Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. B. Schultz and C. H. Falkenbach 1956 | Oreodonts of very small to small size [largest examples approaching those of Miniochoerus (Paraminiochoerus) gracilis,
p. 413, the smallest species of Miniochoerinae]; skulls mesocephalic; supraoccipital wings small and moderately spread, incorporated into a fan-shaped occipital region; orbits roundish, moderately small for size of skulls (see discussion concerning orbits, p. 457) ; temporal ridge moderately prominent, extending forward and outward to and above postorbital process of frontal; auditory bullae well inflated, subround outline [longer anteroposteriorly than transversely, decidedly different from the small (minute) examples of Miniochoerinae and Merycoidodon] ; P 8 subtriangular in outline, anterior portion reduced in size (decidedly more reduction than in examples of Miniochoerinae or Merychyinae, more like Protoreodon from the Eocene) ; molars with deep fossettes. |
