Abri des Fieux was excavated by Chauvet in 1897 who found five layers which found a lithic industry and a harpoon in polished bone, then by Boudineau the mayor of Edon in 1929. The excavations were resumed by Roche in 1951 who found in the upper layer 57 Mesolithic tools attributable to the Tardenoisien. The next layer delivered 124 tools of the Sauveterrien (so between the Tardenoisien and the Magdalenian). And the bottom layer contained 303 Magdalenian tools.

The fauna found signs of a period of temperate climate with the presence of deer and beaver.
