Kelmayisaurus, Chinese Carcharodontosaur

Galvasean

First time I've heard of Chinese carcharodontosaur. Turns out there's actually two of them!

Unraveling the identity of Kelmayisaurus required two steps. First, Brusatte and co-authors had to determine whether the dinosaur could be distinguished as a unique species. Contrary to the idea that the remains were too scrappy to make such a determination, Kelmayisaurus had a distinctive groove on the front portion of the outside of the lower jaw. Kelmayisaurus is a valid dinosaur name, after all.

With the first question resolved, the paleontologists set about determining what sort of dinosaur Kelmayisaurus was. The best-supported hypothesis was that Kelmayisaurus was a carcharodontosaurid, related to Giganotosaurus, Acrocanthosaurus and others. Aspects of the Kelmayisaurus toothrow, such as the depth of some of the bone around the teeth, and the absence of features often seen in other groups of predatory dinosaurs placed the dinosaur among the “shark-toothed” predators. Though not as large as some of the largest dinosaurs in this group, Kelmayisaurus was still pretty big—about the size of its distant cousin Allosaurus.

Finally! The identity of another mysterious dinosaur, revealed at last! I'm glad to know that it is valid after all.

I'm surprised I haven't read an article called "T-rex's mysterious Asian cousins" or something to that effect.

Unfortunately I remember a tv documentary that mentioned T'rex's Asian 'cousins' I have avoided mentioning it before, partly because I agree with you on this and partly because I can't remember the tv program it was on.:(

Hopefully it was about Tarbosaurus, Alioramus, etc.
