Towards the end of this period, up till the first centuries AD, societies continued to grow and become more complex, with regional differentiation in agricultural and funerary practices. A notable culture of this late period is the Bura culture (circa 200–1300 AD), named for the Bura archaeological site. where a burial replete with many iron and ceramic statuettes were discovered. The Neolithic era also saw the flourishing of Saharan rock art, most notably in the Aïr Mountains, Termit Massif, Djado Plateau, Iwelene, Arakao, Tamakon, Tzerzait, Iferouane, Mammanet and Dabous; the art spans the period from 10,000BC to 100AD and depicts a range of subjects, from the varied fauna of the landscape to depictions of spear-carrying figures dubbed 'Libyan warriors'.
