About This Book
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.
