The faunal composition of Upper Pleistocene-Holocene sedimentary sections was investigated from several boreholes in the coastal areas of the northern and eastern Marmara Sea. The boreholes penetrated to pre-Quaternary basement and contain sediments deposited in near-shore environments, such as lagoons, estuaries and deltas. During the post-glacial transgression, rapidly rising sea level drowned these littoral areas, progressively transforming into their present form over the last 9.5-10 ka BP (uncalib.). Thus the lower Kucukcekmece valley became a lagoon, while the Golden Horn became an estuary. On the northeast coast, the Kurbagali delta was submerged. When the rate of sea level rise decreased at about 5000-6000 years ago, the influence of Mediterranean water on the faunal assemblage was surpassed by salinity tolerant forms, probably due to increased freshwater and sediment input on land.
