Khilok Formation
The Khilok Formation is an Early Cretaceous geologic formation in Buryatia, Russia. While the lower portion of the formation consists of sandstones and conglomerates, the upper portion of the formation largely consists of trachybasalt, these deposits have been dated to the Aptian.[1] A thin 20 cm bed is known from the formation containing the remains of numerous indetermiate vertebrates, including dinosaur and pterosaurs and an indeterminate species of Kirgizemys.[2]
