Neosaurus was one of the last dinosaurs described by Smithsonian Dinosaur Curator C. W. Gilmore. It was renamed later that same year by Gilmore & Stewart as Parrosaurus because the name Neosaurus was preoccupied by another animal species. Originally thought to be a sauropod, this dinosaur was transferred to the hadrosaurs (duckbill dinosaurs) by Baird & Horner in 1979.
