21mm hadrosaur crown

This hadrosaur crown—the chewing surface of a tooth from a duck-billed dinosaur—is a fascinating piece of Cretaceous history. Hadrosaurs had complex dental batteries made up of hundreds of tightly packed teeth, perfect for grinding tough plant material. This single crown shows the distinct ridges and wear patterns from a lifetime of feeding. Tough, efficient, and built for bulk grazing, it’s a small but powerful trace of one of the most successful herbivores of the dinosaur age.
