概要

• 論文の詳細を見る

• Four ammonoid species, Propinacoceras sp., Agathiceras sp., Mexicocerasl sp. and Roadoceras sp., are described from the upper Takakurayama Formation in the Takakurayama area, Abukuma Mountains, northeast Japan. These ammonoids indicate a Middle Permian (Wordian) age. The Takakurayama ammonoid specimens are reworked fossils, probably derived from shallow marine continental shelf to a deep-sea basin by sediment-gravity flows in Late, Permian.
