Temporal range: Cretaceous, 100–65 mya
Rhabdodontids were herbivorous ornithopod dinosaurs from the Cretaceous. They were similar to large, robust hypsilophodonts, with deep skulls and jaws. The family were defined as "the most recent common ancestor of Zalmoxes robustus and Rhabdodon priscus and all the descendants of this common ancestor". In 2005, Paul Sereno defined the family as "the most inclusive clade containing Rhabdodon priscus but not Parasaurolophus walkeri". The Rhabdodontidae includes the type genus Rhabdodon, Zalmoxes, and possibly Mochlodon and Muttaburrasaurus. Rhabdodontid fossils have been found in Europe and Australia in formations from 100 to 65 million years ago.
