The skulls of the big three Theropods each serve a purpose eerily similar to human weaponry when you think about it:

Spinosaurus was primarily a piscivorous animal, and as such, developed a slender skull with conical straight teeth to quickly catch and hold onto slippery, struggling prey like a spear.

Giganotosaurus had blade like teeth and a relatively narrow skull with a strong chin that served to cut through flesh with relative ease and induce heavy blood loss with rapid bites, reminiscent to a sword.

And Tyrannosaurus, being adapted to hunting formidable prey like Triceratops, Ankylosaurus and Edmontosaurus, was equipped with a massive, heavily reinforced skull with thick, deeply rooted teeth built to crush and shatter bone with an immensly powerful bite, like a warhammer.

To basically sum it up:
Spinosaurus=Spear
Giganotosaurus=Sword
Tyrannosaurus=Warhammer

[quick lintel]

It also had ears for some reason even though erm they don't have those
It's like a weird amalgamation of reptile and uhh uhh uhhhh mammal and uhhhh uhhh idk

Monkey

[charred hearth]

find more andrewsarchus material or find more gigantosaurus material

[queen garnet]

Ye and it was wiped out during the Permian-Triassic extinction

[wind prairie]

so you're just obsessed with this animal now lol I don't blame you, the permian was in a place similar to the early cenozoic in its primate evolution before the great dying wiped everything clean so there could've very well been human like creatures to descend from suminia

[quick lintel]

Andrewscarchus all the way I love my hell pig not-pig
Andrew is weird because I think it used to be characterized as a wolf thing then was made a pig and then a mixture of both but now it's mostly pig again I think?? I forgor. Andrewarchus recons are strange they flip flop a lot

[wind prairie]

but it's worth noting suminia probably didn't have hair. I don't think it was far enough down the synapsid tree to mammals to have likely had that.
Also suminia had relatives: meet ulemica

Probably due to them not being formerly described, or perhaps because their remains are far too fragmentary to be determined as to what species they are.

[queen oar]

it has good material too, right?

[orchid lynx]

[sullen cairn]

my toxic trait is i have more faith in tatankaceratops than nedoceratops

[wind prairie]

also idk why richardoestia here is an unenlagiine

[charred hearth]

can you explain how you believe it survives in the enviorment?

[sullen cairn]

the same way every other small ceratopsian would

I mean...
no..
but that's besides the point lol

[wind prairie]

a laramidian unenlagiine is pretty special
could it possibly fly too? I know that's supported in other ones of similar size like buitreraptor but idk

[sullen cairn]

richardoestia does not have arm material whatsoever but some of its teeth get kinda big so i'd doubt it

[queen oar]

I mean, I think Table think it is, I personally don't. My bet is just a hormonal juvenile.

[charred hearth]

whats a hormonal juvenile

[gentle pier]

It'd probably be the second largest Oviraptorosaurid after Gigantoraptor, wouldn't it?

[queen oar]

subjective. But basically in this context, it's a individual that either was stimulated by some event in time, or was born with a condition that stimulated the production of hormones associated to growth and development.

[sullen cairn]

longrich suggested it was a genetically malformed freak because everything about it looked like an adult besides the fact it was small and had small horns (never occur in adults of anything) or alternatively triceratops sacrisonorum

[undone rapids]

there's another big ovi in alectrosaurus' formation iirc. table remembers

[sullen cairn]

further compounded by the fact longrich thinks it might be valid nowadays anyways

[charred hearth]

so nedo is invalid but tatank is?

[undone rapids]

It just depends on who you ask

[sullen cairn]

there has been far more put forward to suggest nedo is invalid compared to the one and a half sentence from longrich for tatanka
though this is somewhat mediated by the fact tatanka barely exists outside its description

granted on the same token the only arguments put against nedoceratops (ignoring horner and scanella's paper that was entirely contingent on torosaurus being triceratops) is longrich reiterating the arguments from the 20th century

this is to say someone should probably take a look at both of them again

[queen oar]

with Nedo, nothing will happen. As per usual for Lance Formation ceratopsids.

[sullen cairn]

this is because they lack extremely precise strat data which makes it taxonomically useless to the MOR

[charred hearth]

@balmy oyster i know you love ceratopsians, so i would want your input on if you believe nedo and tatanka are valid or not, i apologize for the ping

[queen oar]

yup!

[tough parcel]

I think we should ask Nedo and Tatanka as to their feelings about validation

[queen oar]

We should try to follow Falcon's example here, guys.

[sullen cairn]

the funny thing here is he proposed that the lack of cornual sinuses implicates tatankaceratops as immature while in that same paper asserting titanoceratops having more developed cornual sinuses than pentaceratops could not be ontogentic

[winter marsh]

lemme hop on my time machine rq

[queen oar]

Just asking, do you know why?

[sullen cairn]

presumably because its contextualized by the other characters distinguishing titanoceratops and pentaceratops seems otherwise mature but like the only other things longrich says are inconsistent with adulthood in tatankaceratops are small size and small postorbitals which is somehow not very compelling

[gentle pier]

Now that I think about it, I should've probably added Alamosaurus as the list of prey species that Tyrannosaurus would've hunted. I just didn't before because it currently isn't found in the Hell Creek Formation, though it did live in Laramidia at the same time as Rex, sooo

[queen oar]

I mean, I guess you could put it as " Potential Prey Item "

[charred hearth]

how big is the gap between the largest predator of laramidia to the 2nd largest predator ( not including Mcraensis )

Bro evolution made this sharks jaw look like it hurts just by even yk

[queen garnet]

So your a marine biologist I see

Can you explain how sharks survived the great dying

[ancient crystal]

Water

[queen garnet]

But water was worse than land

[mellow gale]

How bad is the ocean ecosystem actually?

[ancient crystal]

Not for the sharks it wasn't

[ashen wedge]

Then again we have the babirusa

[full lagoon]

Lots of sharks are hella generalized and rode it out pretty well I'd imagine

[ancient crystal]

What do you mean by this?

[near pulsar]

the bald duck thing has kinda thrown me for a loop
like yeah in hindsight it makes sense but like... HHUH.
Bald duck

[queen garnet]

I wonder why because I heard 96% of marine life was wiped out that’s huge

[mellow gale]

I’ve heard ocean life is getting emptier more and more each year, how true is that?

[full lagoon]

It's every ecosystem on the planet, actually

[ancient crystal]

I mean, yeah, its pretty bad but the oceans are still doing better than a lot of other environments

Reefs are realistically gone in the next 30 years according to pretty much every model, but the oceans are biological deserts. A good 90% of the water column is empty from surface to seafloor at any given time so it isn't like they're dead, this is just partially how they are

Not to say that things are good though, because they certainly aren't

[near pulsar]

slightly offtopic (i guess its kinda ontopic when it comes to marine life though)
this paper published this month was looking at the hydrodynamics and adaptations of plesiosaurs for retaining body heat.. and... it led to some extremely amusing reconstructions of plesiosaurs https://journals.ub.ovgu.de/index.php/techmech/article/view/2328

[full lagoon]

A lot of that statistic was probably organisms that don't even get talked about, and sharks are probably well less than 1% of all life on earth

[ancient crystal]

So there's people who can actually answer your question a lot better

I'm not a paleomarine biologist, I mostly work with trophic ecology and morphometrics of living sharks and don't have a lot knowledge on the greater context of the great dying

[mellow gale]

Are artificial reefs doing anything at all?

[ashen wedge]

I’m not going to lie, I thought this was a Mosa… but then I realized it was a plesiosaurus

[balmy oyster]

Hard to establish them when the oceans themselves are becoming more hostile for coral polyps sustained growth

[little mauve]

The Permian extinction was bad but the rebound was fast, several shark lineages did go extinct, but the ones that survived did it the same way any group survives a mass extinction: being small adaptable generalists that can quickly radiate to new niches once the environment bounces back. There could also be some physiological adaptations that gave them and bony fish an advantage specifically dealing with ocean acidification https://beta.escholarship.org/uc/item/2hb494k6

[ancient crystal]

If you ask me, those are a sham with too little data and too small of a timeline to actually say if they're helpful or not.

