Description
The family Apatemyidae has a long geochronological range in North America, beginning in the Torrejonian land-mammal age, but is represented by a relatively small number of fossils found at a few localities. Two fossils of Orellan age, found in northeastern Colorado and described here, demonstrate that the geochronological range of the Apatemyidae extends into the Middle Oligocene. Isolated teeth of Sinclairella dakotensis Jepsen, part of a sample of a Chadronian local fauna collected by field parties from the Webb School of California, are also described.
