<strong>Tichitt</strong>-<strong>Walata</strong> <strong>and</strong> <strong>the</strong> <strong>Middle</strong> <strong>Niger</strong>: evidence for<br />
cultural contact in <strong>the</strong> second millennium Be<br />
KEVIN C. MACDoNALD<br />
Introduction: palaeohydrology <strong>and</strong> previous research<br />
A cultural connection between <strong>the</strong> <strong>Tichitt</strong>-<strong>Walata</strong> complex <strong>of</strong> sou<strong>the</strong>astern Mauritania <strong>and</strong> <strong>the</strong> later<br />
civilisations <strong>of</strong> <strong>the</strong> <strong>Middle</strong> <strong>Niger</strong> has long been hypo<strong>the</strong>sised (McIntosh 1995; Holl 1985a; Munson<br />
1980). Soninke oral traditions concerning <strong>the</strong> origins <strong>of</strong> <strong>the</strong> Empire <strong>of</strong> Ghana (particularly <strong>the</strong> myth<br />
<strong>of</strong> Dinga; Dieterlen <strong>and</strong> Sylla 1992), affinities in ceramic traditions (McIntosh 1995), <strong>and</strong> <strong>the</strong> existence<br />
<strong>of</strong> vestigial Soninke-speaking populations in <strong>the</strong> vicinity <strong>of</strong> <strong>Tichitt</strong> (Munson 1980) have all<br />
been used to assert population movement from Mauritania to <strong>the</strong> <strong>Middle</strong> <strong>Niger</strong> sometime before <strong>the</strong><br />
first millennium AD. It now appears that a fossil drainage <strong>of</strong> <strong>the</strong> <strong>Middle</strong> <strong>Niger</strong> supplies <strong>the</strong> concrete<br />
evidence for this interaction which has long been sought.<br />
The Merna, a region <strong>of</strong> <strong>the</strong> modern republic <strong>of</strong> Mali, is one <strong>of</strong> <strong>the</strong> <strong>Niger</strong> River's many desiccated<br />
basins. Its vanished waterways were first investigated early this century by <strong>the</strong> geologist<br />
Furon (1929), who indicated <strong>the</strong> presence <strong>of</strong> two fossil drainages in <strong>the</strong> Merna - <strong>the</strong> Bras de<br />
Nampala <strong>and</strong> <strong>the</strong> Bras du Debo. The latter, now known as <strong>the</strong> Fala de Molodo, was a distinct <strong>and</strong><br />
narrow dry-channel which could be followed without difficulty from <strong>the</strong> <strong>Niger</strong> to <strong>the</strong> Boulel Ridge.<br />
To <strong>the</strong> north, he traced <strong>the</strong> Fala's extension (<strong>the</strong> Bras de Nampala) by following low-lying ponding<br />
areas or mares across <strong>the</strong> l<strong>and</strong>scape (Fig. 1). Today, despite <strong>the</strong> advent <strong>of</strong> aerial photography, we are<br />
not much far<strong>the</strong>r in our underst<strong>and</strong>ing. Some recent studies indicate that <strong>the</strong> Bras de Nampala was<br />
in fact a chain <strong>of</strong> 'palaeolakes' (Raimbault <strong>and</strong> Dutour 1989; MacDonald <strong>and</strong> Van Neer 1994).<br />
O<strong>the</strong>rs have used <strong>the</strong> same evidence, to consider it as a 'water corridor', with a surrounding<br />
backswamp (Furon 1929; Togola 1993; McIntosh pers.comm.).<br />
In <strong>the</strong> 1950s, Monod <strong>and</strong> Mauny (1957) <strong>of</strong> IFAN visited <strong>the</strong> Merna when <strong>the</strong>ir attention was<br />
drawn to <strong>the</strong> vast, 400 m long kjokkenmodding <strong>of</strong> Kobadi by a local administrator. Strangely, it was<br />
to remain <strong>the</strong> only site predating <strong>the</strong> Empire <strong>of</strong> Ghana known from <strong>the</strong> region until <strong>the</strong> 1980s.<br />
In 1984 an ambitious campaign was launched by Raimbault <strong>and</strong> Togola whose survey work<br />
