R. M. Hunt 2011 | Wolf-sized species of Temno- cyon (basilar skull length ,25 cm), distin- guished from T. altigenis and T. subferox by much larger size, from T. macrogenys by smaller size; differs from similarly sized T. ferox by greater inflation of the frontal paranasal sinuses (relative to braincase width, table 7) and by different form and propor- tions of p4–m2 and M1–2 (tables 2, 3), including a more lingually extended M1–2 with less expansion of M1 protocone region (ratio A/B, table 6), a much larger M2 and m2, a longer m2 (ratio E/F), and by a more robust, wider p4. Temnocyon fingeruti differs from T. percussor in its much smaller M1 (in the upper dentition of T. percussor only M1 survives), more elongate m1–2, stronger m1 metaconid, and larger, rectangular m2 with vestigial metaconid and more developed paraconid, and by the p4/m1 ratio (0.78 in T. fingeruti vs. 0.84 in both T. percussor and T. ferox). Temnocyon fingeruti differs from T. altigenis, T. subferox, and probably T. ferox in P4 proportions (ratio C/D, table 6); P4 is not known in T. percussor and T. macrogenys. |
