,12.7 - 13.5 m,8.20 - 10.10 tonnes,MMCh-Pv-95
Deinocheirus mirificus,11.77m,8.39 tonnes,MPC-D 100 & 127
Mapusaurus rosae,12 - 12.3m,6.90 - 8.20 tonnes,...
Thanks !
Also is it still disputed if torosaurus is an adult trike or another species ?
nah, they're 100% different animals. there's too much stuff that doesn't line up when treating triceratops as a juvenile torosaurus
dracorex is a juvenile pachy, yeah
stygi's a lil bit more complicated iirc?
stygi's probably pachycephalosaurus spinifer with dracorex being an ontogenetic stage (of p. spinifer)
So stygi is like a subspecies ?
It's a separate proper species from Pachycephalosaurus wyomingensis (tradional pachy), like how lions and leopards are two separate species within the genus Panthera. With Dracorex being the same thing as Pachycephalosaurus spinifer (Stygimoloch).
Ahhh Gotcha , Do you know any good dinosaur YouTubers that posts videos on new Dino discoveries just so I can stay updated on paleo stuff
raptor chatter's great and so is the skeleton crew (though they don't do much news) and ben g thomas is pretty good as well
your dinosaurs are wrong too
Thanks !
Very interesting, though to me that skeletal still looks a fair bit taller than the one paleo-art piece I've seen floating around 😛 Would you happen to have a link to any of the Orangutan related studies? I have had a hard time finding good info on Giganto because of all the rather poor info out there.
What do you mean by orangutan studies?
the ape of all time
The ones you mentioned that reconstructed the jaw remains "with related ape proportions"
Its like the 5th largest one
Spino was likely the longest, but when referring to the "largest" it usually referring to weight. Rex is the largest.
is rex the tallest as well?
Probably depends if you include the sail or not, not sure tbh
Theri is iirc?
https://www.sciencedirect.com/science/article/abs/pii/0047248479901118 if ur referring to the orangutan reconstruction then it’s not something in any article, that’s just as an example put together that shows it cause of how you can’t conceivably make a 2.7 ape look correct with the given skull material measurements
Also here’s the largest theropods for those asking (carchar is likely to change soon tmk but that’s about it)
- Tyrannosaurus (12m, 10 tons)
- Giganotosaurus (13m, 9 tons)
- Deinocheirus (12m, 8.5 tons)
4+5. Spinosaurus (14m, 7.5 tons), Tyrannotitan (12m, 7.5 tons)
6+7. Carcharodontosaurus & Mapusaurus (12m, 7 tons) - Saurophagonax (13m, 6.5 tons)
9, 10, 11, + 12. Acrocanthosaurus (12m, 5.5 tons), Suchomimus (12m, 5.5 tons), Therizinosaurus (9m, 5.5 tons), Tarbosaurus (11m, 5.5 tons)
Why does this chart have S.aeg at 3.1 tons
It’s the whole “this one specimen may not be spino” mess
Great, thank you! We need more official studies on Giganto...
damn didnt know deinocherius was that big
Yeah it’s a unit
yeah the two spinosaurus in that chart confused me
bruh just found out about a trex called E.d cope which would be bigger than scotty
Could
would be pretty terrifying finding a trex bigger than scotty though
of course its named cope
they just found out about it themselves
that's holotype spino
I assume from the Vivden video thats suddenly eating everyone's algorithm. Best not to take anything he says seriously
You mean why you shouldn't take paleontological isnight from the guy whose every video is about "the biggest" size contests and power scaling? The guy who takes the "neuron count" intelligent Rex garbage seriously?
ok the only one there is the rex neuron one that might be a bit much but last i checked "whos bigger" contests and Who would win fights are nothing new...besides i watched the rex v giga one and he wasnt biased
besides he admits his mistake with the neuron thing in the comment's..
I'm really not sure how else to explain that someone who's interest in prehistoric animals begins and ends with "which was biggest and strongest" isn't worth listening to. They'll take any paper that ups something's percieved "capabilities" as fact and run with it no matter how dubious the source, so long as it makes it sound cooler.
so i must not like dinosaurs then cause i like those contests as long as theres no bias and its explained how each party could win simply cause i like it
pro tip: "someone whose interest in prehistoric animals begins and ends with Which Was The Strongest" and "someone who's interested in prehistoric animals and likes Who Would Win discussions" aren't the same
autism dictates it involves dinosaurs so i have to see it
Thanks Mozar thats what I mean, Im not telling you what you can and cant enjoy, Red
at least, I dont mean to
Yeah I saw the Vivden video but didn’t know how refutable that guy is
i mean..the rex v giga video seemed like one of the better ones cause it isnt biased and he states that situation matters or something like who would hit first.. i just know he probably has the only decent video on Bruhathkayosaurus
what is..Megalanias current length estimate..still 23ish feet?
