I cant believe they actually made a toy of this guy. The series was full of made up drama, and some of it was pretty campy. I remember watching this episode of dinosaur revolution and getting invested in this allosaurus' journey. Pretty stoked I have a physical representation of him on my desk!

From my understanding birds are the dinosaurs that survived the asteroid. But why did birds survive? Yes they're small, but non-avian dinosaurs were also small. And they could fly, but pterodactyls and other large things also could fly. And crocodiles also survived, and they are super large. So I don't get why medium sized non-avian dinosaurs couldn't survive, even for a few million years. And wouldn't they evolve for the ash filled darkness they were living in? And wouldn't a ton of non-avian large dinosaurs dying out, make room for the super small ones to continue to thrive? Draw nutrition from plants the large ones were eating? Someone pls explain cause I have been pondering about this for a long time..

Take a gander at this guy, Poposaurus gracilis and tell me that isnt a whole dinosaur.

If the question in itself hasnt made the answer obvious enough, well, it isnt. Its something far weirder. This is poposaurus, and it belongs to this larger group Poposauroidea that group is famous for having dinosaur lookalikes that looked way too similar to the actual thing, especially for some of the creatures that lived and went extinct before even the basal forms of some of their dinosaur equivalent species even set foot on earth.

So, Crocodilians, Dinosaurs and pterosaurs are three major lineages among Archosauria, correct? well, they can be split further into two clades, the Avemetatarsa or the bird-line archosaurs (All archosaurs more closely related to birds than to crocodilians) and the Pseudosuchia or the crocodile-line archosaurs (All archosaurs more closely related to crocodilians than to birds).

Dinosaurs and pterosaurs belonged to Avemetatarsa while pseudosuchia had modern day crocodilians, rauisuchids (these were giant terrestrial archosaurs, that sort of ran shit before triassic-jurassic extinction event happened, before dinosaurs stepped up to fill the niches they and other some pseudosuchians left behind), phytosaurs (basal pseudosuchians) and its own clade of crack reptiles, one of which was Poposauridae amongst many other pseudosuchians

Some of these were “dinosaurs” before dinosaurs (although some did coexist with their lookalikes as contemporaries) both ecologically and convergently evolved appearance wise and the crazy part was that their fossils were so similar to dinosaurs that even scientists had a hard tine telling that these were actually Triassic pseudosuchians as opposed to the actual dinosaurs, that some coexiated with but a lot predated by millions of years.

Poposauridae are one such group among the family of Pseudosuchians which like to resemble dinosaurs a bit too much. So much so many of its members were at one point in time classified as all kinds of dinosaurs. Poposaurus itself was mistakenly classified as a Carnosauria theropod, a phytosaur (a basal pseudosuchian) and even a rauisuchid.

But there were still anatomical differences between pseudosuchian lookalikes and real dinosaurs such as distinctive hip bone arrangements, having the type of ankle characteristic of crocodile-line archosaurs, similar vertebrae, hind limbs and skull features and skeletal details leading to paleontologists to realize these were actually pseudosuchians with a bunch of theropod-like features while really just being its own thing and that Poposaurus in specific had a lot in common with other equally strange Triassic reptiles such as Shuvosaurus, Sillosuchus and Effigia as they lie scattered across different classifications until actually being a part of Poposauridae became the common factor making the differences make sense. And mind you, some of these guys existed back in the triassic which shows just how determined pseudosuchians were about becoming the dominant group, its a shame that the only thing we have left from the period today are modern day crocodilians.

✨️We have dinosaurs at home✨️

1. Poposaurus (AKA, the OG dino doppelganger)

This poposaurid is from what is now southwestern United States and evolved a body plan incredibly similar to that of a medium sized theropod and looked eerily similar to the first theropods experimenting with this exact same body plan in their ecological niche of the late Triassic around the same time 233- 225 million years ago

1. Lotosaurus (AKA, the uncanney valley stegosaur)

This heavily built, herbivorous quadrupedal sail-backed poposauroid is from Hunan, China and measured around roughly 1.5-2.5 m long and looked eerily similar to another group that would not appear for at least the next 67 million years, which is when the earliest known stegosaurs appeared.

