Did giant dogs exist?
An international team of scientists has just identified what they believe is the world’s first known dog, which was a large and toothy canine that lived 31,700 years ago and subsisted on a diet of horse, musk ox and reindeer, according to a new study.
Are Epicyon extinct?
Epicyon (“more than a dog”) is a large, extinct, canid genus of the subfamily Borophaginae (“bone-crushing dogs”), native to North America.
Why do we have big cats and not big dogs?
Big cats mostly hunt alone and rely on a short burst of speed to catch their prey, and swipes from their claws to bring it down.

Dogs are not descended from one prehistoric animal. They are descended from a genepool. A better metaphor than pool might be the strongly flowing mighty gene river, always there and always in constant motion. What happened to the prehistoric Big Dogs?
How many years did it take for dogs to evolve?
40 Million Years of Dog Evolution. But there are two big differences in this case: first, dogs are carnivores, and the evolution of carnivores is a twisty, serpentine affair involving not only dogs, but prehistoric hyenas, bears, cats, and now-extinct mammals like creodonts and mesonychids. And second, of course,…
