This list of ornithopod type specimens is a list of fossils serving as the official standard-bearers for inclusion in the species and genera of the dinosaur clade Ornithopoda, which includes the line of herbivorous dinosaurs culminating in the duck-billed hadrosaurs. Type specimens are definitionally members of biological taxa and additional specimens can only be "referred" to these taxa if an expert deems them sufficiently similar to the type.
