Diagnosis
ReferenceDiagnosis
R. M. Hunt 2011Wolf-sized species of Temno- cyon (basilar skull length, ,26 cm), distin- guished from T. altigenis and T. subferox by much larger size, from T. macrogenys by much smaller size, and from the Mammacyon obtusidens–M. ferocior group by retention of the m1 metaconid and possession of a short m2 relative to m1 (ratio E/F, ,1.6 in Mammacyon; ,1.8 in T. ferox). T. percussor is distinguished from T. ferox by its taller, broader p3–4 and by its larger more robust m1–2 and M1 (tables 2, 3). T. ferox and T. percussor share a similar m1–2 form but T. percussor represents a larger species. T. fingeruti differs from T. ferox in its more elongate, narrower m1, longer m2, dispro- portionate size of M1–2 (small M2 relative to M1 in T. ferox; large M2 in T. fingeruti); dental ratios (table 6); and more inflated
frontal region.
