''Falcitornoceras'' was named by House and Price, 1985, and is the type genus for the subfamily Falcitornoceratinae. The shell of ''Falcitornoceras'' is strongly involute, lacking an umbilicus. Juvenile stages have falcate ribs which cross the ventral rim; the ventro-lateral area bears weak to strong furrows. The adventitious lobe, high on the flank, is rounded or subacute and the lateral lobe has an inconspicuous saddle at the umbilical seam. ''Falcitornoceras'' is slightly older than ''Gundolficeras'' and somewhat younger than ''Phoenixites'', close relatives, although temporally overlapping both. ==Distribution== Devonian of France, Poland and Spain. 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Falcitornoceras」の詳細全文を読む スポンサード リンク
