One piece Cast replica measures: ___

Mary Ann Hadrosaur was found in the Hell Creek Formation of Montana by the Naranjo expedition in 2008. She lived in a swampy environment. Hadrosaurs were known as duck-billed dinosaurs and were herbivores. Mary Ann is very well preserved. If you look down her back you can see tendons that were fossilized along with some impressions of her skin. Her foot is a very detailed and a great example of her skin impressions. From her we can tell what the skin and tendons of a hadrosaur probably looked like. She is the first Hadrosaur found with her hooves. Mary Ann Hadrosaur is 26 ft. long.

The reason we know that Mary Ann lived in a swampy environment is because of the fossils that we found near her. Fossilized pine cones were found near her. Leaves, fly larva, and petrified wood all gave us clues as to what environment she lived in. There is also a piece of chewed wood that she could have been possibly chewing before her death. All of these things help us to know the environment that she was in when she died.
