Abstract
An exceptionally thick deposit of gastropod shells (mainly pteropods and heteropods) has been found in a core sampled in a distributive channel of the Rhône deep-sea fan. Radiocarbon dating, as well as the zoogeographic and climatic distribution of the fauna, show that this layer has been deposited during the Holocene period whereas the underlying muddy sediment is of Würmian age. This change of sedimentation can be related to a strengthening of the bottom currents in the Rhône deep sea fan (especially in its distributive channels) since the end of the glacial times. From a more general point of view, this could to a certain extent be related to the important changes that occurred in the Mediterranean Sea since this epoch.
