| During the Secondary and Tertiary periods, the northern continental margin of the Bay of Biscay was the scene of some subsidence phenomena which lowered the continental blocks through faults. This was mainly observed off the coast of Brittany and at the entrance of the English Channel [(2), (3)]. During the Géogas cruise of the research vessel "Jean-Charcot" (October 1972), samples were taken from the Mériadzek scarp which forms one of these blocks. A dredging conducted on the southern limb of this structure (pl.) enabled the sampling of some sedimentary rocks among which some fragments of a yellow limestone containing a fauna of rudists could be found. |

| The presence in Lebanon of Offneria murgensis and Offneria nicolinae, two characteristic components of the Early Aptian Arabo-African rudist faunas, fills a distributional gap of the corresponding assemblage between the Arabic and African occurrences, on the one hand, and the Apulian occurrences, on the other hand. This fauna bears out the palaeogeographic placement of Lebanon on the southern Mediterranean Tethys margin established by palaeostructural reconstructions. The associated micropaleontological elements suggest an earliest Aptian age (early Bedoulian) for the Offneria murgensis - O. nicolinae assemblage found in the "Falaise de BLANCHE" stratigraphic interval, instead of a late Early Aptian age as proposed for most of the peri-Adriatic and Middle... |
