Edmontosaurus annectens (meaning “connected lizard from Edmonton”) is a duck-billed and flat-headed (hadrosaurid) dinosaurs at the end in the Cretaceous Period, in what is today North America.
It was a huge animal that could reach up to 12 meters (39 feet) and possibly 15 metres (49 feet) in length, with an exceptionally long and low skull. It has been identified from a variety of specimens, including 20 partial to complete skullsthat were found within the U.S. states of Montana, South Dakota, North Dakota, Wyoming and Colorado and in the Canadian provinces of Saskatchewan.
It is known for its long history of taxonomy and specimens have been classified into groups like Diclonius, Trachodon, Hadrosaurus, Claosaurus, Thespesius, Anatosaurus and Anatotitan.
