Type species
Lentitornoceras materni gen. et sp. nov.
Diagnosis
Genus of the subfamily Tornoceratinae with strongly compressed conch, umbilicus closed in the adult stage. Without ventrolateral grooves. Ornament with biconvex growth lines, without ribs. Sutural formula E A L I; adventive lobe broadly rounded, asymmetric with steep dorsal flank; ventrolateral saddle narrow.
Etymology
After the Latin nomen ‘ lens ’ = ‘lentil’, because of the conch shape, and the reference to the genus Tornoceras .
Included species
Only the type species.
Remarks
Lentitornoceras gen. nov. is easily distinguished from all other tornoceratids by its extremely discoidal conch shape. Furthermore, the course of the growth lines shows differences to other genera; in
Lentitornoceras a clear dorsolateral projection is developed, which is only very indistinct in the other genera.
