Khatyspyt Formation

The Khatyspyt Formation is a Neoproterozoic formation exposed in the Olenëk Uplift of north central Siberia,^[1] which contains the only known instance of the Ediacara biota preserved in a limestone bed.^[2] The Khatyspyt formation forms one of the major parts of the Khorbusuonka Group; underlying the Khatyspyt are dolomites of the Mastakh formation and their overlying red beds; the Turkut formation overlies the Khatyspyt. The Khatyspyt and part of the overlying Turkut comprise a major shallowing upward marine carbonate sequence. ^[3] Khatyspytia is named after this formation.^[4]
