A Mesolithic (or Epi-Palaeolithic) culture of southwest France and northern Spain, which seems to follow the Late Magdalenian of the area. It falls within the Late Glacial Period and may be correlated with the Allerod oscillation of the 10th millennium BC (c 9000 to 8000 BC). The culture was characterized by flint microliths, pebbles painted with schematic designs, small thumb-scrapers, fish hooks, and flat bone antler harpoons. It is named for Le Mas d'Zail, a massive cave region in southern France where such artifacts were first discovered in 1889. The Azilians were food gatherers who had domesticated the dog. The Oban and Oransay cultures are degenerated Azilian.
