RT Journal Article T1 Una vértebra de un pequeño ornitópodo (Dinosauria: Ornithischia) del Kimmeridgiense (Formación Lastres) de Tazones (Villaviciosa, Asturias) T1 A small ornithopod vertebra (Dinosauria: Ornithischia) from the Kimmeridgian (Lastres Formation) of Tazones(Villaviciosa, Asturias, North Spain) A1 Ruiz Omeñaca, José Ignacio A1 Piñuela, Laura A1 García Ramos, José Carlos AB A small dinosaur vertebra from the Late Jurassic of the Principality of Asturias (north Spain) is described. Itcomes from an outcrop of the Lastres Formation (Kimmeridgian) at Tazones harbour (Villaviciosa) and it isidentified as a dorsal vertebral centrum of a juvenile ornithopod. After a revision of the European record ofLate Jurassic ornithopod, we conclude that the Tazones vertebra could pertain both to a «hypsilophodontid»or a dryosaurid. It represents the oldest ornithopod bony remain in Spain, and the first one of undoubtedLate Jurassic age YR 2007 FD 2007 LK http://hdl.handle.net/10272/8432 UL http://hdl.handle.net/10272/8432 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
