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.[1]

Discovery and naming

IRSN R 59 (left), a tooth from ISRNB R. 58 (middle) and IRSN R 105 (right)

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.[2]

The teeth were initially compared to those of Iguanodon, and the species Craspedodon lonzeensis was named and described by Louis Dollo in 1883,[1] although it is considered a nomen dubium.[2]

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.[2]
