Et enkelt Exemplar fra Sylt er 65 mm. langt,

Il Conus poulsenii, proveniente dal Tortoniano di Sylt, in Germania, è ritenuto differente dal Conus antidiluvianus a causa dei noduli più grossolani e presenti in numero inferiore ⁽¹⁾.

In 1874 Mørch (p. 291) introduced Conus (Conilithes) poulsenii, based on specimens from Sylt (Germany) and Gram, Spandet, Esbjerg and Sandfuldgaarde (Denmark), all late Miocene (Tortonian) in age ⁽¹⁾. The single specimen from Sylt had a shell height of 65 mm. The shell was described as different from C. antidiluvianus Brocchi in having fewer and coarser knobs (‘differt nodulis coronæ majoribus et paucioribus’) and Conus ‘antediluvianus’ Beyr. non Brug.’ is mentioned as a synonym.

Nyst proposed the new name Conus bruguierii for the species represented by Brocchi (1814, pl. 2, fig. 11). Nyst’s name, however, is a junior synonym of Conus apenninicus (Bronn,1838) ⁽¹⁾.

The Gram Formation is a geological formation in Gram, Denmark. It preserves fossils dating from the Miocene period. The formation consists of three layers: the glauconite-rich, the Gram Clay, and the Gram sand.

Conus poulsenii var. gymnogyra (Morch, 1874)

Furthermore Mørch described as ‘var.? C. gymnospira’^(*) another form from Sylt with a shell height of 50 mm, differing by ‘t. latiore spira breviore, anfr. infra carinam obsoletissime undulatis, C. derelictus non absimilis’ (= ~ having a broader shell and shorter spire, the whorl part below the carina very slightly undulating, not unlike C. derelictus’) ⁽¹⁾.
