  Danata Formation (Turkmenistan) | |
The Danata Formation (or Danatinskaya, Danatinsk, Russian: Danata Svita) is an Upper Paleocene to Middle Eocene sedimentary succession located in Turkmenistan. It is mostly famous for its fish-bearing horizons (Ichthyofauna).[1] The formation for example crops out in the Kopet Dag mountain range in the border region of Turkmenistan and Iran.[1]
Fossil content
The Danata Formation is famous for its ichthyofauna. The fish are found in a 9 metres (30 ft) thick clay horizon in the middle of the succession, that has been dated as Upper Paleocene.[1] 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.[2]
A similar fauna occurs in the Moler Formation in Denmark.[1]
