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.

Diagnosis
ReferenceDiagnosis
C. B. Schultz and C. H. Falkenbach 1954SKULL: 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.
