Overview

• Scientists used 3D scanners to analyze 99 mandibles and 91 skulls from various species and eras.
• Results show a continuum of cranial forms linking modern cats and saber-toothed counterparts.
• Saber-toothed species exhibited faster morphological evolution early in their history.
• Reduced craniomandibular integration in these species allowed for greater adaptability.
• Specialized niches made saber-toothed predators more vulnerable to extinction.
