Uncovering Dinosaur Predation through Bone Bite Marks

Paleontologists studying bite marks on sauropod bones have concluded that the marks were likely made by scavenging meat-eating dinosaurs rather than predators that actively hunted and killed adult sauropods. The researchers found that the bite marks were more likely to be on the bones of old, sick, injured, or otherwise vulnerable sauropods. The study suggests that it would have been too risky for predators to try to bring down an adult sauropod, which could weigh up to 50 tons. Instead, the large theropods likely targeted and consumed young sauropods, which were more defenseless.
