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.
