A Miocene Mammalian Fauna From Sucker Creek, Southeastern Oregon

Deposits occurring along Sucker Creek, a tributary of the Snake River, in southeastern Oregon, have yielded a small mammalian fauna which is correlated with the Virgin Valley fauna of Nevada and the Mascall fauna of Oregon, both of Middle Miocene age. The Sucker Creek fauna, though much less complete, closely resembles that from Skull Spring, a locality forty miles to the west. The beds are correlated with the Fayette formation of southwestern Idaho and have yielded also a Payette flora. The fauna indicates a semi-humid, forest environment