Looking into assisted evolution and developing heat resistant symbionts for corals to use has a lot more immediate potential and only then do I think its actually realistic to expect artificial reefs to see long term success

[full lagoon]

A general rule of thumb in organisms surviving periods of stress is that the small generalists will always fare better than large or specialized organisms

[mellow gale]

Is there any good development on assisted evolution for corals?

[little mauve]

There may have been other factors like deepwater refugia but we don't have evidence of it as of yet

Oh wait actually we do https://www.nationalgeographic.com/animals/article/131029-ancient-shark-survived-mass-extinction-science

[full lagoon]

It's honestly hilariously disappointing that we are forced to assist coral evolution because society isn't willing to change the larger issues contributing to ocean die-offs

[near pulsar]

seems like the impression is quite a bit less extreme than the reconstruction they reached in that paper, assuming that the tissue didn't degrade significantly as it got preserved i guess

[full lagoon]

Based on what it's saying, it's only claiming it as a possibility and not as something conclusive

[ancient crystal]

Coral settlement is largely dependent on the presence of an already healthy reef, artificial reefs are not that, they do not produce the same ques as a healthy natural reef

There is a lot of promising science on assisted evolution in corals but the biggest challenge is one that evolution in any form can't fix, that being ocean acidification. You could theoretically develop some algae that all coral species equally love to host, and that can withstand temperature fluctuations in the tens of degrees, but if the skeleton cannot be made then the coral cannot survive.

This doesn't even touch on diseases, pollution, fouling, or habitat destruction from trawling and human development.

[little mauve]

To bring it back to the Permian ocean acidification was a major factor in the extinction of marine life because most of it was invertebrate, thats where you get the 96% number from, vertebrates like sharks actually fared better

[ancient crystal]

I'm sure to survive because my internal anatomy is superior

[full lagoon]

More specifically the damage acidification had on invertebrate skeletons, yes?

[mellow gale]

People suck, humans suck

[little mauve]

Precisely

[ancient crystal]

Inverts cannot handle water quality changes nearly as well as verts can. They die at the drop of the hat mass extinction or no.

Add acidification into the mix and now the shell building animals can't grow, the corals (there weren't really corals yet but who cares) can't make their skeletons, and generally anything calcified on the exterior of an animal is going to be weaker

[little mauve]

The Permian had reefs too, the primary builders were just sponges and bryozoans, algae, things like that. They were all hit hard

[ancient crystal]

Yeah, not corals though because they took off after the rudists kicked the bucket in the jurassic

[full lagoon]

Speaking of rudists, those things are hella underrated

[little mauve]

Rudists were still the primary reef builders until KT my friend

[ancient crystal]

Then I'm misremembering my coral class lmao

[full lagoon]

I'm ashamed I haven't heard of them until relatively recently because they get literally zero representation

[little mauve]

Ya coral reefs are pretty much a cenozoic phenomenon. Rudists are super cool

[ancient crystal]

Damn, I made a mistake on the internet, guess I have no choice but to destroy every cretaceous rudist specimen in the fossil record to save face

[little mauve]

Noooo think of the clam loving children

[ancient crystal]

Its not people, its corporations and leaders

This is a very important distinction to make because this sentiment puts people on the outside looking in off of conservation or non-anthropocentric perspectives. People are generally uneducated about the world around them, but even that is of design and consequence by those in charge knowing destruction is more lucrative in the short term and that they'll die before there are any consequences.

[full lagoon]

Yeah, and I honestly should have specified before putting a fat check mark emoji, but we are moving off topic now.

Mussels do not move

I think you are thinking of scallops, and most likely not because the shape does not suggest it unlike scallops

[wind prairie]

I could've sworn they can move a little bit

ok I guess I thought they could move and then plant themselves and then never move again

[ancient crystal]

No, mussels are entirely sessile

Oh boy, it’s Jurassic World dinosaur models but flipped the sequel!!!!

why do their postures look like that

[wind prairie]

wait now it has a short tail what happened?

[balmy oyster]

Apparently it always had a short tail, but the long tail recons trended over it

[velvet burrow]

Apparently the Allosaurus was made from the ground up and based on a particular specimen

Which like, still means that all that work went into actively and consciously making it a JW allo ripoff

[junior dawn]

they used the same sculpt, but different final model to put it simply. It’s clearly the same sculpt, you can see the same exact croc scute rows, brow details, wrinkles etc, with very minimal changes. The model mesh is technically new, but the details and stuff are the same as the jw allo

same can be said for a bunch of their other designs

im confused as to why this is suddenly such a big debate when the first time around everyone agreed, and a bunch of their other designs are even more blatant lol

which is fine that they are if that’s what they were told to do/all they could do, but yeah

[charred hearth]

why did they settle on those postures? atleast jw allo had a ..decent posture

[junior dawn]

i think that specific pic they’re actively in moment and it might be a bad frame, so hard to judge that

that’s not to say they don’t move weirdly and kinda bad judging by LooP, the allo kept breaking its neck there lol

Ew pronated wrists (if I said the wrong term for it, let me know)

[runic heart]

Oh man… articulated PNSO…. It’s too peak…

PEAK!!

[peak jetty]

This looks great, though i wish it had an exoparia

[runic heart]

It does actually. It’s of the variety that folds into the mouth when closing.

Really hoping they do a carch next

[peak jetty]

OH

I think I see the idea now, yeah

[runic heart]

They did the embargoed lip thing too…. Peak

[tulip dove]

Iirc, it'll have different proportions compared to the concept

"finally I got all the Carcharodontosaurids from PNSO! I'll never starve again"

The humble PNSO introducing a brand new way to steal my money once they do Lucas

[runic heart]

Nah, we’d buy.

[runic rover]

Unfortunately I have to do what I must...

[runic heart]

Embargoed lip study, when you releasing! 🗣️

[runic rover]

Which is getting ganged as if in a wrestling match by creative beasts and PNSO together (they are going to do a Giga apparently, help!)

[runic heart]

Creative beast is doing a giga?

[runic rover]

Someone told me they are, not sure if happy or wanting to cry

[runic heart]

Oh hell yeah. They are redoing their Rex as well.

[runic rover]

I have no confirmation on the giga tho* I just was told they DID officially say it for the next kick, that's why I'm holding ultra back on the beautiful seaguana acro from them

[misty scarab]

Bite force for deinosuchus?

[icy lagoon]

did they use this?

with the changes thal got I'm hopeful they can fix stego

[runic heart]

Problem, the PNSO articulated Rex is

1. Articulated

2. 36cm long (14.5 inches)

How much will it cost…

I’m betting $120

[runic heart]

I’m seeing 2 reactions to this figure: “best thing I’ve ever seen” and “why are you copying botm, stay in your lane”

[ancient crystal]

I thought the february dev log released early and I got excited, how dare you do this to me

[runic rover]

I am usually a little factionary, but in this case I'm like "holy s**t, two cakes!" Kinda. But I DO feel quite nervous for my poor wallet

This year was supposed to be for savings and I have already screwed up.

[ancient crystal]

My wallet cowers before my lack of self control

[runic rover]

Mine is at his like 4-5th step of acceptance or something like that.

[ancient crystal]

And so does my future

I’m pretty good with saving money, but I’ve got Hiya toys Godzilla stuff, Lego Jurassic world and NASA stuff, and now this to worry about. Also space. I’m running out of space for stuff.

[queen oar]

my balance amounts to: ||0||

[left shard]

dude is PNSO expensive? Omg it’s beautiful I might ask for one for my bday

[ancient crystal]

I think someone should just give me a bunch of money and then I won't have to worry about it so much... if only there was a way for that to happen on a weekly or maybe monthly basis... maybe in return for some service or labor? Idk too bad that doesn't exist.

[runic rover]

I have too many hobbies and collection triggers, plus I have started the horribly expensive hobby of wargaming/dioramas

@left shard depends, what's your definition of expensive? Because the base ones are like 60-70€

[queen oar]

maybe become a paleostreamer or something.

[left shard]

I’d say how my life is 50-60usd

[runic heart]

New articulated one could very well be around $120

[runic rover]

There are some that even go around 25-30€ like THE BEAUTIFUL MIRAGAIA

[queen oar]

@ancient crystal hypothetically, let's say I offered you 200k dollars, but in return you would have to destroy a O. megalodon fossil, would you accept that deal?

