Do you have any facts about frogs or dinosaurs

Yeah, some frogs can trans themselves at will so don't use their DNA to fill in carnivorous dinosaur genomes for theme parks. You can see the results of this in the popular 1993 film, "Carnosaur."

He needs a name! I made a little bit more progress on the carnosaurs model, I'm currently printing his top half to ensure that my snap-fit ball joints work, especially his little arms. :3

Snarling Dynamosaurus, a descedant of Proceratosaurus with photogenic teeth.

A finished comm for my boyfriend!

A carno with no arms (inspired by the idea that their tiny arms were like. Just under flesh because they were that useless).

Three Amigos: Allosaurus Edition

Impressions of the three different species of the Late Jurassic carnosaurian theropod dinosaur genus Allosaurus, which lived in Laurasia 155-145 million years ago, from top to bottom: A.fragilis and A.jimmadseni, which both hail from the Morrison Formation of western North America, and A.europaeus, which hails exclusively from the Lourinhã Formation of Portugal.

As an 8.5 to 9.7 meter (28-32 foot) long fleet-footed predator that was capable of making rapid vertical movements with its neck and had a very wide gape which enabled it to bite repeatedly into the flesh of its quarry, strong jaw muscles in spite of its weak bite force, and grasping hands that were armed with large talons, Allosaurus was superbly adapted to prey upon the ornithopods, sauropods, and thyreophorans that were abundant in a semiarid environment that had distinct wet and dry seasons and flat floodplains that were home to river-lining forests of conifers, ginkgoes, horsetails and tree-ferns as well as sprawling fern prairies, and it also shared its habitat with other large, powerful theropod predators such as Ceratosaurus, Marshosaurus and Torvosaurus.

Strange Symmetries #14: The Tooth About Baryonyx

Almost all toothed theropod dinosaurs had exactly four teeth on each of their premaxillary bones, the paired bones at the very tip of the upper snout.

The semi-aquatic spinosaurids were an unusual exception to this with six or seven teeth per premaxilla – and one particular member of this lineage seems to have been just a little bit weirder.

Baryonyx walkeri lived during the early Cretaceous, around 130-125 million years ago, in what is now southeast England. About 9m long (~30'), it had distinctive enlarged curving claws on the first fingers of its hands, along with a long narrow snout with a "rosette" at the tip followed by a notch (a shape convergent with the jaws of modern pike conger eels).

And that premaxillary rosette had a strangely asymmetrical arrangement of teeth.

The left side had six teeth, and the right side had seven.

Why? We don't know!

Baryonyx skull material is rare and fragmentary, so it's unclear if this was actually a characteristic feature of the species or if the known asymmetric rosette just represents an unusual individual.

Having an art block, take this stylised Spinosaurus while I try to get motivation to make something detailed

A sprite I did for practice of @lighterium‘s jawbreaker carno OC! :}

(I'm bad at naming stuff if you couldn't tell)

I was watching BillMakingStuff making crystals for a frame diorama in one of his videos and for some reason it made me remember a drawing I did when I was like 12 or something of a dinosaur with crystals coming out of it back.

So like... I made one.

Made with a carnosaur toy, miligreen, cheap paint, and a lot of painters tape. Trying to figure out a way to seal the crystals with a gloss spray and the rest of the build with a matte apart was a real pain in the ass. Next time I think I'll seal it all with a matte spray and coat the crystals with modgepodge or something.

I wanna make another one at some point. Probably some kind of four legged herbivore next time.

(I know they're not diamonds but I needed a pun)

Carnivores Allosaurus doodles

Wanted to add some little details on my own to this bizzare dinosaur, I noticed most vintage Allosaurus depictions had a rather bumpy skin texture, surprised not many people have tried to make a mod addon inspired by that.
