The Eocene of Egypt comprises shallow-marine and marginal Sediments that were deposited in narrow and elongated tectonic basins forming embayments of the Tethys. Early and Middle Eocene were times of carbonate Sedimentation, but due to regression, Sediments became essentially terrigenous from the Late Eocene onwards. Compilations on stratigraphy and Sedimentation patterns are provided by SAID (1962) and SALEM (1976). The object of this paper is to apply the concept of "event-stratification" to two rather different kinds of shell deposits: 1. Accumulations of nummulites as a very special case of bioclastics. 2. Several prominent and laterally persistent shell beds, that are being used for refined stratigraphic correlation (STROUGO 1977).
