Description
Summary:Cepola anderssoni sp. nov. (Figs 5Q, R, 6R) Material. Holotype: NRM-PZ P.15996 (Figs 5Q, R, 6R) (only specimen, broken into two halves during handling). Occurrence. Telm 5 unit; ‘ Natica horizon’, Cucullea I member, La Meseta Formation, late Ypresian, early Eocene. Site IAA 2/95, Seymour Island, Antarctica. Etymology. Named in honour of Johan Gunnar Andersson, a Swedish pioneer of geological research in Antarctica. Diagnosis. OL:OH = 1.85. Dorsal rim shallow, with broadly rounded postdorsal angle. Rostrum sharp; posterior tip less sharp. OsL:CaL = 2.1; OCL: CCL = 2.0. Ostial colliculum reduced anteriorly, terminating at considerable distance from anterior rim of otolith. Outer face flat. Description. Otolith elongate, thin, 4.4 mm long. OH:OT = 3.2. Dorsal rim shallow, gently curving, smooth, with broadly rounded postdorsal angle and highest at postdorsal angle. Ventral shallow, very regularly curving, highest at its middle, smooth. Rostrum long and sharp; dorsal margin of ostial opening regularly ascending ... : Published as part of Schwarzhans, Werner, Mors, Thomas, Engelbrecht, Andrea, Reguero, Marcelo & Kriwet, Jurgen, 2017, Before the freeze: otoliths from the Eocene of Seymour Island, Antarctica, reveal dominance of gadiform fishes (Teleostei), pp. 147-170 in Journal of Systematic Palaeontology 15 (2) on pages 160-162, DOI: 10.1080/14772019.2016.1151958, http://zenodo.org/record/10883098 ...
