Ulan Malgait Formation
Introduction The '''Ulan Malgait Formation''' is a Late Jurassic geologic formation in Mongolia. Dinosaur remains are among the fossils that have been recovered from the formation, although  none have yet been referred to a specific genus.It is best known for the '''Shar Teeg''' locality which has lent its name to Shartegosuchidae, a family of mesoeucrocodylians (relatives of crocodilians), many of which have been found there; ''Shartegosuchus'' (the family's type genus) means "Shar Teeg crocodile". It is divided up into 2 subunits, the lower '''Shar Teg Beds''' and the upper '''Ulan Malgait Beds'''.The tritylodontids ''Shartegodon, Nuurtherium'' and ''Bienotheroides'' are known from the formation., As is docodontan ''Tegotherium''. The turtles ''Annemys levensis'' and ''Annemys latiens'' and crocodylians ''Sunosuchus shartegensis'' and ''Adzhosuchus fuscus'' were also recovered from the formation. Numerous species of insects are also known from the formation. which was deposited in a lacustrine environment.
Age Dollman et al. (2018) argue that the age of the Ulan Malgait Formation is likely to be Oxfordian based on the shared presence of ''Shartegosuchus'' and ''Nominosuchus'' with the radiometrically-dated Shishigou Formation of China.
