Description
Edmontosaurus was a large duck-billed dinosaur with a broad beak, powerful hind legs and hundreds of replacement grinding teeth. Some fossils preserve skin impressions and soft crest structures, showing that the body had more ornamentation than bones alone suggest. It could probably walk on two or four legs and fed on plants at different heights. Fossil finds do not establish the size of its herds.
Habitat
Coastal plains, rivers and marshy lowlands.
