A new study that examined bite marks on the bones of long-necked sauropod dinosaurs, like those found in Wyoming, reveals they were like a 1980s heavy metal band -- they lived fast, they died fast, and they had a lot of sex.
On the perilous Jurassic Period landscape of western North America, it was good to be big. Paleontologists have conducted a study scrutinizing 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. 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.
Dinosaur fossils with bite marks have shed new light on the interactions between Jurassic predators and some of the largest creatures ever to roam the Earth.
