Many of us collect Edmontosaurus sp. skull elements and bones. Attached find a very interesting paper that describes skull elements on an Edmontosaurus regalis which is the Hadrosaur species found in the early Maastrichtian of Alberta. It's a very close cousin to the late Maastrichtian Edmontosaurus annectens found in the Hell Creek/Lance Formations.
