Augustynolophus morrisi was a hadrosaur (duck-billed dinosaur) that lived around California in the Late Cretaceous period (anywhere from 100 to 66 million years ago). There are only two known fossil specimens of the species (both were found in California).
This prehistoric herbivorous reptile was one of the few species of dinosaur to chew its food. Augustynolophus stood at about 10 feet tall and was 30 feet long from its head to the tip of its tail.
