The saber-tooth tiger's real name is Smilodon – it was not actually a tiger!

Its massive canine teeth could grow up to 28 cm (11 inches) long

Smilodon lived during the Ice Age, between 2.5 million and 10,000 years ago

It weighed up to 400 kg – heavier than today's lions and tigers

Despite its name, it was more closely related to modern cats than to tigers

Smilodon likely hunted large prey like mammoths, bison and giant sloths

Fossils have been found in both North and South America

It probably lived and hunted in groups, like modern lions

Its legs were short and powerful, built for ambush rather than long chases

Smilodon went extinct around 10,000 years ago, likely due to climate change and loss of prey
