Identification of faunal fossil finding from Tanjungan village Kemlagi district, Mojokerto regency

Mojokerto is one of the important areas for paleoanthropological-archaeological studies in Indonesia. In the Mojokerto area, specifically in Perning Village, Homo erectus fossils were found, as well as vertebrate fauna fossils. In another area, namely in Sumberdadi Hamlet, Sumbersari Village, Dawar Blandong District, vertebrate fauna fossils were also found. In addition to these two areas, vertebrate fossils are also known to be found in Tanjungan Village, Kemlagi District, Mojokerto Regency. The purpose of this study is to identify the findings of fauna fossils from Tanjungan Village, Kemlagi District, Mojokerto, and then describe the habitat of the types of fauna fossils remains. The identification of the findings is based on the morphological characteristics seen in the fossil fragments. Five fauna species were obtained from the identification results, namely Bovidae, Stegodon sp., Carcharhinidae, Ostreidae, and Potamididae. These results provide an overview of the ancient environment of Tanjungan Village, in the forms of an original marine environment, a brackish-water environment, and ultimately a continental environment.
