Edmontosaurus annectens (meaning "connected lizard from Edmonton"), often colloquially and historically known as Anatosaurus (meaning "duck lizard"), is a species of flat-headed saurolophine hadrosaurid dinosaur from the late Maastrichtian age at the very end of the Cretaceous period, in what is now western North America.
Most known complete Edmontosaurus annectens and Edmontosaurus regalis skulls. Edmontosaurus is currently regarded as having two valid species: the type species E. regalis and E. annectens. [3] [17] E. regalis is known only from the Horseshoe Canyon Formation of Alberta, dating from the late Campanian age of the late Cretaceous period.
Anatotitan copei is now regarded as a synonym of Edmontosaurus annectens by most researchers. [20] The majority of dinosaur skin impressions are referable to the Hadrosauridae. In North American specimens from the Maastrichtian age, skin impressions are 31 times more abundant in association with hadrosaurid specimens than with any other group.
Edmontosaurus regalis is a species of comb-crested hadrosaurid dinosaur. Fossils of E. regalis have been found in rocks of western North America that date from the late Campanian age of the Cretaceous Period 73 million years ago, but it may have possibly lived into the early Maastrichtian .

Instead, other sites in the American West would come to provide many very complete specimens that would form the backbone of hadrosaur research. One such specimen was the very complete AMNH 5060 (belonging to Edmontosaurus annectens), recovered in 1908 by the fossil collector Charles Hazelius Sternberg and his three sons in Converse County ...
Tyrannosaurus equals Edmontosaurus in U3 and in L3 comprises a greater percentage of the large dinosaur fauna as the second-most abundant taxon after Triceratops, followed by Edmontosaurus. This is surprisingly consistent in (1) the two major lag deposits (MOR loc. HC-530 and HC-312) in the Apex sandstone and Jen-rex sand where individual bones ...
The Edmontosaurus was given the green light, but depending on species, shouldn't it have a skin crest and more of a dewlap? FunkMonk 17:29, 9 March 2023 (UTC) With a slightly lengthened skull I think it passes for annectens. Lythronaxargestes (talk | contribs) 18:13, 9 March 2023 (UTC) Couldn't that be explained by foreshortening?
