Resumen: The irregular echinoid Clypeaster Lamarck is locally common in Oligocene to Quaternay sedimentary deposits in the Caribbean region, particulary in marine limestones of shallow-water origin. Clypeaster lamprus H.L. Clark is the first member of this genus identified from the deeper water shelf limestones of the early Pleistocene Manchioneal Formation of Jamaica.
Resumen: Although still extant in the tropical western Atlantic and Caribbean, this species is unknown from the Recent of Jamaica. Extant C. lampru is a deeper water species (79-450 m), with a depth range comparable with that otherwise estimated for the Manchioneal Formation.
Resumen: This genus is common in the Oligo-Miocene shelf limestones of the White Limestone Group, but is rarer in the :overlaying carbonate and silliciclastic facies of the Coastal Group (Upper Miocene to Pleistocene). A preliminary Clypeaster biostratigraphy is presented for Jamaica.
