Description
Summary:Notoberyx cionei sp. nov. (Figs 5D—G, 6O) Material. Holotype: NRM-PZ P.15987 (Figs 5D—F, 6O). Paratypes: two specimens, NRM-PZ P.15988— 15989 (Fig. 5G). 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 Alberto Cione (La Plata, Argentina) for his many contributions to the knowledge of fossil fishes from South America and Antarctica. Diagnosis. OL:OH = 0.7—0.75. Dorsal rim high, broad; ventral rim deep, broad. Rostrum short, blunt, about equal length of antirostrum. CaL:OsL = 1.4—1.5. Ostium narrow, only slightly wider than cauda; cauda distinctly turned upwards. Description. Large, robust, high-bodied, oval otoliths up to about 6 mm in length (holotype 5.8 mm long). OL:OT = 3.0. Dorsal rim high, much expanded and broad, undulating; rounded pre- and postdorsal angles close to anterior and posterior limits of dorsal rim, postdorsal angle usually somewhat pronounced.
