Hello friends plz i want to know something about those fossils

[tmaier]

I'm guessing oysters.

Where are these from?

[safouen]

They from from South Tunisia

[tmaier]

This is a wild shot in the dark, but there is a formation in southern Tunisia called "Berda" that seems to have the same consistency of the matrix that you show in your photos. It is late Cretaceous.

Are you pretty close to Djebel Berda?

Search for "Berda Formation"

They are Rudist bivalves.

They are Rudist bivalves.

Hello, i have some old french documents that might help.

The first one "Les gisements à faune Villafranchienne de Tunisie" is about animals of late pliocene to upper pleistocene : http://horizon.documentation.ird.fr/exl-doc/pleins_textes/pleins_textes_5/b_fdi_04-05/05263.pdf

The second and third ones are about fossils of Algeria, but since Gafsa is very near and of the same formation than El Kouif in Algeria, it can be interesting for this topic. The third one is about terrestrial and river molluscs and snails : http://www.geolalg.com/bibgeolalg/livresanciens.html http://jubilotheque.upmc.fr/ead.html?id=GM_000922_001&c=GM_000922_001_e0000028&qid=sdx_q19#!{"content":["GM_000922_001_e0000028",false,"sdx_q19"]}

The fourth one "Les vertébrés fossiles des gisements de phosphates (Maroc-Algérie-Tunisie) is more for the pleasure of the lovers of shark teeth and of the chelonians : http://hybodus.free.fr/maroc/Arambourg%20%20&%20alii%20Vert%E9br%E9s%20fossiles%20des%20gisements%20de%20phosphate.pdf

Recently I came across this document. I considered it helpful, so I link it here : Albian Eoradiolites (Bivalvia: Radiolitidae) from Jabal Naïmia, Gafsa Region, Tunisia, with Revisional Studies on the Albian Forms of the Genus - Jose Maria Pons et al. http://booksc.org/book/31505058

" The lower part of the Zebbag Formation’s lower member, known as ‘‘Knemiceras beds,’’ crops out at Jabal Naı¨mia, in the eastern part of the northern range of the Chotts, Gafsa region, Tunisia (Fig. 1.1). ‘‘Knemiceras beds’’ lay unconformably above the limestones of the Aptian Orbata Formation and consist of alternating green clays and bioclastic limestones, followed upwards successively by bioclastic, micritic and dolomitic limestones, with a total thickness of nearly 70 m (Fig. 1.2); a 40 m thick dolomitic series forms a cliff on top.
Ammonites, echinoids, and ostreids, as well as other bivalves and gastropods, are frequent macrofossils throughout the section (beds 1 to 24); in the upper part of the ‘‘Knemiceras beds’’ (bed 21) a monospecific rudist bed with Eoradiolites (Fig. 1.3) occurs, which yielded the specimens used for this study.
