Megantereon

Megantereon was an ancient machairodontine saber-toothed cat that lived in North America, Eurasia, and Africa. It may be the ancestor of Smilodon. Megantereon was built like a large modern jaguar but somewhat heavier. It had stocky forelimbs with the lower half of these forelimbs lion-sized. It had large neck muscles designed to deliver a powerful shearing bite. he smallest species from Africa and the lower Pleistocene of Europe have been estimated to only 60–70 kilograms. However, these estimations were obtained from comparisons of the carnassial teeth. Younger estimations, which are based on the postcranial skeleton, lead to body weights of about 100 kilograms for the smaller specimens. In agreement with that, more recent sources estimated Megantereon from the European lower Pleistocene at 100–120 kilograms.
