In comparison with the Beringian wolf, the more southerly occurring dire wolf (Aenocyon dirus) was the same size but heavier and with a more robust skull and dentition. The unique adaptation of the skull and dentition of the Beringian wolf allowed it to produce relatively large bite forces, grapple with large struggling prey, and therefore made ...
True members of Canis, namely the gray wolf and coyote, likely only arrived in the New World during the Late Pleistocene, where their dietary flexibility and/or ability to hybridize with other canids allowed them to survive the Quaternary extinction event, unlike the dire wolf. [14] Xenocyon (strange wolf) is an extinct subgenus of Canis. [15]
The dire wolf shared its habitat with the gray wolf, but became extinct in a large-scale extinction event that occurred around 11,500 years ago. It may have been more of a scavenger than a hunter; its molars appear to be adapted for crushing bones and it may have gone extinct as a result of the extinction of the large herbivorous animals on ...
Another study of the Lake Taimyr wolf found that its comparatively small size and characters of the cheekteeth and skull raised the possibility that it might have been a domesticated or semi-domesticated animal. [43]: 1033 The increased skull width in comparison to extant wolves indicated pronounced development of the temporalis muscles.
Diagram of a wolf skull with key features labelled. The origin of dogs is couched in the biogeography of wolf populations that lived during the Late Pleistocene. [1] The fossil record shows evidence of changes in the morphology and body size of wolves during the Late Pleistocene, which may be due to differences in their prey size.
The long-term isolation of the dire wolf lineage implies that other American fossil taxa, including C. armbrusteri and C. edwardii, may also belong to the dire wolf's lineage. [13] In the 2024 study, the Armbruster's wolf is considered as a species of Aenocyon , while C. edwardii is considered more closely related to the modern coyote .
