2.87" Hadrosaurid Cervical or Dorsal Vertebrae

This is a cervical or dorsal vertebrae (neck and back) from a Hadrosaurid found in the Two Medicine Formation (Judith River Group) of Eastern Montana. The bone is 2.87" wide and nicely preserved with some surface weathering, but most of the shiny outer bone surface remains. The processes themselves have eroded away completely, hus making it hard to determine the exact positioning of this vertebrae. There is no restoration.

Within the Judith River Group there are 3 major hadrosaurids, Brachylophosaurus, Kritosaurus, and Lambeosaurus with Brachylophosaurus being the most commonly found. With just a single bone it is hard to differentiate between the different genera and give a definitive identification.
