Uncovering Jurassic America's Carnivorous Secrets through Gnawed Dinosaur Bones

Tooth-marked bones of giant plant-eating dinosaurs in North America provide insight into the feeding habits of large carnivores during the Jurassic period. The study focused on bite marks made by non-Tyrannosaur carnivorous theropods on the bones of sauropod dinosaurs. The research revealed that bite traces were more abundant than previously realized and indicated that theropods likely fed on juvenile sauropods and scavenged larger carcasses. The findings shed light on the ecological relationships between dinosaurs in the Jurassic era.
