Physical Description
Physically, the cats stood about as tall as a modern lion (around 2 m in length), with a highly muscular body, around 180-230 kg in mass. Interestingly, before their discovery, all known saber-toothed cats fell into two general categories. Dirk toothed cats had long upper canines and stout legs. Scimitar toothed cats had only mildly elongated canines, and long legs. Xenosmilus broke these groupings by possessing both stout muscular legs and body, and short broad upper canines.
