Hadrosaurs lived during the late Cretaceous Period in areas with warm, wet climates. They had flat "duck bill" mouths that probably helped them chew tough plants, and large crests on the back of their heads. We found a piece of paper that showed that males had long crests and females had shorter, sharper curved crests, but Alan explained to us that that idea was wrong and they were completely different species that lived at different times!
Hadrosaurs were huge, from 10-40 feet long, and they had three toes on their feet. After a full day of digging, we found fossilized toe, it was awesome!
Overall, the field trip was a lot of fun, a lot of work, and I feel like I learned a lot from it. Paleontology takes a lot of patience, but finding bones after searching all day was really rewarding, and I wouldn't mind learning more.
