• Resumen

  • One isolated ornithopod dinosaur tooth from the Principality os Asturias (northern Spain) is studied in this work. Ita has been found in the Arazón cliffs (Villaviciosa municipality), in an outcrop of the deltaic Lastress 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 Late Jurassic dryosaurid Dryosaurus lettowvorbecki from Tanzania, so it is asigned to Dryomorpha indet. It represents the first ornithopod tooth described from Jurassic of Spain.
