Geology comments: From Ref. 7488: "The Rabat-Tiflet area is a complex "anticlinal resp. anticlinorial" structure (W-E). The beds are folded in a mediotype style and disturbed by normal faults and several overthrusts of limited extent. Traces of isoclinal folding are rare. The folding is the result of the Hercynian (Variscan) orogeny. The R-T area is a typical region of the so-called Hercynian-Bohemian facies development of the Silurian and Devonian, moreover in facies and faunal development very reminiscent of the barrandian area...It is characterized by a complete marine succession, a conformable gradual transition from the Upper Silurian (Budnanian) into the early Lower Devonian (Lochkovian), without any effects of the Late Caledonian orogeny."
Taphonomy
Collection methods and comments
Collection excludes:some macrofossils
Reason for describing collection:taxonomic analysis
Taxonomic list comments:Faunas of the R-T area include graptolites, tentaculitids, conodonts, and brachiopods. The last two groups have not been studied in detail.
