On Wednesday, November 4, the Marion Natural History Museum's afterschool group learned how fossils form and the differences between body, mold, cast, and trace fossils. Many thanks to Luke Douglas, anthropologist and teacher, who shared his presentation on fossil formation. We then had fun looking for examples of these fossil types in the museum's collection. Thanks go to Jim Pierson, a fossil enthusiast, who helped us create our own "dinosaur fossils" to take home. Photo courtesy of Elizabeth Leidhold
