Edmontosaurus aff. Regalis. Tooth (North America) Cretaceous.

Edmontosaurus included some of the largest hadrosaurid species, measuring up to 12 metres (39 ft) long and weighing around 4.0 metric tons (4.4 short tons). Evidence does exist in the form of two fossilized specimens housed at the Museum of the Rockies for an even greater maximum size of 15 m (49 ft) and weighing 9.07 metric tons (10.00 short tons) for Edmontosaurus annectens. Several well-preserved specimens are known that include not only bones, but in some cases extensive skin impressions and possible gut contents. It is classified as a genus of saurolophine (or hadrosaurine) hadrosaurid, a member of the group of hadrosaurids which lacked large, hollow crests, instead having smaller solid crests or fleshy combs. Edmontosaurus was one of the last dinosaurs to have lived, during the late Cretaceous 73-66 million years ago, alongside other dinosaurs such as Tyrannosaurs and Triceratops.The teeth from Edmontosaurus are not very common, this is well preserved tooth that has had to have a small repair, this does not detract from the look and is a nice example.
