 | | Two distinctive features are recognized, that can be traced back in the fossil record: the sulcal pattern medial to the coronal sulci, and the shape and relative size of the proreal gyrus. |
 | | Four types are described for the first feature: (1) orthogonal: Canis, Lycaon, Cuon, Atelocynus, Speothos, (2) pentagonal: Vulpes, Alopex, Otocyon,Eucyon, (3) parenthesis-like: Dusicyon, Pseudalopex, Chrysocyon, (4) heart-shaped: Urocyon, Cerdocyon, Pseudalopex culpaeus, Nyctereutes. |
 | | On the basis of these features some phylogenetic interpretations are presented: the fossil Asian Nyctereutes is close to Cerdocyon, Speothos is close to Atelocynus, Chrysocyon is not related to Canis, Urocyon differs from Vulpes and Pseudalopex culpaeus differs from the rest of the Pseudalopex species. |
