The Ammonite cave is located in the commune of Vilhonneur, Charente, 30 km east of Angoulême, 500 meters from the Grotte du Placard.

The cave was named in 1934 by Ragout, who, by carrying out a first survey, found a small ammonite.

His excavation showed the presence of two levels dating from the Upper Paleolithic, in particular the Magdalenian.

The lower layer more than one meter thick, delivered hundreds of lithic objects, simple lamellae, arched back lamellae, chisels, drills, and scrapers.

The bone tools found are spear fragments, harpoons, hooks, punches, needles, rings, and ornate bone fragments.