[hallow spear]

Seems to be based primarily on Matt dempseys muwculature

[queen oar]

@hallow spear do you agree the neck is skinny?

[hallow spear]

For?

[queen oar]

this.

[icy lagoon]

you sure? it looks so uncanny and thin

[hallow spear]

Im sure its def primarily based on dempseys musculature

[icy lagoon]

isn't this based off that?

[hallow spear]

could thicken the soft tissue for the plates or the top of the neck but it seems alright

& no it doesnt seem to be based on hartmans stegosaurus

[icy lagoon]

I mean dempsey's

[hallow spear]

Yeah its based on dempseys

[icy lagoon]

the hips look very wide but i sure hope their tlc resembles this

[queen oar]

What if the neck was bigger?

[full lagoon]

If miragia means anything, I'm hopeful

[icy lagoon]

stegosaurids are all noodle necks, especially miragaia

I believe the jp stego is clouding your judgment

[queen oar]

like this:

[full lagoon]

Oh well that's only showing muscle, not the flesh on the neck

[icy lagoon]

is this ouranosaurus?

[hallow spear]

Would be fine it’s purely muscle

[queen oar]

Nope, Ouranosaurus is different.
#art-channel message

[full lagoon]

The fact that the dinosaur had armor on its neck specifically to mitigate neck bites is so cool

[icy lagoon]

would their neck beads even do anything?

[hallow spear]

It probably wasn’t primarily for that reason but would help @icy lagoon the hips on dempseys stego are true to the material but the hips are very crushed in life they would be more normal

[queen oar]

@hallow spear hey Stego, have I shown this to you before?

[full lagoon]

Wtf lol

[queen oar]

lol

[hallow spear]

You have not lmao

[full lagoon]

Are there other theories?

[icy lagoon]

they served as bone attachments for tiny neck spikes /jk

[hallow spear]

Likely the razor sharp plants it’s eating but it’s essentially chainmail so it would help regardless

[ionic crescent]

I recall paleodude mentioned it likely not being armor per se but some sub dermal layer like xenarthrans (or whatever is said)

Which could be interesting

[icy lagoon]

bro had a armadillo neck

imagine if they were covered in armadillo skin
weren't they covered in smaller osteoderms on their body?

[full lagoon]

Either way it would be useful for lacerations from both it's food and what might want to eat it

Especially given that the predators of the area relied on slashing bites and blood loss

[hallow spear]

Tbf we don’t truly know that, but it is an option for specifically “ossicles”

[hardy sentinel]

Some random bulls**t

[queen oar]

yup.

[full lagoon]

I mean yeah it's obvious

[queen oar]

I have another Stegosaur, but it will depend if @hallow spear wants me to show it.

[charred hearth]

yes, am i beautiful

[runic heart]

@runic rover the tail has wire in it!!

[bitter quest]

Honestly I already own BotM rex but I'm curious if this will be cheaper in pricing

[runic heart]

I imagine since this figure is a good bit larger than typical PNSO, and has articulation, it’s probably closer to the $120 range.

[runic heart]

I might get this figure, but honestly the head shape isn’t really doing it for me. It is a very informed model, but I might wait for an articulated carch. Giga or something.

[bitter quest]

Well at least BotM has competition so more likely slightly lower prices in the future due to that fact

[runic heart]

Yep. Love how everyone is jumping on the articulated dinosaur model train. I’m hoping we’ll get articulated figures from some company for WWD 1999.

[bitter quest]

Real

i did see some people hating on the change for some reason earlier

[runic heart]

I saw the same thing. 2 reactions to this new figure: “greatest thing I’ve ever seen” and “stop copying botm, stay in your lane”.

[bitter quest]

There was one I saw basically saying this would be better if it wasn't articulated

[runic heart]

Honestly wouldn’t mind if PNSO shifted primarily to articulation. This new Rex already looks miles better than their single pose figures.

And yes, this conversation is on-topic, as it is essentially paleoart.

[bitter quest]

I like a mix of the two but anyway random dsungaripterus jumpscare

[lucid gyro]

here i am hoping for an acro 😫

[true juniper]

How big was baryonyx? I've heard people say it was 7.5 meters long, then 8.5, then 10 meters

[runic rover]

Good, I'm waiting for Giga (hopefully will come late... Not TOO Late pls)

[fossil ingot]

Around 9.1m long along the centra and about 2.1t

[true juniper]

Ok thank you

[runic heart]

See, you have most saying that an articulated PNSO figure is the greatest thing in the world. And then you have this guy, and others like him:

Like come on, you’re ruining the fun.

Revise the Allosaurus from THE DINOSAURS of Netflix

[winter marsh]

we just be hating for the game

[outer tusk]

having an opinion is apparently ruining the fun

[lucid gyro]

what’s even the issue with articulation?

[winter marsh]

I dont think its an opinion, I think its a direct jab at BoTM

[arctic crane]

The fan revised one is way better. The original actually looks worse than the Jurassic world allo

Still not a fan of the crocodile like scutes but the original model has them so I get it. Dino docs really have a problem with allos face for some reason

[charred hearth]

they do?

[winter marsh]

most of them destroy half of it so they have less work

[arctic crane]

OG walking with allos have a weird head shape, it's a little better in big all but still not the best

[ionic linden]

haters gonna hate

[runic rover]

"holy sh-**, two cakes" is my constant reply to these kind of arguments.

Besides what kind of company is called haolonggood but doesn't make any Haolong ( 🤭 )

[stiff osprey]

Having articulation does ruin the natural look of the figure, and does make it much harder to stand it upright. He's right

Comparing botm to a dollar store figure is just being a hater though

[runic rover]

WWD is the main reason of why to me Jimmandesi will forever be the best Allosaurus, I just love the longer snout.

[winter marsh]

[charred hearth]

thoughts on pterosaurs doing this?

[flat pewter]

How it should always look imo. I dislike how some of the dinos look on Netflix's series and this definitely an improvement.

[flat pewter]

Idk, I do wonder what the capacity some pterosaurus had for tool usage and problem solving, but I don't think its impossible given that many larger Azhdarchids were predators who had to have larger brains for coordination and ambushing to a degree, so why not? Fossil wise though I don't think we have a lot of proof of tool usage in them.

[arctic crane]

Daddy tops if the best character bro. What are you talking about. Absolute Chad

[wind prairie]

I know I'm saying he's good

[balmy oyster]

People want dino toys that move how do people not realize this

[arctic crane]

Depends on a few things
How intelligent were pterosaurs?

How dexterous were they while flying?

Did any of them hunt ground prey while also remaining agile flyers?

[charred hearth]

uhm
idk

idk

no?

[outer tusk]

what does it mean to be an agile flier?

[little mauve]

Brains were smaller relative to their bodies than similarly sized birds, their brain architecture for balance, vision, and coordination is quite large though

[arctic crane]

The way hawks and eagles are fast and maneuverable and are able to fly and glide for a while.
Dimorphodon and thalassodromeus both hunted prey on the ground but aren't believed to have been as strong a flyer as a hawk

[outer tusk]

dimorphodon yes but Thalass idk

[little mauve]

https://www.eurekalert.org/news-releases/538441 summary of a study on the brains of Rhamphorhynchus and Anhanguera

[arctic crane]

I'm bad at explaining myself.
Could any pterosaurs fly like this but also hunted terrestrial vertebrates
https://youtu.be/2CFckjfP-1E?si=pPXMW5FoYTVABOfe

[little mauve]

Many pterosaurs were extremely agile fliers but they generally didn't develop hawklike forms

[light osprey]

Birds were doing this in the Cretaceous actually

[little mauve]

Yeah exactly

[arctic crane]

I'm sure there were many pterosaurs that were great fliers, but did those ones hunt terrestrial vertebrates? Seems that most that did evolved to be good at running and jumping. I'm sure Anurognathus could fly like that but it mostly ate bugs probably

[lucid gyro]

aren’t paleontologists kinda stumped on how the bigger pterosaurs actually flew or took off

[stiff osprey]

No we've figured it out pretty well by now

They crouched on all fours and used the wing muscles to catapult themselves into the air

[arctic crane]

Ya, but the original question about using fire to hunt was about pterosaurs, or spreading it I guess

[little mauve]

No the best fliers like you said were hunting insects and small vertebrates. Ground stalking seems like the primary way pterosaurs hunted larger vertebrates

[charred hearth]

is it true pterosaurs are more "efficent" fliers then birds?

