About Maiasaura

Around 75 million years ago, in a part of the Earth that is now Montana, a group of possibly hundreds of Maiasaura dinosaurs were quietly attending their nests. It is believed that these dinosaurs stayed together in nesting herds, much as modern birds often do today. As the dinosaurs played, cared for their young, and watched for danger, an unexpected natural disaster caused the entire heard to be buried in volcanic ash. This event helped to fossilize many different aged dinosaurs, including adults, young, and even unhatched eggs. X-rays show that the eggs actually contain fossilized embryos that were in the process of developing. Maiasaura had a long narrow snout very similiar to that of modern day horses. Above each eye was a small crest-like horn. Maiasaura was a hadrosaur, or duckbill, but lacked the head crest common on so many other duckbills.
