These extinct animals were known for their terrifying, blade-like canine teeth in the upper jaw that protruded from their jaws when closed. If you ever picture the Ice Age, then these animals are probably the ones that come to mind. These meat eaters are ferocious and vicious, and aren’t the type of cat you’d want to come face to face with. They existed from the Eocene through to the Pleistocene Epoch, which was around 56 million to 11,700 years ago. They also belonged to the Nimravidae family, which became extinct around 37 million to 7 million years ago (Britannica).
