A small dinosaur vertebra from the Late Jurassic of the Principality of Asturias (north Spain) is described. It comes from an outcrop of the Lastres Formation (Kimmeridgian) at Tazones harbour (Villaviciosa) and it is identified as a dorsal vertebral centrum of a juvenile ornithopod. After a revision of the European record of Late 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 undoubted Late Jurassic age.