confirmed <strong>the</strong> presence on <strong>the</strong> ground <strong>of</strong> 102 sites between Nampala <strong>and</strong> Lere north <strong>of</strong> <strong>the</strong> Boulel<br />
Ridge (Togola <strong>and</strong> Raimbault 1991). Additionally, <strong>the</strong>y did survey work in <strong>the</strong> portion <strong>of</strong> <strong>the</strong> Macina<br />
south <strong>of</strong> <strong>the</strong> Boulel Ridge which has sometimes been considered as part <strong>of</strong> <strong>the</strong> Merna (cf. Haal<strong>and</strong><br />
1980), but is also known as <strong>the</strong> Kareri region. Most <strong>of</strong> <strong>the</strong> localities visited by Togola <strong>and</strong> Raimbault

were large tell sites, with only one fur<strong>the</strong>r 'Neolithic' site, that <strong>of</strong> Tiabel Goudiodie, being discovered.<br />
Raimbault has since returned to <strong>the</strong> Merna to excavate at Kobadi (Raimbault et al. 1987;<br />
Raimbault <strong>and</strong> Dutour 1989).<br />
The 1989 <strong>and</strong> 1990 Merna Survey<br />
In <strong>the</strong> winter <strong>of</strong> 1989/1990 a systematic survey <strong>of</strong> <strong>the</strong> Merna region was carried out by T. Togola <strong>and</strong><br />
myself. The purpose <strong>of</strong> <strong>the</strong> mission was to establish a cultural chronology for <strong>the</strong> region, particularly<br />
with a view to studying changes in site distribution <strong>and</strong> environmental change over time. After<br />
<strong>the</strong> survey, several sites were selected for test excavations to allow <strong>the</strong> chronological placement <strong>of</strong><br />
surface materials. In total 137 archaeological sites were visited, surface collected, <strong>and</strong> plotted on<br />
aerial photos during our survey. The work <strong>of</strong> Togola was presented as his doctoral <strong>the</strong>sis (Togola<br />
1993), while my work on <strong>the</strong> project formed a portion <strong>of</strong> my own (MacDonald 1994).<br />
Until <strong>the</strong> present decade, occupation sites pre-dating <strong>the</strong> advent <strong>of</strong> metallurgy were a rarity in<br />
<strong>the</strong> vicinity <strong>of</strong> <strong>the</strong> modern delta . Indeed, no vestiges <strong>of</strong>\human occupation from before 200 cal BC<br />
are yet known from <strong>the</strong> interior <strong>of</strong> <strong>the</strong> modern Inl<strong>and</strong> <strong>Niger</strong> Delta itself, a phenomenon attributed<br />
tentatively to alluviation <strong>and</strong>/or to highly seasonal settlements before this time (R.J. McIntosh 1983).<br />
Remarkably, <strong>the</strong> Merna survey succeeded in locating 28 sites belonging to what has conventionally<br />
been termed <strong>the</strong> 'LSA' or 'Neolithic' .<br />
Four distinCt ceramic facies were identified at <strong>the</strong>se 28 sites, representing two broad cultural<br />
traditions. Each facies was named after a type assemblage most clearly representing all <strong>of</strong> its facets<br />
(Kobadi, Beretouma, Ndondi Tossokel <strong>and</strong> Faita). It should be stressed, however, that although<br />
assemblages were invariably dominated by a single set <strong>of</strong> wares, materials attributable to o<strong>the</strong>r<br />
facies were usually also represented in <strong>the</strong>m. Test excavation <strong>and</strong> surface associations indicate that<br />
three <strong>of</strong> <strong>the</strong>se facies were at least partially contemporaneous, whilst <strong>the</strong> fourth (Faita facies) represents<br />
a later phase in <strong>the</strong> region's occupation (ca. 800BC - AD 200). The three contemporary facies<br />
would appear to date to between 2000 <strong>and</strong> 800 Be on <strong>the</strong> basis <strong>of</strong> an admittedly small suite <strong>of</strong> eight<br />
