The Thaynes Group, Thaynes Formation in older literature, is a geologic group in eastern Idaho, western Wyoming, Utah and eastern Nevada. It includes the Sinbad Formation, Virgin Formation and Shnabkaib Formation. [1] The Thaynes Group is of marine origin. Its formations are interbedded with layers of the non-marine Moenkopi Group. [1]

It preserves fossils dating back to the Early Triassic epoch ( Olenekian stage). The Lower Limestone Member contains the Paris biota lagerstätte, one of the first diverse assemblages of the Mesozoic era. [2]