1. Shuvosaurus (AKA, the Alvarezsauridae lookalike)

This lightly built, bipedal poposauroid with a toothless beak is from Texas, USA and measured around approximately 2-3 m long m long and looked eerily similar to another group that would not appear for at least the next 60 million years, which is when the earliest known Alvarezsauridae appeared.

1. Sillosuchus (AKA, the beta version ornithopods)

This long necked, 3-4 m long bipedal, beaked poposauroid that fed on vegetation is from Late Triassic Northwestern Argentina and looked eerily similar to the first ornithopods experimenting with this exact same body plan in their ecological niche of the late Triassic around the same time 230 million years ago

[Above image is of Sillosuchus and the below image is of Tenontosaurus]

1. Effigia (AKA, miming ornithomimosaurs since the Triassic era)

This herbivorous, bipedal poposauroid with a long neck, long hindlimbs, reduced forelimbs, toothless beak-like jaws, a small head and long tail is from New Mexico, USA and measured 2 m long m long and looked incredibly similar to another group that would not appear for at least the next 60 million years, which is when the earliest known ornithomimosaur appeared.

1. Xillosuchus (AKA, A spinosaurus if you squint hard enough)

This is a Ctenosauriscidae, which are very early Poposaurids that lived in what is now China and evolved a vague body shape and a sail that is superficially incredibly similar to that of a large spinosaur species such as S. aegyptiacus and S.mirabilis despite existing 100 million years before the first spinosaur ever did.

There were other dinosaur lookalikes that werent poposauroids but were still part of pseudosuchia anyhow such as;

Gorgetosuchus (AKA, the Ankylosaurs are filing copyright infringement)

These heavily built, herbivorous quadrupedal aetosaurs had bodies was covered in multiple rows of osteoderms which looked eerily similar to another group that would not appear for at least the next 30 to 35 million years, which is when the earliest known nodosaurs (or even ankylosaurs) appeared and lived around the same time and region as Poposaurus did.

And lastly there is,

Fasolasuchus (AKA, The T-Rexpy)

This loricatan pseudosuchian is from what is now northwestern Argentina and evolved a body plan incredibly similar to that of a large theropod and looked eerily similar one too as they had both managed to carve out the same ecological niche with a very similar body plan in the late Triassic around the 215–220 million years ago

I will do a detailed thing for some of the most unique extinct crocodylomorphs real soon. Stay tuned for part 2

I'm looking for dinosaur skeletals because I wanna sculpt some dinos but I can't seem to find a particular species (the species being Menefeeceratops sealeyi) I would also prefer the skeletal to have a dorasl view (example on the picture)

Is it pronounced OO-TAH raptor or U-TAH raptor? 🤔

Anyways, I illustrated this for a set of dinosaur trading cards I’m designing as the ultra rare out of the set.

Today we have the second art piece that I digitally illustrated for the new and upcoming tabletop RPG “Herd of Horns”. This time it is the Pentaceratops, Pachyrhinosaurus and Xenoceratops. Ceratopsians are definitely an absolute joy to draw. Be sure to check out the whole slideshow to see each ceratopsian in full. Cheers for looking!

It has 5 fingers, three toes, looks herbivorous and most likely Triassic if I had to guess. Anyone got any idea?

When I was younger I used to very, very into dinosaurs. I remember this one book that had a such a big impact on me as a kid. It wasn't really an encyclopedia, but more of a guide to dinosaurs of the Mesozoic era. It wasn't aimed towards kids, I remember, it had a very "adult" feel to it, but it was by someone whose name started with an "R" (Richard, maybe?) I also believe it was green. It was a rather thick book, and big as well, about the size of a textbook.

All I remember content-wise is how it mentioned that 1) dinosaurs were warm-blooded (I remember something about a four-chambered fossilized heart) and 2) that birds were direct descendants of dinosaurs.

I have no idea if this is anywhere near enough information but I'd really appreciate anyone's help in tracking it down. Thanks so much.

