2.3" Fossil Dinosaur Bone Section - Wyoming
This is a 2.3" wide section of dinosaur bone from the Lance (Creek) Formation in Wyoming. Based on abundance and the location of collection, it's very likely that this came from the famous hadrosaur, Edmontosaurus annectens. That being said, with such little bone present, it's difficult to provide an accurate bone identification.
