The Danata Formation is famous for its ichthyofauna. The fish are found in a thick clay horizon in the middle of the succession, that has been dated as Upper Paleocene. This includes fossils of the family Turkmenidae. Luvarus necopinatus was first described in this formation. Other fossils of fish include the genera Eospinus, Danatinia, Exellia, Turkmene and Avitoluvarus. The snake species Archaeophis turkmenicus has also been described.Head et al., 2005
