Research overview: Homotherium, the cosmopolitan scimitar-toothed cat

This overview surveys Homotherium, the scimitar-toothed sabercat whose fossils span North America, Eurasia, and Africa, making it one of the most widely distributed of all machairodonts. Distinguished by shorter, coarsely serrated upper canines and long forelimbs paired with shorter hindlimbs, it had a sloping, hyena-like profile suited to open-country hunting. The survey reviews the genus's broad geographic and temporal range, debates over how many species it contained, and how its anatomy contrasts with the dirk-toothed Smilodon. It also covers Homotherium's apparent preference for open habitats and large prey, its cursorial adaptations, and how its near-global occurrence makes it a key taxon for understanding sabertooth biogeography and the repeated success of the sabertooth body plan.
