Beringian wolf : ウィキペディア英語版
Beringian wolf

The Beringian wolf was a hypercarnivorous ecomorph of gray wolf which inhabited eastern Beringia (modern day Alaska) during the Late Pleistocene and early Holocene. It was similar in size to other Pleistocene gray wolves and modern Alaskan wolves, but had a shorter, broader palate, with large carnassials relative to its overall skull size. This adaptation allowed it to predate and scavenge on Pleistocene megafauna.
== Lineage ==
In 1975, a study was made of ancient canid remains dated to the Late Pleistocene and early Holocene that had been uncovered by miners decades earlier around Fairbanks, Alaska. These were identified as ''Canis lupus'' and described as "short-faced wolves". The collection was separated into those specimens that looked more wolf-like, and those that looked more dog-like and in comparison to the skulls of Eskimo dogs from both Greenland and Siberia thought to be their forerunners.
