Abstract
El sur de la Cordillera Ibérica se caracteriza por presentar decenas de
yacimientos de dinosaurios incluidos en la Formación Calizas, Areniscas y
Arcillas de Villar del Arzobispo (Titoniense-Berriasiense). Aquí se describen
nuevos fósiles de dinosaurios de dicha unidad litoestratigráfica procedentes
de la Subcuenca de Peñagolosa (Cuenca del Maestrazgo) en la provincia de
Teruel. En concreto, se describe un centro vertebral caudal de un saurópodo
asignado a Diplodocoidea indet. procedente de El Castellar. Igualmente se
informa del hallazgo de la mitad apical de un gran diente de terópodo megalosáurido
de Formiche Alto, conocido con anterioridad sólo por la parte
central de su corona y que representa el mayor diente de carnívoro descrito
en España, mayor incluso que otro hallado en Riodeva (Teruel). Asimismo,
en Formiche Alto se sitúa un nuevo yacimiento de icnitas de dinosaurios saurópodos
y ornitópodos que se presenta de forma preliminar. Estos hallazgos
permiten completar la diversidad faunística de dinosaurios con afinidades
jurásicas que habitaron los sistemas mareales e intermareales de la Formación
Villar del Arzobispo en la Subcuenca de Peñagolosa
The South of the Iberian Range is characterised by the presence of dozens of sites with dinosaurs included in the Limestone, Sandstone and Clays of the Villar del Arzobispo Formation (Tithonian-Berriasian). Here are described new findings in that lithostratigraphic unit of the Peñagolosa subbasin (Maestrazgo Basin) in Teruel province. Concretely a sauropod caudal centrum from El Castellar assigned to Diplodocoidea indet. is described. Likewise we inform about the discovery of the apical section of a large Megalosauridae theropod tooth from Formiche Alto, only known before by the central section of the crown and that globally would represent the largest theropod tooth described in Spain, bigger even than other found in Riodeva (Teruel).Also in Formiche a new dinosaur tracksite called Masía de la Cañada has yielded and is presented from a preliminary point of view. These discoveries allow us to complete the faunistic diversity in dinosaurs with Jurassic affinity that lived in the tidal and intertidal systems of the Villar del Arzobispo Formation in the Peñagolosa sub-basin
