This monograph of a rich fossil fauna of the Paris basin gives account of a mid-Thanetian locality. The facies changes within two quarries allow to subdivide the Châlons-sur-Vesle Formation into several subunits. Bathymetry and distance to the shore of the infralittoral sands are deduced from sediment analyses and fossil assemblage interpretations. Variations in the mixture of subautochtonous and displaced molluscs, and of infralittoral marine biotopes, shorelines and continental subenvironments suggest a transgressive-regressive local evolution. Several topics are studied in greater detail: the deformation structures on the lower sand, interpreted as seismites; the stratigraphic distribution of the foraminifera and their environmental significance; the regional interpretation of fish biodiversity (sharks, rays and teleosteans); the four main steps in changes of the molluscs assemblages, by means of specimen counting per species. Of special interest is the oyster's paleoecology (attachment on Dasycladaceae and sea-grass) and the boring predation-marks by Naticidae and Muricidae on molluscs, and their use in the reconstruction of different life-environmentsof the assemblage's components. An atlas of 33 plates shows the different facies of sand subunits, from the quarry to cleaned horizontal samples of shell accumulations, and a very complete iconography, especially of vertebrates and molluscs, of the taxa collected at Cauroy-lès-Hermonville and Prouilly (Marne). The plate captions of molluscs include systematics and ecological comments, with reference to the present distribution of related species. The palaeoenvironmental and climatic interpretations of this fossil assemblage, representative of the inner Parisian gulf of the mid-Paleocene (Middle Thanetian), are founded on the reconstruction of different shallow-water, marine sea beds, more or less influenced by subtropical sea-grass and Dasycladacean algae discontinuous cover and storm hydrodynamics. 119 pp., 22 figs, 33 pls, br. 4.
