Remarks Te otolith, with its distinct sulcus widening towards the caudal tip and a thick dorsal rim, suggests an affiliation with the family Trichiuridae . Specifically, it shows similarities to the otoliths of the genus Trichiurus as depicted in Lin and Chang (2012: pl. 129). However, due to the limited preservation and the lack of the anterior part of the otolith, further taxonomic assignment is not possible at this time.
