is an extinct genus of North American carnivorous mammals
that lived during the Eocene
to late Oligocene
approximately 40 to 27 million years ago. They were similar in morphology to both bears and dogs (see: Bear-Dog
). The coyote-sized daphoenine beardogs (Daphoenus vetus) along with the nimravid cats, were the largest carnivorans in North America during the mid- to late Cenozoic
that characterized the last 40 million years.
Daphoenus fossils found in late Oligocene rocks in the Great Plains are dated at ~28 Ma. Daphoenus survived
to 27 Ma in the Pacific Northwest in the John Day beds of Oregon (Hunt, 2004).
