Notes

This fossil rib of a plant-eater shows tooth marks from two different-sized predators. Specimens like this produce the only direct evidence as to which dinosaurs featured on predators' menus. You can also see a large bone growth on part of the rib. This may have been from a healed injury or a disease that affected the bone.
