Dinosaur Discoveries

Herbivores Were Great Chewers

Researchers are now discovering that giant plant-eaters, such as Hadrosaurids or a Corythosaurus, may have had teeth with grinding surfaces much like a modern day horse or bison. Their teeth were complex, combining up to six types of tissue, and all varying in hardness. Scientists speculate that this is due to their diets, including tough, tooth-gouging particles from plants.

Researchers believe the complex nature of the herbivores teeth is reason that they were so common.

For more on this discovery, visit NBC News.
