Marine geologial formation in weatern Turkmenistan / From Wikipedia, the free encyclopedia
The Danata Formation (or Danatinskaya, Danatinsk, Russian: Danata Svita) is an earliest Eocene 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]

Previously, it was thought that the earliest horizons of this formation dated to the latest Paleocene (Thanetian). However, more recent studies have found the formation's sapropel to originate from a global anoxic event caused by the Paleocene-Eocene Thermal Maximum, indicating that it formed just after the Paleocene-Eocene boundary, during the earliest Ypresian.[2]
