       Craspedodon is‭ ‬what is known as a tooth taxon in that the entire genus has been described upon the basis of only a‭ ‬few teeth.‭ ‬When first described by Louis Dollo in‭ ‬1883,‭ ‬he noted that the teeth were similar to those of Iguanodon,‭ ‬and so for well over a hundred years Craspedodon had been established as a possible‭ (‬though dubious‭) ‬iguanodont dinosaur.
       A new study of these teeth in‭ ‬2007‭ ‬by Godefroit and Lambert however has raised a startling new theory.‭ ‬When they studied these teeth,‭ ‬they compared to other plant eating dinosaurs and found them to be most similar to neoceratopsian dinosaurs.‭ ‬If this analysis is correct,‭ ‬then Craspedodon would actually be the first official record of a ceratopsian dinosaur living in Europe,‭ ‬an area that had long been presumed to have an absence of ceratopsian dinosaurs which traditionally have been associated with Far East Asia and North America.
