The SedimentBy studying sediments, we can learn about the origin of the material, the conditions of its transport and the characteristics of its environment of deposition. Observations can be made at different levels:

Sedimentary EnvironmentsIn the reconstruction of ancient sedimentary environments, one uses information gathered both from fossils and from the sediment itself. From this one can visualise the infinite variety of environments which have occurred during the long history of the Earth. One can group these environments into a limited number of categories.

The Ediacara FaunaAlthough it occurs outside Europe, the Ediacara fauna will be described here because it represents a fundamental stage in the history of life. As far as we know at present, it is the oldest example of a biotope.

The Shores of the Auversian SeaAt the beginning of the late Eocene, in . or . . times, a marine transgression flooded the Paris Basin from the west. It formed a gulf which reached as far as Champagne to the east and which was separated from the Belgian basin by the Artois ridge. This sea was surrounded by a complex of lakes and lagoons (Fig. 124).

Fossil hunters find them very attractive, and for the geologist they are an unequalled source of information on ancient environments and can give great assistance in interpreting deposits of the same age which are less rich in fossils.
