A new fossil priacanthid fish,Cookeolus spinolacrymatus, is described on the basis of a single specimen from the Late Pliocene Shinzato Formation, Shimajiri Group, Miyagi-shima, Okinawa, Japan. This species is distinguished from the Recent speciesC. japonicus (Cuvier, 1828) by having a strong spine on the anterior portion of the lacrymal. The specimen was identified as a small benthic adult, or large juvenile, based on comparison with pelvic fin length development in the Recent species.