radiocarbon dates from three sites (MacDonald 1994, MacDonald <strong>and</strong> Van Neet 1994). For <strong>the</strong><br />
purposes <strong>of</strong> this paper we will limit discussion to this period.<br />
Kobadi facies, Kobadi tradition (Fig. 2)<br />
First characterised by Mauny (1972), Kobadi ceramics are characterised by thick-walled, open <strong>and</strong><br />
restricted simple-rimmed vessels <strong>of</strong> a usually globular shape. The internal rim diameters <strong>of</strong> <strong>the</strong>se<br />
vessels usually range from 28 to 40 cm.<br />
They are decorated principally with pivoting stylus <strong>and</strong> pivoted, dragged or rocked comb (24-<br />
60% <strong>of</strong> motif occurrences). O<strong>the</strong>r important means <strong>of</strong> decor include: twine impression (usually<br />
along <strong>the</strong> rim), braided twine roulettes (cf. Hurley 1979; types 210-212), twisted twine roulettes (cf.<br />
Soper 1985: 36), fabric impression (cf. Bedaux <strong>and</strong> Lange 1983) <strong>and</strong> incised or complex punctate<br />
decors <strong>of</strong>ten rendered in 'wavy' patterns (cf. Fig. 2.c-d).<br />
Temper is one <strong>of</strong> <strong>the</strong> most distinctive elements <strong>of</strong> <strong>the</strong> Kobadi Tradition. Sponge spicules <strong>and</strong><br />
coarse s<strong>and</strong> were virtually <strong>the</strong> only tempers utilised in Kobadi wares. There is an increasing literature<br />
concerning sponge spiCUle temper in African pottery (cf. Brissaud <strong>and</strong> Houdayer 1986; Adamson<br />
et al. 1987; McIntosh <strong>and</strong> MacDonald 1989). In <strong>the</strong> Merna, we are dealing with high content samples<br />
which contain spicules only (no gemmules or gemulscleres), almost certainly indicative <strong>of</strong> <strong>the</strong><br />
genus Potamolipis (a freshwater sponge, indigenous throughout <strong>the</strong> <strong>Niger</strong> River system) (McIntosh<br />
<strong>and</strong> MacDonald 1989). Spicule content, measured by thin-section point counts, in samples from<br />
Kobadi <strong>and</strong> Tiabel Goudiodie, may be placed at 18 to 25% <strong>of</strong> content (200 point samples). This<br />
measure far exceeds that for known <strong>Middle</strong> <strong>Niger</strong> pottery <strong>of</strong> later periods. Such quantities would

argue for some sort <strong>of</strong> intentional concentration <strong>of</strong> spicules in <strong>the</strong> clay: ei<strong>the</strong>r through <strong>the</strong> intentional<br />
ga<strong>the</strong>ring <strong>of</strong> clay from dry season floodplains'where dead sponges are clustered, or through<br />
<strong>the</strong> physical grinding, burning or macerating <strong>of</strong> whole specimens. The latter practices have been<br />
demonstrted along <strong>the</strong> White Nile between 3500 <strong>and</strong> 1500 BP by Adamson et at. (1987). Sponge<br />
spicule tempering would appear to be a distinctive technology, associated with peoples exploiting<br />
riverine resources.<br />
Aside from pottery, Kobadi facies localities possess a plethora <strong>of</strong> bone points, hooks <strong>and</strong> (more<br />
rarely) harpoons. Additionally, polished stone points are known from excavated contexts (Raimbault<br />
<strong>and</strong> Dutour 1987; MacDonald 1994). Stope grinders <strong>and</strong> objets de parure are rare. Geometric<br />
microliths though present at earlier localities (i.e. Tiabel Goudiodie), seem to disappear in favour <strong>of</strong><br />
a crude assortment <strong>of</strong> retouched flakes at later sites (e.g. Kobadi <strong>and</strong> Kolima-Sud).<br />
All Kobadi facies sites occur within <strong>the</strong> bounds <strong>of</strong> <strong>the</strong> ancient floodplain (Fig. 1). All <strong>of</strong> <strong>the</strong><br />
