(Fig. 5H)
Material. A single, strongly eroded specimen, NRM-PZ P.15986.
Occurrence. Site IAA 1/90, La Meseta Formation, Seymour Island, Antarctica.
Remarks. Despite its very poor preservation expressed in relief reversal of the otolith rims, this otolith is readily recognizable as a representative of the genus Centroberyx by its outline in combination with the very large and wide rostrum and the short, somewhat upward trending cauda. Centroberyx otoliths are common in the Late Cretaceous and Palaeogene of many locations (Nolf 2013).
