The dire wolf (Aenocyon dirus[10] / iːˈnɒsaɪ.ɒn ˈdaɪrəs /) is an extinct canine. The dire wolf lived in the Americas (with a possible single record also known from East Asia) during the Late Pleistocene and Early Holocene epochs (125,000–9,500 years ago). The species was named in 1858, four years after the first specimen had been found.
† 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).
As a result, the study found that the correct binomial name of the dire wolf is Aenocyon dirus, as proposed by Merriam in 1918. 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. [51]
Among the prehistoric Pleistocene species associated with the La Brea Tar Pits are Columbian mammoths, dire wolves, short-faced bears, American lions, ground sloths (predominantly Paramylodon harlani, with much rarer Megalonyx jeffersonii and Nothrotheriops shastensis) and the state fossil of California, the saber-toothed cat (Smilodon fatalis).
During the Late Pleistocene, the more southerly occurring dire wolf (Aenocyon dirus) had the same shape and proportions as the Yukon wolf, [33] [34] but the dire wolf subspecies A. dirus guildayi is estimated to have weighed on average 60 kg (130 lb), and the subspecies A. dirus dirus on average 68 kg (150 lb), with some specimens being larger ...
Depth. 85 feet (26 m) Elevation. 4,560 feet (1,390 m) Natural Trap Cave is a pit cave in the Bighorn Mountains, in northern Wyoming, United States. Excavations in the cave are an important source of paleontological information on the North American Late Pleistocene, due to a rich layer of fossils from animals that became trapped in the cave. [1]
The wolf (Canis lupus; [b] pl.: wolves), also known as the gray wolf or grey wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo , though gray wolves, as popularly understood, only comprise naturally-occurring wild subspecies.
Armbruster's wolf (Canis armbrusteri) is an extinct species that was endemic to North America and lived during the Irvingtonian stage [1] of the Pleistocene epoch, spanning from 1.9 Mya —250,000 years BP. [2] It is notable because it is proposed as the ancestor of one of the most famous prehistoric carnivores in North America, the dire wolf ...
