Taxonomic history of the currently existing nominal taxa of the European rhabdodontomorph dinosaurs. Individual species are shown in a different shade of color for the particular genus (blue for Rhabdodon, green for Mochlodon, orange for Zalmoxes, red for Obelignathus gen. nov.; other valid taxa are in purple and violet, while the invalid taxa are in white). The first use of the name is shown in bold font. Empty spaces indicate that the taxon was not mentioned in the given paper. Note that originally Rhabdodon priscus was spelled R. priscum^18,25, and Mocholodon suessi was ‘Iguanodon’ suessii¹⁷.
