Edmontosaurus (after where it was found, in southern Alberta in what used to be called "Lower Edmonton" in the Horseshoe Canyon Formation, Alberta, Canada and Greek sauros meaning lizard) was a hadrosaurid dinosaur genus from the Maastrichtian, the last stage of the Cretaceous Period, 71-65 million years ago. Depending on the species, a fully-grown adult could have been up to 9 metres (30 ft) long, and some of the larger specimens reached the range of 12 metres (40 ft)[1] to 13 metres (43 ft) long. Its weight was in the region of 4.0 tonnes (4.4 short tons), making it one of the largest hadrosaurids. It resembled Maiasaura in its shape and posture, though the two genera were quite different in size.
