5-MB-17

5-MB-17 Is a vertebra likely from an Edmontosaurus regalis becuase of it's more elongated shape. Usually hadrosaur vertebrae are more hexagonal while Edmontosaurus had a shape more like the one in the cover image. 5-MB-17 was also one of the fossils found on our first fossiling trip and was initially thought to be from a theropod because at the time we only knew that theropod vertebrae were heart shaped but not how the shape actually looked in real life which was not what we found.
