Holly Woodward in Maiasaura Bone Field (IMAGE) Montana State University Caption Holly Woodward points at a Maiasaura fossil. Decades of research on Montana's state fossil -- the 'good mother lizard' Maiasaura peeblesorum - has resulted in the most detailed life history of any dinosaur known and created a model to which all other dinosaurs can be compared, according to new research published today in the journal Paleobiology. The study was led by Woodward, who did the research as her doctoral thesis in paleontology at MSU. Credit Photo courtesy of Karen Chin.
