Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. M. Hunt 2011 | Smallest and most plesio- morphic North American temnocyonine spe- cies distinguished from all other species of Temnocyon by small size and range of m1 lengths, 17.4–19.5 mm (table 2), and from T. subferox, T. fingeruti, and T. percussor by either M1 or P4 proportions (dental ratios A/B, C/D, table 6); from T. ferox and the huge T. macrogenys by much smaller size. Ratio of m1/m2 lengths, 1.67–1.83, indicating a short m2 relative to m1, thus distinct from species of Mammacyon (1.57, 1.61) but not from other Temnocyon species (ratios of 1.62–1.79) or Delotrochanter (1.64–1.69). Basilar length of skull, ,16–18 cm relative to 21–30 cm for other Temnocyon species (table 7); frontal sinuses moderately inflated. |
