A broken rib from the world’s largest T. rex hid a 66-million-year-old secret

Researchers have analyzed a damaged rib bone from Scotty, the largest known Tyrannosaurus rex specimen, to uncover previously unseen biological processes occurring during its lifetime. Utilizing advanced non-destructive imaging techniques including neutron and X-ray scans, the team successfully peered into the internal structure of the fossilized bone. The analysis revealed an intricate, fossilized network of blood vessels that had developed as part of the dinosaur's healing process after an injury. This discovery provides unprecedented insight into the physiological recovery capabilities and internal bone pathology of apex predators from the Late Cretaceous. By visualizing these delicate vascular structures without damaging the original specimen, the study demonstrates the power of modern imaging technology in reconstructing the health and life history of ancient organisms that lived millions of years ago.
