The Middle Triassic succession of Tejra-Medenine site is characterized by a fauna grouped into two freshwater and one shallow-marine assemblages. Horseshoe crab recorded for the first time in the Middle Triassic of Africa. New accurate direct dating (Anisian-Ladinian) is provided for this succession and shallow-marine fauna from Tejra section was correlated with the first marine transgression of the Sahara Platform (Myophoria rich-carbonate event). The Middle-Upper Triassic major floodings and associated carbonate sedimentary events, well defined in outcrops, are used in the present work as a time lines for regional correlations with the Triassic series intersected by petroleum wells drilled in the Ghadames-Berkine basins. The age of the main Triassic sandstones reservoir producing oil and gas in the Saharan Platform (TAGI) is discussed.
