Skeleton of Dire Wolf (Canis dirus). The Dire Wolf is an extinct carnivorous mammal of the genus Canis, and was most common in North and South America during the Pleistocene. Although it was closely related to the Grey Wolf, which is of Eurasian origin, the Dire Wolf evolved on the North American continent, along with the Coyote. The Dire Wolf and the Grey Wolf co-existed in North America for about 100,000 years. Approximately 10,000 years ago, the Dire Wolf became extinct, along with most other North American megafauna. The vast majority of fossils recovered have been from the La Brea Tar Pits in California. Shown howling at the Royal Tyrrell Museum, Drumheller, Alberta, Canada.
