English: Map of the range of the indricothere genus Forstercooperia, which lived in East Asia during the Eocene. All species of Forstercooperia can be found in the Irdin Manha Formation, from multiple specimens. The Lunan Formation is where the holotype of F. shiwopuensis is from, now considered the only non-typic specimen of F. totadentata. Forstercooperia minuta remains were identified from this formation in 1997. The Sargamys Formation is where the only specimen of "F. crudus", potentially a synonym of F. minuta, is from. Reports of indricothere remains from both the Bose Basin and the Lushi Basin seperately identified these as Forstercooperia sp.
