R. H. Tedford et al. 2009 | A synapomorphy that U. citri- nus shares with U. galushai is rounded subangular lobe on the mandibular ramus. Pleistocene and Recent species of Urocyon have a distinctly angular subangular process. We have been unable to recognize any autapomorphies for this taxon, although it clearly belongs to the genus as discussed below.
Differs from U. galushai in the following plesiomorphies: smaller premolars, and larg- er m2 with longer trigonid, stronger para- cristid and small paraconid, longer bicuspid talonid with entoconulid, and distinct hypo- conulid. Differs from U. minicephalus in the following plesiomorphies: less robust p4; m1 more elongate; and m2 relatively larger, trigonid longer, paraconid small, and talonid longer with distinct entoconulid. Differs from U. c. floridanus in the following plesiomor- phies; slenderer p4; m1 narrower, metaconid relatively smaller, protostylid weaker, ento- conulid stronger; and m2 lingual border less convex and buccal border less concave, trigonid longer, paracristid stronger, metaco- nid and protoconid smaller with protoconid situated more posteriorly and nearly opposite metaconid; and talonid relatively wider. Differs from U. c. scotti in the following plesiomorphies: larger m2 with longer trigo- nid, stronger paracristid, and small paraco- nid, and wider talonid. |
