Where is Pech IV and how old is it?
Pech de l’Azé IV is an archaeological site in the Périgord region of southern France. It dates to the time of the Neandertals and contains occupational debris from many millennia of Neandertal intermittent use of the cave. This sequence of occupation begins perhaps about 80,000 to 90,000 years ago, and ends about 35,000 years ago.
