Size comparison with a human. The average dire wolf proportions were similar to those of two modern North American wolves: the Yukon wolf (Canis lupus pambasileus) [56] [13] and the Northwestern wolf (Canis lupus occidentalis). [56] The largest northern wolves today have a shoulder height of up to 38 in (97 cm) and a body length of 69 in (180 cm).
Epicyon had a massive head and powerful jaws that were well adapted for bone-crushing, with enlarged fourth premolars like some hyenas, giving its skull a lion-like shape rather than having a skull similar in shape to that of a wolf; the adaptation would have allowed Epicyon to scavenge as well as hunt, giving it access to the nutritious marrow other contemporary carnivores couldn't access.
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 ...
Another huge animal of this group was Uintatherium, with skull length of 76 cm (30 in), 1.5 m (4 ft 11 in) tall at the shoulder, [151] 4 m (13 ft) in length and 2.25 t (2.48 short tons), the size of a rhinoceros. [152] Despite their large size, Eobasileus as well as Uintatherium had a very small brain. [151] [152]
† Dire wolf [31] † 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).
The Northwestern wolf is also one of the longest wolf subspecies, as its length usually ranges from 5 to 6 ft (152–183 cm) and can reach as long as 7 ft (213 cm). [ 13 ] [ 14 ] In comparison, the mean adult weights of its nearest rivals in size, the Eurasian wolf ( C. l. lupus ) and the Interior Alaskan wolf ( C. l. pambasileus ), was ...
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 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 .
