Geography comments: "Tongo Maaré Diabal (TMD) lies in a narrow strip of flatland between two sheer sandstone escarpments (Bandiagara and Dyoundé), 1 km north of the modern town of Douentza, Mali" (basis of coordinate).
"Seven radiocarbon dates provide a 650 year time span for the excavation’s discrete sequence of building events (horizons)". Horizon 5 ranges from AD 1000-1150.

Archaeology: buildings,ceramics,hearths,metal tools,stone tools,other artifacts,other structures

Habitat comments: "Tongo Maaré Diabal is a settlement mound, 9 ha in extent, and approximately 3 to 4.5 m in elevation above the surrounding plain. The site is at a crossroads on land routes connecting Timbuktu and Gao to the Malian interior, as well as north-western Burkina Faso to the Niger Bend. The sequence of archaeological deposits contains five horizons of superimposed earthen buildings. The occupation appears to have been continuous from the site’s foundation to its abandonment".
"In Horizon 5 the northern concession shows the sudden construction of a row of three small mudbrick rooms lining the well-defined middle passageway. Metallurgical activity is still ongoing in the area with a concentration of working slag and burned earth within a room, possibly a forge. The floor deposits contained copious amounts of charcoal and iron objects. The southern structures likewise are modified to form a row of small rooms comparable to those in the north. Overall this is the most significant spatial modification of the area in two centuries. Two technically and visually distinctive pottery traditions occurred at the site from the beginning of its occupation. Large stone grinding basins were found in some rooms, along with frequent finds of hand grinders throughout the sequence, evidencing the processing of grains in and around the buildings".

Methods
Life forms: carnivores,rodents,ungulates,birds,fishes

Sampling methods: quarry,screenwash

Sample size: 413 specimens

Years: 1993, 1995, 1996, 2010

Sampling comments: "In 1993, 1995 and 1996 two 4 x 4 m units were excavated, termed A and B, joined by a 1 x 4 m baulk (C). This area was excavated to a maximum depth of 4 m before reaching sterile soil. A further 4 x 4 m unit (D) located on the western part of the site, was only excavated to a depth of 1.3 m".
"The main exposure of the 2010 excavations was positioned directly adjacent to units A, B and C. An initial 9 x 5 m trench (unit E) was extended to the northwest by a further 7 x 5 m area (unit F) for a total excavated area of 125 m2 (Exposure 1). In these two units, only the uppermost occupation horizon was excavated, 50 to 80 cm below the surface. A 7 x 4 m unit (Exposure 2) was also excavated on the eastern part of the site".
