Indeed, the stratigraphic section of the lower Pliocene of Azaizia ,offers a succession of markers ranging from Sphaeroidinellopsis, Globorotalia margaritae, Gl. Puncticulata, Globorotalia crassaformis indicating the base of the Pliocene (Zanclean , The nannofossils reveal the presence of "Ceratolithus acutus (B 5.36 Ma, T 5.04 Ma)" from the extreme base of the Pliocene (Zancléen), Amaurolitus primus (T 4.58 Ma) "and" Reticulofenestra pseudoumbilicus (T 3.7 Ma) » These data are exceptional, because of the presence, for the first time, of the extreme base of Zanclean in the Chélif basin and in the Dahra massif.
