Only a few teeth have ever been found, which were described as similar to those of Iguanodon. Craspedodon lonzeensis, described by Louis Dollo in 1883, is the type species, although it is considered a nomen dubium since it is based on fragmentary material (teeth only).
The discovery of a limited number of teeth has provided insight into their similarity to those of Iguanodon. Craspedodon lonzeensis, described by Louis Dollo in 1883, serves as the type species, although its validity is tempered due to its reliance on fragmentary evidence (teeth alone).
