This is a the end of a Hadrosaur tibia from the 70 million year old Two Medicine Formation (Judith River Group) of Montana. The most likely genus would be Lambeosaurus. The tibia section of 5.5" in length and about 4" wide.

What is so interesting about this bone is that it has deep BITE MARKS on one side of it, probably made by a Tyrannosaur (Albertosaurus, Daspletosaurus, etc).