[arctic crane]

I figured. I could see them stalking around the edge of a wildfire though. Taking advantage of the chaos and if the fire spread their way they could fly to safety

[little mauve]

Pterosaurs were not using tools to spread fire in the Cretaceous, it's a very rare behavior in birds today only seen in certain raptors which are highly derived and not a good model for pterosaurs behaviorally or neurologically

[little mauve]

That is much more reasonable and we have many examples of fire adapted ecosystems in the Mesozoic, fires were probably very common in certain places at certain times

[little mauve]

Terrestrial stalking and quad launching would make larger pterosaurs very effective hunters at the fires edge in the way you described

[arctic crane]

I've also heard that. I think they mean that the reason why some pterosaurs got as big as they did while still being able to fly was because their takeoff method was more efficient than larger birds

[halcyon cobalt]

at least weight-wise

[velvet burrow]

I'd say you don't need to do that if you hunt terrestrial vertebrates

[ionic linden]

[arctic crane]

Agreed, but are there any pterosaurs that can do stuff like that while hunting terrestrial vertebrates

[ionic linden]

dude looks like a mix of kaprosuchus and indoraptor (respectfully ofc)

[charred hearth]

what jurassic world film was the most accurate in its depictions of the animals

[little mauve]

None of them because they're all still using the same late 80s paradigm established in the first movie which was current for the time but is now totally outdated

[runic heart]

I don’t think a sauropod is supposed to go down like that.

[winter marsh]

fallen kingdom was prob the closest

idk tho

[arctic crane]

Looks like a juvenile. Makes sense. Morgan Freeman even says it's the smallest member of the herd

[compact leaf]

A small one going down like that if it’s like a harsh winter is fine (I doubt they’ll say that) but it is weird that the other sauropods just don’t react or freak out

[arctic crane]

Maybe they just didn't like that guy

But ya that's a good point. That sauropod's neck is small enough I could see the predator doing lethal damage. It could have been nice if the herd turned to defend it and the theropod just had to wait so it to die of it wounds and the herd to lose interest

[little mauve]

Once the yutyrannus takes down the sauropod the threat is neutralized, I don't know why they should do anything more than flee

[arctic crane]

I guess it depends on the temperament of sauropods. Some mammalian herbivore moths will defend dead calves for a long while after death from a predator. I know dinosaurs and mammals are very different but its something to think about

[little mauve]

Because mammalian mothers are hardwired to invest an incredible amount of energy into pregnancy and rearing offspring, dinosaurs particularly sauropods were not like that

[arctic crane]

True sauropods specifically had the whole baby sea turtle thing right

But if their instincts are to defend members of the herd I could see them at least making a fuss before they realize it's dead. Depends I guess

[compact leaf]

The thing is they don’t even get shown fleeing there’s just nothing out of the rest of the herd, if that’s the actual full clip it just comes down to anticlimactic writing

[arctic crane]

Well they're not on camera anymore so they don't exist lol.

But I guess the question is did sauropods defend members of their herds like buffalo or was it more of a we are only in group so it's less likely I get attacked type of thing

[little mauve]

Unless sauropods were staying with their nest mates their entire lives and reuniting with their mothers at adulthood, which seems very unlikely, they'd be less inclined to risk their lives protecting an unrelated animal and adult sauropod herds were most certainly composed of unrelated animals. It's called kin selection

Mutual defense comes from strength in numbers, more eyes and ears out for predators, and yeah the buddy system. As in i dont need to outrun the bear i just need to outrun my buddy

Cape buffalo herds are made up of a central core of related females and their offspring. That's the root of their aggression

[arctic crane]

More a flock of songbirds than a herd of cows gotcha. It's gotta suck to be a young sauropod before you become a massive behemoth

[little mauve]

Yeah a baby buffalo is like a 2+ year investment for the mother, you wouldn't leave it behind if it got killed either. Sauropods are the complete opposite

They'd be very vulnerable for sure

[compact leaf]

I could see a loose “you get protection by virtue of me being here” system for a sauropod with a lot of younger animals in its vicinity

[charred hearth]

How good of parents would marine reptiles be?

[runic heart]

Is this actually the material we have for the candeleros monster?

[outer tusk]

yes

[little mauve]

Yeah I think hatchlings were pretty much totally on their own hiding and foraging alone or in groups like other small dinosaur herbivores. Larger juveniles and sub-adults probably had a mix of behaviors in different species from totally age segregated, which we have some evidence for, to trailing or intermingling with adult herds

[charred hearth]

what would be the largest terrestorial carnivore the map of riparia would be able to support?

[little mauve]

Very good in some groups, potentially some of the best reptilian parents to ever evolve

[charred hearth]

is it because of them having less off spring?

[arctic crane]

Do we have any evidence of parental defensive behavior in non avian dinosaurs? Some crocs and birds will defend their eggs and young. Komodos will defend their eggs but leave before they hatch

[little mauve]

Yes, larger fewer offspring born alive take more parental care. It's taken to the extreme in plesiosaurs though

[runic heart]

It’s actually not a horrendously low amount. Surprised it hasn’t been formally named.

[little mauve]

Communal nesting in some groups imply social defense of some kind, so like hadrosaurs and certain theropods probably. Sauropods also deposited their eggs communally but we already covered that, they weren't tending or guarding the eggs

Nest guarding is variable in alligators down to the individual, their parental skills are impressive certainly for reptiles but somewhat overstated as well

So it probably varied a lot, possibly even also to an individual level in solitary nesting species

[arctic crane]

Some snakes also guard their eggs or even young, but most reptiles do abandoned their eggs. I think spawn guarding is seen in some amphibians and fish too

Do we have any nesting material for other ornithopods like ceratopsians or thyreophorans?

[compact leaf]

Amphibians and fish both exhibit spawn guarding of varying levels with some fish taking it to a pretty far extreme

[charred hearth]

leed keeps it babys iwthin its mouth to protect them

[compact leaf]

We actually have trackways that seem to show all three of those behaviors for older juveniles it’s pretty cool

[little mauve]

Protoceratops and that's it apart from eggshell and neonate fragments

Scratch that, I'm getting protoceratops mixed up with yamaceratops and that was a misidentification anyway. No we don't have any nesting material for either group afaik

[little mauve]

I also like the idea of them reverting to a solitary lifestyle at the largest sizes

[left shard]

What pterosaurs could we ride (that are not haztegoptetyx… without destroying their back in mind)

also hands down what would be the most efficient dinosaur at taking out humans in this picture here (my opinion is nanotyrannus)

[ashen wedge]

Wait are all of these from Hell Creek and all valid species? Cause if so, I am excited, and I would also say that any of the juveniles of the carnivores would go after us, including the Rex, and adult Nanos

[compact leaf]

I could definitely see that happening in some species

[topaz shell]

Nedocerarops? Also I feel like any decently sized (compared to us) theropod there could dispatch a human

[ashen wedge]

Question…. Is Stygi distinct from Pachy since I saw from online that there is some evidence claiming it’s not an immature Pachy?

[stiff osprey]

This is hell creek + lance + frenchman + whatever other nearby formations

[ashen wedge]

Which of these locations besides Hell Creek had T-Rex in them?

[outer tusk]

all of them

[ashen wedge]

Alright, just making sure

[stiff osprey]

Yeah the point of lumping them all together is they all share the same fauna with a few exceptions

[runic heart]

I forgot, is the grouping of Pachycephalosaurus, stygimoloch, and dracorex into pachy being rolled back?

