Abstract

According to the degree of development of the main cusps and the presence of a small lingual part, the upper molar of a docodontan from the Bol’shoi Kemchug 4 locality (Ilek Formation, Lower Cretaceous) in the Krasnoyarsk Territory corresponds to M1 of Agilodocodon scansorius Meng et al., 2015 from the Middle Jurassic of China. The described tooth may belong to Sibirotherium rossicum Maschenko et al., 2003 known from more complete remains (without M1) from the Ilek Formation of the Shestakovo 1 locality (Kemerovo Region), which could have four upper molars similar in structure to those of Agilodocodon.
