Article: Fossil microplankton in deep-sea cores from the Caribbean Sea

Quaternary fossil microplankton is described from three piston cores taken in the Caribbean Sea. Two cores were from the abyssal plain of the Yucatan Basin in the western Caribbean and the third from the Cariaco Trench, a deep-water depression lying within the continental shelf off Venezuela. This microplankton includes five new genera and eighteen new or reclassified species of dinoflagellates. Its stratigraphic distribution is outlined and its origin and ecology is discussed.
