Abstract
    Based on all available ages obtained on the dominant framework building scleractinian coldwater coral species Lophelia pertusa and Madrepora oculata collected in the entire Mediterranean Sea (compiled from literature review and own studies), we discuss the basin-wide occurrences of these species emphasising their spatial and temporal development during the late glacial and Holocene. We show that these species became abundant since the deglacial (<14ka) and their Late Pleistocene and Holocene proliferation or demise significantly differed between the eastern and western Mediterranean Sea sub-basins, depending on regional (sub-basin related) environmental conditions, like the availability of food or bottom water oxygenation. In combination with the corals' preference to settle in intermediate depths, a strong relationship between Mediterranean cold-water coral development and intermediate water mass circulation is suggested, though resulting regionally in different parameters influencing the corals’ prosperity.
