Maiasaura, a duck billed dinosaur, found in large bone beds, must have traveled in herds of thousands of individuals. Evidence from nesting sites, indicate parental care which earned Maiasaura its name, and reputation, as “good mother lizard.” This herbivorous dinosaur had a relatively flat skull and a small crest above the eyes. Like many hadrosaurs Maiasaura’s only real defense from predators would have been the safety of the herd and speed, provided by very powerful hind legs.
