[hardy sentinel]

Did ancient Wasps have stronger stingers to pierce dinosaur scales? Is there a way of knowing and if they did not have stronger stingers, what stopped big herbivorous dinosaurs from breaking into a hive without reprocussion?

I know this may seem like a dumb question, but I am genuinely curious

[hallow spear]

It’s Lishulong, Yunnanosaurus and Plateo as top 3 in that order

[frigid delta]

besides, weren't Becklespinax an Altispinax synonym?

*Altispinax

[tawdry lintel]

There s a lot of confusion about this whenever I search about it, forums and so on portrays them as different and evn adding others, but I forgot the names, but they actually are the same ?

[frigid delta]

more like Beckle is Alti's old name
so yeah, same guy
Beckle = Alti

[tawdry lintel]

Ohhh

[short river]

If they're synonymous, would it not still be Beckle*?

Hate autocorrect

Or was it a rename rather then the two being classified as the same creature?

[frigid delta]

idk abt that
i only remember that Beckle = Alti
not sure abt the renaming/reclassification
-# this is all Chaos Theory's fault for naming them Becklespinax instead of Altispinax

[short river]

I'm only asking because usually the older name is the one it takes, so it seems off for it to take the newer one

[tawdry lintel]

I also would like to know how accurate is the Jurassic World despiction

[frigid delta]

eugh lipless

[flat pond]

I believe that Altispinax is the older of the two names, this was also made a debate with the Fossil Fighters community as Spinax was going through this ordeal. To the point in which the last game called it Beckles, though now we know it is Altispinax and the original name, Spinax should be used for any future games.

Also someone please give me my Fossil Fighters remake, the guy who does these models makes them so good without making the lose their designs

[frigid delta]

we need fossil fighters that have accurate dinos
Fossil Fighters remastered 2025

[flat pond]

Aye, as you can see, it can be done without losing the stylistic touch that they had in the games

And for anyone who’s asking about the top one, that’s Mapu but with more akin to its Frontier design. Honestly it looks really great the way the artist did it, tying it to its name sake (earth lizard) without changing the element it was given in the first place

[frigid delta]

does the game have...
have Giga 🥺

[flat pond]

Yeah

Fossil Fighters had a lot of prehistoric animals in the game that were really interesting and such. Here’s a list from the second game, Champions

https://fossilfighters.fandom.com/wiki/List_of_Vivosaurs_(Champions)

[warm saddle]

Ooo very cool

[floral ivy]

Indosauriscus

[drifting arch]

oh I love that art! What a gorgeous creature!

[idle storm]

I don't think there is any evidence to suggest this. Given the relative size difference, I think stinging wasps wouldn't have had issues targetting more senestive areas of the body (ie the face, areas of thinner skin around joints) or even just the spaces at the margin of where scales would meet. Given that dinosaur scales don't overlap, there would be small gaps between them where a sting could certainly irritate.

[steady rock]

Stegosaurus could only reach 6 km/h right?

[stable sun]

Elliot Giant is the largest, plus some larger than Płateo exist too

No, it's the unnamed Elliot Sauropodomorph

@drifting arch Lishulong also isn't the largest

Tyrannosaurus was heaviest long before Goliath

[stable sun]

Altispinax was named first

@frigid delta nope, Altispinax is the original name, Becklespinax was named only after some people misunderstood the paper describing Altispinax

I’ve tried that. I’m trying to find a Leaellynasaura lateral and dorsal but I literally can’t find it anywhere lol. Any discords you would suggest?

[opaque kayak]

99% of the time for more obscure dinos you won't find a dorsal, or even a good lateral. I think you probably would need to edit a preexisting dorsal to make one

It’s not against “physics” or anything

Already said that! Get faster!

[thorn grove]

depends on the sauropod but yea, but I've also seen people say that about large Hadrosaurs which I just find kinda baffling

[stiff osprey]

sauropods usually have the center of mass close to the hips, with the exception of like brachiosaurs but even a brachiosaur has a more balanced CoG than an elephant

[thorn grove]

that makes more sense considering elephants don't have much of a tail lol

[tiny holly]

It's more about how they have very spiky looking heads as juveniles, but as adults the spikes seem to be less extreme compared to their huge dome

[ionic crescent]

Unlikely, newest paper just used stygimoloch as name just to claim that there are enough differences not to lump it inside P. Wyomingensis

There's still a ton of similarities and even geographic zones to lump it inside pachycephalosaurus genus, tho ( genus ≠ species, ex: Triceratops horridus and Triceratops prorsus, or the multiple Pachyrhinosaurus)

[white inlet]

Alr dino nerds could someone find out how fast Daspletosaurus could run? Also I'd need it's weight

[white inlet]

Your a star :) I'm needing stuff for my video

1.1ton 39mph
How would one convert that to 3.5ton dasp running speed? Should I just estimate it, by being slower maybe at 34mph or less?

[scenic flame]

Alioramus~ (only two specimens which are juveniles)
Allosaurus
Amargasaurus~ (the genus Amargatitanis was lumped into Amargasaurus about a year ago, though it's generally claimed to be larger by how much isn't certain)
Camptosaurus
Ceratosaurus
Concaveantor
Daspletosaurus
Deinocheirus
Deinonychus
Iguanodon
Pycnonemosaurus~ (only one specimen which is a sub-adult)
Metriacanthosaurus
Miragaia
Rhamphorhyncus
Struthiomimus
Suchomimus
Tyrannosaurus

All of these are accurate or close enough to where imo it'd be kinda pretentious to call them oversized (under sizing imo isn't nearly as bad)

[white inlet]

I used dasp as its close to what I need

[calm agate]

Worth noting those speeds are km/h not mp/h, so the Daspletosaurus in the chart is going at 21.6 miles per hour not 34. The Das there is also 2.7 tonnes not 1.1

[white inlet]

AH DAMMIT

[white inlet]

This information is very helpful thank you excuse my dumb self you may have just saved the video lol

[hallow spear]

Unknown considering all estimates are based on wonky and inconsistent measurements of the limbs and based on a formula not built for ornithischians. once apex is described we will have a better estimate for how fast Adult Stegosaurus was moving at

[steady rock]

@sullen cairn did you ever figure out how amargatitanis was smaller then amarga?

[sullen cairn]

Kinda depends on which measurements you use
But regardless amargatitanis is separate from amargasaurus in like any and all formal publications

[steady rock]

If it was added to amargasaurus, what would the size increase be?

[sullen cairn]

Slightly larger at best
Forgot the specific numbers tho

[brave nova]

I wouldn’t really say Rex is that accurately sized from the looks of it it’s around 15m long and quite abit taller

[idle storm]

Because there's no set criteria for what "makes something" a genus, if *Stygimoloch *turns out to be distinct, and it doesn't mess with the monophyly of Pachycephalosaurus, it makes sense to retain it as *Styigimoloch *to preserve the continuity of the literature.

