In the TV series Game Of Thrones, a number of characters have a dire wolf companion. On the show, these wolves are depicted as large, fierce, and loyal. Game of Thrones may have taken some liberties, but dire wolves were actual ancient animals.
Real dire wolves — called Canis dirus, or “fearsome dogs” — existed from about 125,000 to 10,000 years ago in present-day North and South America. Though similar to gray wolves, dire wolves are genetically different.
Slightly bigger than gray wolves and with reddish fur, dire wolves weighed around 130 pounds and measured about six feet long. Like the dire wolves of fiction, Canis dirus also had formidable jaws that helped them kill.
The dire wolves went after a variety of prey. They killed horses, bison, and even young mammoths when they could get it. By springing on their prey and latching on with their jaws, dire wolves dragged animals down so that they could kill them. As such, their fossils are often found with neck injuries.
Sometimes, they actually competed with saber-toothed cats to make the kill.
To date, thousands of dire wolf skeletons have been found at the La Brea Tar Pits in California. Like the Smilodon, dire wolves often chased their prey with a bit too much enthusiasm and got caught in the tar.
But it wasn’t the La Brea Tar Pits alone that killed off the last of the dire wolves. It seems likely that these wolves died off because their prey did. Lacking slow-moving animals to kill — and unable to catch up with faster ones — the dire wolves went extinct.
They live on in the world of fiction, however. Dire wolves have enjoyed a renaissance thanks to George R.R. Martin’s book series and the Game Of Thrones TV show.
