Nemegtosaurus by Moondawg

It was named after the Nemegt Basin in the Gobi Desert, where the remains were found. It may have had a long, sloping head and, like most sauropods, had peg-shaped teeth.

The type species, Nemegtosaurus mongoliensis, was first described by Nowinski in 1971. A second species, N. pachi, was described by Dong in 1977, but is a nomen dubium.
