This duck-billed dinosaur arm bone tells a real prehistoric story. The deep bite marks match the teeth and power of Tyrannosaurus rex, showing the arm was likely in a T. rex’s mouth during a hunt or feeding. Fossils like this give rare, direct evidence of predator-prey interactions from about 66 million years ago, freezing a moment of violence in stone.
