The organs of Valsenestre, in the Ecrins massif. A spectacular geological site, the Orgues de Valsenestre (or Grande Bibliothèque - Great Library) are formed of thin strata, dating from the Lias, of blue-grey limestone and softer, more eroded schistose marl, compressed and laminated and raised vertically by the Alpine orogeny - Valsenestre - Massif des Ecrins - Alpes

The Rocher de La Baume at Sisteron (Alpes-de-Haute-Provence). This remarkable structure does not correspond to a sharp anticlinal hinge, as one might think, but to the meeting of two benches, due to their bevelling by an overlapping surface. The town of Sisteron owes its strategic position to the fact that it rests on a vertical tithonic bar, which the Durance crosses via a narrow "clue" (a Provençal term equivalent to cluse*). This rocky bar forms a border between the Laragne depression to the north and the Lure mountain and Valensole basin to the south. France

Small pyrite ammonites in Aptian grey marls. The gray marls around Apt were proposed by Alcide d'Orbigny as a reference for the Aptian stage, for their rich paleontological content. Some thirty different species of ammonites have been recorded in the Tuilière sections, and belemnite rostrums are abundant in certain levels, as are gastropods and lamellibranchs (oysters and plicatula). These marls also yield corals, sea urchins, brachiopods and shark teeth. The Aptian is the penultimate stratigraphic stage of the Lower Cretaceous. It extends from ≃ -121.4 to ≃ -113.0 Ma, succeeding the Barremian and preceding the Albian (Secondary or Mesozoic Era). France

Broken fossils of rudists in a limestone rock in Biscay. Bivalve from the Secondary Era, with very uneven, rough valves, one horn-shaped and attached to the rocks, the other flat and serving as a lid. (The accumulation of rudists has formed veritable reefs ["rudist limestones"] where all the usual fauna of reef facies can be found. Basque Country, Spain
