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