Hexagonites


''Hexagonites'' is an extinct genus from the nautiloid order, Nautilida which includes the genus ''Nautilus'' found living in the tropical western Pacific. ''Hexagonites'' is included in the family Tainoceratidae, part of the superfamily Tainocerataceae (Kummel, 1964)
''Hexagonites'' is based on an incomplete, crushed specimen from the Permian of China. Its shell is very evolute, with an hexagonal whorl section, and six rows of tubercles, in pairs on the ventrolateral and dorsolateral shoulders. The suture has shallow lobes. (ibid)
