They lived at the time of the K-T extinction, during the Cretaceous time period of the Mesozoic. This was about 65 million years ago.

Early depictions showed hadrosaurs swimming in swamps and eating sea grass. However, we now know that hadrosaurs were land-dwelling dinosaurs. They lived in what is now the following areas: Alberta, Canada; Alaska; Wyoming; New Jersey; Montana.

Edmontosaurus were discovered in the year 1917, from a fossil in Edmonton Rock Formation, which is located in Alberta, Canada. They were named by a man named Lawrence M. Lambe, who the hadrosaur Lambeosaurus was named after

What do we need to learn?

• Where they actually lived
• Their speed (since only one badly wethered footprint has ever been found but has now been referred to Wichhelmipus)
