Abstract
(English)
The abundance and distribution of deep-sea cold-water corals in the Mediterranean have only recently been revealed by oceanographic surveys. Living specimens are relatively rare, with Desmophyllum dianthus (solitary) and the main reef framebuilder Madrepora oculata (colonial) being the most widespread, whereas Lophelia pertusa (colonial) is known in only several locations. Although cold-water corals are now in recession, fossil examples are much more abundant, occurring throughout the Mediterranean basin either as in situ assemblages, patch reefs, or coral-bearing sedimentary mounds, at depths ranging from 250 to 3000 m. Thus, in contrast to fossil occurrences in the North Atlantic where specimens are commonly patinated by thin films of Fe–Mn, the post-last glacial maximum (LGM) occurrences on the Mediterranean continental shelves often maintain their original luster, making it difficult to discriminate between fossil and modern samples.
