Implicaciones de la presencia de huellas de dinosaurios en el limite cartografico entre las facies Purbeck y Weald de la Cuenca Iberica suroccidental, en el entorno de Losilla (Valencia)

Abstract

Some sauropod footprints has been found at the boundary between Purbeck and Weald fades in the outskirts of the Losilla de Aras village (Valencia). The presence of dinosaur traces is in contradiction to the existence of an unconformity, that separate the Upper Jurassic Villar del Arzobispo Fm. from the Lower Cretaceous El Collado Fm in this area. This allow us to consider that the Jurassic-Cretaceous limit is present into the lower part of the former mapped Weald facies
