dc.description.abstractCave Basin is a Mid-Miocene vertebrate fossil site located on the South Fork of the Crooked River, near Paulina in Central Oregon. In this basin, the Mascall Formation is composed of tuffs, paleosols, diatomites, fluvial and lacustrine sediments, producing floral, macrofaunal, and microfaunal vertebrate fossils. I describe seven genera of squirrels from the Cave Basin fauna, including a new latest Hemingfordian boundary species of Miospermophilus and the first record of Miopetaurista in the Miocene of North America. The sediments and diverse community of terrestrial, arboreal, and semifossorial squirrels found at Cave Basin indicate an environment supporting woodland, marginal forest, and non-forest environments around a body/bodies of water with nonpermanent boundaries. The Cave Basin assemblage provides a window into the diversity of local environments and mammalian communities present during the MidMiocene Climatic Optimum. Additionally, the Cave Basin sciurid assemblage is one of the most diverse in Oregon and highlights the range of micromammal niches available in mixed environments.en_US
