In 15.83-10.71 Ma, floral distributions clearly show the existence of the Circum-tropical Current between the Caribbean and the eastern equatorial Pacific and no surface water communication between the northern and southern Caribbean. In 10.71-9.36 Ma, the Circum-tropical Current weakened and the northward intra-Caribbean current had been initiated. Northern and southern Caribbean surface waters again became separated in 8.35-3.65 Ma and the Circum-tropical Current was regenerated. After 2.76 Ma, the northward intra-Caribbean current has completely been established and the Circum-tropical Current disappeared. This suggests that a barrier to the Circum-tropical Current had formed, indicating the final closure of the Isthmus of Panama.","descriptionType":"Abstract"},{"description":"Supplement to: Kameo, Koji; Sato, Tokiyuki (2000): Biogeography of Neogene calcareous nannofossils in the Caribbean and the eastern equatorial Pacific - floral response to the emergence of the Isthmus of Panama.
