	Sedimentologic and palaeontological investigation of the Upper Pliocene Slama Formation in the Lower Chelif Basin (NW Algeria) led us to collect important bivalve assemblages for taxonomic and taphonomic purposes. A rather comprehensive inventory list of Upper Pliocene bivalves from northwestern Algeria is now available and consists of 30 species, 17 of which are extinct ones. Four principal taphonomic attributes were analysed: bioerosion, encrustation, fragmentation, and abrasion. Physical and biogenic sedimentary structures are used for palaeoenvironmental interpretations. The taphonomic, sedimentologic and ichnological characteristics of most of the deposits suggests they originated from discontinuous processes of winnowing and bypassing of sediments, probably due to the action of storms in shallow waters, mainly in the shoreface depositional environment. The bivalve assemblage is dominated by disarticulated valves and displays significant taphonomic alteration in the shells. Sclerobionts traces in shells particulary affect the oyster shells. Bioerosion traces are predominately those of clionid sponges (&lt;em&gt;Entobia&lt;/em&gt;&amp;nbsp;isp.), polychaetes (&lt;em&gt;Maeandropolydora&lt;/em&gt;&amp;nbsp;isp. and&amp;nbsp;&lt;em&gt;Caulostrepsis&lt;/em&gt;&amp;nbsp;isp.), bivalves (&lt;em&gt;Gastrochaenolites&lt;/em&gt;&amp;nbsp;isp.), and of predatory gastropods (&lt;em&gt;Oichnus&lt;/em&gt;&amp;nbsp;isp.). Among the sclerobionts, the identified encrusters were juvenile oyster recruits, barnacles, polychaetes (serpulid tubeworms), bryozoans (&lt;em&gt;Microporella&lt;/em&gt;&amp;nbsp;sp. and&amp;nbsp;&lt;em&gt;Acanthodesia&lt;/em&gt;&amp;nbsp;sp.), and vermetid gastropods (&lt;em&gt;Petaloconchus intortus&lt;/em&gt;).
