• Resumen

  • The discovery of new stegosaurian remains from a site in Riodeva (Teruel, Spain) included in the Villar del Arzobispo Formation evidences the strong presence of these plated dinosaurs in the Jurassic-Cretaceous transition of the Iberian Range -specifically in the tidal and supratidal systems which gave birth to this lithostratigraphic unit. These fossils, which consist of four vertebral centra, are attributed to Dacentrurus armatus.Their abundance can prove that the slight variations which can be seen among different individuals -sometimes between specimens really close geographically and temporally- actually correspond to intraspecific variation of this taxon.
