Giant herbivore sauropod dinosaurs regularly replaced dull teeth with reserves stored in each tooth socket, according to research by paleontologists at Carnegie Museum of Natural History. "Sauropods have very simple teeth, so people have often thought of those dinosaurs as very basic and not very interesting," said John Whitlock, the study's lead author. "But it turns out that those simple teeth are tied into this remarkable teeth replacement and adaptation."
