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 1949||SKULL:Approximate size of P. carrikeri; smaller than examples of P. macrostegus; supraoccipital wings moderately spread, greatly produced posterior to the occipital condyles; sagittal crest moderately long, high, and sloping down posteriorly; frontals moderately wide; nasal long and rounded laterally, but not noticeably retracted; anterior nasal-maxilla contact P 1 ; zygomatic arch with straight internal posterior border (not hooked as in P. carrikeri), and extending posteriorly beyond the region above the postglenoid process, not to the degree found in examples of P. carrikeri, but more so than in examples of P. (Pseudopromerycochoerus); infraorbital foramen above re- gion of posterior portion of P'; lacrimal fossa larger and deeper than in P. carrikeri,· slight facial depression above premolar region; muzzle joined for short distance; occipital condyles of moderate size; paroccipital process wide at base with slight forward twist; bulla well inflated, high and suboval in outline, extending downward beyond the inferior border of the postglenoid process; postglenoid process robust and high; posterior palate projecting posteriorly beyond M3 (not to the extent found in examples of P. superbus chelydra).
MANDIBLE:Moderately robust; ramus of same depth until reaching a point below Ma; inferior border straight to a point below the posterior of Ma, then curving gradually downward.
DENTITION:Equal to smaller examples of P. carrikeri; average smaller than average examples of P. carrikeri or P. latidens.
