Dire wolf fossils from Mexico and Peru show a similar pattern of breakage. A 1993 study proposed that the higher frequency of tooth breakage among Pleistocene carnivores compared with living carnivores was not the result of hunting larger game, something that might be assumed from the larger size of the former.
Modern wolves are notably rarer at La Brea than the slightly larger dire wolves. One particular fossil preserves the femur of a wolf that survived a traumatic injury. The nature of the fossil suggests that the wolf's leg was either broken and developed a pseudarthrosis or that the leg was entirely amputated and healed. Such an injury could have ...
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 ...
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 .
[citation needed] This long-term isolation of the dire wolf lineage implies that other American fossil canines, including C. armbrusteri and C. edwardii, may belong to the same lineage as Aenocyon. [11] In a 2024 study, Armbruster's wolf was considered as a species of Aenocyon, while Canis edwardii was considered more closely related to the ...
Late Pleistocene to recent bones from 20 species of mammals and five bird species were recovered, including a dire wolf, ancient horse, and mammoth. Ms. Rushin's Master's thesis "Interpretive and Paleontologic Values of Natural Trap Cave, BigHorn Mountains, Wyoming" (1973) addressed the interpretive, anthropologic, paleontologic, and geologic ...
