Pliosaur

Bite marks

The holes in this plesiosaur limb bone were probably made by another large marine reptile that may have hunted it or scavenged its body. It’s thought that predators such as the pliosaur delivered a crippling bite to their prey and then waited for them to weaken through blood loss before going in for the kill. This would be to avoid injury to itself – even the great white shark today uses the same ploy. One really convincing piece of evidence for such an interpretation is that bite marks are more common on limb bones than any other bones in the plesiosaur body, suggesting that the limbs were targeted with disabling bites.
