    Synthetoceras is the first in our weekly series of "Extinct Mammals with the Craziest Headgear." It roamed the American plains several million years ago. Special thanks to illustrator Lucas Lima for creating the images in this series.

    A true single-toed horse, Pliohippus roamed the grassy plains of North America about 12 million years ago, and may have survived into the Pliocene epoch. Although it closely resembled modern horses, there's some debate about whether the depressions in its skull, in front of its eyes, are evidence of a parallel branch in equine evolution.

    Giant Short Faced Bear-Was the largest bear ever known but also the largest carnivorous land mammal ever to exist. It lived from 800,000 to 12,500 years ago, during the ice age. It had the capability of catching and killing bison, elk and other large animals. However, it was probably more of a scavenger. Because of it's size, it could easily chase other predators off their kills.Dietary/Omnivore Family/Ursidae Origin/USA
