Description
Maiasaura was a large hadrosaur (duck-billed dinosaur). Its name means 'good mother lizard' in reference to the first finds of nests and young. It was the first dinosaur in space when Loren Acton took fossils on a Spacelab mission in 1985. Their distinctive crest was likely used in head-butting contests. They could walk on four or two legs, and they most likely lived in vast herds.
Discovery
The first find for Maiasaura was a skull in 1979. Since then other finds have been uncovered around Montana. These finds also provided the first proof that large dinosaurs raised and fed their young.
Paleoecology
The Two Medicine Formation was a semi-arid region with conifers, ferns and horsetail plants.
