If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|R. H. Tedford et al. 2009||Leptocyon differs from Vulpes in possession of the following primi- tive characters: greater postorbital constriction; I1–I3 with medial cusplets; M1 and M2 with stronger parastyle; m1 hypoconulid absent, its entoconid relatively smaller and enlarged only in most derived species; m2 with weaker anterolabial cingulum and meta- conid smaller than or equal in size to protoconid in less derived species, postpa- rietal foramen still present in early species; humerus with entepicondylar foramen; ulna and fibula short and more robust with larger distal articular facets for radius and tibia; radius with distal exostosis in early species (Wang and Rothschild, 1992); tibia with longer anteroproximal crest, less anteriorly and distally extended proximolateral and proximomedial articular surfaces for femur; relatively larger entocuneiform and well- developed functional metatarsal I with two phalanges.|
