Diagnosis Slender orthocones with circular or subcircular cross section, and large subcentral siphuncles; siphuncular segments are tubular and composed of short, straight necks and thin, homogeneous connecting rings; a lamellar lining within the siphuncle thickens apically and either fills the siphuncle completely or leaves a narrow cavity dorsad of center that may be crossed by diaphragms; both hyposeptal and episeptal cameral deposits are known to develop (adopted from Hook & Flower 1977). : 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 50-51, DOI: 10.5852/ejt.2021.783.1601, http://zenodo.org/record/5793422 : {"references": ["Hook S.
