Edmontosaurus
genus of reptiles (fossil) / From Wikipedia, the free encyclopedia
Edmontosaurus is a basal duck-billed dinosaur from the latest Cretaceous stage. It had short arms, a long, pointed tail, three-toed, hoofed feet, and mitten-like hands. Its head was flat and sloping with a wide, toothless beak, cheek pouches, and hundreds of closely-packed cheek teeth that ground up its food. It is the same animal as Anatotitan. There are two species, and the animal has been called by several other names in the past.

Edmontosaurus was named from a fossil found in the Horseshoe Canyon Formation,[1] in Alberta, Canada. Many Edmontosaurus fossils have been found, in Alberta, and Alaska, Wyoming, Montana and New Jersey in the USA. Two mummified Edmontosaurus fossils were found in Wyoming.
The distribution of its fossils suggests that it preferred coasts and coastal plains. It could move on two legs and on four. Because it is known from several bone beds, Edmontosaurus is thought to have lived in groups. It may have been migratory.
