Smilodon fatalis was the North American saber-tooth, smilodon populator was the larger South American saber-tooth. In North America, their contemporaries included the giant short faced bear, the American lion, the dire wolf, the grey wolf, the brown bear, and eventually the Clovis peoples. All of these animals would have been in contention with one another for Natural Resources such as hunting grounds, food and water.

Under the right conditions any of these beasties would have been able to kill or be killed by one another. Fossil evidence indicates the the saber tooth was a social animal and may have lived in prides like lions which would have increased their ability to survive.

In the end, a radically changing environment leading to a mass extinction of prey animals, competition with other predators for dwindling resources and the introduction of the Clovis peoples to the America lead to the demise and final extinction of the saber tooth cats and their lineage about 10,000 years ago.
