Craspedodon

Craspedodon (meaning 'edge tooth') is an extinct genus of ornithischian dinosaur from the Late Cretaceous Lonzée Member of Belgium. Only a single species, C. lonzeensis, is known.

Dollo identified Craspedodon from three teeth in the collections of the Museum of Natural Sciences in Brussels, from the Lonzée Member, finding the most similarities with species of Iguanodon amongst ornithischians. The genus name is a reference to the strong ridges that cross the teeth, while the species name is a reference to the locality where it was found. Dollo specified the Lonzée Member as being middle Senonian in age, which is now understood to be Coniacian to Santonian.
