land-locked configuration of the Mediterranean region has appeared to be
extremely sensitive to record changes in paleoclimate and paleoenvironment
and integrated stratigraphic studies have revealed that the sedimentary
record accurately reflects astronomically induced changes in solar insolation.
This has allowed the construction of very detailed astronomically tuned
geological polarity time scales, which at present underlie most modern
paleoclimatic, paleoceanographic and paleogeobiologic research efforts.
In contrast, the time
scale for the Paratethys domain is highly equivocal and controversial ages
exist for many events and geological stage boundaries.
The small marine opening
through the Bosporus did not exist during large parts of the Neogene. The
key question that hampers a full understanding of the paleoclimatological
evolution of Eurasia during that time period thus relates to the closure
and opening of the marine connection(s) between Mediterranean and Paratethys,
and is at present far from understood.
