Phlycticeratinae : ウィキペディア英語版 | Phlycticeratinae Phlycticeratinae is a subfamily included in the Oppeliidae established for the genus ''Phlycticeras''. Although there seems to be some affinity with Stephanocerataceae it is most likely descended from some bathonian member of the Oppeliinae. The genus ''Phlycticeras'' is involute, feebly but coarsely ribbed, tuberculate, strongly strigate, with serrated keel and moderately complex sutures. ==References== W.J. Arkell, et al. 1957.
