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.
