In Depth Gorgosaurus had the same basic body plan of all tyrannosaurids with a large head on an s-shaped neck, small arms and bipedal stance. With around sixty teeth in its mouth (there is some variance between specimens) Gorgosaurus shared a common trait with other tyrannosaurids of its size, as the larger the tyrannosaurids go … Read more
In Depth So far only known from a partial skeleton, Chialingosaurus was still one of the first and hence most important stegosaur discoveries to take place in Asia.
