Maiasaura is a hadrosaur from North America during the late-cretaceous period, around seventy-six-million-years ago.


Maiasaura got its name due to being discovered with eggs. They had a small, spiky crest in front of the eyes. This crest may have been used in headbutting contests between males during the breeding season.
