Abstract

. In August 1970, an investigation was made of the remains of a mammoth, Mammuthus cf. M. columbi, exposed west of Oakland, in Pottawattamie County, Iowa. A segment of proboscidian tusk, a lower third molar, and additional skeletal fragments were collected from the Wisconsin loess. Associated with the mammoth was a small-mammal fauna consisting of Phenacomys intermedius (heather vole), Microtus pennsylvanicus (meadow vole), and Vulpes vulpes (red fox), extant species with an area of sympatry immediately north of the Minnesota-Canadian border. This fauna, here designated the Oakland local fauna, supports cooler summers in western Iowa during Wisconsin loess deposition.
