''Gundolficeras'' is member of the Tornoceratidae, (goniatitid ammonites), from the Late Devonian named by Becker, 1995 and assigned to the Falcitornoceratinae. The type species is ''"Lobotornoceras" bicaniculatum''. ''Gundolficeras'' has a compressed or somewhat inflated shell that may have ventrolateral furrows and an open or closed umbilicus at medium stages. The suture has a small ventral lobe and on either side, a narrow, asymmetric, rounded or pointed adventitious lobe and a high saddle located mid-flank. ''Gundolficeras'' differs from its partly contemporary, but slightly older relative ''Falcitornoceras'' in the details of the suture and in sometimes having an open umbilicus. ==References== *''Gundolficeras'' in (GONIAT Online ) 6/9/12 *(Falcitornoceratinae ) Paleobio Database. 6/9/12 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「Gundolficeras」の詳細全文を読む スポンサード リンク
