Nuevo rastro de ignitas de cocodrilo en la Aloformación Huérteles de la Cuenca de Cameros: yacimiento del Barranco de Valdelavilla (Valdelavilla, Soria, España)

Abstract

The tracksite located in Barranco de Valdelavilla (Valdelavilla, Soria, Spain) had provided so far theropods, sauropods and pterosaurs tracks. It has now provided a new type of footprints, "cocodrile tracks", which represents the second important trackway found in the province of Soria (the first one is in Fuente Lacorte, Bretún). These footprints appear on sandy limestones from Huérteles Alloformation, which belongs to the Oncala group in the Cameros Basin, and it is estimated to exist since the Berrisian age. It is formed by 8 five fingered footprints from hands, well market, and 8 footprints of feet with four toes each. This morphology indicates that it was made by a medium crocodile, probably from the Goniopholidae family.
