Scientists Say: Dire wolf
Dire wolf (noun, “DIE-er wolf”)
This is a species of wolf (Canis dirus) that lived in North America from about 300,000 to 12,000 years ago. Fossils from these animals suggest that dire wolves could have weighed as much as 67 kilograms (148 pounds) and grow up to 1.8 meters (or 6 feet) long. That makes them similar in size to the largest of modern wolves. Don’t expect to ever run across one, though. Dire wolves are now extinct.
In a sentence

Fossils show it would have weighed up to 67 kilograms (148 pounds) and sported a body that would have spanned up to 1.8 meters (6 feet) from snout to tail tip. It ate a varied diet that could have included big prey such as horses, although bison, camels, mastodons and sloths also were eaten (probably when taken down by a pack of these wolves.
