Rhabdodontids were herbivorous ornithopod dinosaurs from the Cretaceous Period. Rhabdodontids were similar to large, robust iguanodonts, with deep skulls and jaws. The family was first proposed by David B. Weishampel and colleagues in 2003.[1] Rhabdodontid fossils have been found in Europe in formations dating to the Late Cretaceous.
Classification
There are differing opinions as to the constituents of Rhabdodontidae. Originally they were defined as the last common ancestor of Zalmoxes robustus and Rhabdodon priscus.[citation needed] Later, Paul Sereno proposed a new definition, the most inclusive clade containing Rhabdodon priscus but not Parasaurolophus walkeri.[2] More recently, a morphological diagnosis was proposed, that excluded Muttaburrasaurus, unlike Sereno's definition. The clade Rhabdodontomorpha was coined to contain the larger group.[3] The following cladogram was recovered by Dieudonné et al. (2016).[3]
Evolution
Traditionally, it has been thought Mochlodon and Zalmoxes were insular dwarfs. However, Ősi et al. (2012) proposed that Rhabdodon underwent gigantism on the mainland, as opposed to Zalmoxes and Mochlodon experiencing nanism on island habitats.[4]
