Sobre la presencia de un Sciaenidae (Teleostei: Perciformes) en el “Belgranense” (= Fm. Pascua, Pleistoceno superior) de Centinela del Mar, Buenos Aires (Argentina)

Abstract

The objective of the present communication is to report the presence of an otolith (sagitta) referable to a whitemouth croaker, Micropogonias furnieri. This material proceeds from estuarine strata corresponding to the marine transgression “Belgranense” (Upper Pleistocene) of the locality of Centinela del Mar, province of Buenos Aires, Argentina. The otolith has a prominent protuberance at the external tip, character that nowadays is related to the southernmost population of the species to which was referred. The material presented here constitutes the only otolith of Micropogonias furnieri known for the Pleistocene of Argentina and also one of the scarce records for the Neogene of South America.
