Abstract

広島県神石郡油木町宗兼に分布する備北層群神石累層下部(中期中新世初頭)より産したオキナワアナジャコThalassinia anomala(Herbst)を記載した。T. anomalaは現生種で, インド-西太平洋の熱帯地域のマングローブ沼生活者であり, その産出を中新世まで遡らせた。この種の産出は, 中期中新世初頭の西南日本の熱帯的古環境を支持する。

Thalassina anomala (Herbst, 1804), a thalassinid decapod, is described from the early Middle Miocene Bihoku Group exposed at Munekane, Yuki-cho, Jinseki-gun, Hiroshima Prefecture, Southwest Japan. Thalassina anomala is a living species which inhabits mangrove swamps and this occurrence shows the existence of mangrove swampy paleoenvironment in the Middle Miocene. It is closely related to the tropical spike recognized in the early Middle Miocene of Southwest Japan.
