Aitym Formation
The Aitym Formation is a geological formation in Uzbekistan which possibly dates to the Santonian stage of the Late Cretaceous period.
The formation has not been precisely dated. However, certain fossils suggest the formation was deposited during the Santonian stage of the Late Cretaceous period.A diverse fauna has been unearthed from the Aitym Formation including oysters, ammonites and many marine vertebrates, including an abundant assemblage of chondrichthyans, a rarer assemblage of osteichthyans, and rather infrequent finds of plesiosaurs, and sea turtles. Terrestrial vertebrate remains are extremely rare in the formation. A few bones of salamanders, lizards, crocodiles, possibly terrestrial turtle remains, dinosaurs, and mammals have been found in the formation.Mammals