[ionic crescent]

Still unlikely, the morphological differences are so little, the geographical distribution matches entirely and the time gap between each other is extremely close (geologically speaking) that It can fall under anagenesis (unlike Edmontosaurus annectens and regalis which had a very massive geological gap)

Also let's be honest, people just want Stygimoloch just like Saurophaganax, because the name rocks lol

[scenic flame]

it's far from 15 meters

[stable sun]

Ye

[brave nova]

I’ll check it again when I’m home but I was told around there

[scenic flame]

I know it's size but I'm pretty sure I'd be breaking NDA as things are rn to give any specifics

[brave nova]

NDA?

[scenic flame]

previously I would've agreed but with specimens like Cope and Goliath it's not as oversized as before

[ionic crescent]

Easy, it's been confirmed laten to be around 5-6 meters long

One rex is as long as 3-4 latens one after each other, EZ

[brave nova]

The way I’ve looked at it is that pt Rex is 12.4m long and then pot rex is a decent bit longer and taller than it

[scenic flame]

not enough so to be 15 meters

[idle storm]

Like I said, there is not criterion defining what degree of difference is necessary to make something a new genus (and I won't go into my thoughts on anagenesis here). The only critical factor when making that decision is retaining monophyly (and even some authors disagree about that, but they are a minority). If *Stygimoloch spinifer *is diagnosable as a distinct species from Pachycephalosaurus wyomingensis, then it is a valid interpretation to retain it as a distinct genus, provided it doesn't sit phylogenetically between P. wyomingensis and another species of Pachycephalosaurus (which we currently have no evidence to suggest). Because genera don't really have a biologic reality, in this case it isn't about liking one name or the other, it's about making a decision that causes the least amount of confusion. Given the prior usage of Stygimoloch in the literature, that's a good reason to retain the name if there isn't necessary cause to dump it.

[compact leaf]

genus does have biological reality though? like especially in modern times when genetic testing is possible we do have a concept of what encompasses a genus and species

and in fossils species it isn’t internally consistent between some groups but there is a genus and species concept based on derived characters, the differences may be enough to diagnose it as another species of pachycephalosaurus but at the current moment it doesn’t seem distinct enough to be a different genus

[idle storm]

There is no such thing as a genus concept

Species are biological entities that, while often difficult to pin down, can be conceptualized, defined, and distinguished. Genera happen to be clades that cannot contain other genera, and therefore are by necessity the "next step" up from species. But there are no biological criteria that define a genus, there isn't a degree of difference (either morphologic or molecular) that we use to draw the line between one genus and another.

It's for that reason that we have genera like Varanus with ~80 species on multiple continents and Heloderma with ~5 species restricted to North and Central America, or Crocidura with over 180 species.

[compact leaf]

there are definitely revisions necessary in places nobody would debate that, but there is a molecular distinction for genus I’m not gonna argue about it I deal with it every day (especially if you’re getting into bacteria)

regardless of that though it’s a distinction we use with dinosaurs and if you’re going to ditch that distinction you may as well say all of them are subjective

[steady rock]

Can someone tell me what we're talking abt in a caveman language for simple minded people like myself?

[idle storm]

There are different sets of nomenclatural and philosophical guidelines for bacteria and multicellular Eukaryotes. I won't pretend to know the former, and if there is an agreed upon molecular distinction for bacterial genera that's cool! But I will reiterate that there is no such distinction between vertebrate genera. There is no agreed upon degree of molecular difference before we decide that something is a new genus. That is a phylogenetically informed decision.

And I'm not suggesting we ditch distinctions at all, in fact quite the opposite. But simultaneously we have to recognize that assigining a ranked label to any clade above the species level is a subjective decision. It's why rank-based taxonomy just doesn't work in the modern age, the implied equivalence that should exist between genus to genus, family to family, order to order, etc. just doesn't exist. But that's OK!

Let's use a different example, Tyrannosaurs, and I'm going to push it to the point of absurdity, but it's for good reason. For the sake of discussion I am using the Brusatte and Carr 2016 phylogeny. We agree that the tips of their tree are distinct species because they are diagnostically different from one another. But if one author decided "T. rex and Tarbosaurus aren't all that different, and called Tarbosaurus Tyrannosaurus bataar (which some authors do IRL), then that is not running afoul of any biologic realities, they are still sister species after all, it is only impacting the literature.

But we could take it further. Say another author has a looser sense of what a genus is and lumps Zhuchengtyrannus as T. magnus. Still all well and good because we haven't violated monophyly. Another author might even say, "look at how much variation there is in Varanus, compared to these animals. I think that the main difference in tyrannosaurines is between the Alioramines and the rest of the group, and it is sufficient to lump Daspletosaurus, Lythronax, Teratophoneus, and Nanuqsaurus all into Tyrannosaurs. Given how morphologically variable modern genera can be, this frankly wouldn't be an absurd group to make. But clearly it would have terrible consequences for engaging with the historical literature.

[steady rock]

Would Sauropods theoretically have the largest eggs?

[warped peak]

No I do

[idle storm]

Among non-avian dinosaurs the largest, well attributed fossil eggs are attributed to sauropods, but some theropod eggs are also quite large (~2ft long), but more elongate than spherical. The largest known eggs however are attributable to the recently extinct Elephant bird.

However, the large soft shelled egg from Antarctica (Antarcticoolithus) is larger than known fossil dinosaur eggs (and only slightly smaller than elephant bird eggs). It was originally attributed to a mosasaur, however the revelation that many dinosaurs laid soft-shelled eggs means that it is very possible (if not likely) that a dinosaur laid this egg. If that is the case, then conceivably some kind of non-avian dinosaur may have laid soft shelled eggs larger than elephant birds, however we have no direct evidence of this.

[full anvil]

Nah bro, wth is this

[manic grail]

We cant know for sure i guess

[full anvil]

I mean, I guess yeah but
That just doesn't look right to me. I don't know

[warped peak]

Didn't you know? Their necks were too long and cumbersome to reach the ground so they used their mighty trunks to help forage through grassing and ground clutter

[tulip dove]

Fairly sure it has been debunked a while ago
There really wouldn't have been a need for a trunk when you already have a very long neck

[full anvil]

That's what I'm thinking, makes no sense
Then again, idk when that book was made

[scenic flame]

https://tenor.com/view/aku-unamused-samurai-jack-unimpressed-gif-8301624

[scenic flame]

We do know that it didn't have them actually, it was a short sighted theory that ignores soft tissue correlates that can be observed on the bones, which do not support any kind of trunk

[full anvil]

Yeah. I was looking at the books my library has and the most up to date book is from 2006. I wish I could get some more up to date books without going online to find them

[idle storm]

The notion of trunked sauropods popped up a few times in the late 70s and early 80s, but even in their heyday they weren't taken very seriously. Bakker explored them mostly out of a fun "what-if" sort of vibe pursuant to his sense that advanced sauropods had some kind of modified lip tissue. But ultimately a trunk requires the presence of facial muscles that no reptile has.

[steady rock]

thoughts on lipped spinosaurus?

[idle storm]

I don't have strong thoughts on it. I think reduced or absent lips at the terminal rosette makes sense, but I don't think its strictly necessary. Maybe they didn't have them at all, that also wouldn't be out of the question.

