Material examined UNITED STATES OF AMERICA – Alabama • 1 otolith; GLS otolith comparative collection ( 1 specimen ) . Description Singular specimen possesses characteristics of Congridae , including fairly prominent, undivided sulcus, and ostial channel. Depressed area above sulcus. Remarks The specimen could represent one of the congrids known from the Claiborne Group of Alabama , or it could represent an undescribed congrid. Unfortunately, the poor preservation limits any further study. The Lisbon Formation in Alabama preserves numerous other congrid species. Stratigraphic and geographic range in Alabama The specimen of Congridae indet. was found in the “upper” Lisbon Formation at site ACh-7. Bartonian, zones NP16 and NP17.
