Dinofact #109
Edmontosaurus' taxonomic history is quite complicated, with specimens belonging to E. annectens being classified as many other species, such as Hadrosaurus, Diclonius, and Claosaurus, as well as the dubious genera Trachodon and Thespesius, and, now synonymous with Edmontosaurus, the genera Anatosaurus and Anatotitan.
