Field Museum paleontologist leads study on two new dinosaurs from China
Date:4/21/2009

ed dinosaurs tend to dominate red rocks deposited under dry conditions across almost all Cretaceous localities in the Gobi Desert, whereas tyrannosaurs, ornithomimosaurs, and duck-billed dinosaurs tend to occur in rocks deposited in wetter environments. The fauna collected by the Chinese-American team in Gansu shows evidence of such environmental separations between different kinds.

The fauna collected by the Chinese-American team in Gansu shows evidence of such environmental separations between different kinds of dinosaurs, and represents one of the earliest instances of both the environmental sorting of animals and the very stable, but depauperate, lineage composition of Cretaceous Central Asian dinosaur faunas that reined for the next 50 million years. Professor Gao Ke-Qin of Peking University, who also took part in this research, notes, "The abundance of new dinosaurs from Chinese localities like the Yujingzi Basin, allows us to study the long history of dinosaur evolution in light of both geographic and environmental parameters in a way that is impossible elsewhere in the world."
