Despite this increase in skull size, the Dire Wolf shows a smaller brain cavity. Dire Wolves primarily ate wild horses and bison with an occasional feast on mastodon and giant ground sloths.  Nowak, Kurtén, and Annalisa Berta proposed that C. dirus was not derived from C.  The finds at San Josecito Cave and El Cedazo have the greatest number of individuals from a single locality. In general, the skull of this species looks like a very large wolf skull. Dire wolf body size had decreased between the start of the Last Glacial Maximum and near its ending at the warm Allerød oscillation.  The largest northern wolves today have a shoulder height of 38 in (97 cm) and a body length of 69 in (180 cm). Many dire wolf fossils show signs of horrific injuries including completely broken forelegs and partially crushed skulls. Remarkably, however, many of these injuries actually healed with some of the fossils displaying evidence that the wolves in question lived for months and even years after the injury happening. Furthermore, many of these specimens were recovered from Rancho La Brea, leading to the fact that the dire wolves in question died as a result of being stuck in the tar and not of the injury. , In 1876 the zoologist Joel Asaph Allen discovered the remains of Canis mississippiensis (Allen 1876) and associated these with C. dirus (Leidy 1858) and Canis indianensis (Leidy 1869). These finding indicates that tooth breakage was related to hunting behavior and the size of prey. Poor Grey Wind. In "Dire Wolf," Jerry Garcia croons "don't murder me, I beg of you, please don't murder me" to a dire wolf ("600 pounds of sin") that has somehow sneaked in through his living-room window. The results showed that the 15,000 YBP dire wolves had three times more tooth breakage than the 13,000 YBP dire wolves, whose breakage matched those of nine modern carnivores. , Dire wolf remains have been found across a broad range of habitats including the plains, grasslands, and some forested mountain areas of North America, and in the arid savannah of South America. Nowak. This means that the female Dire Wolf did not have specifically feminine traits and both male and female Dire Wolf’s had similar teeth size and bone structure. One pit contained fossil dire wolves dated 15,000 YBP and another dated 13,000 YBP. The fossil record suggests C. dirus originated around 250,000 YBP in the open terrain of the mid-continent before expanding eastward and displacing its ancestor C. R. Knight. A temporary channel between the glaciers may have existed that allowed these large, Alaskan direct competitors of the dire wolf, which were also adapted for preying on megafauna, to come south of the ice sheets.

Canines are the teeth most likely to break because of their shape and function, which subjects them to bending stresses that are unpredictable in both direction and magnitude. Dire wolves were absent north of 42°N latitude in the Late Pleistocene; therefore, this region would have been available for Beringian wolves to expand south along the glacier line. A display of some of the thousands of Dire Wolf skulls found in La Brea Tar Pits. lupus. 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).  Stable isotope analysis of dire wolf bones provides evidence that they had a preference for consuming ruminants such as bison rather than other herbivores but moved to other prey when food became scarce, and occasionally scavenged on beached whales along the Pacific coast when available.
