Abstract in brief
The study examines how the shape and strength of the jaw (mandible) in Smilodon fatalis (saber-toothed cat) change during its growth, using detailed 3D analysis of fossil skulls.
It finds that Smilodon likely had a prolonged weaning period and a different growth pattern compared to lions, with significant jaw shape changes occurring later in development.
Despite being more efficient at biting later in life, Smilodon’s jaw development suggests it required extended parental care, which might have influenced its overall growth and hunting abilities.