[steady rock]

would spino have any need to loose them? i remember falcon stating that we started out with lips or something like that so it had to evolve to get rid of them

[tulip dove]

I like lipped Spinosaurids, but I'm not against lipless ones either

[idle storm]

The way the teeth interact with one another at the tip of the snout presents more opportunities than normal for lips to get snagged. I don't think that means they had to lose them, but I could see it happening.

[full anvil]

No real thoughts, I just go with whatever is the most commonly thought for something like that

What did yall think of prehistoric planet?

[manic holly]

https://tenor.com/view/me-atrapaste-es-cine-its-cinema-cinema-esto-es-cine-gif-17729711691959966457

[full anvil]

In this case. I definitely like the no lips more

[manic holly]

Yeah I always liked exposed teeth spino, feels like something spino would have

[brave nova]

Out of all dinosaurs that likely have lips spino and spinosaurids in general likely didn’t

[tough parcel]

Impossible because the splay on the snout of Spinosaurus (and the accompanying tooth size) would mean the lips would need to attach lower than any known animal

[steady rock]

so it cant have had lips??

[tough parcel]

Red is lips
Blue is gums/empty space

[manic holly]

So it IS more likely spino had exposed teeth?

they are still cats they just aren’t big cats, the big cats are genus Panthera but true cats are all of felidae

[hardy sentinel]

cool, you've just demoted another group from true cats. You have made your image even more untrue /j

[compact leaf]

huh?

[hardy sentinel]

wait nvm I am dumb. Disregard literally everything

I dunno how I know more about prehistoric animal phylogenetics rather than modern animal phylogenetics

[compact leaf]

modern has had a lot of shifts over time it’s hard to keep track of sometimes

[hardy sentinel]

So do prehistoric animals, if not more. Segnosaurids (in Therizinosauria) were once considered to be late surviving basal sauropodomorphs until the 90s 😭

[drifting arch]

That’s what I thought as well

[warped peak]

I'm just imagining it whispering in my ear and I hate it

Why does the 1850s Iggy have a thumb spike? The thumb was thought to be the horn. This is 1850s Iggy

[frigid delta]

b-but the horn... is already over there...
🥺

[hallow spear]

Yes it is, there are 3 seperate tracks of supposed stegosaurs from Australia, @serene moat the garabina one probably isn’t a stegosaur though

[hallow spear]

It is too slow yes

[wind prairie]

why should they not be considered cats, they're still felids

[warped peak]

tbh wouldn't it be more accurate to consider Big Cats not actually the true cats

Considering we typically refer to House Cats as "Cats" predominantly

[thorn grove]

tbf felinae and pantherinae are closer to each other than to machairodontinae, at least from a cursory glance on wikipedia, so you could consider both cats while excluding machairodonts

[hardy sentinel]

They lack a long tail, the detary doesn't look much like a cats, and they don't really share that much in common with cats in my opinion

[halcyon cobalt]

they kitty if they fluffy and have claws and

[hardy sentinel]

dogs, bears, pinnepeds, any weasel, hyenas, etc

I can see the simularities between the Machairodonts and the modern felids, but aside from that they are pretty different. Even the baby looks highly different, and it really puts it into perspective when you realize that Machairodonts and modern felids aren't all that close, just each other's closest relatives

[hallow spear]

[tough parcel]

Minus the humanoid face, it makes sense considering the history of SCP-3199 (iirc hatching from chicken eggs/chicken-like eggs?), its hunched over back, and two fingers

Though the SCP was mainly meant as a jab towards "Behold, a man" (I think)

[steady rock]

Ooh ok

[hardy sentinel]

Do you guys reckon that Nanotyrannus and/or juvenile tyrannosaurus could have sometimes been waders at times? Their build reminds me of some wading birds with the proportionally long legs and thin snout

I dunno if this is a dumb hypothesis, also I know the art isn't spot on but I hope it gets the point across

[halcyon cobalt]

don’t see why not

[outer tusk]

maybe but most likely wouldn't be very common for them as they're most stuided to hunting simialr fast animals due to their long legs

[tulip gyro]

https://cdn.discordapp.com/attachments/801248420487626752/1328535651850784869/lv_0_20250113222611.gif

[hardy sentinel]

I'm not saying it was a primary thing, but when fleet footed prey wasn't available do you think they would have gone to wading for fish if necessary?

[outer tusk]

nah

[hardy sentinel]

Or it could be sensors like crocodillians have, whiskers would need to be really advanced feathers or a new kind of adapted scale for something like whiskers to happen

Well, why would a wading animal have whiskers instead of pit sensors? Whiskers wouldn't help with finding fish as much as sensors would. You gotta take lifestyle into account

Also, Megalosauroids aren't exactly known for having feathering, quite the opposite actually. It's unlikely that Spinosaurus (a Megalosaurid) face the selective pressures to re-activate the gene for feathers on their face specifically, have them adapt into feelers similar to cat hairs, and then live a Semi-Aquatic lifestyle where they would serve no use

The reasons the majority of mammals have whiskers is due to our ancestral nocturnal lifestyle, which whiskers assisted in for getting around without bumping into stuff

Didn't know if you were asking a question, doing a fun hypothetical, or arguing a point, my bad

[balmy oyster]

Let’s make a rex adorable by adding 2 tons of feathering to it on spots that didn’t preserve skin impressions, and give it big ol’ spikes cause that’d cool!

[hardy sentinel]

Well, for the hypothesis part it is very unlikely because it would require a short amount of time to convergently evolve a very specific trait in a very specific situation that the animals clearly didn't go through.

For the other part it is a fun little thing

I reckon a better animal to look at for such a hypothesis would be small Ornithopods and Marginocephalians

That's understandable, people in this channel usually expect questions/debates rather than fun whimsy I guess, if you wanna do a hypothetical like this though, I'd recommend looking at neo ornithischia,

that group has small Ornithopods and Marginocephalians with evidence of an ancestor with feathering, which may have lived similar lives to earlier mammals. So for the whiskered bois you could look at adding whiskers onto some of those tiny guys

[balmy oyster]

That’s because there have been many like you, except…they’re not whimsy, silly, or a little mischievous. They genuinely believe it.

[hardy sentinel]

You could also be under the assumption that since feathers are ancestral to Avemetatarsalia (Pterosaurs and Dinosaurs) as a whole, you could maybe look at putting whisker-like feathers on Liaoningosaurus (a small suspected to be aquatic Ankylosaurine)

https://en.m.wikipedia.org/wiki/Liaoningosaurus

[balmy oyster]

Anky does not really need whiskers I’m ngl

isn't anky 4 tons 🤓

why would ankylosaurs/nodosaurs be eating insects 😭

[compact leaf]

should also point out that semi aquatic liaoningosaurus has never had a ton of backing, it doesn’t have any real adaptations for it and the fish probably just died in its body cavity after it was dead

[halcyon cobalt]

I also love making things up sometimes

[hardy sentinel]

I imagine that people who speak Latin and English fluently but don't know about dinosaurs would have strokes if they heard the average path of titans player communicating with another path of titans player about the game

"So yeah this Tyrant killed this hard and then this dawn came and killed my king instead of the Tyrant that killed the hard!" is probably how they'd perceive the sentence "So yeah this Tyranno killed this Pachy and then this Eo came and killed my Rex instead of the Tyranno that killed the Pachy!"

