The extinction of Saber-toothed cats is still a mystery

So, the saber-toothed cats went extinct about 12,000 years ago at the end of the late Pleistocene.

Eh…Pleistocene?

Well, the Pleistocene epoch is the geological epoch which lasted from 2.6 million to 11,700 years ago blah blah blah…..Just think of it as the period when the large mammals like mammoths and saber-toothed cats were ruling the land.

And how did the saber-toothed cats go extinct?

Because they all died near the end of the last Ice age, scientists thought that they might have run out of food due to the climate change. Starvation would have been the most plausible cause for their extinction.

It seems very reasonable doesn’t it ?

Wait just a second……

Researcher Larisa DeSantis said that the big cats tend to spent more time chewing the bones of their prey when there is a lack of food and we would be able to see the wear mark on their teeth.

And guess what? The saber-toothed cats did not have wear patterns on their teeth, according to the recent fossil analysis.

So no one really knows what caused the extinction of the giant cats.

What we do know is that human species started spreading around the world at that time.

Giant cats disappeared when humans appeared. Ummm…
