Summary:
- Researchers have discovered preserved blood vessels inside the fossilized bones of the world's largest Tyrannosaurus rex specimen, named "Sue."
- This remarkable finding provides new insights into the biology and physiology of these ancient, fearsome predators, as well as the potential for further discoveries of soft tissue preservation in dinosaur fossils.
- The discovery of these well-preserved blood vessels challenges the traditional view that soft tissues cannot be preserved over millions of years, opening up new avenues of research into the evolution and anatomy of dinosaurs.
