Mammalia - Artiodactyla - Merycoidodontidae
It was synonymized subjectively with Merycoides harrisonensis by Lander (1998).
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|C. B. Schultz and C. H. Falkenbach 1950||SKULL:Intermediate in size between P. typus and P. stouti; frontals slightly rounded laterally; nasals retracted anteriorly to a point above posterior portion of P1, with greater retraction than in examples of P. typus; anterior nasal-maxilla contact above the posterior portion of P2; supraorbital foramen at posterior end of a deep, narrow, elongated, slot-like depression (not an oblong vacuity as in P. typus or a round foramen as in P. stouti'), with suggestion of a groove extending forward and downward from it to
facial vacuity; zygomatic arch with a gradual rise posteriorly, extending to a point above posterior border of postglenoid process; in- fraorbital foramen above posterior portion of P 8 ; facial vacuity 2 ; bulla with inferior surface more depressed towards basioccipital than in P. typus; postglenoid process moderately heavy with sloping external border.
MANDIBLE:Intermediate in size between examples of P. typus and P. stouti; approximately equal in size to examples of Hypsiops luskensis.
DENTITION: Superior and inferior series intermediate in over-all length between P. typus and P. stouti, approximately equal in size to examples of H. luskensis; C/ and P1 large; axis of PLP 3 parallel to alveolar border; P2 and Pa set at slight angle to alveolar border; P2 with weak posterior intermediate crest; Paand P, each with moderately prominent posterior intermediate crest.
LIMBS:Decidely longer than examples of P. typus; lighter, but approximately same length as examples of P. stouti.
