About Elmisaurus
What it was like
Elmisaurus was a small feathered dinosaur from the caenagnathids, toothless relatives of Oviraptor. It is known from hands and feet, and its foot bones were fused together, a little like those of birds.
Its world
It lived about 72 to 66 million years ago, at the end of the Late Cretaceous, in what is now Mongolia. Its bones come from the Nemegt Formation, where it shared the land with the giant clawed Therizinosaurus, the hump-backed Deinocheirus, the ostrich-like Gallimimus and the tyrannosaur Tarbosaurus.
How it was found
Osmolska named Elmisaurus in 1981. Four finds are known.
