Preophidion arcuatus ( Stinton, 1966)

Fig. 9A–C

Otoliths belonging to this species are commonly found in the Bashi and Hatchetigbee formations and share several distinctive characteristics with those of P. arcuatus from the Ypresian London Clay, as described by Stinton (1966) under the name Brotula arcuatus . The general outline of the otoliths, as well as the downward-bent cauda, suggest that this species can be assigned to the fossil genus Preophidion .
