Abstract

Only one rodent specimen has been previously described from the late Hemphillian ZX Bar local fauna from Sioux County, Nebraska-the holotype of the heteromyid Perognathus coquorum Wood. A re-examination ofthis specimen has led to its allocation to the dipodomyine heteromyid genus Prodipodomys Hibbard. An additional specimen of a fossil rodent has been recognized from the ZX Bar fauna that is referable to a new species of the primitive geomyid Pliogeomys, P. russelli.
