Saber-toothed predators — such as the famous saber-toothed cat Smilodon fatalis — evolved multiple times across different mammal groups. Their unusual teeth were functionally optimal and highly effective at puncturing prey, according to new research led by University of Bristol paleontologists. Graphic showing functional optimality drives repeated evolution of extreme saber-tooth forms. Image credit: Tahlia Pollock. “Our study helps...
