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

Discovery and naming

The holotype, specimen IRSNB R. 58, which consists of two teeth, the paratype, specimen IRSN R 105, a tooth, and a referred specimen, IRSN R 59, a tooth, were all discovered in the Glauconie de Lonzée Formation, in Belgium. The teeth were initially compared to those of Iguanodon, and the species Craspedodon lonzeensis was named and described by Louis Dollo in 1883, although it is considered a nomen dubium.

Classification

Craspedodon was long thought to be an iguanodontian, but Godefroit & Lambert (2007) suggested that it was actually a neoceratopsian, perhaps closer to Ceratopsoidea than Protoceratopsidae. If the reidentification is correct, Craspedodon would be the first neoceratopsian known from Europe.
