In a recent research, scientists analyzed the remains of the saber-tooth cats and American loins and were unable to find any good reason behind their extinction.

The scientists involved in the research said that these species had enough to eat all the times and even when they got extinct, there was no shortage of food for them. They were known to feed upon animal carcasses most of the times.

These species got extinct around 12,000 years ago but the researchers have not been able to recognize reasons behind their extinction. After analyzing their teeth they found that they fed upon good amount of diet even during the days they got disappeared. They looked into teeth of the cats from 30,000 years ago to latest samples from 12,000 years ago.

After the intensive research into their fossils, they denied the fact that lack of food was cause of their extinction. "Tooth wear patterns suggest that these cats were not desperately consuming entire carcasses and instead seemed to be living the 'good life' at least up until the very end", said Larisa DeSantis, head of the research team and a paleontologist at Vanderbilt University.

There are many other theories suggesting the cause behind extinction such as climate change, human activities, hunting etc but none of them is verified as of now.
