The mandibles of canids are buttressed behind the carnassial teeth to crack bones with their post-carnassial teeth (molars M2 and M3). A study found that the modern gray wolf and the red wolf (C. rufus) possess greater buttressing than all other extant canids and the extinct dire wolf. This indicates that these are both better adapted for ...
The dire wolf was about the same size as the Yukon and Northwestern wolves, the largest modern gray wolves (Canis lupus). Its skull and dentition matched those of the gray wolf, but its teeth were larger with greater shearing ability, and its bite force at the canine tooth was the strongest of any known Canis species.
English: Dentition of an Ice Age wolf showing functions of the teeth. References for the function of teeth used to predate on Late Pleistocene megafauna can be found in Leonard 2007 for the Beringian wolf or Van Valkenburgh 1993 for the Dire wolf.
A study of the estimated bite force at the canine teeth of a large sample of living and fossil mammalian predators, when adjusted for their body mass, found that for placental mammals the bite force at the canines was greatest in the extinct dire wolf (163), followed among the modern canids by the four hypercarnivores that often prey on animals ...
Gray wolf [31] [35] Canis lupus: 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 ...
Nowak compared the orbital angles of four North American canines (including the Indian dog) and produced the following values in degrees: coyote-42.8, wolf-42.8, dog-52.9 dire wolf-53.1. The orbital angle of the eye socket was clearly larger in the dog than in the coyote and the wolf; why it was almost the same as that of the dire wolf was not ...