Is this store legit? I kinda want to buy this raptor tooth.. https://www.fossilera.com/fossils/serrated-72-raptor-tooth-real-dinosaur-tooth--162

[brave nova]

It’s still abit bigger than both especially height wise, length wise it’s around 1 m longer than Goliath and then over 1m longer than cope

[fossil ingot]

Goliath is 13.1m, POT Rex is like 13.5m so its not by Much
PT Rex is 12.4m and Missing Leg Cartilage

@bitter quest thats why I said its 12.4m, and Its missing Leg Cartilage cause its using the Skeletal Version that doesn't has Leg Cartilage

[bitter quest]

Pt rex is size of sue

Since that's what pt based it of

[inland silo]

Honestly when I saw that sub I was like "why does it got a tumor on the back of its head" 😭

[brave nova]

Pot Rex does seem to be more likely 14m but it’s 13.5-14m since u can’t really get an exact estimate, since it’s a decent bit longer than pt giga being 13m. But then as I said height wise it’s likely a lot taller can’t really get height estimates unless u put a keleken next to it and ig scale it off that

Spider with gills?

[warped peak]

Mimetaster, one of a family of basal arthropods. It's preserved covered with living sponge and various endobionts, implying it was like a teeny little Torterra covered in life, as this is seen on almost all 100 specimens

[tough parcel]

Provide his current link because I didn't care enough to search through from:Dan has: Giganotosaurus

[brave nova]

There isn’t an updated version of it just all the weights are wrong.
for biggest these are their weights apart from Rex which is 12900kg using Goliath

Rex got 2 bigger specimens since that released. Giga got some changes which made it abit bigger and spinos weight range goes up to 8.5t

[zealous ravine]

Worth noting those giga and rex specimens are very tenuous and may be smaller

[brave nova]

Same could be said for spino. But copes even more reliable than both big spino and big giga. But then if u wanna use holotype giga it’s 8.5t

[opaque kayak]

I actually have this one below as well, with updated skeletals from the same author (btw captions are not by me)

The spino should be 8.5 tons, giga is scaled to the holotype here, so 8.6 tons and rex is scotty, so 10.4 tons.

[brave nova]

Holotype giga is 8.5t and then u can also say Scotty is 10.5t but that’s getting into all the specifics

[opaque kayak]

Yeah, well it's down to the decimals. These aren't to represent the biggest specimens, just whatever dan folkes used originally

[brave nova]

Also with dans spino im confused on y it has the rounded sail. I thought we knew that it wasn’t rounded and whatever shape it is on randoms (I forgot what the shape is called)

[remote shadow]

I mean isn’t Sue also more than 9t?

Thinking in lines of mostly complete finds

[opaque kayak]

It's based on the neotype + the huge dentary, so he was taking libertys. TBF I would also agree with the sail prob being M shaped

[brave nova]

Sues 9.7-10.3t. Man I hate the chat cd sometimes

[brave nova]

I can’t remember which specimen actually shows the M shape sail. (Well it’s either neotype or the one with the paddle tail lol) so ima guess is that one

There was a comparison with the 4 spino specimens (excluding holotype) but I cannot find it

[opaque kayak]

It's the holotype, and nothing else really preserves the sail shape well

[deft stump]

Does anyone feel like new rex is kinda... Skinny? Just in general. Like it was slimmed down. It's skull looks skinny, Imo It looks like tarbosaurus. I still love it, tho. Just want a bulkier rex.

Also feels a tiny bit like the hips are too slim, the tail slightly tapers at the base, then thickens.

The old rex seemed more proportionally correct from the shoulders down, but I like the new ones skull more.

[halcyon cobalt]

probably based on the slimmer specimens and not the rotund behemoths like sue

[halcyon cobalt]

maybe it’s just because i hate fun and joy but those memes about spinosaurus being nerfed into a bacteria or something are really annoying

[stable sun]

true

[tulip dove]

They are
People calling one of the most unique theropod known to science nerfed and boring because it isn't the same early 2000s giant dinosaur slayer

Now it's a really fascinating animal with a unique appearance instead of an oversized Baryonyx with a sail slapped on its back

[sharp dragon]

"When they gonna nerf spino next" Ah yes, because paleontologists clearly just say random malarky about a dinosaur without any clear reason, not like the spinosaurus has remained a highly incomplete animal in the fossil record and many parts of its lifestyle and general ecology are shrouded in mystery due to a lack of fossils... Good heavens.

Memes like that seem to invalidate the tremendous work paleontologists actually put into their line of work. It's downright disrespectful to imply that these workers just make stuff up for the hell of it.

James Napoli from the Skeleton Crew YT channel explained it well in their video covering the JWE2 spinosaurus.

[tulip dove]

Dinosaurs fighting each other is also cool, yeah but thinking that how capable a dinosaur or any animal was fighting against animals it never met matters is just dumb thinking
Why does it matter whether Spinosaurus or Tyrannosaurus won

[sharp dragon]

Two animals from distinct environments, time periods, niches, family trees, and morphological differences had a major power difference between them in pure combat? Preposterous!

[tulip dove]

Crazy even

[sharp dragon]

Funnily enough, some of the complaints about the new Jurassic movie's spinosaurus is that it looks like a baryonyx with a sail.
I can tell you that, no it doesn't, it actually has a (somewhat) spinosaurus specific skull shape, and the body anatomy is roughly there, paddle tail and all.

Not like the original one was quite literally a baryonyx with a sail or anything.

[manic grail]

Maybe thats why they're called "memes". Just saying

[drifting arch]

Such a great show, love the models

[fallow stirrup]

Is it true ceratosaurus was a strong swimmer?

[hardy sentinel]

Maybe, it was suggested that they could hunt aquatic prey better than any other theropod in the morrison so I guess in relation to the other theropods, sure

They did live in more wetland enviorments though, which could suggest they could swim and hunt in the water, but I don't reckon there is direct evidence to support it

[fluid inlet]

[hardy sentinel]

You know what, after being re-exposed to the semi-aquatic Ceratosaurus theory, ima do some messing around on PoT and The Isle to see how they do as riverside hunters

[sudden wind]

What is the "it lived in more wetland environments" based on ?

[light osprey]

I feel like I’ve heard ‘it lived in more arid environments’ and ‘it lived in wetter environments’ for the ceratus

[fallow stirrup]

Apparently crocodiles where a big part of its diet

[tacit pine]

Just ignore them 😭 , its pretty clear its rage bait atp

[tough parcel]

Where is the proof of this?

