Research overview: sabertooth versus conical-toothed killing strategies

This overview compares the killing strategies of sabertooth cats with those of conical-toothed felids such as modern lions and tigers. Living big cats typically use short, robust canines and a powerful bite to grip the throat or muzzle and suffocate prey, a method that tolerates struggling and bone contact. Sabertooths, by contrast, traded bite force for an enormous gape and long, blade-like canines, requiring them to immobilize prey first and deliver a swift, precise slicing bite to soft tissue. The survey reviews how biomechanical and anatomical studies quantify these contrasting approaches, what each implies about prey choice and hunting behaviour, and why two such different solutions to large-prey predation both succeeded. It frames the comparison as central to understanding why the sabertooth form repeatedly evolved and ultimately vanished.
