Description
Summary:Tripterophycis immutatus Schwarzhans, 1980 (Fig. 4A, B) 1980 Tripterophycis immutatus Schwarzhans: fig. 214. 1985 Tripterophycis immutatus Schwarzhans 1980; Schwarzhans: 22, figs 33—35. Material. One large, posteriorly eroded specimen, NRM-PZ P.15969, Site IAA 2/95, La Meseta Formation, Seymour Island, Antarctica. Description. A single, rather large otolith of about 6.7 mm in length. The specimen displays features characteristic for morid otoliths such as the thick appearance where otolith height and thickness is very similar, the flat inner face with the very peculiar sulcus with its flat, oval ostial colliculum and the ridge-like, sharp caudal colliculum sitting in a very depressed, deep cauda. The rear part of the thin, ridge-like caudal colliculum and the posterior tip of the otolith have been broken off in this particular specimen, as is often the case with morid otoliths. Remarks. The single otolith is about twice the size of the otoliths hitherto recorded from South Australia and New Zealand and ... : 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 154, DOI: 10.1080/14772019.2016.1151958, http://zenodo.org/record/10883098 ...
