Mogollon mountain wolf

The Mogollon mountain wolf (Canis lupus mogollonensis) is an extinct subspecies of gray wolf whose range once included Arizona and New Mexico.

It is darker than its more northern cousins, and has a highly arched frontal bone.

[2] This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005).

This was accepted by the US Fish and Wildlife Service in 1982 and a "zone of subspecies intergradation" was recognized soon thereafter, extending from the southern Rocky Mountains to the northern tip of the Mexican wolf's range.
