Wealden ornithopod dinosaur Hypsilophodon from the Capas Rojas Formation (lower Aptian, Lower Cretaceous) of Morella, Castellon, Spain

ABSTRACT

The ornithopod dinosaur Hypsilophodon (presumably H.foxii) has been recorded from outside of the classic English Wealden outcrops. The material studied (a metatarsal and phalangeal mash) comes from the Capas Rojas Formation at Morella (Province of Castellon, Spain) and is early Aptian in age. Both the metatarsal and fibular shafts are highly pneumatized. A simple method of measuring the extent of pneumatization is proposed. This additional species from the Spanish locality increases the similarity between faunas of the Wealden and Capas Rojas.
