Homotherium is an extinct genus of machairodontine saber-toothed predator, often termed scimitar-toothed cats, that inhabited North America, South America, Eurasia, and Africa during the Pliocene and Pleistocene epochs, existing for approximately 4 million years. It became extinct in Africa some 1.5 million years ago.
Thought to have been extinct for 10,000 years, there are still some that remain alive on Primeval Island. In fact, they are one of the island's apex predators. They are also one of the most common cats on the Island, alongside the Smilodon, Cave Lion, American Lion, American Cheetah, Dinofelis, and Ngandong Tiger.
