Clypeaster lamprus H.L.Clark (Echinodermata: Echinoidea) in the Manchioneal Formation (early Pleistocene) of Jamaica.
Caribbean Journal of Science
Date of Publication
The irregular echinoid Clypeaster Lamarck is common locally in Oligocene to Quaternary sedimentary deposits in the Caribbean region, particularly 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 limestone of the early Pleistocene Manchioneal Formation of Jamaica. This species is unknown from the Recent of Jamaica although still extant in the tropical western Atlantic and Caribbean. Extant C. lamprus is a deeper water species with a depth range comparable with that otherwise estimated for the Manchioneal Formation. This genus is common in the Oligo-Miocene shelf limestones of the White Limestone Group, but it is rarer in the overlying carbonate and siliciclastic facies of the Coastal Group (Upper Miocene to Pleistocene). A preliminary Clypeaster biostratigraphy is presented for Jamaica.....