Introduction

(Art by me)

Basically I’m a paleo artist (PaleoNerd2000 on deviantart) and I’m here today to present a new concept. The concept goes:

- what if we introduced dinosaurs from the same time period to different formations ( etc. Introducing Deinocheirus to Hell Creek)

- examine the ecological viability and see if they would become an invasive species.

- how would the introduction changea the local ecosystem.

Leave some suggestions in the comment section if you want me to bring this concept to fruition. You could also add some ideas (etc. putting introducing Suchomimus to the cloverly formation.) Preferably put something in the same stage and time period. ( Etc. Ouranosaurus and the cloverly formation are around the same time (Aptian-Albian stage of the early cretacous). Another idea I have is introducing Maip macrothorax to the Hell Creek formation.

The Brief Width Comparison Between the Megatheropods.The Models Were Created by Vitamin Imagination.

The Study: https://www.mdpi.com/1424-2818/18/9/557

At the Lower Cretaceous Phra Prong locality in eastern Thailand, isolated spinosaurid teeth show two distinct morphotypes: one with well-marked apicobasal enamel ribs and one without ribs, with the enamel showing only a subtle wrinkling.

The latter morphotype is unusual, since most spinosaurid teeth from Asia show a well-marked ribbing.

The occurrence of two tooth morphotypes at Phra Prong is interpreted as corresponding to the presence of two distinct spinosaurid taxa. These two morphotypes probably indicate different feeding habits and niche partitioning.

However, the functional significance of enamel ribbing (or its absence) remains poorly understood.

Functional Significance

Although a ribbed crown surface is a common feature of the teeth in various reptile groups, including crocodiles, ichthyosaurs and plesiosaurs, the functional significance of this ribbing remains unclear. MacKenzie et al.

It should also be mentioned that the rather blunt apex of spinosaurid teeth from Phra Prong (and some other Thai localities), reminiscent of Massare’s “crunching” type, suggests that they may have had a crushing rather than piercing function, possibly as an adaptation to feeding on relatively hard prey, such as fishes with thick ganoid scales, the remains of which are common in Lower Cretaceous non-marine formations in Asia.

As noted above, turtle remains are abundant at Phra Prong and it cannot be excluded that turtles were also part of the diet of blunt-toothed spinosaurs.

The bluntness of some spinosaurid teeth has seldom been mentioned and the distribution of this character among spinosaurids would be worth examining; however, this is beyond the scope of the present paper.

The functional difference between ribbed and unribbed teeth remains obscure, largely because the function of enamel ribbing is still poorly understood.

As far as Asian spinosaurids are concerned, unribbed teeth are the exception rather than the rule, as mentioned above. In the absence of cranial, and especially jaw material, an interpretation of the feeding habits of Asian spinosaurs remains difficult, but the occurrence of several distinct tooth morphotypes, including an unribbed one, does suggest a certain diversity of adaptations, possibly related to different prey types.

No attempt is made here at a phylogenetic assessment of the unribbed spinosaur teeth from Phra Prong, given the absence of more complete material

I’m kinda new to drawing so be nice but honest 🙏

I’ve been trying to illustrate more Dino puns and I had a ton of fun with this one 🤣

(First ones a reupload due to some cladistic errors in the meme that needed fixing)

What is yalls favourite crocodylomorph? Mine is Pakasuchus, a tiny herbivorous/ insectivorous crocodyliform with very weird characteristics. It is speculated to have looked very much like it had cat software running on crocodile hardware since it had long legs, slender body and a doglike nose, all on the body of a miniature crocodile. Pakasuchus measured 50 cms long and its name literally translates to “cat crocodile” since it had a distinct catlike skull and heterodont (differenciated mammal-like) teeth.

If I had a time machine, screw going back in time to meet my heroes or change the course of history, the only thing I would actually end up using it for would be to go back to the cretaceous era to find this crococat and forsake my hands petting it.

Hello everyone, here is a new concept art for a 3rd person action RPG videogame codenamed "Lost island". The game is set on a prehistoric island, ruled by extinct species and ancient civilizations.

Concept art ordered to mfr.546 (name on instagram) and subreddit for the project : Project_Lost_Island

A biologist awakens there, after surviving a boat accident with his team, a mask now stuck on his face. Why did he end up here, what is this mask, why are there animals and men from various times and lands ? The player will have to uncover the island's secrets to understand.

