Pseudodesmatochoerus milleri
Taxonomy
Pseudodesmatochoerus milleri was named by Schultz and Falkenbach (1954). Its type specimen is F:AM 33304, a skull (Skull with I1-M3 and mandible with i1-m3), and it is a 3D body fossil.
It was synonymized subjectively with Merycoidodon major by Stevens and Stevens (1996); it was synonymized subjectively with Eporeodon major by Lander (1998).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. B. Schultz and C. H. Falkenbach 1954 | SKULL: Medium size; tendency to be slightly smaller than examples of P. koffmani, larger than in P. longiceps; supraoccipital wings with less spread than in P. longiceps; sagittal crest with slightly depressed medial region, not so pronounced as in examples of P. koffmani; nasals long and light, with slight anterior retraction, less retraction than in latter species; anterior nasal-maxilla contact above P1, slightly more anterior than in examples of P. koffmani; infraorbital foramen above PLP 4; bulla of moderate size, smaller than other examples of genus; post-glenoid process more peg-shaped than in examples of P. kojfmani (closer to that of P. longiceps in this respect, but with less height).
MANDIBLE: Postsymphysis below anterior portion of Pa; posterior border of ascending ramus lighter than in P. longiceps. · DENTITION: Series approximately same size as examples of P. koffmani, larger than in P. longiceps, slightly longer than in P. wascoensis; more robust than in latter two species. LIMBS: (Unknown). | |
| M. S. Stevens et al. 2023 | Differs from P. hoffmani in less depressed sagittalcrest, a smaller bulla, and the more gracile postglenoid process.The anterior nasal maxilla contact is not as far posteriorly thanin P. hoffmani. |
