Smilodon fatalis had a robust build and powerful jaws. Its most distinctive feature was its long, saber-like upper canine teeth, which could grow up to 12 inches (30 cm) in length. These teeth were used for slashing and stabbing prey. Smilodon fatalis also had shorter, serrated teeth in its lower jaw that were used for cutting meat.
Smilodon fatalis was a social animal and lived in groups of up to 30 individuals. These groups were led by a dominant male, who was responsible for protecting the group and defending its territory. Smilodon fatalis was also a skilled hunter and was able to take down large prey. It would typically stalk its prey and then ambush it, using its long canine teeth to deliver a fatal blow.
Smilodon fatalis eventually became extinct, likely due to a combination of factors, including climate change and competition from other predators. However, it remains one of the most iconic prehistoric animals and is a symbol of power and strength.
