This is the definitive study of middle Miocene life in Wyoming. The important Split Rock fauna is comprehensively analyzed here for the first time. Studies of fossils collected since 1870 have resulted in major contributions to knowledge of several mammal groups, particularly the mylagaulid and geomyoid rodents. The fossil's ecological context is portrayed through a detailed revision of regional lithostratigraphy.
