| Summary: | Cretadmete sp. (Fig. 8A–C) 2015 Maturifusidae? gen. et sp. indet.; Hryniewicz et al. 2015a, table 1. Description. Protoconch not preserved. Shell small, 4.5 mm in height and 5.3 mm in width, fusiform/turbiniform with two strongly convex whorls preserved. Suture moderately incised. Shell flank ornamented with numerous spiral cords arranged in two orders; each two 1 st order cords sandwich one weaker 2nd order cord. The spiral ornament is crossed by prosocline axial ridges with no clear knobs and the intersections, which, however, might be slightly undulating in the adapical portion of flank. Transition between flank and base without angulation, but distinct due to disappearance of axial ornamentation and 2nd order spiral cords. Aperture poorly preserved with no apertural elaborations visible. Anterior part of the aperture broken off. No umbilicus. Material and occurrence: One specimen (PMO 224.762) from seep deposit #8, Sassenfjorden, Svalbard; Late Tithonian, Late Jurassic. Remarks. This juvenile shell is ... : Published as part of Nakrem, Hans Arne, 2017, Gastropods from the Late Jurassic - Early Cretaceous seep deposits in Spitsbergen, Svalbard, pp. 351-374 in Zootaxa 4329 (4) on page 363, DOI: 10.11646/zootaxa.4329.4.3, http://zenodo.org/record/1003014 ... |
