Edmontosaurus Duck-Bill Dinosaur Tooth from Hell Creek

Description: Edmontosaurus is a genus of crestless duck-billed dinosaur. Edmontosaurus was one of the largest hadrosaurids, measuring up to 13 meters (43 ft) long and weighing around 4.0 metric tons (4.4 tons). It is known from several well-preserved specimens that include not only bones, but in some cases extensive skin impressions and possible gut contents. It was an herbivore that could move on both two legs and four. Edmontosaurus is thought to have lived in groups, and may have been migratory as well. It is well represented in the fossil record.
