Material: 9 specimens in total. Anda1 (3) RGM 962117; Anda2 (1) RGM 962118 View Materials ; Anda4 (1) RGM 962119 View Materials ; AndaDeVos (1) RGM 962120 View Materials ; Roxas (2) RGM 962121 View Materials , RGM 962122 View Materials ; Tiep2 (1) RGM 962123 View Materials .

Nine otoliths with the typical characteristics of Polyipnus were encountered (OL:OH=0.59–0.74 for the body). Fossil specimens of Polyipnus always have lost the long, very thin rostral part. The posterior rim of the better- preserved specimen has a lobed outline, a characteristic that has disappeared in eroded specimens. Comparison of the specimens with a range of different Polyipnus species (courtesy of D. Nolf) suggested that the specimens match with P. aquavitus , which is also known form the western Pacific Ocean.
