Phenacocoelus is an extinct genus of oreodont of the family Merycoidodontidae, subfamily Merycoidodontinae, endemic to North America during the Late Oligocene-Early Miocene subepochs (24.8—20.6 mya), existing for approximately 4.2 million years.[1]
Taxonomy
Phenacocoelus was named by Peterson (1907). Its type is Phenacocoelus typus. It was assigned to Merycoidodontidae by Peterson (1907) and Lander (1998).[2][3]
Morphology
A single specimen was examined by M. Mendoza for body mass and was estimated to have a weight of 73.0 kg (160.9 lbs).[4]
Fossil distribution
Fossils have been uncovered in eastern Wyoming and western Nebraska
Species
Phenacocoelus typus (syn. P. munroensis).
