Amphimachairodus is a large machairodontine (saber-toothed) cat that lived in Miocene China around 8 million years ago. It is a fast runner, with a moderately-long tail that allows it to make quick turns in active pursuit, though it cannot sprint for very long. They can weigh up to 1080 pounds and are almost 4 1/2 feet at the shoulder. Their favorite prey is the tusked rhinoceros, Chilotherium, which they kill by pinning down and severing their throats with their saber teeth.
