1.61" Hadrosaur Vertebra - Two Medicine Formation
This is a Hadrosaur caudal (tail) vertebra from the Two Medicine Formation (Judith River Group) of Eastern Montana. There are several known Hadrosaurs from this formation including Brachylophosaurus, Kritosaurus and Lambeosaurus, but you couldn't accurately assign an isolated vert like this to a specific genus. There is only minor weathering or erosion to this vert and no restoration or repair.
