Duck-billed dino could slice and dice.

During the late Cretaceous period, duck-billed dinosaurs were the Cuisinarts of that period.Horses, elephants and other modern grazers resemble the surface of the teeth on the duck-billed dino. Six distinct types of tissue wore to differing degrees resulting in creating distinctive peaks and valleys in the animals teeth. Varying hardness of the tissues allowed different dental features to form as a tooth wore down demonstrated by computer simulations. Unlike mammals duck-billed dinosaurs continuously shed and grow teeth. Teeth form and functions of teeth changed over an animals lifetime says new research.
