A Mustahil section, measured at Bur Bitthale near Belet Uen (Central Somalia), is here described.

Abstract
A Mustahil section, measured at Bur Bitthale near Belet Uen (Central Somalia), is here described. The succession, dated as Late Aptian to Early-Middle Albian age on the basis of good faunal evidence consists of two well developed thickening-coarsening sequences, where four different facies have been recognized. The cap of both sequences is represented by a rudistid framework dominated by Eoradiolites lyratus. We interpret these cycles as shoaling up parasequences, which are the result of two depositional regressions produced by the progradation of broad shallow-water carbonate systems over the adjacent ramp and deep shelf. -from Authors
