Daphoeninae is an extinct subfamily of dog-like, terrestrial carnivore, which belonged to the family Amphicyonidae of the suborder Caniformia. The group inhabited North America from the Early Eocene subepoch to the Early Miocene subepoch 42—16.3 Mya, existing for approximately 25.7 million years.[1]
Fossil distribution
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.[2] Other sites include: Alachua County, Florida (Whitneyan) estimated at 31.1—24.3 Ma., Tecuya Canyon, California (Arikareean age) 30.8—20.6 Ma., Haystack Member Formation, Wheeler County, Oregon (Hemingfordian) 20.6—16.3 Ma., Lac Pelletier, Alberta, Canada (Duchesnean) ~42 Ma.
