الملخص
The Middle Jurassic (Bathonian) rocks of the Ras El Abd area include three main shell concentrations: a
molluscan shell bed, the lower rhynchonellid bed, and the upper rhynchonellid bed. Analysis of the taphonomic
signatures indicates that; the molluscan shell bed represents a proximal tempestite, the lower
rhynchonellid bed corresponds to a primary biogenic concentration sensu [Fürsich, F.T., Oschmann, W.,
1993. Shell beds as tools in basin analysis: the Jurassic of Kachchh, western India. Journal of the Geological
Society 150, 169–185], and the upper rhynchonellid bed a proximal storm-flow concentration. The
shell concentrations formed below fair-weather wave-base in shallow, relatively high energy
environments.
