How long did the dire wolf live during Pleistocene age?

Dire wolves ( Canis dirus) inhabited North America during the Pleistocene epoch, which lasted from about 2.5 million years ago to about 11,700 years ago.

Fossil records indicate that dire wolves first appeared around 1.8 million years ago and roamed the continent until approximately 10,000 years ago, just before the end of the Pleistocene epoch. Therefore, dire wolves lived for roughly 1.7 million years during the Pleistocene age.
