With its impressive canine teeth measuring up to 20 cm, the smilodon holds the position of the most powerful feline that has ever existed. It is also known as the ''sabre-toothed tiger''. This predator appeared about 2.5 million years ago in the Americas and must have lived in a clan and hunted in the same way as modern lions. Smilodons could attack large animals such as bison or young mammoths, which they had to hunt in groups. The last smilodons became extinct 10,000 years ago.Dinosaurs - With the dinosaurs, tread the Jurassic earth, meet the legendary T-Rex, walk through vast plains with the velociraptor or fly with a pteranodon.
