Genus Prionessus Matthew and Granger, 1925 Prionessus sp.

Referred material: IMM− 2004−SB−019, fragmentary right M1.

Discussion.— Prionessus lucifer is known from all classic Gashatan faunas ( Ting 1998), and one fragmentary molar from Subeng is assignable to this taxon. Meng et al. (1998) tentatively distinguished a possible second morphotype of Prionessus , Prionessus cf. P. lucifer , at Bayan Ulan, based on the possession of a double−rooted p4. Given this uncertainty, IMM− 2004−SB−019 is here referred to Prionessus sp.