sites are kjokkenmoddings, <strong>and</strong> were probably initially chosen for occupation because <strong>of</strong> <strong>the</strong>ir elevation<br />
above <strong>the</strong> surrounding plain. At Kobadi, excavations by Raimbault have shown that <strong>the</strong><br />
original site surface was 1-2 m above <strong>the</strong> floodplain (Raimbault <strong>and</strong> Dutour 1989), <strong>and</strong> similar<br />
results have been achieved by our team at Kolima Sud ' (MacDonald 1994, MacDonald <strong>and</strong> Van<br />
Neer 1994). Additionally, at Kobadi it appears that <strong>the</strong> habitation area stretched along <strong>the</strong> top <strong>of</strong> <strong>the</strong><br />
bone midden <strong>and</strong> burial area, although no post holes or daub fragments have yet been reported.<br />
1251-1 follows <strong>the</strong> same pattern as Kobadi in terms <strong>of</strong> shape, except that it would have been situated<br />
on an islet within a lake. Tiabel Goudiodie is an enormous shell midden <strong>of</strong> over 3m in height<br />
situated directly beside <strong>the</strong> ancient Fala de Molodo channel.<br />
In size, <strong>the</strong> sites <strong>of</strong> <strong>the</strong> Kobadi facies far exceed <strong>the</strong>ir peers, ranging between 1.9 <strong>and</strong> 7.6 ha in<br />
expanse. This may be due to greater population aggregations at Kobadi localities, a permanent as<br />
opposed to a seasonal occupation <strong>of</strong> <strong>the</strong> sites, <strong>the</strong>ir depositional nature (kjokkenmoddings), or to a<br />
longer period <strong>of</strong> occupation for <strong>the</strong>se sites (with horizontal displacements).<br />
Economically, <strong>the</strong> Kobadi facies would appear to be 'hunter-fisher', with catfish, Tilapia, Nile<br />
perch <strong>and</strong> aquatic mammals dominating faunal assemblages (Raimbault et at. 1987, MacDonald<br />
<strong>and</strong> Van Neer 1994).<br />
Beretouma facies, Kobadi tradition (Fig. 3)<br />
The Beretouma facies is perhaps best regarded as a phase <strong>of</strong> <strong>the</strong> Kobadi tradition ra<strong>the</strong>r than as a<br />
discrete entity. It is characterised by distinctive simple rimmed, open bowls with internal diameters<br />
varying between 34 <strong>and</strong> 48 cm, although a few smaller vessels (c.24 cm) are known.<br />
Their decor is highly distinctive, consisting <strong>of</strong> twisted <strong>and</strong> braided twine roulettes on <strong>the</strong>ir<br />
exterior, burnishing <strong>of</strong> <strong>the</strong>ir lip <strong>and</strong> interior, <strong>and</strong> <strong>the</strong> decoration <strong>of</strong> <strong>the</strong> interior with one rank <strong>of</strong><br />
rocker comb decor. The vessels are also unique in being consistently black in colour (fired in a<br />
reducing atmosphere). In terms <strong>of</strong> temper, only 12% <strong>of</strong> such vessels recovered in <strong>the</strong> survey were<br />
grog tempered, <strong>the</strong> remainder were tempered with sponge.<br />
There are three localities located in <strong>the</strong> survey which bear quantities <strong>of</strong> Beretouma ware associated<br />
with Kobadi <strong>and</strong> Ndondi Tossokel ceramics. They are all <strong>of</strong> substantial size, <strong>the</strong> largest being<br />
<strong>the</strong> 12.5 ha site <strong>of</strong> Kolima Sud. The remaining two, 1121-4 <strong>and</strong> 1121-5 are both situated on <strong>the</strong><br />
raised beaches which form a ring around <strong>the</strong> sou<strong>the</strong>rn portion <strong>of</strong> "Palaeolake Beretouma". Both<br />
sites are semi-circular high density artifact scatters abutting <strong>the</strong> lake bed.<br />
We have little economic evidence associated with Beretouma pottery o<strong>the</strong>r than numerous fish<br />
remains (MacDonald 1994).

