Abstract

Con el fin de actualizar y ampliar los trabajos paleontológicos previos sobre el Cretácico Superior del Norte de Guadalajara, se han estudiado dos columnas estratigráficas en las localidades de Pálmaces de Jadraque y Veguillas. Las facies analizadas representan la transgresión y el comienzo de la regresión del Cenomaniense superior-Turoniense inferior. El material paleontológico recogido se ha estudiado sistemáticamente, identificándose: Seis taxones de bivalvos, dos taxones de gasterópodos, dos taxones de cefalópodos y dos taxones de equinoideos.

Resumen (otros idiomas)

In order to update and expand the previous palaeontological studies about the Upper Cretaceous of the North of Guadalajara two stratigraphic sections have been studied near the villages of Pálmaces de Jadraque and Veguillas (Figs. 1, 2). Studied facies correspond to three different formations (Arenas, arcillas y calizas de Santa María de las Hoyas, Margas de Picofrentes and Dolomías de la Ciudad Encantada) that represent the transgression and the beginning of the regression of the upper Cenomanian-lower Turonian. The collected palaeontological material has been studied systematically and thirteen taxa have been identified: six bivalves, two gastropods, two cephalopods and two echinoids. Besides, two different biotic associations have been identified. The first one corresponds to a relative shallow environment with a fauna of epifaunal bivalves and gastropods that are located in the Santa María de las Hoyas Formation. The second represents a deeper environment with infaunal bivalves, gastropods, ammonoids and echinoids, and is located in the Picofrentes Formation.
