On the perilous Jurassic Period landscape of western North America, it was good to be big. Your life may have depended upon it.
Palaeontologists have conducted a study scrutinising bite marks left by meat-eating dinosaurs on the bones of sauropods - the familiar plant-eating dinosaurs with long necks, long tails and four pillar-like legs that were the largest land animals around - about 150 million years ago. The examination offered insight into predator-prey dynamics during the dinosaur age.
Of about 600 bones checked, bite marks - often deep grooves left in stout bone - were detected on 68 of them, spanning 40 individual sauropods and representing at least nine species.
