InGen Database Description
The Nemegt Formation (also known as Nemegtskaya Svita) is situated in the Gobi desert in Mongolia. It overlies the Barun Goyot Formation. Although not precisely dated, the formation dates at least as far back as the Maastrichtian age of the Late Cretaceous, 70 million years ago.
The shales and sandstones of the formation are the remains of streams, rivers, lakes and floodplains. Remains of petrified wood and Araucariaceae conifers suggest the area supported great conifer forests and other vegetation. The sediments suggest a rich environment capable of sustaining abundant life. It was likely to have been a wet environment.
Remains of crocodiles, turtles and fish have been discovered here. Egg remains for at least two dinosaur species have been recovered. In 2007 the fossilized footprints of a large sauropod were discovered.
