Time
Cretaceous Late Campanian
Classification
Ornithischia Ornithopoda Hadrosauridae Hadrosaurinae Brachylophosaurini [Maiasaurini] [Brachylophosaurs]
Diet
Herbivore
Fossilsite
Upper Two Medicine Formation, Montana, US
Length
9 meter
Info
Genus - Typespecies - Skull - Eggs
Whits its broad, duck-lile beak, powerful jaws, and batteries of self-sharpening cheek teeth, Maiasaura (\\\\\\\\\\\\\\\"good mother lizard\\\\\\\\\\\\\\\") is a typical example of the \\\\\\\\\\\\\\\"duckbilled\\\\\\\\\\\\\\\" dinosaurs.
It is placed in the family Hadrosauridae on account of its lack of a hollow head crest, and in the subdivision known as the Maiasaurini [Brachylophosaurs] because of the solid, horn-ilke crest above its eyes and the triangular projections on its cheek bones.
Since 1978 thousands of specimens have been found including articulated skull and postcrania, embryo to adult. Maiasaura is disitinguished from the lambeosaurids by having only a small deltapectoral crest on the humerus (upper arm bone).
