And in Eurasia and America in the era of ice were carried huge cat, called cave lions. Distributed they were on the vast territory from the British Isles and the Caucasus to the New Siberian Islands, Chukotka and Primorye in the Old World, and from Alaska to Mexico - in the New. Naturally, the settlement of cave lions passed through Beringia, although it is not known where it was their homeland - in Eurasia or America. Other representatives of the extinct felines were machairodus - saber-toothed cats. They are sometimes called the saber-toothed tigers, but the proportions of the body in machairodus were quite different than those of the tigers: the front legs are much longer and heavier, rear, on the contrary, shorter and weaker than the tiger. Machairodus could not make so light and powerful jumps, as does a tiger or a lion. But compensation had terrible teeth of this predator, bent like a Turkish yataghans and reaching lengths of a quarter of a meter, and powerful talons. Saber-toothed predators spread on all continents except Australia. A dozen of their birth found in Eurasia in layers starting from the middle of the Tertiary period and up to the period of the great glaciations. Although machairodus no serious competitors, they all died during the Quaternary period. Extinct and the other members of the cat, once common in the Old and the New World: "lozhnosablezubye", "eusmilusy" and others. All cats in different periods of moving between the Old and New Worlds for Bering bridge sushi. And as vegetarians or machairodus or cave lions, jaguars or ancient, nor any other feline predators were not, then they obviously needed a production - herbivores.
