Edmontosaurus was a large, plant-eating, 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.
Discovery of fossils [change]
Edmontosaurus was named by Lawrence M. Lambe in 1917 from a fossil found in Edmonton Rock Formation, 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.
