The earliest blade industries in North Africa belong to the Iberomaurusian or Oranian (after a site near Oran). This lithic industry appears to have spread throughout the coastal regions of North Africa between 15,000 and 10,000 BC. Between about 9000 and 5000 BC, the Capsian culture made its appearance showing signs to belong to the Neolithic and began influencing the Iberomaurusian, and after about 3000 BC the remains of just one human culture can be found throughout the former region. Neolithic society (marked by animal domestication and subsistence agriculture) spread in the Saharan and Mediterranean North Africa after the Levant between 6000 and 2000 BC. This type of economy, so richly depicted in the Tassili n'Ajjer cave paintings, predominated in North Africa until the classical period.
