Summary:Coelorinchus balushkini sp. nov. (Figs 4S—U, 6M, N) Material. Holotype: NRM-PZ P.15976 (Figs 4S—U, 6M, N). Paratypes: two specimens, NRM-PZ P.15977. 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 in honour of A. V. Balushkin (St Petersburg, Russia) in recognition of his contribution to the knowledge of Antarctic fishes, fossil and Recent. Diagnosis. OL:OH = 1.7. Dorsal rim with marked predorsal angle. Ventral rim moderately deeply curved, deepest anteriorly, flattened at deepest point. CCL: OCL = 1.6; CaL:OsL = 1.45. Collum moderately wide, with faint pseudocolliculum. Description. Moderately compressed and moderately thin otoliths of up to at least 6 mm in length (holotype 6.0 mm long). OH:OT = 2.7. Dorsal rim highest anteriorly above ostial collum with rather sharp predorsal angle, rim somewhat undulating, posteriorly regularly declining without prominent angle. Ventral rim deep, ... : 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 157, DOI: 10.1080/14772019.2016.1151958, http://zenodo.org/record/10883098 ...
