Material examined

UNITED STATES OF AMERICA – Alabama • 5 otoliths; GLS otolith comparative collection (4 specimens), MSC 39063 .

Description

Sulcus distinctly divided, clearly heterosulcoid. Wide ostium, much narrower cauda. Cauda is uniform in width, downturned ventrally. Ostium tends to widen ventrally.

Remarks

The five specimens exhibit features of percoids (Suborder Percoidei, Order Perciformes ). Perciform otoliths are usually distinctly heterosulcoid, with an ostium that widens ventrally and a much narrower cauda that is usually uniform in its width and bent ventrally. Unfortunately, the specimens could not be identified to a specific perciform family.

Stratigraphic and geographic range in Alabama

All of the specimens assigned to Percoidei indet. 1 were recovered from the “upper” Lisbon Formation at site ACh-8. Bartonian, zones NP16 and NP17.
