Many specimens of a small echinoid (sand dollar) species were collected from the excavation site of paleoparadoxiid in Kamado, Mizunami, central Japan. These are safely assigned to Kewia minoensis because of their morphology and their smallness. Occurrence of these echinoid enables to reconstruct the paleoenvironment as a purely marine environment without influence of brackish water from nearby.
