Smilodon populator ("the Smilodon that brings devastation") was a machairodontine saber-toothed cat species. Smilodon populator first appeared in South America about 1 million years ago and became extinct about 10,000 years ago. It was much larger than its cousins, Smilodon fatalis and Smilodon gracilis, possessing a massive chest and front legs. Standing at 120 cm at the shoulder, it was the size of a large lion. The weight range has been estimated at somewhere between 200 and 300 kg (400 and 600 lbs). It had sabers which could be 7 to 8" long and were used for making the cat's prey bleed to death while being held down by powerful forelimbs. These large canines were flat and wide with serrated edges. The conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future. ...

It is strongly suspected that S. populator outcompeted the indigenous saber-toothed marsupial, Thylacosmilus, which also lived in South America. The competition for prey (such as the Toxodon and Macrauchenia), led them into rivalry and eventually led to the extinction of the marsupial sabre-tooth. This article is about mammals. ...

It is unknown what caused the abrupt extinction of Smilodon. Theories include climate change at the end of the last ice age causing an adverse change in vegetation and prey, and human encroachment. Variations in CO2, temperature and dust from the Vostok ice core over the last 400 000 years For the animated movie, see Ice Age (movie). ...
