What was the prehistoric dog?
Hesperocyon. Dogs were only domesticated about 10,000 years ago, but their evolutionary history goes back way further than that–as witness one of the earliest canines yet discovered, Hesperocyon, which lived in North America a whopping 40 million years ago, during the late Eocene epoch.
Why did the bone crushing dogs go extinct?
According to an analysis of the fossil record of North American fossil carnivorans, the decline of borophagines from a diversity of about 30 species 15 million years ago to extinction was largely driven by competition with felids and canines.
What dinosaur did dogs descend from?
The First Canids: Hesperocyon and the “Bone-Crushing Dogs” Paleontologists agree that the late Eocene (about 40 to 35 million years ago) Hesperocyon was directly ancestral to all later canids — and thus to the genus Canis, which branched off from a subfamily of canids about six million years ago.
Was this 18000 year old Siberian puppy a dog or a wolf?
Meet Dogor, an 18,000-year-old pup unearthed in Siberian permafrost whose name means “friend” in the Yakut language. The remains of the prehistoric pup are puzzling researchers because genetic testing shows it’s not a wolf or a dog, meaning it could be an elusive ancestor of both.

Is Epicyon a wolf?
Possibly the largest prehistoric dog that ever lived, Epicyon was a true “canid,” belonging to the same general family as wolves, hyenas and modern dogs—and was thus a different beast altogether from the non-canid “creodont” mammals (typified by the giant Sarkastodon) that ruled the North American plains for millions …
