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 ...
Diagram of a wolf skull with key features labelled. In mammals, the rostrum is that part of the cranium located in front of the zygomatic arches, where it holds the teeth, palate, and nasal cavity. [6] Additionally, the corpus callosum of the human brain has a nerve tract known as the rostrum.
The wolf was described as "white with black-tipped hair along the ridge of the back". It is a large rangy wolf, with long narrow skull, slender rostrum and extremely large upper and lower carnassials. [7]
The East Beringian wolf was identified as an ecomorph of the grey wolf (Canis lupus) with a skull morphology that was adapted for hunting and scavenging megafauna. None of the 16 mtDNA haplotypes recovered from a sample of 20 of the wolves was shared with any modern grey wolf, but similar haplotypes were found in Late Pleistocene Eurasian grey ...
It was named in 1912 by Gerrit Smith Miller Jr., who noted that it closely approaches the Great Plains wolf in skull and tooth morphology, though possessing a narrower rostrum and palate. [4] It is a large, white-colored wolf closely resembling C. l. pambasileus, though lighter in color. [5]
The gray wolf (C. lupus), the Ethiopian wolf (C. simensis), eastern wolf (C. lycaon), and the African golden wolf (C. lupaster) are four of the many Canis species referred to as "wolves". [37] Species that are too small to attract the word "wolf" are called coyotes in the Americas and jackals elsewhere. [ 38 ]
The Kenai Peninsula wolf was dependent on the very large moose of the region (hence the trinomial alces, or moose) and Goldman proposed that its large size was an adaption to this. [13] [14] The Smithsonian Institution has a skull specimen of the Kenai Peninsula wolf, numbered as USNM 147471. [15]
The red wolf has been compared by some authors to the greyhound in general form, owing to its relatively long and slender limbs. The ears are also proportionately larger than the coyote's and gray wolf's. The skull is typically narrow, with a long and slender rostrum, a small braincase and a well developed sagittal crest.
