A massive, thick otolith is referred to the genus Xenomystax Gilbert, 1891 ( Fig. 2C ). The specimen is elliptic and elongate with nearly smooth margins. It is characterised by a rather pointed and extended anterior end and a rounded and robust posterior part. A well-marked and deep dorsal depression on the high dorsal area is observed. The sulcus is wide, oval and situated at the center of the otolith. Otoliths of three Recent species of Xenomystax are illustrated ( Fig. 3 A–D, M–O) for comparison. The fossil specimen is most similar to that of X. congroides Smith & Kanazawa, 1989 ( Fig. 3 M–N), a western Atlantic species, but differs in showing a shallower and more elongate outline and a more extended anterior part.
