Cave sediments preserve unaltered a broad range of proxies that can be used for past environment change reconstructions. Paleomagnetic properties of sediments, U/Th-datings, vertebrate fossils and invertebrate fossils were used as proxies in an integrated study about cave sediments. Invertebrate fossil remains from cave sediments can give indications on sediment origin, conditions for deposition and surface paleoenvironment. Samples of suspended sediments from several caves were taken from Romania and Slovenia. Fragments of aquatic (cladocerans) and terrestrial (mites, insects) invertebrates were identified at species or group level. The presence of the fossils at different sedimentary levels are explained in the frame of the paleoenvironmental context and are supporting the proposed hypotheses about time and condition for sediment deposition and paleogeographic evolution.
