Diagnosis
ReferenceDiagnosis
D. R. Prothero 1996he Family Camelidae is united by the following shared characters that distinguish it from the remaining Tylopoda, and all other artiodactyls: fully selenodont, transversely compressed upper molars that are relatively high- crowned (compared to other primitive Tylopoda), with straight ectolophs, and with fossettes that are closed anteriorly and posteriorly after moderate wear. Relatively long, narrow rostrum. Postorbital processes well developed, and nearly or completely closed. Inflated tympanic bulla filled with cancellous bone and indented by a deep tympanohyal groove. Angular process on mandible with a distinctive dorsal "hook." Long, unfused to fused, distally divergent middle metapodials with metacarpals II and IV and metatarsals II and V reduced to nodules. Metatarsals III and IV have flattened dorsal surfaces and their distal keels do not extend to the dorsal side. Fibular facet on the calcaneum has a proximal convexity and a dorsal concavity.
