Out of all the theropods that I scanned at the @nmnh, Ceratosaurus was the one theropod that I looked forward to the most. I cannot wait to do an FEA study on the horned-lizard! (2/2)

First it’s a proceratosaurid and probably the most unique in contrast to Guanlong and Proceratosaurus. Then again proceratosaurids are a rather unique group of tyrannosaurs.
Guanlong and Yutyrannus by @SerpenIllus.

Here’s #Tarbosaurus (“alarming lizard”), a Mongolian tyrannosaur for #Theropodacember. Art by Dmitry Bogdanov.

Here’s a more derived tyrannosaur for #Theropodacember, #Dilong (“Emperor Dragon”). A small, feathered tyrannosaur with cranial elements that will be present in later tyrannosaurs (fused nasals). From Dilong to T. rex, big things have small beginnings. Art by Alex Lovegrove.

Since I’ve already talked about Gorgosaurus, here’s another Canadian tyrannosaurid for #Theropodacember, #Daspletosaurus (“frightful lizard”). Art by @SerpenIllus.

Our next tyrannosaur for #Theropodacember is #Guanlong (“crown dragon”), my favorite early tyrannosaur. Fantastic art by @ChrisDPiazza showing a Guanlong pack being attacked by Sinraptor (center), illustrating the small beginnings of tyrannosaurs.

Austroraptor and other unenlagines of the Southern Hemisphere serve as a contrast to dromaeosaurids of the Northern Hemisphere, in terms of cranial evolution and feeding ecology/behavior. Art by @FredtheDinoman.

Introducing #Compsognathus (“elegant jaw”) for #Theropodacember. It’s also my mother’s second favorite dinosaur, given it’s small size. Compsognathus does serve as a good comparison for smaller theropod dinosaurs, especially coelurosaurs. Art by @SerpenIllus

It’s such a bizarre theropod that I want to see how the skull would have functioned with biting and dismembering prey. Plus it belongs to Noasauridae, a group of theropods with unique anatomical features. Art by Tupandactyl.

The study showed that Dilophosaurus’ skull was more robust, had more expanded crests and probably capable of delivering a powerful bite, much to the appeal of biomechanics enthusiasts like myself. Fantastic artwork by @BrianEngh_Art to illustrate the ferocity of Dilophosaurus.
