Zusammenfassung
This study presents paleoecological aspects of the Zarzamora Cave karstic site (Segovia, Spain). This site is a Late Pleistocene cave deposit in a limestone outcrop that extends from the crystalline piedmont of the Sierra de Guadarrama to the Tertiary Castilian Plateau. The Zarzamora Cave is a small gallery with a NE-SW direction and approximately 1 m high, 2 m wide and around 7 m in longitudinal accessible development. The total length is still unknown due to the sediment infilling. The �keyhole shaped� section suggests that the karstic system evolved from phreatic to vadose conditions. The sedimentary infilling is around 90 cm thick and four stratigraphic units have been identified. The upper three units are made of crystalline dolomite matrix with macro and microvertebrate fossils. The lower unit is made of plastic clay with no paleontological evidence. The entrance to the Zarzamora Cave is a few meters away from the entrance of the Búho Cave. It was during the excavation of the latter in the late years of the 1980s that the entrance to the Zarzamora Cave was found. Then, the site was divided in three sectors: Búho Cave, Zarzamora Cave and Cata Exterior
