Study reveals sabre-toothed predators evolved varied tooth shapes for puncturing prey and resisting breakage.
Researchers found that sabre-toothed predators evolved their distinctive teeth multiple times due to their optimal balance between puncturing prey effectively and resisting breakage.
Extreme forms like Smilodon were highly efficient at puncturing but more prone to breaking, while less extreme forms like Dinofelis offered a more balanced trade-off.
The study, published in Current Biology, challenges the traditional classification of sabre-toothed predators and reveals a spectrum of sabre-tooth shapes, suggesting diverse hunting strategies.
