Perspective

A diverse fauna has been unearthed from the Aitym Formation including oysters, ammonites and many marine vertebrates, including an abundant assemblage of chondrichthyans (cartilaginous fish), a rarer assemblage of osteichthyans (bony fish), 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 (including birds), and mammals have been found in the formation.[1]
