Two New Localities of Mesozoic Mammals in Russia (Krasnoyarsk Territory, Lower Cretaceous)

摘要

Two new localities of Mesozoic mammals have been discovered: Bol'shoi Ilek and the Berezovaya River (Russia, Krasnoyarsk Territory, Lower Cretaceous, Ilek Formation). Bol'shoi Ilek locality has yielded an edentulous fragment of the maxillary of Docodonta indet. A fragment of dentary without teeth attributed to Mammalia indet. (presumably eutriconodontan or symmetrodontan) has been found at the Berezovaya River locality. These new localities fill the geographical gap between previously known mammalian sites of the Ilek Formation in the basins of the Kiya and Bol'shoi Kemchug rivers.