[ashen wedge]

I don’t know, but I saw something online and I wanted to check with y’all since y’all have more knowledge on the subjects and have more access to the papers and stuff than I do

[ashen wedge]

(Feel free to Correct Me if I’m Wrong about this information since I’m going off of my memory of last what I heard)

Regardless, I believe that they are all independent despite lacking proof for that, but I say this due to other Pachycepholosaurs (not the main three but the other members of the family) have had some flat headed members (throughout life), so I say they are all valid since the species is a weird one…. Any case tho, it should be noted that there are other Pachycepholosaurs (not the main three but the other members of the family) have had members have flat to dome heads (from birth till death), and dome heads (all the way throughout life)

[left shard]

I believe it is or could be a subspecies of patchy and dracorex is a juvenile of stygy or could be a valid species (I personally hope it is)

[ashen wedge]

Yeah, as I am just confused on it (as I hope all three are valid, although I would accept if Stygi was subspecies and Draco was Juvi for both)

[left shard]

Dracorex my boy

[ashen wedge]

The Dragon King of Hogwarts, I hope it is not a juvie…. But it possibly is (it’s 50/50 for me)

[lavish frigate]

Any oviraptorosaur because they can whisper the hidden knowledge that many of them probably didn’t have keratinized crests into the ears of any human and kill them from sheer Eldritch knowledge alone

[charred hearth]

does anyone know any better matching fit for sceptile? as i believe another dinosaur or prehestoric animal repersents it better

[arctic crane]

Well giga should have fossilized better if it wanted us to know more about it

[lucid gyro]

there was new material found in argentina but i think that was announced like a year or two ago

[thorn grove]

that dont mean it's a new species

[lucid gyro]

yea i know i lowk meant to reply to what headless said about how it should of fossilised better so we can learn from it lol

[fallow plank]

Paleo chat, just a quick question who was the bigger species between Eo and trike in terms of size?

[charred hearth]

Trike

[scenic flame]

grey is eotrike

[fossil ingot]

Another Comp here

And here an Edit of Eo but with Fadeno skull of it instead

[brave nova]

Still doesn’t make sense to me that this eo is 6t

[fossil ingot]

Eo is about +7m Along the Centra, which gives about +5t based on what Random's list had Trikes of Similar Length

Iirc Feilongs Eo got +6t cause it uses an Older Dorsal of Trike that was more Barrel Shaped in Comparison of Random's who uses Demphy's

[outer tusk]

either one isn't giving you that awful 2007 esimate though just fyi

[brave nova]

Ic, yea I was always going on eo being ~5t but then feilong did his volumetric. How longs that eo there anyway? Since I never really looked into it

[fossil ingot]

Feilong used GSP For his Eo and thats why he got +6t at 7m

[brave nova]

I see. So it’s likely not 6t?

[fossil ingot]

Eo should be about 7m along the Centra

[fossil ingot]

If you use the same Dorsal Random uses which is Demphys then yeah Eo isn't 6t, if you use GSP Trike Dorsal than yeah you get +6t
However iirc Stego mentioned that Demphy's should be better to use

[fossil ingot]

True

[fossil ingot]

Demphys Helped on it so its pretty decent

[icy lagoon]

now it's pot's turn for stego's tlc

[fossil ingot]

True

[fallow plank]

https://tenor.com/view/rocket-raccoon-i-am-groot-shorts-bradley-cooper-what-am-i-reading-gif-27609014

[frail robin]

Why do some paleoartists portray Pachycephalosaurids/Ceratopsians/Stegosaurids with cheeks on their mouths and some don't?

[stiff osprey]

There's no evidence that they did or did not have cheeks

[lean pebble]

he's mine

[runic heart]

It’s definitely likely for a ceratopsians jugal to be support for a cheek area, correct?

[stiff osprey]

Oh yes, but the jugal is at the very back of the mouth, it doesn't cover most of the toothrow

[outer tusk]

[paper parcel]

JURASSIC PERIOD IS PEAK

Especially with the forests at the poles and sauropod diversity, and stegos

[keen tundra]

Enyone have a good size comparison between diplodocus and allosaurus

[runic heart]

Those massive barosaurus specimens are all attributed to supersaurus now, right?

[icy lagoon]

we need stego's tlc to cook like pk did

[keen tundra]

I love it's necks

[thorn grove]

does this work?

[keen tundra]

Thank you

[runic heart]

Noticing plate pattern similarities. Would they have had a pattern like this?

[runic heart]

Or is it purely speculative in both cases?

[frail jolt]

prob speculative cuz we never found any skin coloration on stego

[tough parcel]

Speculative (and I believe completely unlikely for the first one)

[woeful falcon]

they're not all that similar either when you take a closer look at them.

PK stego's plates look more like they're covered in scutes, while the other is more like a waffle cone

[runic heart]

Ah I see it now. These are actual plate scales.

[paper parcel]

Could allosaurus survive the african savanna?

https://tenor.com/view/allo-the-allosaurus-the-isle-islecord-takes-what-it-wants-gif-25299574

[frail jolt]

prob eat rhinos, cuz they jus weaker stegos kinda, can sneak up on small prey, is preaty fast, large, and social, so ya probably. only threats are MASSIVE crocs, like, bigger than usual, hippos, and elephants

[charred hearth]

hippos...? really...?

[frail jolt]

a sneak attack could beak a leg bone maybee if small allo and big hippo, drag it into water

[charred hearth]

if you laugh you get senmt to hell ( creek )

[frail jolt]

hah

i died

[thorn grove]

why would a hippo sneak attack an allosaurus

like what is the motivation there

[frail jolt]

if allo goes for a sip. they kill antelops and stuff if they get close

[thorn grove]

ik hippos are aggressive but there's a difference between being aggressive towards animals smaller than you and sneak attacking a predator that probably could actively prey on you given the opportunity

though I suppose I have seen them have stand offs with elephants which is certainly not a favorable match up for the hippo on average, but again that's different from a sneak attack

[charred hearth]

the antelops are actively in the water or close to it

[frail jolt]

fe, mb

ig then only threat is massive crocs and elephants, maybe a pack o' lions, but i doubt theyd go for that. so allo has like, ~65-75% chance of survival

[charred hearth]

would crocs really threaten allosaurus

[frail jolt]

if its big enough dffinetly, crocs can get up to like, shy of 30 feet, small allos are like 25

[paper parcel]

im pretty sure allos could kill hippos via bleeding them, specifically on their legs

[thorn grove]

no they don't the largest crocodiles today are like ~20 feet max

[frail jolt]

oh, i swear i heard of 30 footers mb

so only elephants then ig are a threat to allos, but they're usualy neutral

[charred hearth]

thjeres another, large threat to allosaurus's

[thorn grove]

as long as it could obtain sufficient food it would be fine

I'd expect it'd prey on elephants, rhinos, hippos, and large bovids, as well as snapping up smaller animals when the opportunity was there

allosaurus isn't invincible but realistically nothing in the African savanna is going to go out of its way to attack a 3 ton carnivore which they're unfamiliar with

[frail jolt]

wuh

[charred hearth]

american poachers

[frail jolt]

elephants go in heards and even 3 allos couldnt beat a herd of elephants

[charred hearth]

??

[thorn grove]

herd animals don't engage in pvp combat like path of titans groups

as long as they were able to scatter the herd and isolate an individual allosaurus could absolutely prey on an elephant

[frail jolt]

k fair enough

[charred hearth]

aside from poaching

would American mastodons still be able to survive in modern day america or no?

[thorn grove]

there's probably insufficient habitat for them in most places between urban environments and farmland

[frail jolt]

where in america

[charred hearth]

how about...yellowstone

[native kindle]

not enough foliage yeah. humans killed too much of it off for a substantial population of megafauna to exist in most of america

[thorn grove]

maybe a small population could survive there but it'd be tough

[frail jolt]

not enough food, but if people somehow sneak in and plant the food mastodon ate then maybe but that aint gunna hapen anytime soon

[charred hearth]

were mastadons plant generalists or did they specialize in a type of plant they ate?

if they were generalists, would they be in competetion with elk and bison that also live in yellowstone?

[frail jolt]

no specific stuff, other than like twigs woody plants leaves cones and bark, so depends on what they eat

[paper parcel]

Not exactly related but the reason they don't shoot people in the legs to slow them down as cops is because alot of the veins and vessels are located there, so a allosaurus hitting a hippo right there would be a problem

[charred hearth]

???

