Gilmore pieced together what he could of this basal iguanadont or hadrosaur dinosaur and attributed it to the genus Mandschurosaurus and continued on with all of the other fossils on his plate. Over 60 years later those remains and others attributed to the species were reviewed by Dr. Michael K. Brett-Surman (then of Johns Hopkins, currently the Smithsonian; coincidentally he is the first Smithsonian employee to have ever conducted a PhD strictly on dinosaurs!) in an all encompassing review of hadrosaur dinosaurs. His analysis determined that Gilmore's Mandschurosaurus was in fact derived enough in its own right that it warranted its own genus. The type is now known as Gilmoreosaurus mongoliensis Gilmore 1933. This may confuse some as it appears that Gilmore named the dinosaur after himself, but he most certainly did not as the genus is actually attributed as Gilmoreosaurus Brett-Surman 1979. Since that time two other species have been assigned to the genus.
