Researchers found that the head became the primary weapon for hunting, replacing the role of forelimbs in subduing prey. This evolutionary shift coincided with the increasing size of prey, including gigantic long-necked sauropod dinosaurs. The study quantified skull robustness, finding a strong correlation between reduced forelimb size and the strength of the skull, with T. rex scoring highest. Scientists concluded that the reduction in forelimb size was a result of their redundancy in prey capture, as powerful bites and robust skulls took over.
