Twyfelfontein has one of the largest concentrations of rock engravings in Africa. Most of these well preserved works include rhinos, elephants, ostriches and giraffes, as well as footprints of both humans and animals. The property also includes six rock shelters decorated with human representations painted in red ochre. The remains found in two parts of the site have been dated back to the late Stone Age. The site forms a coherent, large-scale and quality ensemble that reflects the ritual practices of hunter-gatherer communities in this part of southern Africa over the last two millennia; it eloquently illustrates the links between the ritual and economic practices of hunter-gatherers.
NAMIB SAND SEA
Namib Sand Sea is the only coastal desert in the world that includes extensive dune fields influenced by fog. Covering an area of over three million hectares and a buffer zone of 899,500 hectares, the site is composed of two dune systems, an ancient semi-consolidated one overlain by a younger active one. The desert dunes are formed by the transportation of materials thousands of kilometres from the hinterland, that are carried by river, ocean current and wind. It features gravel plains, coastal flats, rocky hills, inselbergs within the sand sea, a coastal lagoon and ephemeral rivers, resulting in a landscape of exceptional beauty. Fog is the primary source of water in the site, accounting for a unique environment in which endemic invertebrates, reptiles and mammals adapt to an ever-changing variety of microhabitats and ecological niches.