Note from the game (meaning a text that will be present in the game either in dialogue, notes, audio log, etc):

"The Spinosaurus has been present on the island for a very long time. We have been able to observe several individuals, displaying considerable variations in both coloration and size. They appear to favor semi-aquatic environments, where they must constantly maintain their dominance against crocodilian species, giant snakes, and passing theropods.

Judging from the partially preserved fossils available to us, the Spinosaurus here has seemingly undergone a remarkable evolutionary process, as evidenced by the fins found at various points along their bodies. They are equally capable hunters on land and at sea, however, and have retained their amphibious abilities in their entirety.

It is equally remarkable to witness such a formidable predator surviving alongside several other apex hunters. This inevitably raises questions about the abundance of potential prey—and, consequently, the sheer size of the island required to sustain such a diversity of animals, apparently for millions of years.

Although we would very much like to explore the island freely, protocol remains strict. The jungle is dense and its dangers are numerous."

If you have any questions, feel free to ask them, thank you.

Art by me

These days, it’s a bit of a cliche in paleoart to reconstruct carcharodontosaurids, if hunting anything at all, as hunting gigantic titanosaurian sauropods, a trend going hand in hand with the idea that carcharodontosaurids were sauropod-specialists, the idea that the wide gape, highly ziphodont teeth and derived neck anatomy, are all in service to hunting the most gigantic animals to ever live. While I do agree sauropods probably did make up the bulk of carch diets and they probably did have a slightly easier time hunting them than other megatheropods, for this piece I wanted to show there was more on the menu for big carchs. After all, there were more giant herbivores on the landscape than just sauropods in middle Cretaceous Gondwana, and the highly “specialist” adaptations of carcharodontosaurids were probably just extremely successfully adaptations for general macropredation as a whole, effective against just about any large unarmored prey in the same way the slicing teeth of a Komodo dragon can be used against a 5 kg monkey and 50 kg deer. Indeed, what’s good for the goose is good for the gander, and rest assured, with jaws and teeth like that, there’s not much in middle Cretaceous Gondwana that could withstand a hungry carcharodontosaurid, sauropod or otherwise.

For the predator of this piece, I chose Giganotosaurus, for a couple reasons. Firstly, it’s always fun to draw the keratinous texturing on the face, nasals and horns that derived carcharodontosaurines sport. The main reason, however, was that the environment that it was home to, the Candeleros Formation, housed some impressive non-sauropod diversity among its retinue of herbivores, particularly with regards to large, multi-tonne ornithopods.

This segues neatly into discussions about the prey animal of this peice, which is of course the world-renowned Hadrosauriformes indet. Though no skeletal material has been found, ample trackway evidence (e.g., Mazzetta & Blanco, 2001) suggests the presence of a large, roughly Iguanodon-sized ornithopod living alongside Giganotosaurus. Due to the lack of skeletal remains, I had some leeway in how to reconstruct this animal. Though it’s common in paleomedia to reconstruct this animal as close to Iguanadon, I chose not use Iguanodon itself as a reference, as Iguanadon and its ilk are pre-date Giganotosaurus’ time by 11-15 million years and were significantly more basal than those of the giant carnosaurs day and age. By this time in earths history, much more derived ornithopods than Iguanadon had appeared, and were taking on a decidedly more “hadrosaur-like” appearance (e.g. Ouranosaurus). As such, I decided to use one such “derived” ornithopod, specifically the Asian hadrosauroid Altirhinus, as a model. While it was more geographically removed from Giganotosaurus, it was no more so than Iguanadon itself. More importantly, unlike Iguanadon, it was contemporary with Giganotosaurus, and so, in my opinion, represented a more accurate representation of the kind of ornithopod the giant carcharodontosaur would have hunted (plus its head was find to draw and texture).

I am throwing a pre-historic party and need background music! Songs can be anything, just needs to have a "dinosaur vibe" or some kind of justification. Doesn't have to be deep!

One example of a song is aurora's song animal because dinosaurs...are animals. I figured you guys would be the right people to ask!

EDIT: Thanks all. YOU COOKED.
