Europe and Western Asia During the
Late Miocene (~10 Million years ago). When a good chunk of the area was
covered by a giant brackish lake known as Eastern Paratethys of which
the Black and Caspian seas are the only remnants.

Paleogeographic reconstruction of late Miocene Paratethys fluctuations.
During regressive phases, the megalake lost most of its surface. The
remaining water was split between a central salt-lake in the Black Sea
basin (marked in red) and peripheral basins that periodically refilled
and became fresher (light blue)
