The Ulan Shireh Formation is a geologic formation in Inner Mongolia, China. The Ulan Shireh Formation preserves fossils dating back to the Middle Eocene, including mammals of the Irdinmanhan land mammal age.[1] The Ulan Shireh Formation is correlated with the Irdin Manha Formation, also in Inner Mongolia, and is believed to have been deposited in the same timeframe.[2]

B.? sp.
Desmatotitan[3][4] D. tukhumensis A brontothere
Epimanteoceras[3][4] E. formosus A brontothere. Ye (1983) reported both E. formosus and Dolichorhinoides angustidens, species now regarded as synonyms.[3]
Forstercooperia[3][4] F. ulanshirehensis A paracerathere. Reported by Ye (1983) as F. cf. grandis.[3] Described as F. ulanshirehensis in 2018.[4]
"Lushiamynodon"[3][4] L. sharamurensnsis An amynodont. The genus Lushiamynodon is probably a synonym of Sharamynodon[5][6] but L. sharamurensis is based on fragmentary remains.[6]
