Primera descripción de restos esqueléticos de dinosaurio ornitópodo en la Formación Villar del Arzobispo (tránsito Jurásico-Cretácico): yacimiento de Cerrito del Olmo (Alpuente, Valencia)

Abstract

The Villar del Arzobispo Formation (Tithonian-Berriasian) in Teruel and Valencia provinces (SE Iberian Range) has yielded abundant skeletal remains of dinosaurs, mainly of sauropods and stegosaurs. Three vertebrae collected in the locality of Cerrito del Olmo I (Alpuente, Valencia province), two of them previously referred to the stegosaurid Dacentrurus armatus, belong in fact to an ornithopod. The material consists of one cervical and two caudal centra that preserve the base of the neural arch fused to the centrum. These remains are here assigned to Ornithopoda indet. on the basis of the combination of several characters more frequent in ornithopods than in stegosaurs. This is the first description of ornithopod skeletal remains from the Villar del Arzobispo Formation
