Diet , Habitat , Lifestyle


Preferred large thick skinned herbivores as their source of food like mastadons (mammoths, bison, horses)


The sabre-toothed cat lived in shrubby areas grasslands and pine forests that supported the prey of the cat. Smilodon fatalis and Smilodon populator lived in the americas until the end of the ice age.


  • Due to their short, heavy musculature limbs they were thought to be ambush predators (not built for speed)
  • Used large saber tooth canines to pierce through the throat of their prey
  • Hunted large herbivores so some thought they were pack hunters


factors that caused extinction

climate change

humans hunting the cat

change in vegetation,

decline in food sources

extinction proves that evolution is not always progress
