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 (<em>Entobia</em> isp.), polychaetes (<em>Maeandropolydora</em> isp. and <em>Caulostrepsis</em> isp.), bivalves (<em>Gastrochaenolites</em> isp.), and of predatory gastropods (<em>Oichnus</em> isp.).

This inconsistency can be explained by the ignorance of the plastronal architecture on the part of the early authors. A review of the species of <em>Pseudholaster</em> from the Cretaceous period of France was therefore carried out. The objective was to statistically determine the discriminating morphological characters, and to study the modifications of the architecture of the interambulacrum 5 of the French species belonging to this genus, as well as to the species included in the genus <em>Holaster</em> incorrectly by earlier authors. This review of the species of the genus <em>Pseudholaster</em> begins with a study of the ontogeny of the species <em>Holaster intermedius</em> Münster <em>in</em> Goldfuss, 1826–1833, first representative of the genus <em>Pseudholaster</em>, which appears in the Hauterivian in the Parisian and Rhodano-vocontian basins. The modifications during growth concern the overall shape, but also the plastron architecture: the number of plastron plates increases while the number of plates located between the peristome and the periproct remains fixed. The plastron of this species is protosternal and not meridosternal as Lambert pointed out. The labrum is cupuliform in contact with the second sternal 5a2 by a narrow digitation. However, this arrangement differs from that observed on a protosternal breastplate. This apomorphism of the plastron plate pattern, called “labrotaxienne”, is found in all the <em>Pseudholaster</em> studied, and the study of the architecture of the interambulacrum 5 also reveals a gradual decrease in the number of preanal plates between the oldest (Hauterivian) and the younger (Cenomanian-Lower Turonian) species studied. Most of the French species have been revised, with some synonyms. A new species, <em>P. neraudeaui</em>, is the last known <em>Pseudholaster</em> dated from the upper Cenomanian and lower Turonian of southwestern France. Our study illustrates the evolution of the genus <em>Pseudholaster</em> between the Hauterivian and the early Turonian in France. The interest of the study is to show that the appearance of the genus <em>Pseudholaster</em> is older than that of the genus <em>Holaster</em>. <em>Pseuholaster intermedius</em>, of Hauterivian age, possesses a derived protostern plastron called here “labrotaxien” and not meridostern as defined historically by Lambert, and to reveal that the number of preanals decreases over geological time.
