14 DAY TRIAL // Two dinosaur species named Diplodocus and Camarasaurus used to feast on so many plants that they had to change their teeth just weeks after growing them.
Diplodocus got a new chomper once every 35 days. Camarasaurus, on the other hand, was more resilient, and only had to grow a new tooth once every 62 days or so.
Paleontologists explain that the dinos' new teeth were carefully tucked away inside their jaws. Whenever an old tooth stopped being of any use, they stepped up and took its place.
Diplodocus carried five baby teeth at a time inside each tooth socket, while Camarasaurus only packed three, sources say.
“Effectively, sauropods [dinosaurs such as Diplodocus and Camarasaurus] took a 'quantity over quality' approach to making teeth, opposite the approach taken by large animals – mammals – today,” Dr. Michael D'Emic explains.