[native kindle]

how is this at all relevant

[paper parcel]

Bleed

[charred hearth]

???

[thorn grove]

allosaurus would've mauled stuff to death and breaking major blood vessels would speed that up

[paper parcel]

exactly. like the leg

[queen garnet]

Guys should they add cretoxyrhina that shark seems cool to add

[balmy oyster]

Nah add megalodon

[paper parcel]

better idea, the WHOLE MORRISON FORMATION

[bitter quest]

https://tenor.com/view/clams-gif-9259808

[balmy oyster]

What’s funny is that since lancian has made this the faunal count has probably nearly doubled (described and undescribed, definitely a TON more we haven’t found or ever will)

[paper parcel]

sauropods make up like 27 percent of the morrison

[balmy oyster]

Based on…?

[paper parcel]

mod makers idk but there were a lot

[balmy oyster]

Sources say Minecraft and Path of Titans modders are the go-to for paleontology confirmed??

[paper parcel]

well the prehistoricfauna mod is highly accurate and detailed, I even randomly googled some of the creatures and plants and yeah, they align perfectly

[balmy oyster]

What does this have to do with your initial claim?

[paper parcel]

the modders of prehistoricfauna are the ones who said that the morrison is 27 percent sauropod

[balmy oyster]

What were their sources? I know we definitely are missing a huge chunk of Ornithischian & Theropod diversity but based on an abstract about the Morrison we’re also missing a huge chunk of sauropods as well.

[paper parcel]

https://en.wikipedia.org/wiki/List_of_dinosaurs_of_the_Morrison_Formation no idea but sauropod diversity Was high in the morrison

[balmy oyster]

Yes

[paper parcel]

honestly though, I think the jurassic is underrated, the absurd amount of sauropods, dry environment, variety of stegosaurs included

The original taco

[balmy oyster]

I’d argue the Jurassic is a lot more normal to what you’d expect mesozoic ecosystems to be like

The Cretaceous lost the plot and we got some really weird megafaunal animals

[runic heart]

Imagine an entire Morrison formation game, but it’s basically just sauropod zone wars.

[pallid heath]

Opinions on this fella?

[winter marsh]

behold, 20 bigbacks and some other stuff

[little mauve]

I don't know where the 27% claim comes from but here are some figures on vertebrate diversity in the Morrison from Foster's excellent book

[paper parcel]

Probably not, I'd imagine there would be a sauropod limit or they would run out of food if it was pot map sized

[paper parcel]

This game needs more of those tbh

[thorn grove]

my friend has that book

[little mauve]

It's very good highly recommend it

[thorn grove]

I'll probably just borrow his lol

[charred hearth]

do you guys think smilodon would still be able to survive in south america? ( lets use the Pampas as our location )

[paper parcel]

Would probably need smaller teeth since there isn't mammoth sized prey in south america

[charred hearth]

smilodons were not preying on mammoth sized prey i dont believe ToT

[thorn grove]

https://www.youtube.com/watch?v=DpjrR0TB5Is

Stephen Wroe has some videos going over saber teeth

[gleaming talon]

Because they died

[charred hearth]

may i have a quick summary?

[paper parcel]

Specialists have a hard time in a changing world

[runic heart]

Not all dinosaur games have to be survival games, something a lot of people don’t realize. Imagine a territorial sauropod battle game that takes place in the Morrison formation.

[thorn grove]

I'm rewatching it now it's been a while

[thorn grove]

Basically the big benefit that large saber teeth with a sharp cutting edge provides is that it can dispatch prey much faster than the smaller, conical teeth that modern big cats have. These teeth of require a slow suffocation process which can be dangerous when you're holding onto a prey animal larger than yourself.

The downside of this is the often discussed and maybe overexaggerated fragility that these teeth have (which is a downside not just for hunting but also feeding, since it limits what areas of a carcass are safe for eating), as well as that these teeth require a stronger body plan and longer neck to more reliably have the prey be still enough in the correct position for the saber to be used (which sounds good but probably limits their speed). In general the saber toothed body plan is probably more appropriate for large prey for these reasons.

[paper parcel]

Dinosaur, rts game

[tender dove]

Smilodon evolved for a certain world, and when that world no longer existed, they went extinct

[winter marsh]

primal carnage and D-day

[thorn grove]

it's not just Smilodon, as Wroe points out, saber teeth have evolved independently in 4 separate lineages in the Cenozoic alone with over 130 known species possessing them

[winter marsh]

we still have sabertoothed hunters nowadays, theyre just hundreds of kilos heavier and use their big lips to suck out shellfish

[sterile trail]

Walrus lol

[paper parcel]

btw in old/medieval art walrus are depicted with a mans face due to how similar they look(and walrus have facial hair similar to men)

[sterile trail]

I need to look this up now

Oh my god this is so weird

[charred hearth]

@hallow spear hiw accurate is prehestoric kingdoms baby stego?

[hallow spear]

Not very accurate honestly, we have the limbs and scapula of a juvenile stego

[charred hearth]

what would you rate prehestoric kingdoms stego overall accuracy wise?

[icy lagoon]

the adult is a 10

[charred hearth]

is it?

[hallow spear]

S. Stenops is probably a 9/10 only being let down by the plate order/articulation(they don’t follow Saitta 2025) as well as the scapula being set too far up, OR the anterior dorsals facing too downwards without the corresponding incline of the sacral which affects the dorsal spine posture(obviously can’t truly determine the sacral specific thing) and the thagomizer orientation not being like the articulated Dacentrurines, and or based on GSP 2021/2023 and Bakkers work, the tail may also be too short.

Plus I obviously am unsure about the proportions they may be based on Sophie, not an adult specimen

Nonetheless, the best media depiction to date imo

[hallow spear]

There is evidence stegosaurs probably didn’t have cheeks or at least not extended ones https://x.com/Sketchy_raptor/status/2027877679563776094

Dr Matt Dempsey (@Sketchy_raptor)

@SmashAssemble @Fang83768513 The case of "cheeks" in ornithischians isn't really a one size fits all case.

Many of the features we interpretationally associate with extensive "cheeks" in other ornithischians aren't really a thing in Stegosaurus. The temporal jaw muscles would have been more typical... (1/?)

X · Feb 28, 2026, 10:44 PM

[charred hearth]

the way i immediately got this post as soon as you replied ToT

[hallow spear]

I don’t see how they are perfect, they seem to have noticeably longer legs relative to what is actually preserved by the best preserved young juvie

[thorn grove]

were stegosaur teeth used in any kind of actual mastication or were they simply for acquiring vegetation? if the latter cheeks would seem like a hinderance if anything

[hallow spear]

This is covered in the post by Dempsey please read it!

[thorn grove]

i cant i dont have twitter :(

[lavish frigate]

Anyone know anything about the oviraptorosaur on the second row?

[runic heart]

So minimal chewing that didn’t require cheeks.

[hallow spear]

Chewing is present, there is evidence of such, but orthal chewing which is backwards motion of the lower jaw, like a slicing motion one could use it as

[runic heart]

Makes sense

[runic heart]

Also, is there evidence to suggest that the plates would have giant scales like that? Or is it speculative.

[hallow spear]

It’s not scales it’s a type of keratin, but it is speculative, still plausible though

[runic heart]

What about the larger scales on the actual back?

[queen garnet]

I think humans ca survive the Permian Triassic

[hallow spear]

Speculative

[tender dove]

You're right, the title of the video says sabertooths, not Smilodon

[zealous ravine]

Though some ankylosaurs iirc have bigger scales surrounding osteoderms, so not entirely unfounded

[hallow spear]

Yeah but it’s still speculative for stegosaurs I didn’t say it was unfounded emi!!!!!!

[paper parcel]

Scuttelosaurus, a basal thyreophoran(stego, ankys) thought it was funny

basically stego taco

[wind prairie]

I wish people said that about their taste in humans more often

[ionic linden]

seems more like a nodosaurid version but yeah i see what you mean

[charred hearth]

Do we think they'll be size accurate when leed gets added?

