The description of a specimen of Aturia coxi from the uppermost Miocene of central Japan provides additional data on this poorly known Neogene species. Aturia coxi Miller is the youngest representative of this nautiloid genus, which is known from the middle to upper Miocene formations of the Indo-Western Pacific and became extinct at the end of Miocene. In addition to the presence of Aturia coxi, the abundance of tropical and subtropical benthic molluscs indicates that tropical molluscan faunas invaded mid-latitude waters around Japan in the latest Miocene. The extinction of Aturia and other Miocene molluscan genera marks the end of the Miocene Epoch.
