The Wikipedia article of the day for December 1, 2017 is Beringian wolf.
The Beringian wolf (Canis lupus) lived during the last Ice Age in what is now Alaska, the Yukon, and northern Wyoming. The wolf was more robust, with stronger jaws and teeth, than other Late Pleistocene gray wolves and the comparably sized modern Yukon wolf (Canis lupus pambasileus), but not as strong as the dire wolf. The unique adaptations of the Beringian wolf’s skull and dentition allowed it to produce large bite forces while grappling with large prey and predating and scavenging on Pleistocene megafauna. The wolf has been comprehensively studied, yielding new information on the prey species and feeding behavior of prehistoric wolves. The Beringian wolf preyed most often on horse and steppe bison, and also on caribou, mammoth, and woodland musk ox. The species survived well into the Holocene before its extinction at the close of the Ice Age, when cold and dry conditions abated and much of its prey also went extinct. The remains of ancient wolves with similar skulls and dentition have been found in western Beringia (north-east Siberia).
