Machairodus is a genus of large machairodontine saber-toothed cats that lived in Europe, Asia, Africa and North America from the late Miocene to the Middle Pleistocene. It is the animal from which the family Machairodontidae gets its name and has since become a wastebasket taxon over the years as many genera of sabertooth cat have been and are still occasionally lumped into it.
