Ariosoma sp.

Fig. 4A

A single Ariosoma otolith was recovered from the Bashi Formation, Mississippi ( Table 1 ). The otolith differs from the common species of Ariosoma , A. nonsector Nolf & Stringer, 2003 , by having a flatter dorsal rim, but we retain our identification due to the lack of sufficient specimens.
