Numerous specimens from several trackbearing surfaces within the marl units. These geological formations consist of layers several kilometres thick and mainly include sandstones, calcareous sandstone and marls. This contrasts with the absence of marl and charcoal, as well as the non-oily texture, in the midden above the flagstones. The marl layer represents the clean bedrock base beneath the structure. Boulders of fault-derived breccias covered by marl layers were found close to the thrust, suggesting that the hanging-wall uplift took place during sedimentation. The middle member comprises ochre-brown marls and grey or grey-brown limestone beds which are sometimes marly and more often microsparitic. The midden below the pavement was very moist and oily, with a tremendous quantity of small charcoal fragments and marl inclusions. These are in growth position, low to highly dome-shaped, and are draped by overlying marls. The intercalated marls are thinner and contain similar coarse bioclastic material. Tracks occur throughout the marls, and five representative track-bearing surfaces were excavated. At the locality studied the marl is well laminated and contains millimetre-scale coarser (fine sand-silt) laminae. These examples are from corpora and from sources on the web.
