When did the saber-toothed tiger go instinct?

Saber-toothed tiger, also called Smilodon, is an extinct genus of machairodontine saber-toothed cats that inhabited the American during the Pleistocene epoch (2.5 million to 10,000 years ago). The last species of saber-toothed tiger, Smilodon populator, became extinct around 11,000 years ago during the Late Quaternary extinction event.
