Abstract

Dinosaur fossils found in July, 1995, near Dariv, western Mongolia, represent the first dinosaurs of Jurassic age described from Mongolia. The fossils derive from at least three types of dinosaurs, and include the right foot of a sauropod tentatively identified as Mamenchisaurus sp. The dinosaur fossils occur in Upper Jurassic floodplain deposits that accumulated in a seasonally wet, collisional foreland basin just prior to an episode of uplift of the ancestral Altai Range in latest Jurassic time.