20 ft, 6 meters
Intraspecific body size variation, so sure I guess
god if Komodo tail whacks are compared to sledgehammers imagine how strong a full powered Megs tail smack would be..
Very painful
just folds your spine
What epoch is it known from
The one right now
👍
thissun
Only the Holocene?
i think that it was in decline due to the on going megafaunal extinction in Australia then a certain ape appeared with their sticks and fire and probably pushed them over the edge
Probably not idk
pleistocene..to Holo? cause i think current extinction date is roughly 40,000
Makes sense. Pleistocene is pretty rad 😎
Mammoths survived into the Holocene, Wooly specifically
Hey paleo chat, how many dinosaur species exist as of today
1300 genera roughly
I wonder how reliable any given number would be, considering all those nomen dubiums and waste basket taxon n stuff
That feels way lower then I expected
cause genera isnt species cause some genera have multiple species and im not even including birds
I mean you have got every bird extant and extinct. You have got a ton of undescribed dinosaur material which could lead to more genus’s and then theres around 1300 described non avian genus’s. Its hard to pinpoint the exact number
13-20 ft
Any info floating around about what kind of biome/environment the Chorrillo Formation would've been?
Warm temperate, seasonally humid with a well watered floodplain. Lots of aquatic plants have been found, including water lillies. Forests were a mix of conifers and angiosperms
thx
My understanding is that it was a coastal region that was subject to seasonally high humidity. It also seems to have had a delta system running throughout it.
Basically the same as what gbones said I guess 
tysm, was having a tough time interpreting the papers
I mean, have you seen them in game rn?
It’s true, I was there
I literally can’t explain because of the damn censor bot. It sounds like a not so nice term for Pakistani people in Europe
Lets just say people were calling the ‘pachy’ part a racist word
Speaking of environments though, do we have any modern examples of a lacustrine rift-basin?
I think the african rift valley and baikal both have one
Yeah both are good examples. The great rift valley in Africa has tons of rift lakes, very cool place
I’d been reading some literature about the Romauldo Formation, the terminology popped so I was curious as to the in life appearance of the environment
Like a series of large valleys, some filled with water, some just holding a bit of water (perhaps as alkaline lakes) and some dry/filled with vegetation. Rift valleys are really cool because it's literal plate tectonics happening before your eyes
There's a marine element too iirc so a good modern proxy could be somewhere on the Indian Ocean in East Africa, Tanzania or something
Is there any unnamed dinosaur material from there? (Romualdo)
There's a megaraptoran and a spinosaurid (not Irritator, a larger species reaching 8-10 m)
i have a thoery
tyrannosaurus drove albertosaurus to extinction
hear me out
tyrannosaurus showed up around the time albertosaurus went extinct, it also has been found in canada
Angaturama?
Here's the Rufiji River in Tanzania, geologically a good modern proxy
Yeah these lacustrine plains are what I envisioned lol
That's pretty much spot on, and if you saw it from the air they'd be concentrated in these large rift valleys

haha brick's drive has a pdf of it i win
meaning there is a good chance that they did meet, even if it was just tyrannosaurs migrating through alberta, but the rexes would have needed lots of food, food that was more than what albertosaurs needed meaning they would've killed more prey, bullied albertosaurs off of carcasses, and would have even possibly killed unsuspecting albertosaurs, the prey in alberta would not have been built to defend against a grown tyrannosaurus they would be used to the iincredibly speedy and less durable albertosaurs, so the tyrannosaurs could've hunted with ease, too much ease therefore decreasing the prey population due to them being hunted or them leaving alberta, therefore leaving no food for the albertosaurs and starving them out
Isn’t regalis like the same size as annectans if not slightly larger on average
The overcompetition theory is bogus. Less that it’s impossible and more that it’s a very sensational idea backed by nothing but fringe coincidences
Aren’t the largest Edmontosaurus specimens E. annectens?
Yeah but on average
AFAIK they had similar average sizes but regalis had a much smaller max (11m and 7 tons I think?)
Anyways competitive displacement into extinction isn’t that common in nature and there was an entire faunal overturn going on at the time that was probably playing more of a factor
No
When overcompetition does happen it’s a more complicated endeavor than people think that focuses on a myriad of ecological factors. It’s rarely the case that one animal just stomps another out of existence.
it's just a theory, it kind of makes sense of you think about it, rexes need incredible amounts of food to survive, they wouldve killed off the dinos that couldnt defend themselves (which wouldve been most) but yes sense there is no evidence that tyrannosaurus lived in alberta it may just be a couincedence that it showed up around albertosaurs extinction, its all speculation and its fun to speculate
It does not make sense
now that said this image goes so hard
it does
There are some early Maastrichtian deposits with A. sarcophagus or maybe just Horseshoe but it counts for something
They’re quite different animals outside of size. One important factor is that albertosaurs were social while tyrannosaurus probably wasn’t.
“Final boss!”
Did sue get taller
Tyrannosaurus probably lived in a mating pair
Yeh
alberto's just horseshoe too so and i don't know of any tyranosaurini known from there
i like thinking that
There’s nothing to suggest that Tbf.
