Analysis of the molluscan fauna of Tyrrhenian shorelines in Tunisia allows their depositional environment, and thus the position of the contemporaneous sea level, to be accurately determined. Faunal analysis and radiometric dating of the shorelines reveal that differences in depositional environment have been mistaken for differences in age. Apparently different Tyrrhenian shorelines are the product of a single marine transgression. Preliminary 14C dates on molluscs from 4 sites suggest that the transgression occurred about 30 000yr ago. The resulting shoreline has been uplifted and subjected to post-depositional deformation. The general rate of uplift exceeds 1mm/yr, and in areas of active faulting and folding the uplift may reach 3mm/yr.-from Author
