The Azilian is a Mesolithic industry of the Franco-Cantabrian region of northern Spain and Southern France. It dates approximately 10,000–12,500 years ago. Diagnostic artifacts from the culture include projectile points (microliths with rounded retouched backs), crude flat bone harpoons and pebbles with abstract decoration. The latter were first found in the River Arize at the type-site for the culture, the ''Grotte du Mas d'Azil'' at Le Mas-d'Azil in the French Pyrenees (illustrated, now with a modern road running through it). These are the main type of Azilian art, showing a great reduction
