Marine-mollusc fossils (Mollusca: Bivalvia and Gastropoda) and their paleoenvironmental interpretation from the Situs manusia purba Sangiran area

Research on mollusc fossils on the Sangiran area is not widely known. Sangiran area is known as one of the world prehistoric sites because the area has uncovered many fossil organisms. Sangiran stratigraphic chart extends from the oldest geological time to recent one, i.e.: Late Pliocene to Holocene. The stratigraphic chart is divided into four formations, i.e., Kalibeng, Pucangan, Kabuh and Notopuro. Each formation is characterized by different geological sediments and distinctive fossil organisms. The Laboratory of Bioanthropology and Paleoanthropology, Faculty of Medicine, UGM has frequently been conducting excavation in the Sangiran area. Fossil of marine molluscs that had been found so far is not yet identified. The aims of this research are: to identify fossil collection of marine-molluscs to study its diversity during the Pleistocene, and to interpret the paleo-environment of where those fossils were found. The results obtained: from 35 samples of bivalve there are six orders with 12 families and 3...
