The dire wolf (Aenocyon dirus [10] / iː ˈ n ɒ s aɪ. ɒ n ˈ d aɪ r ə s /) is an extinct canine. The dire wolf lived in the Americas during the Late Pleistocene and Early Holocene epochs (125,000–9,500 years ago). A putative, controversial fossil was recently reported from northeast China, but other researchers questioned the taxonomic ...
Just before the appearance of the dire wolf (Aenocyon dirus), North America was invaded by the genus Xenocyon, which was as large as A. dirus and more hypercarnivorous. The fossil record shows them as rare and it is assumed that they could not compete with the newly derived A. dirus. [4]
Aenocyon dirus: North America and western South America Most recent remains at Talara, Peru dated to 7320-6840 BCE; however this date is uncalibrated and the age of the remains could be older. Other late remains from Luján, Argentina were older than the most recent stratigraphical section dated to 9050-8050 BCE. [33] Falkland Islands wolf
The extinct dire wolf (Aenocyon dirus) reached 1.5 m (4.9 ft) in length and weighed between 50 and 110 kg (110 and 243 lb). [42] [172] The largest wolf (Canis lupus) subspecies ever existed in Europe is the Canis lupus maximus from the Late Pleistocene of France.
However, a 2021 genetic study of the dire wolf (Aenocyon dirus), previously considered a member of Canis, found that it represented the last member of an ancient lineage of canines originally indigenous to the New World that had diverged prior to the appearance of Canis, and that its lineage had been distinct since the Miocene with no evidence ...

By 1912 he had found a skeleton sufficiently complete to be able to formally recognize these and the previously found specimens under the name C. dirus (Leidy 1858) [citation needed]. Canis dirus, [43] or as it is now widely recognized, Aenocyon dirus, lived in the late Pleistocene to early Holocene in North and South America. [44]
† Aenocyon dirus: Over 4.000 individuals A large wolf-like carnivore, the dire wolf was the most common predator found in the tar pits of La Brea, outnumbering the slightly smaller grey wolf over 100-fold. They could reach a weight of approximately 68 kg (150 lb).
