Where found: The Americas
Sivatherium is a genus of extinct animals in the giraffe family Giraffidae. It was found in both Africa and Asia and appeared several millions of years before the beginning of the stone age. It is thought to have become extinct around 800,000 years ago.
Sivatherium resembled a modern okapi, but was significantly larger. It had two pairs of horn-like growths known as ossicones on its head. One pair was large and resembled antlers.
