Lambdopsalis bulla Chow and Qi, 1978

Fig. 1F–I .

Referred material: 108 complete and partial molars.

Discussion.—Numerous molars of Lambdopsalis bulla have been identified in the Subeng fauna, making the species one of the best−represented taxa in the assemblage, as it is in the nearby Bayan Ulan and Nomogen faunas (Meng et al. 1998; Ting 1998). This taxon has been extensively studied in earlier works ( Miao 1986, 1988; Kielan−Jaworowska and Qi 1990). Stratigraphic and geographic range.— Lambdopsalis bulla is known from the Gashatan (late Paleocene) Nomogen Formation at Nomogen, Bayan Ulan, Subeng and Nuhetingboerhe in Inner Mongolia, China.
