Why Did Smilodon Go Extinct? Ice Age History, Size, and Hunting Facts
Smilodon, often called the sabre-toothed tiger, was one of the most famous prehistoric predators. It lived during the Ice Age and is known for its long, curved canine teeth that looked like sharp swords. Although it looked like a tiger, Smilodon was not a true tiger. Studying Smilodon facts helps us understand ancient ecosystems, predator behaviour, and why some powerful animals became extinct.

- Adult Stage: Fully grown adults became powerful top predators.
- Lifespan: Estimated around 20–25 years.
