Maiasaura

Maiasaura’s name translates to ‘good mother lizard’, as it was the first dinosaur to show evidence of feeding hatchlings while they were still in the nest. Notable for having a bill rather than a snout or nose, Maiasaura was a large herbivore (growing up to 9m in length and weighing in excess of 900kg) that fed on leaves, branches, ferns and other plants.