[fossil ingot]

Prob no
I doubt they will make a Leed thats shorter in Length than Rex
Will Prob get a small upsize like most 5 slots

[tender dove]

I don't see how something bigger than a Tylosaurus could be contended with unless it takes a while to grow

[stiff osprey]

well it should have a lot of health but shouldn't do much damage given it's a filter feeder

[charred hearth]

leed is still 40 tons, correct? or did it get downsized

[stiff osprey]

12 meter leeds definitely wouldn't weigh 40 tons, maybe 20
although the 16 meter estimate is still plausible afaik

[charred hearth]

if im correct, the largest animals in PoT are
1 - leed
2 - rex
3 - spino..?

[gleaming nacelle]

IF ONLY I REX WAS HERE?

[charred hearth]

?

[gleaming nacelle]

indomo rex

[charred hearth]

whats a indomo

[thorn grove]

indominus

[charred hearth]

oh, how much did that weigh, 13 tons?

[queen oar]

pretty much.

[outer tusk]

the largest specimen is ~17 tonnes

[charred hearth]

dang, so nothing PoT is over 20 tons?

[runic heart]

Was Palaeorhincodon actually a generalist feeder? Or strictly a filter feeder?

For surviving earth

[coral forge]

isnt indom like 5.5-8t meaning we've pretty much always had rexes bigger than indom

[charred hearth]

is that its actual weight in universe?

[coral forge]

depends on who you ask, but that's the range of sizes ive seen

[fossil ingot]

Most Stuff have her at 10.5m
However
She had no Weight on the Internal Guide

[charred hearth]

if indom was a real creature, do you think she would be apart of tyrannosaurini or Giganotosaurini?

[coral forge]

according to Mattel she's 7.2t, according to the internet she's 5.5-8t, according to official sources she has no known weight, according so some random book she's 10.5t
@charred hearth giant megaraptor

[charred hearth]

she does not bare resemblance to one at all

[coral forge]

giant megaraptor with a tyrannosaur skull

[fossil ingot]

She has 9-10.5t on Some Cards and other Books
However the Real Answer is we have no weight
But she is Consistantly Stated to be Larger than Rexes who are 8.4t
So 9-10.5t Checks out, Giga was 9-9.2t

But thats off the Topic

[fossil ingot]

Probably Rex due to her main DNA been well Rex
Giga was only used to get her Big
But Correct Answer us Probably none lol

Well it goes without saying

Though it is THE first time in recorded geological history multicellular stuff started popping up in mass numbers so you’re bound to get some really wacky things swimming about

[rich vessel]

Eh true

[paper parcel]

Wish there was another cambrian explosion like event right now, too many species are dying out

[balmy oyster]

Usually such faunal explosions like that stem from after pretty major extinction events, like with the triassic after the Permian

So if there were to be another kind of explosion like such it would have to be after everything and everyone…is dead.

[paper parcel]

Theortically you could just turn humanity into dinosaurs and it would work, humanity itself is not the problem, its the things it creates and the inherent will to power and destruction.

[little mauve]

We're only 65 million years from the last mass extinction, in equivalent mesozoic time that puts us in the very early Jurassic

The Triassic was ~50 million years long

[pallid heath]

Hot take: I like T. rex feathers

[balmy oyster]

That is a hot take considering everything we have of rex points it to being sparsely feathered at most

Bulky sauropods are peak, and yeah it literally is the same thing, just less big neck bones

[outer tusk]

using salta as a related sub for Isis, but they're actually kind of similar minus camara is longer likely dorsally and Isis likely being wider

Bruhathkayosaurus would be one of my favorite sauropods if it ends up looking like isisaurus.

https://x.com/Rainmaker1973/status/2028007328130163120 is this how massive mammoth herds would've been?

Massimo (@Rainmaker1973)

A large elephant herd.

In the year 1500, there were over 25 million elephants in Africa.

By 1900 this had fallen to 10 million, and by 1979 down to 1.3 million. By the mid-1990s they were below 300,000.

This is a photo from 1976.

[stiff osprey]

Probably not, this was a drought exclusive phenomenon iirc

This is a good representation of an edmontosaur herd tho

[charred hearth]

Sauropods too? or is it too many

[balmy oyster]

Maybe some certain species

[pallid heath]

Yeah I’d say

I just like the feathers cause of aesthetic but I do kinda believe they would have retained some feathers because a few scale imprints aren’t gonna mean it’s entirely scaly

[charred hearth]

like smaller ones / juveniles that would need such large herds for protection?

[little mauve]

We don't have evidence for herds of this size in sauropods, it's possible some were doing it but it's also possible they were limited to smaller groups

Why do all the depictions of the new spinosaurus depict it as lipless knowing full well that the spinosaurus lip debate ended when they figured out that lips were the only sane option for spinosaurids?

[balmy oyster]

this is because this statement is wrong

...at least for Spinosaurus. Sucho & friends probably kept their lips

[charred hearth]

how did spino kiss eachother without lips...?

[stark spade]

with blood

q.lawsoni is still the most complete human+ sized azhdarchid at the moment?

[frigid delta]

could spinosaurids like those you just named can close their nostrils and ears to stay under the surface for an extended period of time much like crocodilians?

[balmy oyster]

Not a clue, we have no evidence of this

[stiff osprey]

no evidence for or against but i think most semiaquatic tetrapods do that

Hard to be aquatic if you're at risk of drowning every time you submerge

[frigid delta]

do you love spiky Shant (left img) or smooth Shant (right img)?

[ionic linden]

smooth shant feels right
spiky shant looks right

[frigid delta]

is Palaeophis the largest Sea Snake?

[runic rover]

FOR NOW, yes.

[neat drum]

A quote from last year with now invalid information if we go by sereno et al 2026 and another upcoming paper #WaitForThePaper

[ashen wedge]

How would one taste?

[ionic linden]

probably like steak and chicken if im being honest

[runic rover]

Crocodiles taste like bird, and birds taste like birds, so my educated guess is that they may taste like bird. Now idk if chicken, turkey or something else.

[true juniper]

How stinky would t rex be

[steep atlas]

Depends how recently it ate a rotten carcass

[ashen wedge]

But they aren’t carnivores tho, so it wouldn’t be crocodile or bird like in taste

[runic rover]

I'm calling in the 2 closest things to it (archosaurid and... Archosaurid (but a lot lot later.) idk pick a herbivore bird and that's the closest taste.)

[ashen wedge]

Fair, but then again there has been millions of years of differences

[hallow spear]

The one thing that is interesting to me is why the skull is so different to all the other recons

[hallow spear]

Also is the dorsal based on bricks edmont or siws dorsal (which is an old edmont edit)

[runic rover]

Billions of years of branching away from eachother still didn't stop them from tasting very close in modern days, so really I'm putting my money on bird tasting

[ashen wedge]

I’m putting it on a mixture between bird and cow

[outer tusk]

Okay I know am out of touch but how much different is Fishy's skull from other

Cause am thinking it's just has a less noticable rectangular jawline

[ashen wedge]

Why do I believe either or would be correct

[icy lagoon]

who made this?

[bronze storm]

Ima have to go with the spinky shant souly off the isle

[thorn grove]

This is using the first skull recon in Hu 1973 for some reason which is a strange choice since that one is missing the nasal and some other giblets

[queen oar]

both.

[solid whale]

Yeah um , spino didnt smack the ground and killed things 10 meters away cuz of it ???

[balmy oyster]

Other reconstructions squash the nasal which I find odd

[runic heart]

Mark your calendars, June is once again Dino Month. (Surviving Earth)

[thorn grove]

Not saying the nasal isn't squashed but the original recon didn't actually put it on the skull anyway hold on

[queen oar]

don't know why yours look compressed like that.

[queen oar]

yeah, assuming this is the same specimen of " Huaxiaosaurus ", I don't think they mention the presence of a nasal bone? Could be wrong though, It has been what...

2 years since I didn't read that paper again?

[thorn grove]

does not appear to include one

[queen oar]

#yup

[thorn grove]

from Xing 2014: partial left nasal of Shantungosaurus giganteus (ZCDM HS0008)

which appears to just be edited onto Hu 1973's recon

[true juniper]

Is it true that tyrannotitan had a deeper chest than it's relatives because it's pubis Is longer

[balmy oyster]

https://tenor.com/view/this-guy-moana-youre-welcome-maui-gif-9761323

[icy lagoon]

so pot bars was shant all along?

