Canis Dirus Ashley Livingstone
They lived during the Ice Age and Pleistocene appeared in Eurasia
Origin Wolf ancestors began to develop in the Paleocene, about sixty million years ago. By the Miocene, about twenty million years ago, canines and felines had branched into two separate families. In one ancestor of the wolf,Tomarctus, the fifth toe on the hind leg became vestigal and is evidenced today by the dew claw on both wolves and dogs.
The Dire Wolf was 5 feet long and about 175 pounds. They were slightly larger than the modern gray wolf, but their legs were shorter and sturdier.The head was more robust and the teeth were more massive.
How They Lived that dire wolves may have made their living in similar ways to the modern hyenas. Wolves and coyotes are relatively common large carnivores found in Ice Age sites. In fact, several thousand dire wolves have been found in the asphalt pits at Rancho La Brea in Los Angeles, CA. The coyote, gray wolf, and dire wolf have all been found in paleontological sites in the midwestern U.S.
What Did They Eat They ate horses and bison They were scavengers Their teeth were able to crush bones
For about 1,000,000 years along side their cousins the gray wolves 300,000 years ago they crossed into North America using a land bridge 16,000 years ago they began to die out 10,000 years ago the dire wolf was extinct When Did They Live
Facts Present during the last ice age Hunted in packs Most common in the Rancho La Brea area Largest living wild canine
Other Facts The Dire Wolf and Saber-tooth Cats would fight over food Not a fast runner Some say they looked like an elongated fox, also like a hyena.