Albeit idk what evidence would suggest that either
"why do i hear boss music?"
Either way it’s a very different ecological gambit. IE being able to live at higher densities than their larger cousin
It could have or it couldn't, you never gonna really know.
I wouldn’t be surprised if both had a similar method of rearing young tho, and that might bite albertosaurs in the ass
you had gorgosaurus and daspletosaurus living together fine in dinosaur park, although those too were way closer in size then rex and any albertosaurine
Dasp was decently beefier then gorgo tho
Fair actually so nvrmind. Maybe that’s why we found young albertosaurs with adults.
Size difference maybe just makes it easy for Albertosaurus to specialise hunting cursorial prey with less competition.
kid named 1.093m femur
Triceratops are my favorite dinosaur 
true which kinda throws off my whole theory now that i think of it
Agreed
They also concurrently go extinct with the faunal overturn so it wouldn’t really matter
Sue has cartilage in the limbs, the Scotty skeletal does not hence why she's now taller
okay so looking at it regalis might've been larger on average but it could be a sampling issue but i can't check anyways because only the thesis template is accesable and that doesn't have figures
i just got the theory because we dont know why albertosaurs went extinct
(Probably environmental change)
if someone mentions periculosus i'm gonna scream
yeah probably, but its fun to speculate
you talkin about edmonto?
ye
nice
Does this mean the Sue skeletal is better?
I mean, it's a different specimen so they're not really applicable lmao
El em ay oh
I meant, is a skeletal taking in account cartilage better then one without?
did you account for the 1% albertosuarus increase with cmn 5600?
Yea, but as I said, you can't really say one's better than the other considering they're different specimens. You can add the small amount of cartilage yourself anyways
It's ROM 807 so maybe
Very cool and rad
Yeah I know that the sue skeletal is a worse scotty skeletal then the scotty one, but I just meant cartilage vs no cartilage.
me when 10cm longer mandibles
🤷♂️ As I said, you can always add the cartilage yourself, it's a very minor thing
That alberta looks funky, did someone drop smth on its head?
Ha you beat me to it
Something something new skull that seems to be right, but I hate it so I reject reality
sharpe and beagliam both have the funky skull
There is another, but idk if it's "fully" released (and no scale bar so L)
Something in my head tells me "ain't no way that's not a crushed skull"
My reaction to that information:
it looks like mud butte rex skull, as in it seems like it was crushed by a boulder as a small child
gorgeous george rep wooo
love that his name is gorgeous george and he's a daspleto
It's a bunch of skull bits that are put together, not a specific skull iirc. Like unwarped bits thrown together
break the uncreative naming norms george 💪

me i have like 2 separate potential catalogue numbers for an obnoxius period of time
What about a new skull?
Table?
Guy got a chad head. gorgeous indeed.
Gorgeous George is AMNH 5336 but it was described as AMNH 5434 and everyone called in that in literature (the same thing happened with AMNH 5434 becoming AMNH 5336)
And then Gorgeous George moved to the field museum and became FMNH PR 308
And along the way gorgeous George was reassigned to daspletosaurus sp. rather than it’s original gorgosaurus assignment, but the other specimen is still gorgosaurus
Oh
So distortion?
Hesperosaurus holotype casually having four
I heard Sharpes skull is good so probably not?

I think it looks ugly so I refuse to believe it
Sharpe's skull is still being worked on, I think his 2022 reconstruction is ugly as hell but I'll wait for a more detailed one
It just looks uncanny to me
this fried my brain
Same
The worst part is when the actual gorgosaurus specimen is given it’s “original” catalogue number people reasonably think it’s gorgeous George because it used that exact same number in literature
pleasing
the man (why is the femur so big)
idk
why is his skull like that
anotha one
Me pondering my rock
Stegoceras skull will never not disturb me
forgot there was a more recent profile shot of that boi until now
i am also stealing that
Would it be possible Paleo chat for a Dino to use the trapdoor style of taking down prey that the Trapdoor Spider uses All my expertise is in Arachnids
Don’t see why not I suppose?
I feel like it would have been very effective
It’s not really practical for a large animal to do that. Trapdoor spiders are able to have their doors specifically because the structures bound together with silk.
Yes but it doesn't have to be a perfeft 1 for 1, nor does it have to be a large predator. If I am not mistaken there are smaller dinos from around that time, cat sized even
how many animals utilize trap doors
I am not sure
Spiders and people at least
But antlions don't use trapdoors.
The only reason trapdoors work for the trapdoor spider is because of a spider's ability to spin webs. The webs allows them to make intact structures, such as the lid of a trapdoor.
I know they don't. I was just saying it reminded me they exist
Ah. I see. My apologies.
Macro fauna on the scale of Dinosaurs just sound wildly inefficient to try to use anything amalgamating to a “trapdoor” hunting method.
