Abstract.
This paper describes microgastropod fossils from the Kasimovian (late Carboniferous) limestone float collected from the Mizuboradani Valley, Fukuji, Okuhida-onsen-gou, Takayama City, Gifu Prefecture, central Japan. The microgastropod assemblage consists of a diversity of larval and/or early juvenile shells and represents late Palaeozoic cosmopolitan taxa, including Euomphalidae, Pleurotomarioidea, Anomphalidae, Naticopsidae, Trachyspiridae, Goniasmatidae, Orthonematidae, Pseudozygopleuridae, Subulitidae, Meekospiridae and Streptacididae. The microgastropod assemblage bears some resemblances to those from the early Carboniferous of New South Wales, Australia, and those from the latest Permian of Guangxi Province, China.
We would like to express our sincere thanks to the late Satoru Yamakoshi (Fukuji, Gifu) for his support during the fieldwork. We thank Alexander Nützel (Geobio-Center, Ludwig Maximilians University of Munich) and Andrzej Kaim (Institute of Paleobiology, Polish Academy of Sciences) for critically reading the manuscript and providing valuable comments.
