Abstract
Ankylosaurian dermal armour elements from the Fuente Espudia locality, near Salas de los Infantes (Burgos Province), are described. These remains have been recovered from red clays of the Urbion Group, which belong to the Weald facies of the western Cameros Basin, of possible Barremian-Aptian age (Lower Cretaceous). Based on their general form, two caudal spines are here assigned to the nodosaurid Polacanthus . This represents the first mention of this genus in the Iberian Peninsula. Previous finds in the same area could also be assigned to this armoured dinosaur.
