Rhabdodon (meaning "fluted tooth") is a genus of ornithopod dinosaur that lived in Europe approximately 70-66 million years ago in the Late Cretaceous.

It is similar in build to a very robust "hypsilophodont" (non-iguanodont ornithopod), though all modern phylogenetic analyses find this to be an unnatural grouping, and Rhabdodon to be a basal member of Iguanodontia.

[citation needed] Isotope analysis shows that Rhabdodon, along with its smaller cousin Zalmoxes, ate C3 plants.

Dinosaurian fauna from the Marnes Rouges Inférieures Formation include Ampelosaurus, an animal classified as Dromaeosauridae indet., and an indeterminate ankylosaur.

is from the latest Cretaceous aged Lo Hueco region in the Villalba de la Sierra Formation.

[8] The study showed that Lo Hueco was near the coast of the Tethys Sea,[8] a large seaway through southern Europe and northern Africa.
