Field notes

About Nemegtosaurus

What it was like

Nemegtosaurus was a titanosaur, a long-necked plant eater about 13 meters (43 feet) long. It is known mostly from a single skull, which is long and low, with thin, pencil-like teeth at the front of the jaws.

Its world

It lived in the Late Cretaceous, in what is now Mongolia. The Nemegt Formation was a land of rivers shared with the tyrannosaur Tarbosaurus, the giant clawed Therizinosaurus and the duckbill Saurolophus. Some scientists think Nemegtosaurus may be the same animal as Opisthocoelicaudia, which is known from a headless skeleton in the same rocks.

How it was found

Nowinski named Nemegtosaurus in 1971. It was found by a joint European and Mongolian expedition.
