These amber pieces come from the Horseshoe Canyon Formation and I believe specifically near the hadrosaur ilium that we found (hadrosaur ilium). They are the clearest pieces of amber found from the Horseshoe Canyon Formation yet!
7-MB-22 was our first dromaeosaur tooth ever found (and our only one found as of now). It was found on our second trip to the Tolman Bridge area in October of 2024. It was initially thought to be a shiny rock until it was picked up and examined more closely. Our best guesses to the species it belongs to is Atrociraptor marshalli or Albertavenator curriei as they were two dromaeosaurs that lived in the Horseshoe Canyon Formation.
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.
