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 agespaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/OrnithopodaHypsilophodontidaeDryosauridaeCamptosauridaeLate Jurassicjournal articleopen access
