<P> In North America , Smilodon hunted large herbivores such as bison and camels , and it remained successful even when encountering new prey species in South America . Smilodon is thought to have killed its prey by holding it still with its forelimbs and biting it , but it is unclear in what manner the bite itself was delivered . Scientists debate whether Smilodon had a social or a solitary lifestyle ; analysis of modern predator behavior as well as of Smilodon 's fossil remains could be construed to lend support to either view . Smilodon probably lived in closed habitats such as forests and bush , which would have provided cover for ambushing prey . Smilodon died out at the same time that most North and South American megafauna disappeared , about 10,000 years ago . Its reliance on large animals has been proposed as the cause of its extinction , along with climate change and competition with other species , but the exact cause is unknown . </P>
