I'm going to be doing a series on the evolution of felines. I'm going to pick several prehistoric cats throughout history and do anatomy studies on them, and see how cats have changed over time. This isn't going to be linear with a single cat, it'll just be cats I select at different time periods. So starting things off is machairodus aphanistus, which lived around late miocene to middle pleistocene. These cats had narrow heads and short legs, therefor they were probably ambush predators. I hope you guys enjoy my next big project!
