Maiasaura Dinosaur Fossils
At up to nine meters long Maiasaura was not amongst the largest known hadrosaurid dinosaurs, though it still tipped the scale to be considered big for its kind. Like with its hadrosaurid relatives, Maiasaura is thought to have been a primarily bipedal dinosaur, though one that was at least capable of balancing if not walking upon just its hind legs. The exact posture assumed was probably more dependent upon what the Maiasaura in question was actually doing at the time. Maiasaura had a low crest on top of its snout and because it is solid, this indicates that Maiasaura was one of the saurolophine hadrosaurs.
