Lophiotoma
Lophiotoma is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids.
Fossils of this genus have been found in many places in the Indo-Pacific, but also going as far back as 61.7 Ma in paleocene strata of Alabama, USA.
Original description
Although having the small smooth embryo of a single whorl, polished surface and obsolete lines of growth, characterizing Pleurotoma, this genus may be recognized at once by the relatively shorter and stouter form as a rule, less elongate and straighter beak, which is strongly tapering in certain large forms like line unedo, finer, more acutely elevated and less close-set spiral carinae, with a usually distinct and even, finely lineolate concavity from the peripheral carina to the suture or subsutural collar, the latter being generally present and by the deep anal sinus formed centrally on, and not behind, the peripheral carina, the latter being more strongly elevated andusually subduplex.
