Late Eocene Multituberculates and Other Mammals from Wyoming.

Isolated teeth of multituberculates have been found in association with late Eocene fossil mammals. Previous studies reported that multituberculates were not found in deposits younger than early Eocene age (Graybull provincial substage or equivalents). This newly found occurrence indicates that these animals are more likely to be late Eocene in age than reworked early Eocene materials.
