context_page_description: The Beringian wolf is an extinct type of wolf that lived during the Ice Age. It inhabited what is now modern-day Alaska, Yukon, and northern Wyoming. Some of these wolves survived well into the Holocene. The Beringian wolf is an ecomorph of the gray wolf and has been comprehensively studied using a range of scientific techniques, yielding new information on the prey species and feeding behavior of prehistoric wolves. It has been determined that these wolves are morphologically distinct from modern North American wolves and genetically basal to most modern and extinct wolves. The Beringian wolf has not been assigned a subspecies classification and its relationship with the extinct European cave wolf is not clear.
  The Beringian wolf was similar in size to the modern Alaskan Interior wolf and other Late Pleistocene gray wolves but more robust and with stronger jaws and teeth, a broader palate, and larger carnassial teeth relative to its skull size. In comparison with the Beringian wolf, the more southerly occurring dire wolf was the same size but heavier and with a more robust skull and dentition.
context_section_description: Extinction is the result of the elimination of the geographic range of a species with a reduction of its population size down to zero. The factors that affect biogeographic range and population size include competition, predator-prey interactions, variables of the physical environment, and chance events.
