Sabre-toothed cat teeth. Close-up of the fossilised canine teeth of a sabre-toothed cat (Smilodon sp.). This powerful carnivore was around the size of a large modern tiger, and lived in North and South America during the Upper Pleistocene epoch (around one million to 11,000 years ago). The upper canine teeth seen here were long, sharp, and shaped like backwards-curving daggers. They also possessed serrated edges. The sabre-toothed cat captured large elephant-like animals, common in the Pleistocene. When these prey animals disappeared the sabre-toothed cat died out, as it could no longer sustain itself.
