Abstract
Se estudian los materiales que forman la base de la transgresión del Cretácico superior en la zona Atienza-Sigüenza. Se han encontrado Chofiatticeras discoidale, Ch, segne, Ingridella sp Jeanrogericeras combesi y Mammites nodosoides del Turoniense inferior-medio (zonas III, IV y V) que permiten establecer para esta región una biozonación basada en especies poco frecuente en el País Vasco y la región de Soria.
The basal sediments of the Upper Cretaceous in the Atienza-Sigüienza area are studied in this note. Choffaticeras discoidale, Ch. Segne, Ingridella sp, Jeanrogericeras combesi and Mammttes nodosoides of Lower-Middle Turonian Age (Zones III, IV, V) have been found and a biozonation by means of rare Ammonites of the Basque Country and Soria region has been established.
