Paleocene spatangoids are unknown from the Antilles, apart from evidence from trace fossils. The peak of spatangoid diversity was the Eocene. Jamaican Oligo-Miocene spatangoids have a relatively low diversity compared with that of the Antillean region. Plio-Pleistocene spatangoids are poorly known from the Antilles (four genera), in contrast to the Oligo-Miocene (16 genera) and Holocene (17 genera). The depauperate Paleocene and Plio-Pleistocene spatangoid faunas are probably in part artifacts of incomplete sampling, facies-related absences, outcrop area effects and the relative brevity of these stratigraphic intervals. To the large echinoid fauna of the Swanswick Formation (Middle-Upper Eocene) of Jamaica is added the schizasterid Aguayoaster schickleri new species. This is the first record of this genus outside Cuba; it is distinctly more elongate than all other known specimens of this genus. The schizasterid Caribbaster loveni (Cotteau, 1875) is recorded from the Swanswick ormation
