Bivalves (Mollusca) of the Neogene of L'Oranie (North-West of Algeria)

Bivalves of the Neogene deposits of the North West of Algeria constitute a useful Tool to understand the ancient environments. In fact, we did find them in almost all mio-pliocene facies of the three important basins of l'Oranie (Bas Chelif basin, Tafna basin & M'sirda basin).They showed significant diversity and shells are often highly well preserved. Pecinidae is the most abundant family in all studied sites.
