Abstract

A new species of early Miocene croaker of the genus Pogonias (Perciformes: Sciaenidae) from the marine upper Olcese Sand, southeastern San Joaquin Valley, Kern County, California is described based on saccular (5sagittae) otoliths. This is the first fossil record of the genus Pogonias from the eastern Pacific Rim. It is hypothesized that this new species of Pogonias or its ancestor emigrated from the Gulf Stream of the western Atlantic into the eastern Pacific via the Panama seaway during or prior to the late early Miocene.