AFAIK the only evidence of Cerato's semi-aquatic nature is a "flat, flexible tail", being smaller than Allosaurus/Torvosaurus, and being found in a wetter environment

None of these correlate directly to a semi-aquatic lifestyle

[fallow stirrup]

Not sure I just remember hearing that somewhere

[alpine island]

There’s a like 20 year old paper by Bakker that proposed more water inclined Cerato

RE: spino memes, it really ain't that deep. It's pretty common of a joke for people to use game terms for real life by calling things op and nerfed. it's jokes. whether they're funny or not is subjective.

just really not something to get too upset about is all im saying

On my end, it's not so much that it's "deep", it's just repetitive

[rancid dove]

Guys, is it me or do I have an impression that the cera is a bit weird?

look prior exctinction,its skeleton corresponds exactly to the original(skull/bones)

[ripe stirrup]

Prior exrtincion mentioned???

[rancid dove]

You mean I didn't mention the author?

[ripe stirrup]

No I mean that no one ever talks about prior extincion and it's a very underrated game, so it's good to see someone who knows it

[fossil ingot]

What happened to Bro

[rancid dove]

yup is a nice game,but I'm talking about their model, it fits perfectly with the skeleton and I'm a little lost with the official one

[steady rock]

pug

[ripe stirrup]

Yes, I love prior extincion just because of that lol, they make dinosaurs so accurate

[fossil ingot]

Now he looks better

[rancid dove]

I really like their ceratosaurus, with the skil you can an solo allosaurus fragilis :p

[tough parcel]

It's not underrated, it's just bad 💔

Anyways, iirc the Cerato model was originally done via Jiggy eyeballing references at the time (Scott Hartman's Ceratosaurus)

The recent Ceratosaurus model "TLC" was predominantly model edits and not an actual remodel so they still had to work with the proportions in the original @rancid dove

[fossil ingot]

Thats a Rather Chunk Cera

[tough parcel]

Ohh @hallow spear please overlay the PE Cerato on the skeletal promptly thank you 🤗

[rancid dove]

I see....., but then you think that later they will remodel it?

[ripe stirrup]

It is underrated, you know, it's a roblox game, of course it's not gonna be the best dinosaur game ever known but just look at the screenshots mobi posted abt the prior cerato, they're VERY good and have VERY good graphics for being a roblox game

[fossil ingot]

Graphics doesn't make a Game good tho.
You need more than that

[rancid dove]

when you compare it to the one of prior exction it looks less threatening💀

[tough parcel]

What Srumis said

The graphics can be pretty and all but when the rubberbanding is so bad that I can get shadow-sniped by a Tarbo from 50 yards away, it significantly downgrades your game's rating

[steady rock]

prior extinction when you have to pay 100 dollars to play rex ( iirc )

[ripe stirrup]

They also have a lot of more mechanics than pot does, for example when ur dino is cold you can cuddle up with another dino and you won't be cold anymore, ik prior isn't really good but it's a freaking roblox game what do you expect?

[fossil ingot]

POT Cera also uses Hartman's Cera as a Reference not Random's(This is Hartman's Cera edited to be on a more Neutral Posture)

[ripe stirrup]

Fr

[tough parcel]

Having more mechanics also does not make a game good and when the temperature system can be such a pain that you'll keel over if you're standing in the sun a little too long, that's not good

[rancid dove]

The Sleep System, Stay Clean, The Mix Pack and more

[fossil ingot]

Quality≠Quantity tho.
I have seen ppl talk about Prior Extinction
Graphic Wise is Great, but its Lacking Gameplay wise
And why yes there is the excuse that "its a Roblox game"
Doesn't mean the game doesn't has alot and worse gameplay error than POT does

[tough parcel]

Evidence that one should aim for refined mechanics over more mechanics...?

[ripe stirrup]

I'm not saying that yall aren't right, I'm just saying that it's pretty good for being a roblox game. I don't even play it that often as I play pot

[frigid delta]

Dandy's World better

[fossil ingot]

If Graphics was the reason a game was good
Evrima will be like
Top #1, and we all know Evrima can look as Good as it does but that won't save it

[ripe stirrup]

I've never said that it's good just for the graphics, it was an example

[jagged trellis]

prior is not good
PoT is also not good, just not as much seeing you can actually access the roster consistently and not implode because you got cold
anyways PoT cera matches the skeletons of ceratosaurus fairly well, its just the neck is held up alot and like a smidge off on the nose tip iirc

[fossil ingot]

I mean.
Theres Roblox game that they not look as good as Prior Extinction
But are much better gameplay wise.
Been a Roblox game shouldn't limit you to Proper Gameplay
Specially when they are games that show proper gameplay can be done
So its not an Excuse
Prior is more a game to look than to play

[tough parcel]

Society when Evrima is actually epic (minus its optimization but like skrill issue!!!)

[rancid dove]

even the eyes

[ripe stirrup]

This is true

[fossil ingot]

If Evrima had proper optimization(you need a Nasa PC to be stable)
It would be great
Cause it has Cool mechanics and Potential
But thats a Different Story

[ripe stirrup]

Anyways, question, since accurate dilophosaurus didn't have frills, it there any dino that had them?

[fossil ingot]

Ehhhh.
Tmk likely no
Iirc

[rancid dove]

like dilo polar xD

[halcyon cobalt]

triceratops

[steady rock]

do you guys think we'll ever discover another asian centrosaurine or chasmosaurine?

[ripe stirrup]

Those don't count those aren't frills 😔

[frigid delta]

then what is it?

[fossil ingot]

I Wish POT Makes Puru as a Future Playable.
So that they can downsize Sarco and then Upsize Puru so it can be the True Large Proper Croc

[jagged trellis]

the aisle: 13, paradym edition vs walkway of gargantuans with online coins
and no, the flap frills anyways, because they require alot of attachments to work and don't think we have many that match it

[ripe stirrup]

I meant frills that could close and open like the frilled lizards or the jp dilophosaurus

[rancid dove]

cretoxyrinha too i realy hop

I mean there is the megalodon which is already planned by other modder, but this shark it can be a good slot 4

[frigid delta]

why not Deinos?
ik they're the same weight but why caiman instead of alligator?
-# my opinion pls no angy

[tough parcel]

The only animal nowadays with such an adaptation is the frilled lizard and its skeleton does show the frill (as the flaps are anchored on the hyoid so it's well-developed)

No dinosaur we know of has this

[fossil ingot]

Cause Deino is alot more represented than Puru is
Puru is on Fewer games too
Plus Puru can properly High Walk

[jagged trellis]

don't frilled lizards have a absolutely jutting bit of bone on their jaws

[ripe stirrup]

Aw man I wish there was a dino like that

[frigid delta]

two underrated theropods that i finally remembered (poor guys)
how's Lythronax & Ekrixinatosaurus?

bro

[fossil ingot]

how much did nanotyrannus weigh?

[frigid delta]

what even the hell happened to Ceratops???

[tacit pine]

How much did majungasaurus weigh?

[thorn grove]

he died

[fossil ingot]

Around 1500kgs

[fossil ingot]

Prob like 500kgs or smth like that.
Not sure

[steady rock]

is that like, 1 ton?

