Story summary
- Charlie Roger Scherer of University College London led a study linking tiny dinosaur forelimbs to large skulls.
- Reduced forelimb length correlated with skull durability rather than body size across five lineages, showing short arms evolved as heads grew larger.
- Andre Rowe of the University of Bristol said vestigial arms may still function, noting the authors will study forelimb reduction’s effect on feather evolution and flight.
