The thylacine was able to open its jaws to an unusual extent: up to 80 degrees. [46] This capability can be seen in part in David Fleay's short black-and-white film sequence of a captive thylacine from 1933. The jaws were muscular, and had 46 teeth, but studies show the thylacine jaw was too weak to kill sheep.
The skull was exactly equal in size to that of an Arctic wolf, the only notable differences being that the sectorial molar was slightly larger and the lower border of the jaw was more convex. It was positively identified as being that of a wolf by its low and contracted forehead.
Skull of the dire wolf [80] A study of the cranial measurements and jaw muscles of dire wolves found no significant differences with modern gray wolves in all but 4 of 15 measures. Upper dentition was the same except that the dire wolf had larger dimensions, and the P4 had a relatively larger, more massive blade that enhanced slicing ability at ...
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 predation and scavenging on Pleistocene megafauna possible. The Beringian wolf preyed most often on horse and steppe bison, and also on caribou, mammoth, and woodland ...
In 2021, a mitochondrial DNA analysis of North American wolf-like canines indicates that the extinct Late Pleistocene Beringian wolf was the ancestor of the southern wolf clade, which includes the Mexican wolf and the Great Plains wolf.