[bitter quest]

Albertosaurus, appeared in more popular media and documentaries

[steady rock]

i mean, gorgo appears in wwd ( movie ) and march with dinosaurs
das appears in PoT, planet dinosaur

[fossil ingot]

1000kgs is 1 ton

[bitter quest]

And Albertosaurus in Jurassic Park/world games, primeval, the isle, walking with dinosaurs, etc

Basically the more well known stuff that makes up the dinosaur community

[fossil ingot]

Gorgo also appears in JP/JW Games tbf.
Anyways Alberto is just a Ugky weird fella

[bitter quest]

Well yes but Albert was first before gorgo in Jurassic

Not to mention mods for ark and soon path of titans. There's just more Alberto than gorgo

[steady rock]

okay i feel like, its between dasp or alberto

[bitter quest]

Those are the more popular ones but Alberto has more appearances in popular stuff still

Gorgo is the the least and Alberto the most while dasp the middle

[steady rock]

how far do you think PoT carries dasp in popularity?

[bitter quest]

Good amount

Plus Alberto in Jurassic fight club/ land before time

[fossil ingot]

Pretty Hard imo

[thorn grove]

alberto was also in prehistoric park during the deinosuchus episode

[jagged trellis]

like half of it

[wind prairie]

PoT gives dasp like 20% of its popularity at most
most of us remember it from dinosaur planet and dinosaur king

[bitter quest]

Which also Alberto appears in along with fossil fighters and Ubisoft battle of giant dinosaurs

[jagged trellis]

idk on dinosaur king
planet dinosaur for sure seeing that

[bitter quest]

But yeah Alberto low diff since how popular it is especially in games

Not to mention Alberto is the strongest out of the three in fossil fighters champions in competitive scene, and that game still popular to this day

The best dinosaur pokemon game we got

[steady rock]

what do you guys consider more popular, styraco or pachyrhino?

[bitter quest]

Pachyrhino; more appearances, more popular in games, and lastly in popular movies/documentaries

[steady rock]

@tough parcel do you still have that giant megalosaurus specimen?

[bitter quest]

Anyway I love this artwork. This was when Titanomachya was thought to be smaller

[rose gate]

https://youtu.be/gQIQRpuPDGc?si=4kJi7CCEQun4ORz_

Haven't watched it yet but I think hadrosaurs since how many there are and most common type of dinosaurs to find

[steady rock]

sauropods:

[fossil ingot]

[bitter quest]

True, not to mention in that game you get Alberto eariler compared to dasp and gorgo

[frigid delta]

Monoclonius = Centrosaurus, yes?
just like how Agathaumas = Triceratops?

[warm saddle]

yeah

[frigid delta]

bet this will be Rex in 2277

[frigid delta]

‎
wait where's its size

[outer tusk]

Titano is much shorter than that, it really isn't much taller or bigger than carno

[potent bobcat]

Ooh, could make for another Reasonably Sized Sauropod (tm)

[fluid inlet]

Nobody wants a small sauropod in path of titans, go play amarg.

[cloud dagger]

How do you know that

[potent bobcat]

He doesn't, there's a Euhelopus upcoming, as well as a Bajada

[outer tusk]

Euhelopus, I woudln't really call "small" even for a sauropod

[alpine island]

Euhelopus is a pretty large taxon iirc

[outer tusk]

8 tonnes

[fluid inlet]

I was referring to Titanomachya it would be small in the game.

[outer tusk]

I was referring to Asperger comment

[bitter quest]

Basically around double

[bitter quest]

It got upsized not as short it was once thought

[outer tusk]

where

[bitter quest]

Old left, new right

[fluid inlet]

Would pterosaurs ( the smaller ones) ride on big animals similar to little birds do today with like hippos and rhinos for example? I know in reality there is no proof of it. I’d reckon they would.

[cloud breach]

For the smaller ones I dont see why not, probably something like WWD

[balmy oyster]

I don’t understand how the guy got 7 tons in weight from something that would be a little over 3t at the largest

[sullen cairn]

cause thats the long bone circumference allometry estimate from the description

[full anvil]

What it the most up to date spino appearance?

[scenic flame]

this animal brings me great rage

[opaque kayak]

why tho hmmmm

[scenic flame]

instead of just having longer arms relative to the legs to angle the animal more upright, like any other civilized sauropod, it just made the chest massively taller while keeping the limbs of equal length

[stable sun]

No, Euhelopus is ~3.5-4 t, not 8 t

[steady rock]

whats the top 3 most popular ceratopsians would you guys say?

[scenic flame]

triceratops first, Pachyrhinosaurus second, third I'm not so sure

[steady rock]

styraco? maybe sino? centro?

[native kindle]

protoceratops

[steady rock]

oo true

[native kindle]

its appeared in both dinosaur planet and dinosaur revolution, and its a very popular museum piece while being in a fair few games

[low raven]

I’d say styraco for 3rd

[wind prairie]

1. trike, 2. styraco, and 3. prob proto or taco

[dire frost]

Trike, styraco, pachyrhino

And the next to runner ups for a top 5 list would by penta and taco

[junior dawn]

trike, styraco, pachyrhino

[manic grail]

Does anyone know when we will get to know more about that "scimitar spino" from niger

No and you won't get any

what specimen is that do you know

[hard kernel]

Quick question: was sucho fully terrestrial or did it swim a good bit

[brisk hound]

im not an expert but i would assume that it swam, but i dont think it was very good at diving though

[steady rock]

wading:

[brisk hound]

yeah thats the word

[hard kernel]

oh ok 🙂
Was talking about if it was fully terristial or semi aquatic for a bit. The arguement for it being terristial(hunting fish like a bear) was bone density,long legs,no dimples on the skull,more muscular jaws

[brisk hound]

thats a pretty likely theory, also my backer title got taken away for some reason

[steady rock]

yeah but then you come to realize you may not be appreciate what you use to have but you can appreciate what we have currently and that the people in the future can see what we're seeing rn

[frigid delta]

is Nedoceratops valid?

[warm saddle]

tmk yes

[sharp dragon]

That's right, didn't spinosaurus get longer legs? or am i insane as per the usual.

[warped peak]

Different species

[bitter quest]

Yes, it possibly grew bigger if it turns out triceratops 'albertensis' is a nedoceratops

[stable sun]

seems to be

[stable sun]

which is kinda based on nothing

[brave nova]

Between spinos legs and tail which one would it have been more likely to use to propel itself with in the water?

[sudden wind]

I imagine it paddled with its feet like a bird but also used it's tail sort of like how a lizard or crocodile does, so both.

[halcyon cobalt]

perhaps it would swallow water and quickly expel it from the nether regions, in a method similar to the propulsion of cephalopods

[sudden wind]

Like, iirc Spinosaurus wouldn't be very stable via swimming and I can't imagine the tail alone being enough to propel it.

[fluid inlet]

????

[tulip gyro]

hippo walk
-# jk

[sudden wind]

An terrestrial animal that reaches the bottom of a water hole do that so possible too.

I wish there were more studies about swimming locomotion in dinosaurs

[tulip gyro]

atleast for semi aquatic dinosaurs

was deinocheirus able to swim well?

