Hypsiops is an extinct genus of oreodont of the superfamily Merycoidodontoidea, family Merycoidodontidae endemic to North America during the Late Oligocene-Early Miocene epochs (24.8—16.3 mya), existing for approximately 8.5 million years.[1]

Taxonomy[edit]

Hypsiops was named by Schultz and Falkenbach (1950). It was assigned to Merycoidodontidae by Schultz and Falkenbach (1950) and Lander (1998).[2]

Morphology[edit]

Two specimens were examined by M. Mendoza for body mass. Specimen one was estimated to have a weight of 168.6 kg (371.6 lbs). Specimen two was estimated to have a weight of 223.0 kg (491.6 lbs).[3]

Fossil distribution[edit]

Fossils have been uncovered throughout the western U.S. in Oregon, Montana, Wyoming, as well as Nebraska.

Species[edit]

H. bannackensis (syn. Pseudomesoreodon boulderensis, Pseudomesoreodon rolli), H. breviceps (syn. H. johndayensis, Pseudomesoreodon rooneyi, Ticholeptus brachymelis, Ticholeptus petersoni.
