The saber-toothed tiger is a common name for extinct saber-toothed cats, especially *Smilodon*, a genus of large prehistoric carnivores. Despite the name, it was not a true tiger and was only distantly related to modern cats. It lived in North and South America and became extinct about 10,000 years ago.

Name and classification

The term "saber-toothed tiger" usually refers to *Smilodon*, one of the best-known extinct saber-toothed cats. It was not a true tiger and belonged to an extinct group of cats within Felidae.

Physical characteristics

Saber-toothed cats are named for their elongated, blade-like canine teeth. Sources describe *Smilodon* as a powerful carnivore with large upper canines adapted for subduing prey.

Range and habitat

*Smilodon* lived in North and South America during the Pleistocene. It is commonly associated with open grasslands and plains, and many fossils have been recovered from sites such as the La Brea Tar Pits.

Extinction

The genus disappeared about 10,000 years ago near the end of the last Ice Age. Suggested causes include climate change, prey decline, and hunting pressure from humans.

Key facts

  • The name "saber-toothed tiger" is a popular but inaccurate common name.
  • *Smilodon* was an extinct genus of saber-toothed cats, not a modern tiger.
  • Saber-toothed cats were carnivores with long, curved upper canine teeth used for hunting.
  • They lived in the Americas during the Pleistocene Epoch.
  • They became extinct in the late Pleistocene, around 10,000 years ago.
