Pseudodesmatochoerus hoffmani
Taxonomy
Pseudodesmatochoerus hoffmani was named by Schultz and Falkenbach (1954) [genotype]. Its type specimen is F:AM 44912, a partial skeleton (Partial skull with I1-M3, partial mandible with i1-m3, and femur), and it is a 3D body fossil. Its type locality is Big Muddy Creek, which is in an Arikareean terrestrial horizon in Wyoming. It is the type species of Pseudodesmatochoerus.
It was synonymized subjectively with Eporeodon latidens by Lander (1998); it was synonymized subjectively with Mesoreodon chelonyx by Tabrum and Nichols (2001).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. B. Schultz and C. H. Falkenbach 1954 | SKULL: Tendency to be slightly longer, but of approximately same width as examples of P. milleri; medial depression on sagittal crest more pronounced and nasals with greater anterior retraction than in examples of P. milleri; anterior nasal-maxiIIa contact above posterior portion of P 1 ; infraorbital foramen above posterior portion of P8 to an- terior portion pf P4; buila larger and higher than in P. milleri (more like P. wascoensis in this respect) ; postglenoid process more robust than in P. milleri.
MANDIBLE: Approximately equal in size and form to examples of P. milleri; postsymphysis below anterior portion of Pa; condyle more robust than in P. milleri. DENTITION: Series similar to examples of P. milleri, slightly longer and heavier than examples of P. wascoensis, definitely larger than those of P. longiceps. LIMBS:Longer than examples of P. longiceps. | |
| M. S. Stevens et al. 2023 | Differs from P. milleri in a “greater medialdepression of the sagittal crest, a larger bulla, and the moremassive postglenoid process. The anterior nasal maxilla contact,which is located farther posteriorly than in P. milleri, mayindicate a tendency for retraction of the nasals” (Schultz andFalkenbach, 1954, p. 206). |
