Description The specimen is a fragment of a slightly crushed 30 mm long portion of a body chamber with the last septum preserved. The conch is smooth, straight and slender and has an elliptically depressed cross section with a height of 18 mm and a width of 22 mm (rW = 1.22). The preserved septum forms a suture that is slightly oblique across the flanks of the conch shifted toward the aperture at the antisiphuncular side of the conch; it forms shallow lateral saddles, is almost transverse dorsally, and forms a deep, broad u-shaped ventral lobe. The siphuncle is marginally positioned and elliptically depressed with a septal perforation 8 mm in height and 9 mm in width (rSD = 0.4). No details of the septal necks or the connecting ring are preserved. Remarks The specimen is assigned to Cyptendoceras because of the presence of the characteristic u-shaped ventral lobe. However, neither the septal spacing, nor the details of the septal necks and connecting ring are known, which precludes a species level determination of the specimen. : Published as part of Kröger, Björn & Pohle, Alexander, 2021, Early-Middle Ordovician cephalopods from Ny Friesland, Spitsbergen - a pelagic fauna with Laurentian affinities, pp. 1-102 in European Journal of Taxonomy 783 (1) on pages 44-45, DOI: 10.5852/ejt.2021.783.1601, http://zenodo.org/record/5793422 Text Ny Friesland Spitsbergen DataCite Metadata Store (German National Library of Science and Technology) Hinlopenstretet ENVELOPE(20.728,20.728,79.246,79.246) Ny Friesland ENVELOPE(16.847,16.847,79.498,79.498) |
