Up until about 10,000 years ago, the saber-toothed cat Smilodon was a ferocious predator that dominated the primeval landscape of the Americas. Smilodon means "knife-tooth", a perfectly fitting name given its enormous fangs, which measured up to 28 centimeters in length. This 250-kilogram feline was an apex predator and primarily hunted the large mammals it shared the land with, such as bison and camels.
