Dire wolf

The dire wolf (Canis Dirus) is a prehistoric canid in the genus Canis, roughly the same size as the gray wolf but the dire wolf was heavier. The dire wolf was the largest canine species ever. They were known to attack bison, horses, and other animals. They were also known to compete with bears, saber-toothed cats, American lions, and other predators. Its 1st remains were found in 1854 in La Brea and nearly 4,000 wolves were found in La Brea. The dire wolf lived in both North and South America. The dire wolf was possibly South America's only Canis species.