[umbral kite]

how accurate are this fossil

[sudden wind]

I don't think it was to any extent aquatic. I suppose it would swim quite poorly.

[viral stump]

not like i'm an expert on swimming locomotion, but its build doesn't scream hydrodynamic to me. but animals can be surprising so shrug

[brave nova]

Both the tarbo and Rex are the most up to date ones

[umbral kite]

howd u knew they both werent tarbo

[brave nova]

Cause the 2nd one is much bigger and it’s sues skeletal

[fluid inlet]

Paleontologist stonks 🤓

[fossil ingot]

Likely None of those.
Prob Its Stan or smth else

[brave nova]

Ceras like 2m tall and 7m long. Allo Anax is like 4+ m tall and 11.7m long so who knows what they mean

pretty much any browns or reds work, maybe greens or deserty colours

[steady rock]

Tyrannotitan was rainbow

[warped peak]

Tarbo has multiple literal translations. Both "Alarming" and "Reverant" are valid, but Alarming tends to just imply fear instead of the "shock and awe" that the literal meaning is closer to. It's not that it's Alarming, it's that it's overwhelming

[pliant cedar]

i ssee

[remote shadow]

I wonder if it’s skull is correct in game to what is known of it currently

[tacit pine]

Gorgosaurus, dreadful lizard

[warped peak]

Thats kinda just average theropod name

[tacit pine]

Let me geuss, because it has a “lizard” or “saurus” 🙄

[pliant cedar]

then you get boring ones like 'alberta lizard'

[zealous ravine]

Achillobator goes hard, “Achilles hero”

[umbral kite]

i still have beff with tyrannotitans name

[outer tusk]

why

[umbral kite]

it still doesnt make sense to me

[outer tusk]

"Tyrant Titan of Chubut" doesn't make sense to you?

[undone rapids]

Its illegal for charcs to be tyrants

[velvet burrow]

One of the most futile things you can do in biology is trying to make sense of the names

[warped peak]

Scary Word + Saurus

[remote shadow]

Many of the names form that family are a bit try hardie tbf. It’s like they are the little brother trying to out cool the Tyrannosaurus

[bitter quest]

Lythronax

[thorn grove]

tbh Tyrannotitan sounds like a made up Dinosaur name

[frigid delta]

erm if Raptor where sickle toe claw

[ashen wedge]

Better yet, where it foot?

[warm saddle]

is pulmonoscorpius bigger than brontoscorpio

[sharp dragon]

wher dinsar.
Y itb hed

[warped peak]

It is not

The largest scorpion known is Praearcturus

[warm saddle]

ohhh cool

[hexed junco]

Thank you.

[frigid delta]

Jaekelopterus???

[warm saddle]

that's a eurypterid

[rose gate]

Is this accurate? 🤔

[warped peak]

Jaekelopterus is not a scorpions. Praearcturus is

[warm saddle]

they might be arthropods but not part of the arachnid class

[warped peak]

Although they are quite close in all honesty. They're the first major Chelicerates, followed by Horseshoes and Arachnids basically

[thorn grove]

A question from my brother:

"I’ve been thinking about evolutionary lineages like the Uropygi (whipscorpions) and why they appear to have been preserved so similar to their ancient form with so little diversity. Modern Uropygi have a patchy global distribution which is a relict of a broader Pangean distribution. They diversified in the Carboniferous, and perhaps they were most successful then- fossils are extremely rare, but ~70% of the fossil record is from the Carboniferous despite their persistence into the Holocene. Now there are only ca. 120 spp. compared with some 52 000 spp. of spiders, another order of tetrapulmonate arachnids. It is one thing to say they have been ecologically displaced by the more successful spiders, or that they have been subject to stabilizing selection versus a series of disruptive diversifying events among spiders, but why?? The Uropygi nevertheless persist in marginal situations, filling ecological roles rather similar to some of the more basal spiders such as tarantulas. So why are some lineages so ecologically marginal, species poor, and morphologically conservative (“living fossils”), whereas others are ecologically important, speciose, and morphologically diverse (like spiders)?
Any thought from my distinguished gentlemen colleagues and scholars of dinosaurs?"

[warped peak]

Simply put, Spiders are extremely flexible by all definitions. They can live anywhere reliably, because they feed mostly on insects, and Insects are everywhere

Amblypygids, which are functionally quite similar to Uropygids, do find success in an array of locations, but they're not abundant anywhere. In most terrains, they compete with wasps, beetles, spiders, scorpions, and small vertebrates, which are all extremely abundant and prominent. Ecological competition is easily the biggest issue to arachnids that aren't spiders or scorpions. Harvestmen or whatever you want to call them fit a very weird niche so they see moderate success, same as ticks. But standard ambush predators at that size like Amblypygids struggle because of what's around them. They're actually quite resourceful and have even been recorded fishing! For shrimp, but still.

Spiders are fast, potent ambush predators that are experts at both venom delivery as an ambush, and Crushing as larger forms, and THEN webs exist. Scorpions are excellent at both Crushing and venom, but rarely at the same time. But they're extremely tolerant of everything but cold, meaning there's almost always a spot they can sneak in

Amblypygids and Uropygids struggle to compete with the sheer efficacy of these guys, because they're dominant predators cosmopolitan, able to do roughly the same tricks as them at similar efficiency, and then some. Really their success relies entirely around funny ambushes in tight areas, or caves.

It's important to note that the hayday of the potential crusher arachnids was before the evolution of complex web arachnids and complex vertebrates as a whole too. They're from a different world, and with basically the same toolset as relatives but worse, there's only so much you can adapt and persevere. It's impressive they're still around honestly. Especially since they're dominantly Nocturnal.

I had to look into a lot of this for Kronocharon, because dude is from the Cretaceous and is indistinguishable from modern whipsters basically. It'll never be more efficient to just stab something really hard, when you can stab really hard AND inject venom

Fire name

[halcyon cobalt]

Why is it built like an ornithopod

[rugged river]

Can I thereotically use the Sharp nails of a Velociraptor as a knife?

[sudden wind]

Try not to use chat GPT as it is very environmentally unfriendly.

[umbral kite]

great just add wrenkles to centain part of the body like the limbs and near the jaw for most of them

[frigid delta]

[hybrid spindle]

Yall seen that duonychus?

[pliant cedar]

which

[outer tusk]

what does "sastrei" means

[tough parcel]

The skeleton was collected on a farm named "Pocho Sastre" near Bajada Moreno in the Telsen Department of Chubut Province, Argentina.

[outer tusk]

thank you again Gualicho but I got it ( I asked this question in another server )

[stable sun]

No it isn't, idk why are you using this

[steady rock]

Chatgpt as a source 😬

How accurate is the new eo model?

Like, the new one, its tlc is out rm

All I found so far

[tough parcel]

They abandoned "Eotrike" and went for Trike

[steady rock]

Is juvie eo accurate also?

[bold fog]

Ohh its because Anselmo Sastre the man who the terrain Carnotaurus material was found

I talked with Fernando Novas about it, because if it was because the place would be sastrensis not sastrei if you want i can send you the video i did about Carnotaurus.