[balmy oyster]

Yeah

[drowsy venture]

Whats the study on dinosaur brains?

I’ve heard T-Rex was smart as a crocodile

[undone rapids]

We dunno, one of the newer studies just said we should really not expect them to be like crocs or monkeys but their own thing. There's no real way to estimate intelligence in dead animals, best we can know is they'd be smart enough to do things they needed to do to survive.

[little mauve]

There are two main things we can study with dinosaurs with respect to brains and behavior. The first is relative brain size, from endocasts we can estimate brain size directly and compare it to the mass of the animal. This is known as EQ and theres a different relative scale for reptiles, birds, and mammals because each group clusters with itself. The other thing we can look at directly is brain anatomy, how the brain is structured and shaped, what regions are larger or smaller. That can be trickier but gives us finer detail. Based on these two areas tyrannosaurus had an EQ similar to a crocodile as well as similar overall brain anatomy. Large theropods were conservative in their brain development and what they have is basically plesiomorphic for archosaurs as a whole. That being said there are major limitations to what we know or can know. Though it had a brain similar to a crocodile a tyrannosaurus or any other theropod is occupying a totally different niche, has a different metabolism, and likely very diverse habits and behaviors.

[zealous ravine]

See the issue is, even though it does make a lot of sense for spino to have lips, there are some traits that argue against it. Namely, there’s some evidence to suggest the teeth would interlock, which would seem to indicate liplessness. But we don’t have enough evidence either way rn

[drowsy venture]

Thank you for answering my question. What is its hunting style "surprise attacks" when it came to using its padded feet for getting close to its prey and then going in for the kill? Similar to how crocodiles and alligators would jump out of the water catching any land animal close to it?

[little mauve]

Thats much more speculative but in general predators do favor ambush

[drowsy venture]

Thank you so much for answering! My next question is that are Reptiles (birds, dinosaurs, and modern day reptiles) much more adaptable, diverse, and hardy than mammals?

[queen oar]

What if we gave beaks to Spinosaurs?

[drowsy venture]

Call me stupid but I have a conspiracy theory that spinosaurus could be a chimera (its fossils).

[little mauve]

No problem, the only part of your question that I feel can be answered objectively is diversity and yes reptiles and birds are significantly more diverse than mammals

Together its like 20,000+ species versus just under 7,000

[balmy oyster]

They’re more diverse, but adaptability depends on the species itself and isn’t something one clade is better at than another

[zealous ravine]

You’re not the first to suggest this but the idea’s been thoroughly debunked, it’s definitely not a chimera

[balmy oyster]

Some reptiles are hardier and more adaptable than some mammals, but some mammals are hardier and more adaptable than some reptiles

[drowsy venture]

Makes sense. Mammals have been suffering more loss during this 6th mass extinction event.

[drowsy venture]

Could it have had a similar life style to a monitor lizard? Monitor lizards can swim and are good at it but they also don’t have any interlocking teeth? Maybe it could’ve just adapted a similar life to a crane

[balmy oyster]

Mirabilis & non-spinosaurine spinosaurids? Sure

Kem-kem spinosaurus? Not a chance.

[little mauve]

Thats not why they're less diverse. Mammals are actually the second most diversifying group after birds over the last hundred million years or so. Birds are where the real diversity lies in that count. Reptiles are so diverse because they occupy mostly small bodied niches.

[drowsy venture]

Spino could have had a hippo like life style

[balmy oyster]

YES

No more “croc or crane” propaganda…enough is enough sereno and ibraham…

[craggy trench]

heard it here first folks spino goes onto land at night and eats plants

[balmy oyster]

It ate the permian fruits that everyone conveniently ignored

[drowsy venture]

So what makes birds more adaptable and overall better to the point where they can exist in every continent.

[queen oar]

I mean, it could eat fruits potentially, no?

[balmy oyster]

Flight?

Turns out flying is really good at getting you places and starting new populations. It’s why a big chunk of mammal species are just bats.

[little mauve]

Flight helps a lot with dispersal, small body masses, the beak is a highly adaptable structure

[craggy trench]

as much any carnivore prob could if they wanted

[drowsy venture]

Don’t forget how fast their gestation is compared to mammals.

[pine hatch]

I got one tiny question guys

[queen oar]

Would YOU eat fruits?

[drowsy venture]

Parrots can eat small chunks of meat if they wanted to. They’re omnivores

[pine hatch]

Have yous got a favourite dinosaur

[drowsy venture]

Mirabilis and Eoraptor

[balmy oyster]

Tyrannosaurus. It is the coolest thing ever. I will die on this hill.

[paper parcel]

G R O K

[pine hatch]

I like the saurophaganax

[craggy trench]

Tyrannosaurus my beloved

[drowsy venture]

I remember someone saying that an African Bush Elephant can defeat a Tyrannosaur. Is that true?

[craggy trench]

ah allosaurus anax
good choice

[craggy trench]

I mean i dont see why rext couldnt
hes not ultra killing machine and I'm not gonna start a power scaling vs mammal discussion but
its possible

but rex didnt live with elephants and ive versa so it doesnt really matter if one wins or not
separated by so much time

[stiff osprey]

Killing an elephant would be pretty easy for a rex, it is just a less well-armed Triceratops. Meanwhile elephants have never evolved to defend themselves against predators their own size

[drowsy venture]

I remember hearing a take where someone said a jaguar would be able to kill an allosaurus

[paper parcel]

Allosaurus is peak af

[drowsy venture]

I never liked powerscalers among the palaeontology community.

Their logic kinda reminds me of this meme

[paper parcel]

Btw theres a evil dinosaur that existed and still does in the hearts of men.

[thorn grove]

I've seen people claim they could kill Tyrannosaurus

[stiff osprey]

I could kill Tyrannosaurus. if it had just hatched a minute ago

Well physically i could kill it, but emotionally i'd be devastated, so maybe not

[drowsy venture]

Just because it was as smart as a crocodile doesn’t mean it would lose to a predator that can hunt crocodiles

[paper parcel]

Not exactly related but i think sauropods are my spirit animal because I keep having dreams where I turn into them 0_o

[stiff osprey]

never dreamed i was a dinosaur but i once dreamed i was at a conference where they showed complete brazilian sauropod skeletons and was upset when I woke up and they didn't exist

[drowsy venture]

Drink the egg raw

Dinosaur meat would taste horrible though

[stiff osprey]

from carnivores yeah but farmed oviraptorosaur or hypsilophodont would probably be good

[paper parcel]

farmed sauropods

[left shard]

Do we have anything on pachycephalosaurus movement, and what exactly it could do with its potential ramming, and could they run fast to say outrun animals like nanotyrannus?

[undone rapids]

Pretty unlikely on the outrunning nanos part, nanos are so far the most running big meat eaters that have ever run.

[paper parcel]

Important question, is this a accurate depiction of bashanosaurus

[left shard]

More important question, can I please hug it

[frail jolt]

well its minecraft so... but for the mod that it uses ya. love thgis mod

[trim moth]

Wait whats the mod? I havent seen it before

[frail jolt]

prehistoric fauna, its peak

[trim moth]

Ahhh, so I’ve heard of it then
My pc just cant run it, rip

[frail jolt]

sry brotatochip

[runic heart]

Who is this guy.

[charred hearth]

has anyone shown this yet? https://www.youtube.com/watch?v=kspTTAj-b3I

[runic heart]

Some kind of pseudosuchian. Saurosuchus?

[charred hearth]

@hallow spear have you seen this paper yet? https://x.com/JamaleIjouiher/status/2028098586664218665

Jamale Ijouiher (@JamaleIjouiher)

New paper out on #dacentrurine #stegosaurs from #America. Showing both a wider distribution & greater diversity than previously thought. With a likely African origin for this group followed by migrations into North America and #Europe.

[kind totem]

realistic interaction between carcha and spino possible

[balmy oyster]

Is this AI…

Why am I asking this the spinosaurus is half croc and the “carcharodontosaurus” is just PhP rex but it went on a diet.

[kind totem]

no it isnt ai its 3d animation from primeval planet

the dudes work is amazing
