Cerdocyon (crab-eating fox)
Mammalia - Carnivora - Canidae
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||As indicated by Ted- ford et al. (1995), the synapomorphy that unites Cerdocyon with Atelocynus and Speothos and distinguishes it from more plesiomorphic South American Canini (Du- sicyon, Pseudalopex, and Lycalopex) is the further expansion of the angular process of the mandible and enlargement of the fossa for the inferior ramus of the median ptery- goid muscle. Additionally, other synapomor- phies specifically unite Cerdocyon and its sister taxon Nyctereutes such as presence of a subangular lobe of the mandible and short and recurved canines of small diameter. Cerdocyon differs from most cerdocyonines in that its palate does not extend behind the toothrow. The same is true for fossil species of Nyctereutes, but in the living N. procyo- noides the palate is long.|
