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]
