Batrachocephalus mino (n= 1) ( Fig. 5 , Supplementary data 5)

The otolith appears to be triangular, but it has the most compact/shortest antero-distal margin among the “triangular” shaped taxa, making it seem almost like an arrowhead. Its Amp is quite prominent. It has compact curved Sl. Its Mn is compact. It has shallow ILb.
