| Summary: | Hoplobrotula ? antipoda sp. nov. (Figs 5A—C, 6O, P) Material. Holotype: NRM-PZ P.15984 (Figs 5A, B, 6O, P). Paratype: NRM-PZ P.15985 (Fig. 5C). Occurrence. Telm 5 unit; ‘ Natica horizon’, Cucullea I member, La Meseta Formation, late Ypresian, early Eocene. Site IAA 1/90, Seymour Island, Antarctica. Etymology. Named for its occurrence on the opposite side of the globe when compared to other Eocene species of the genus, known from Europe. Diagnosis. OL:OH = 1.75—1.95. Dorsal rim with low, broad predorsal lobe. OCL: CCL = 2.5—2.75. Sulcus and particularly ostium very narrow. Description. Relatively small, elongate and thin otoliths up to 4 mm in length (holotype 3.9 mm long). OH:OT = 2.6. Dorsal rim rather regularly and gently curved with broad, not much expanded predorsal lobe. Ventral rim regularly curved, deepest slightly in front of its middle. Anterior tip tapering, inferior, below level of ostium; posterior tip narrow, tapering, at level of cauda. All rims smooth. Inner face moderately convex, smooth, ... : 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 page 158, DOI: 10.1080/14772019.2016.1151958, http://zenodo.org/record/10883098 ... |
