Smilodon populator, often known as the saber-toothed tiger, was a large prehistoric feline native to the grassy plains and forested regions of South America. Notable for its elongated, saber-like canine teeth, it was a formidable predator that hunted large herbivores. This species thrived during the Pleistocene epoch.

Smilodon populator, commonly known as the South American saber-toothed cat, was native to South America. Its geographical distribution primarily included regions such as present-day Argentina, Brazil, and Uruguay, extending to the Andes and parts of the Pampas.

Smilodon populator inhabited a variety of environments across South America, from open grasslands and savannas to forests and scrublands. During the Pleistocene epoch, these regions experienced diverse climates ranging from temperate to semi-arid conditions.

As a top predator, Smilodon populator occupied the ecological niche of a carnivore, preying on large herbivores. Its adaptations for hunting included robust forelimbs and elongated canine teeth, which were suited for ambushing and subduing large prey. This species likely played a crucial role in controlling herbivore populations and maintaining ecological balance in its native habitats.
