1.05" Hadrosaur Tooth (Lambeosaurus?) - Two Medicine Formation

This is a very large, 1.05" Hadrosaur from the Two Medicine Formation of Montana. Given that most of the tip has been worn down, this tooth would have been absolutely gigantic for a Hadrosaur tooth.

There are several large hadrosaurs known from this formation including Lambeosaurus, Brachylophosaurus and Kritosaurus which it could possibly be. The collector labeled it as being Lambeosaurus, but identifying an individual tooth even to the genus level is partially guesswork.
