The nautiloid Aturia (Mollusca, Cephalopoda) in the Mid-Cainozoic of Jamaica and Carriacou

Recent collections in Jamaica and Carriacou have yielded new specimens of the nautiloid Aturia, a rare fossil in the Antilles. Hitherto, many of these specimens have not been described or illustrated and those derived from the Middle Miocene Grand Bay Formation of Carriacou represent the youngest nautiloids now known from the Caribbean. Additionally, stratigraphic nomenclature provided for some previously reported Jamaica and Carriacou Aturia is herein revised to better place these very uncommon fossils in their proper lithostratigraphic context.
