Material. 1 specimen, PIMUZ A/I 5065, Pebas Fm., middle Miocene, Iquitos (layer I), Peru .

Discussion. A single, relatively small otolith of 3 mm in length could possibly represent a juvenile specimen of Sciaenops , but, in light of the habitat of the extant S. ocellatus in coastal marine environments of the tropical and subtropical western Atlantic, we assign the specimen only tentatively. Te relatively small ostium, thin appearance, and wide ostial–caudal interspace resemble S. ocellatus otoliths but differs in the tip of the cauda being bent slightly forward (vs. vertical, not bent forward).
