RT Journal Article T1 Nuevos restos de ornitópodo (Ornithischia: Ankylopollexia) del Jurásico Superior de Tazones, Asturias (Formación Tereñes) T1 New ornithopod remains (Ornithischia: Ankylopollexia) from the Late Jurassic of Tazones, Asturias, North Spain(Tereñes Formation) A1 Ruiz Omeñaca, José Ignacio A1 Piñuela, Laura A1 García Ramos, José Carlos AB Two dorsal vertebral centra of an ornithopod dinosaur from the Late Jurassic of the Principality ofAsturias (north Spain) are described. They come from an outcrop of the Tereñes Formation (Kimmeridgian)at Tazones harbour (Villaviciosa). They are identified as a juvenile indeterminate ankylopollexian. Thevertebrae are the first dinosaur bony remains found to date in the Tereñes Formation, where dinosaurfootprints are, on the other hand, very abundant. We estimate that the owner of the vertebrae was 4.6-5meters in total length. When adult, the Tazones ankylopollexian were capable of make the big ornithopodfootprints recovered in the Kimmeridgian-Tithonian of both Asturias and Portugal, made by individuals upto 2.8 m in hip height (~7.8 m of total length) YR 2008 FD 2008 LK http://hdl.handle.net/10272/8195 UL http://hdl.handle.net/10272/8195 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
