Abstract
Seventy rudist taxa from the Algerian Cretaceous (Neocomian to Maastrichtian) are listed. Rudists are particularly diverse during the Late Aptian and the Late Cenomanian periods and thus useful to identify and/or to correlate the rocks of these ages. Comments are made on their geographic and stratigraphic distribution in order to explain the reason for their abundance or absence and to guide future prospecting. The Constantinois platform seems to be the best area for rudist platform study, as it has been a high domain, sheltered from siliciclastic sedimentation, from the Neocomian to the Turonian. Algerian palaeogeography, during the Late Cretaceous, was globally unfavourable for rudist development, but some rudist levels appear where local topography facilitated their development.
