Wolf is considered to be the direct ancestor to the more well-known
wolf, as indicated by gradual changes in its bone structure
took on identifiable dire wolf features. Although it gave rise to the
dire wolf, Armbruster's wolf lost ground to its larger descendent being
steadily pushed towards the East coast, until the latest surviving
members being known from Florida during the latter half of the Ionian
The overall morphology for Armbruster's wolf is quite similar to its descendent the dire wolf, save for the skull which is narrower. This may indicate that Armbruster's wolf had a smaller bite force. Another wolf, Canis falconeri (Falconer’s Wolf), is also considered to be closely related to Armbruster’s wolf.
