Smilodon is an extinct genus of saber-toothed cats that lived during the Pleistocene epoch in North and South America. It is one of the most famous prehistoric species, and its name means "knife tooth" in Greek. Smilodon had long, sharp canine teeth that were used to hunt large prey such as bison, horses, and camels. Its powerful jaws could crush bones and its body was built for strength and agility. Smilodon went extinct around 10,000 years ago, likely due to a combination of climate change and competition with humans for food sources.
