- A new study suggests that the tiny arms of large meat-eating dinosaurs, such as Tyrannosaurus rex, are linked to the development of their powerful heads and jaws.
- 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.
