Fossilized dinosaur brain unearthed

摘要

Dinosaur smarts may be a mystery, but their brains, at least, are now more concrete. A chunk of petrified brain tissue discovered in a tidal pool in southern England is the first reported from a dinosaur, researchers claim. The roughly 133-million-year-old fossil preserves the brain's wrinkled topology, said paleontologist David Norman of the University of Cambridge, who described the find October 27.
