Fig. 4.Field photographs of sample horizons of the Olenidsletta Member, Floian, Ordovician, Profilstranda section, Ny Friesland, Spitsbergen. A. Bed PO 131, 128 m above the base of the member, view of a bedding surface with several chaotically distributed fragments of orthoconic and coiled cephalopods. Note also the round shapes of individual septa from fragmented orthoconic shells. B. Bed PO 122, 119 m above the base of the member, view of a top hardground bedding surface of a limestone paracycle; the cephalopod assemblage is strongly dominated by current aligned, abundantly telescoped orthocones, and conchs are poorly preserved as steinkerns. C. Bed PO 7.5, 4.5 m above the base of the member, oblique freshly broken surface of a cephalopod coquina with current aligned, abundantly telescoped orthocones. D. Same bed in vertical view, cutting the current aligned orthocones in perpendicular direction; note the gravitational fillings, which are in original position with sparite fillings on top. : 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 page 9, DOI: 10.5852/ejt.2021.783.1601, http://zenodo.org/record/5793422
