RT Journal Article T1 El primer diente de ornitópodo del Jurásico Superior de España (Asturias) T1 The first ornithopod tooth from the Late Jurassic of Spain (Asturias) A1 Ruiz Omeñaca, José Ignacio A1 Piñuela, Laura A1 García Ramos, José Carlos AB One isolated ornithopod dinosaur tooth from the Principality of Asturias (northern Spain) is studied in this work. It has been found in the Aranzón cliffs (Villaviciosa municipality), in an outcrop of the deltaic Lastres Formation (Kimmeridgian). It is a terminally resorbed tooth, identified by its ornamentation and resorption facets as a left maxillary crown. Its morphology, with a prominent primary ridge distally displaced in labial view, is similar to that of maxillary teeth of Early Cretaceous basal iguanodontoids, but also to that of the Late Jurassic camptosaurids Camptosaurus dispar from North America and Camptosaurus prestwichii and Draconyx loureiroi from Europe. It recalls also the Latejurassic dryosaurid Dryosaurus lettowvorbecki from Tanzania, so it is assigned to Dryomorpha indet. It represents the first ornithopod tooth described from the Jurassic of Spain YR 2010 FD 2010 LK http://hdl.handle.net/10272/7865 UL http://hdl.handle.net/10272/7865 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 15 jun 2026
