Note: Genus name introduced by the American paleontologist Othniel Charles Marsh (1831-99) in "Notice of New Dinosaurian Reptiles from the Jurassic Formation," The American Journal of Science and Arts, vol. 114 (3rd series, vol. 14) (Jul.-Dec., 1877), no. 84, pp. 514-16. The combining element allo- is apparently meant to represent its distinctness: "This genus may be distinguished from any known Dinosaurs by the vertebræ, which are peculiarly modified to ensure lightness" (p. 515).
