Les gisements de mammifères aquitaniens de La Chaux (Jura vaudois, Suisse)

After a short description of the topography and geology of the famous vertebrate locality of La Chaux, a historical survey of the different excavations and palaeontological studies based on unpublished documents is given. The detailed description of the layers with their very diverse fossil content is founded on observations we could make during the extensive road works in 1994. These observations permit the reconstruction of the sedimentation conditions and of the palaeo-ecological circumstances. The precise datation of the fossiliferous layers is based on the analysis of the small mammal teeth. A detailed study of this material of several thousand isolated teeth will be published separately.
