Smilodon fatalis
The Saber-Toothed Predator of the Pleistocene, Smilodon fatalis was one of the most formidable carnivores of Ice Age North America. With its iconic saber-like canine teeth and muscular frame, this apex predator dominated open woodlands and plains, preying on large herbivores such as bison and camels.
Description
Smilodon fatalis — Belonging to the class Mammalia, order Carnivora, family Felidae, Smilodon fatalis was a robust saber-toothed cat distinct from modern big cats. Adults weighed between 160–280 kg, with shoulder height around 1.1 meters and a body length of approximately 1.6–2.2 meters. Its massive forelimbs and short, powerful build were adapted for grappling large prey, while its elongated upper canines—up to 18 centimeters long—were used for precise killing bites. Unlike today’s cats, Smilodon likely ambushed prey rather than chasing it over long distances.

Hunt History
Early humans in the Americas may have occasionally clashed with Smilodon fatalis, though direct evidence of hunting is rare. More often, humans competed with it for the same prey. However, the advent of coordinated group hunting and the use of spears and atlatls may have allowed humans to drive Smilodon from carcasses or even kill them when threatened. The disappearance of large herbivores toward the end of the Ice Age, driven partly by human activity, likely sealed the cat’s fate.
Three archaeological and historical examples:
Rancho La Brea Tar Pits, California (c. 13,000 BCE) — Hundreds of Smilodon fatalis fossils trapped in asphaltic deposits, suggesting ambushes gone wrong at ancient kill sites.
Natural Trap Cave, Wyoming (c. 14,000 BCE) — Remains of Smilodon found with Ice Age bison and horse bones, indicating shared hunting grounds.
Panthera Cave, Argentina (c. 12,000 BCE) — Associated stone tools and large mammal remains hint that humans scavenged or hunted prey also targeted by Smilodon.