[zealous ravine]

We don’t have a juvi Eotrike but it seems to match Juvi trikes

[steady rock]

So eo got it's identity stolen by trike and is dead in a ditch in the potverse?

[ancient crystal]

I mean, eo was never really there, it was pretty much always just trike

[bitter quest]

Is it me or pot eo get bigger

[zealous ravine]

How does the hatchling look?

[zealous ravine]

Matches the UCMP specimen p well

[ancient crystal]

I like how its eyes look like when you pull a dog's ears back

[balmy oyster]

Why’s it so heavily based on triceratops

[hardy sentinel]

Wait is this the official one?

[steady rock]

Yup

[junior dawn]

yeah

[arctic crane]

Is eotrike's bottom beak not reaching the top one accurate? Looks like it couldn't pick things up right

[fossil ingot]

Literally just Trike
Bro ain't Eo

[zealous ravine]

Yep

[ionic crescent]

Found it

[arctic crane]

Its that common among ceratopsians or unique to eo?

[zealous ravine]

Nice, what species is that lower one? Or is it just a slightly crushed trike?

[ionic crescent]

Is chasmo! A close relative

What we have of baby trike actually is the darker part in the cast

[zealous ravine]

Thought so, nice

[soft spear]

A triceratops would actually be fragile against a tyrannosaurus if it could bite the back of its neck and use its weight to knock the EO down. But in the game the tyrannosaurus can't use its mouth to grab other large dinosaurs and use them as a pivot for its body... this will always make life difficult for large carnivores until it is resolved.

[fossil ingot]

Eo is Dwarfed in size even by Torosaurus.
If Eo Sees Rex bro is kinda cooked lol

[tough parcel]

I would suggest using a juvenile animal over an adult to reconstruct a juvenile skull

[whole umbra]

PoT should have chosen Torosaurus as its big ceratopsian instead of eotrike which is basically trike, at least toro looks different enough.

[soft spear]

I'm saying that the tyrannosaurus' teeth are the largest, with a maximum of 30 cm. They are conical teeth that pierce bones. The tyrannosaurus should be able to grab large dinosaurs even as a way of defending itself from enemy horns and mouths. For example, in Jurassic Park 3 when the rex holds the spinosaurus by the neck. This should be in the game.

The Tyrannosaurus' neck and chest are very muscular, beyond normal, added to its long and penetrating teeth it should use its bite to hold, knock down and manipulate the opponent's body

[cloud dagger]

What

[soft spear]

grab you don't understand that word?

[steady rock]

Who are you getting rude with?

[open compass]

Other carnis could hold necks too

[viscid surge]

The “debate” that will never end 🤔

[eager forge]

Acquired a fossil mosasaur tooth yesterday at a curio shop. Unfortunately it is unknown what species specifically it might be from.

[cloud dagger]

More like why are you telling all that on paleo channel and taking jp as a reference

[mortal fossil]

Maip is goth girlfriend confirmed

[tough parcel]

https://tenor.com/view/lion-king-simba-scar-no-idea-gif-7805966

[dawn cliff]

I just got a tooth today too! But it’s a raptor

[lilac hornet]

It's there a comparison of eo vs trike?

[manic holly]

So is the eotrike’s new neck posture good or bad?

[lilac hornet]

I kinda mean side be side eo here is basically covered up

[frigid delta]

Trike is red
Eo is pink

[lilac hornet]

That isn't what im... yes I can see that

[frigid delta]

what i could found

[fossil ingot]

Eo and alberta

[static widget]

How much did you pay for it?

[dawn cliff]

55$

[static widget]

Dam I mean it is just a tooth

[lilac hornet]

Ah ok these are more what I had in mind

Mostly wanted to see how the heads shape and body differed so these are great

I assume eo is the top in the last one?

[brave nova]

There’s it next to a 7ton trike

[lapis yarrow]

Fossilera follow me on instagram lol

[fossil ingot]

Eo seems more like 5 tons similar to Pachyrino then 6t tbh

[lapis yarrow]

Eo just got a big ahh head

[fossil ingot]

Yeah

[rose gate]

But why is it correct in this question though? (It's not a chatgpt)

[ionic crescent]

Kem Kem?

How many serrations does it have?

Because maybe is not raptor but fish xd

[balmy oyster]

It looks AI

[rose gate]

But then.. it answers accurately to the question. What's wrong?

[balmy oyster]

Just because it answered a question about a game with a set amount of playables does not make it reliable for genuine paleontological questions

[rose gate]

So it's accurate then.. if you're so against AI, why are the labs of gene sequencing used AI machine system to save time for them which would take decades to for a human to work and finish?

[balmy oyster]

Ugh 😵

[elfin pulsar]

Tbf that’s different application

Those labs (and more) use ai for their sequencing for example, this is because its a very set and binary process that ai easily speeds up, that is something ai shines in. For something like answering a question regarding a video game that already has some poor documentation that is easily accessible is where ai is pretty notorious for messing up. It’s also why AI is usually terrible for paleontology questions as online there is a LOT of different ranges and misinfo etc, so it can easily pull from unreliable sources

[rose gate]

That's why we shouldn't immediately reject an AI advantages entirely.

[warped peak]

... did you read the message you replied to

[limber condor]

Their eye shape really really bothers me 😭 it looks like a frog... I slapped the baby trike skull over baby so and traced it and the issue is the crest, it's too concave imo

[steady rock]

https://tenor.com/view/yes-cute-peek-a-boo-gif-14963830

[limber condor]

I like the goat eyes, I just don't like how much the eye ridge (?) protudes. Looks weird 😔

[compact leaf]

part of that is angle as well but it also isn’t triceratops, so some variation can take place in the frill

[frigid delta]

what would Trikes prefer?
in groups or solitary?

[limber condor]

But from the adult eo skull we got, it doesn't look like there's this much distance between the eye/horn and crest :(

[dawn cliff]

this is the exact speciemen I bought. https://www.fossilera.com/fossils/serrated-72-raptor-tooth-real-dinosaur-tooth--162

[pallid crescent]

yeah, the skull it a little too underdeveloped id say, that would be more fit for a fetus rather than a baby thats been more developed, the eye ridge is a little off too, but other than that i think its perfect

[limber condor]

I just wish it didn't have these giant horned frog eyes it's so unsettling to look at... Baby eo used to be very cute (though inaccurate)

[pallid crescent]

personally, i think the isles baby trike is more accurate

[warped peak]

A lot of animals have pupils that aren't round

[pallid crescent]

its not the frog eyes thats the problem, its moreso the head shape

[warped peak]

The angle is also super bad

[limber condor]

Yeah it's the head shape. I like the goat eyes

[old river]

Am I the only one thinking that the new Eo has proportion issues ?
Like the head is too smalla and the leg a tad bit too long

[uneven pine]

This is the last place I expect to see you

[manic holly]

So is the new eo posture correct or incorrect?

[balmy oyster]

I exist everywhere

[uneven pine]

lol
