Les organismes constructeurs dans les Annales de Paléontologie

Due to the variety of their systematic origins, the building organisms constitute a heterogeneous entity whose treatment in the “Annales de Paléontologie” can be appreciated according to multiple keys. The general systematic trend expressed through 100 years of history of the review is illustrated by many and rich monographic articles. The building organisms were only very rarely studied on their building capacity point of view. Thus the microbial organisms were only recently approached, with the study of the carbonated non-marine buildups, primarily resulting from the activity of cyanobacteries and algae. However various methods and approaches leaded significantly advances in the debate concerning taxonomic affinities of various building organisms as archeocyathids, stromatoporoids and chaetetids. Regarding the corals, the major contributions in the “Annales de Paléontologie” concern the methods privileging the skeletal microstructures analysis and the paleoecological considerations. Among the bivalves, the group of the rudists, which played an important role in the genesis of builded masses in Mesozoïc times, is treated under paleobiological point of view. Finally, acting of the building organisms, the “Annales de Paléontologie” reflects very well the topics of a paleontological community attached to the best possible use of effective systematic tools.
