) is the setting of a complex of caves near the village of Montignac, in the department of Dordogne in southwestern France.Over 600 parietal wall paintings cover the interior walls and ceilings of the cave.In May 2012 Ochroconis lascauxensis, a species of fungus of the Ascomycota phylum, was officially described and named after the place of its first emergence and isolation, the Lascaux cave.This followed on from the discovery of another closely related species Ochroconis anomala, first observed inside the cave in 2000.
The drawings are the combined effort of many generations, and with continued debate, the age of the paintings is estimated at around 17,000 years (early Magdalenian).
In its sedimentary composition, the Vézère drainage basin covers one fourth of the département of the Dordogne, the northernmost region of the Black Périgord.
Before joining the Dordogne River near Limeuil, the Vézère flows in a south-westerly direction.
The Lascaux valley is located some distance from the major concentrations of decorated caves and inhabited sites, most of which were discovered further downstream.
In the environs of the village of Eyzies-de-Tayac Sireuil, there are no fewer than 37 decorated caves and shelters, as well as an even greater number of habitation sites from the Upper Paleolithic, located in the open, beneath a sheltering overhang, or at the entrance to one of the area's karst cavities.
Geometric images have also been found on the walls.
