Saber Toothed Cats Didn't Starve Into Extinction

The fearsome felines of the Ice Age in California don't show signs of starving immediately before their extinction. Teeth of saber-toothed cats and the American lions didn't have wear marks that would have suggested the cats were gnawing on bones in hunger near the time of the cats' extinctions.

"Tooth wear patterns suggest that these cats were not desperately consuming entire carcasses, as was expected, and instead seemed to be living the 'good life' during the late Pleistocene, at least up until the very end," said lead author Larisa DeSantis of Vanderbilt University in a press release.

Tooth wear patterns did reveal previously unknown differences in the two cat species behavior. Saber-toothed cats, also known as Smilodon, appeared to have regularly crunched bones, and showed no increase in this dietary distinction toward the end of their reign, which spanned from 30,000 to 10,000 years ago. American lions however, were more finicky and seem to have avoided bones, much as modern cheetahs do.

The extinction of the predators remains a mystery. Some have suggested that the changing climate at the end of the last Ice Age along with an influx of animals from Asia, including the ferocious Homo sapiens, may have left Smilodon with nothing to grin about.
