 "Mantellisaurus atherfieldensis" by David Bruce Norman (2012), and made the holotype of a separate genus and species "Mantellodon carpenteri" by Gregory S. Paul (2012).The generic name combines Mantell's name with a Greek "odon", "tooth", analogous to "Iguanodon".The specific name honours Kenneth Carpenter for his work on dinosaurs in general and iguandonts in particular.
