About
Edmontosaurus
Named Edmontosaurus in 1917 by Lawrence Lambe, fossils of Edmontosaurus have since been found in many parts of Western North America. These fossils suggest that Edmontosaurus probably migrated with the seasons.
A number of unique fossils of Edmontosaurus have been found, including a partially mummified fossil with food contents in the gut region, and skin impressions.
Edmontosaurus was a large hadrosaur, or duckbilled dinosaur. Like most other hadrosaurs, this animal had a toothless beak, with teeth further back in the cheeks. These teeth were arranged in a manner that allowed them to remain sharp by sliding back and forth against each other.
The skull shows signs that Edmontosaurus may have had large inflatable flaps of skin near its nose, perhaps used to attract a mate, or to make a loud honking noise.
