Dinosaur fossils found in July, 1995, near Dariv, western Mongolia, re present the first dinosaurs of Jurassic age described fron Mongolia. T he 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 t hat accumulated in. a seasonally wet, collisional foreland basin just prior to an episode of uplift of the ancestral Altai Range in latest J urassic time.
