Abstract

DERMAL ARMOUR ELEMENTS OF THE ANKYLOSAUR DINOSAUR POLACANTHUS OWEN, 1865, FROM THE LOWER CRETACEOUS OF MORELLA (CASTELLÓN, SPAIN). Isolated dermal armour elements of an ankylosaur from the lower Aptian Arcillas de Morella Formation at Morella (Castellón, Spain) are described herein. These elements are presacral and caudal spines, fragments of sacropelvic shield, keeled scutes and keeled ossicles. The possession of ungrooved presacral spines and a sa-cropelvic shield composed of irregularly arranged bosses and small tubercles are some of the features shared with Polacanthus. Thus we tentatively refer these elements to Polacanthus sp. This assemblage of Polacanthus dermal armour elements is currently the most important outside England. Furthermore, the new evidence of this ankylosaur in the Iberian record corroborates the great similarity between the Barremian—Aptian dinosaur faunas both the British and Iberian records.
