Erlikosaurus

Erlikosaurus andrewsi

Erlikosaurus (meaning "Erlik's lizard") is a genus of therizinosaurid that lived in Asia during the Late Cretaceous period. The fossils, a skull and some post-cranial fragments, were found in the Bayan Shireh Formation of Mongolia in 1972, dating to around 96 and 89 million years ago. These remains were later described by Altangerel Perle and Rinchen Barsbold in 1980, naming the new genus and species Erlikosaurus andrewsi. It represents the second therizinosaur taxon from this formation (after Segnosaurus), with the most complete skull among members of this peculiar family of dinosaurs. In contrast to most therizinosaurids, Erlikosaurus was a small member reaching nearly 3.4 m (11 ft) in length and 150 to 250 kg (330 to 550 lb) in mass
