Uncovering Dinosaur Predation through Bone Bite Marks

Paleontologists studying bite marks on sauropod bones from the Jurassic Period 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 deep grooves on 68 out of 600 bones examined, suggesting that the scavengers came across the bodies of sauropods that had already died from causes like old age or infirmity. The study also revealed that adult sauropods were likely not targeted by predators due to their massive size and the potential risk involved in attacking them. Instead, predators may have focused on young sauropods, which were more vulnerable.
