The Aterian
Aterian
is a Middle Stone Age
Stone Age
(or Middle Palaeolithic) stone tool industry centered in North Africa, but also possibly found in Oman
Oman
and the Thar Desert.[1] The earliest Aterian
Aterian
dates to c. 145,000 years ago, at the site of Ifri n'Ammar in Morocco.[2] However, most of the early dates cluster around the beginning of the Last Interglacial, around 130,000 years ago, when the environment of North Africa
North Africa
began to ameliorate. The Aterian
Aterian
disappeared around 30,000 years ago and it is currently not thought to have influenced subsequent archaeological cultures in the region. The Aterian
Aterian
is primarily distinguished through the presence of tanged or pedunculated tools,[3] and is named after the type site of Bir el Ater, south of Tébessa.[4] Bifacially-worked, leaf-shaped tools are also a common artefact type in Aterian
Aterian
assemblages, and so are racloirs and Levallois flakes and cores. Items of personal adornment (pierced and ochred Nassarius
Nassarius
shell beads) are known from at least one Aterian
Aterian
site, with an age of 82,000 years.[5] The Aterian
Aterian
is one of the oldest examples of regional technological diversification, evidencing significant differentiation to older stone tool industries in the area, frequently described as Mousterian. The appropriateness of the term Mousterian
Mousterian
is contested in a North African context, however.

The technological character of the Aterian
Aterian
has been debated for almost a century,[3] but has until recently eluded definition. The problems defining the industry have related to its research history and the fact that a number of similarities have been observed between the Aterian
Aterian
and other North African stone tool industries of the same date.[6] Levallois reduction is widespread across the whole of North Africa throughout the Middle Stone Age, and scrapers and denticulates are ubiquitous. Bifacial foliates moreover represent a huge taxonomic category and the form and dimension of such foliates associated with tanged tools is extremely varied.[3] There is also a significant variation of tanged tools themselves, with various forms representing both different tool types (e.g., knives, scrapers, points) and the degree tool resharpening.[7] More recently, a large-scale study of North African stone tool assemblages, including Aterian
Aterian
assemblages, indicated that the traditional concept of stone tool industries is problematic in the North African Middle Stone Age. Although the term Aterian
Aterian
defines Middle Stone Age
Stone Age
assemblages from North Africa
North Africa
with tanged tools, the concept of an Aterian
Aterian
industry obfuscates other similarities between tanged tool assemblages and other non- Aterian
Aterian
North African assemblages of the same date.[8] For example, bifacial leaf points are found widely across North Africa
North Africa
in assemblages that lack tanged tools and Levallois flakes and cores are near ubiquitous. Instead of elaborating discrete industries, the findings of the comparative study suggest that North Africa
North Africa
during the Last Interglacial comprised a network of related technologies whose similarities and differences correlated with geographical distance and the palaeohydrology of a Green Sahara.[8] Assemblages with tanged tools may therefore reflect particular activities involving the use of such tool types, and may not necessarily reflect a substantively different archaeological culture to others from the same period in North Africa. The findings are significant because they suggest that current archaeological nomenclatures do not reflect the true variability of the archaeological record of North Africa
North Africa
during the Middle Stone Age
Stone Age
from the Last Interglacial, and hints at how early modern humans dispersed into previously uninhabitable environments. This notwithstanding, the term still usefully denotes the presence of tanged tools in North African Middle Stone Age
Stone Age
assemblages. Tanged tools persisted in North Africa
North Africa
until around 30,000 years ago, with the youngest sites located in Northwest Africa. By this time, the Aterian
Aterian
lithic industry had long ceased to exist in the rest of North Africa due to the onset of the Ice Age, which in North Africa, resulted in hyperarid conditions. Assemblages with tanged tools, 'the Aterian', therefore have a significant temporal and spatial range. However, the exact geographical distribution of this lithic industry is uncertain. The Aterian's spatial range is thought to have existed in North Africa
North Africa
up to the Western Desert,[9] with no Aterian
Aterian
sites known from the Nile Valley.[10] Possible Aterian
Aterian
lithic tools have also been discovered in Middle Paleolithic
Paleolithic
deposits in Oman
Oman
and the Thar Desert.[1] Associated behaviour[edit] The Aterian
Aterian
is associated with early Homo sapiens at a number of sites in Morocco.[3] Some studies of comparative skeletal morphology have suggested that these people exist on the same morphological continuum as the Jebel Irhoud
Jebel Irhoud
specimens, currently thought to date to 160,000 years ago. The 'Aterian' fossils also display similarities to the earliest modern humans found out of Africa at Skhul and Qafzeh in the Levant, and they are broadly contemporary to them.[11] Apart from producing a highly distinctive and sophisticated stone tool technology, these early North African populations also seem to have engaged with symbolically constituted material culture, creating what are amongst the earliest African examples of personal ornamentation.[5] Such examples of shell 'beads' have been found far inland, suggesting the presence of long distance social networks.[12] Studies of the variation and distribution of the Aterian
Aterian
have also now suggested that associated populations lived in subdivided populations, perhaps living most of their lives in relative isolation and aggregating at particular times to reinforce social ties.[8] Such a subdivided population structure has also been inferred from the pattern of variation observed in early African fossils of Homo sapiens.[13] Associated faunal studies suggest that the people making the Aterian exploited coastal resources as well as engaging in hunting.[14] It has so far been difficult to estimate whether Aterian
Aterian
populations further inland were exploiting freshwater resources as well. Studies have suggested that hafting was widespread, perhaps to maintain flexibility in the face of strongly seasonal environment with a pronounced dry season.[3] Scrapers, knives and points all seem to have been hafted, suggesting a wide range of activities were facilitated by technological advances. It is probably that plant resources were also exploited. Although there is no direct evidence from the Aterian
Aterian
yet, plant processing is evidenced in North Africa
North Africa
from as much as 182,000 years ago.[15] Locations[edit] North Africa[edit]
