Conger ? vetustus Frizzell & Lamber, 1962: 100 , figs 6a–b, 8a–d.

Conger vetustus – Nolf 1985: 42; 2013: 35, pl. 22. — Nolf & Stringer 2003: pl. 1 fig. 9.

Remarks

A single otolith of this species was collected from the “upper” Lisbon Formation (Alabama) ( Table 1 ). Despite its poor preservation, the characteristically very elongate otolith shape and the straight but obliquely ventrally oriented sulcus allow a conclusive identification.

Stratigraphic and geographic distribution

Bartonian: Moodys Branch Formation, Louisiana and Mississippi; “upper” Lisbon Formation, Alabama. Priabonian: Yazoo Clay, Louisiana.
