Resumen

We describe a dinosaur caudal centrum from an outcrop of the Vega Formation (Kimmeridgian) in Colunga (Asturias Principality, Northern Spain). It is very similar to the centra of mid-caudal vertebrae of some stegosaurs, like Dacentrurus and Stegosaurus, which are characterized by the presence of well developed haemal processes on the posteroventral corner. Because this character is not diagnostic to the generic level, the vertebral centrum is assigned to Stegosauria indet. This is the first evidence of stegosaurs in this geological formation.
