Fifty years after it was first reported, the existence of an Echinolampas marker band in the Lower Miocene of the White Limestone Group of Jamaica remains unconfirmed. Horizons rich in monospecific accumulations of clypeasteroid echinoids (Clypeaster spp., scutelline sp. indet.) occur in these limestones and may have been misidentified by field geologists lacking expertise in echinoid systematics. This assertion is given greater credence by a recent report of related clypeasteroid taxa being similarly misidentified in the Middle Miocene of Poland.
