Diagnosis
ReferenceDiagnosis
C. B. Schultz and C. H. Falkenbach 1949SKULL:Smaller than in average examples of P. carrikeri from the same formation; sagittal crest slightly less in length and height than in P. (Parapromerycochoerus) macro- stegus; moderately wide frontals; nasal with more anterior retraction than in P. carrikeri; anterior nasal-maxilla contact above pos- terior portion of P 1 ; zygomatic arch with straight posterior border, not hooked as in examples of P. carrikeri; postglenoid process not so robust as that found in examples of
P. (P.) macrostegus. MANDIBLE:Comparatively light; inferior
border increasing in depth posteriorly, with slight downward curve posterior of Ma, curve decidedly more abrupt in P. (P.) macroste- gus.
DENTITION:Average length of dental se- ries less than in examples of P. carrikeri, P. (Parapromerycochoerus) macrostegus, and P.
(P.) macrostegus furlongi.