Ndondi Tossokelfacies, Dhar <strong>Tichitt</strong> tradition (Fig. 4)<br />
Elements <strong>of</strong> <strong>the</strong> Ndondi Tossokel tradition first appeared like uninvited guests in elements <strong>of</strong> <strong>the</strong><br />
Kobadi assemblage illustrated by Mauny (1972: Plate n.8-10). In retrospect, parallels between <strong>the</strong>se<br />
vessels <strong>and</strong> those from <strong>Tichitt</strong>-<strong>Walata</strong> should have been obvious at <strong>the</strong> time (Mauny 1972: Plates V<br />
VII; Holl 1986: Fig.23). However it was not until I had a chance to study <strong>the</strong> Dhar <strong>Tichitt</strong> assemblage<br />
curated by Pat Munson at Indiana University in 1993, that I realised <strong>the</strong> Ndondi Tossokel<br />
tradition <strong>and</strong> that <strong>of</strong> <strong>Tichitt</strong>-<strong>Walata</strong> to be one <strong>and</strong> <strong>the</strong> same (compare Figs 4 <strong>and</strong> 5).<br />
The Ndondi Tossokel tradition comprises both open simple-rimmed vessels <strong>and</strong> closed evertedrimmed<br />
vessels, with <strong>the</strong> latter being <strong>the</strong> more numerous. The everted rim vessels have internal rim<br />
diameters <strong>of</strong> between 12 <strong>and</strong> 22 cm. The diameters <strong>of</strong> open simple rimmed vessels range between<br />
14 <strong>and</strong> 38 cm.<br />
In addition to <strong>the</strong> distinctive shape <strong>of</strong> <strong>the</strong>ir everted rims (cf. Fig. 4 for <strong>the</strong> three principal variations),<br />
<strong>the</strong>ir decor <strong>and</strong> its manner <strong>of</strong> application are most characteristic. Tightly spaced cord-wrapped<br />
cord roulettes descending vertically from <strong>the</strong> lip or collar <strong>of</strong> <strong>the</strong> vessel are a hallmark <strong>of</strong> Ndondi<br />
Tossokel wares, comprising between 39 <strong>and</strong> 59% <strong>of</strong> total motif occurrences. Additionally, impressions<br />
using <strong>the</strong> same tool are common. O<strong>the</strong>r decor attributes include applied plastic nubbins <strong>and</strong><br />
fillets (cf. Rye 1981: 94) which are usually in <strong>the</strong> shape <strong>of</strong> teats <strong>and</strong> are applied below or within <strong>the</strong><br />
b<strong>and</strong> <strong>of</strong> cord-wrapped stick decor, <strong>and</strong> simple incised lines or arcs (Fig. 4b). Red slip is also very<br />
common, with traces visible on <strong>the</strong> lip <strong>of</strong> most vessels. The fabric <strong>of</strong> Ndondi Tossokel pottery is<br />
distinctive, usually consisting <strong>of</strong> grog <strong>and</strong> coarse s<strong>and</strong>, sometimes augmented by chaff (ca. 5-30%<br />
<strong>of</strong> sherds depending on <strong>the</strong> assemblage). In texture, <strong>the</strong>y are harder than Beretouma or Kobadi<br />
wares, <strong>and</strong> tend to have thinner walls.<br />
Although lithics are scarce in <strong>the</strong> Merna, probably due to <strong>the</strong> lack <strong>of</strong> local rock sources aside<br />
from schist <strong>and</strong> s<strong>and</strong>stone, Ndondi Tossokel sites usually provide an assortment <strong>of</strong> projectile points<br />
comparable to those known from Dhars <strong>Tichitt</strong> <strong>and</strong> <strong>Walata</strong> (cf. Amblard 1984, types 68, 78 <strong>and</strong> 79).<br />
Also, polished stone hachettes, stone rings <strong>and</strong> beads which correlate well with <strong>the</strong> findings <strong>of</strong><br />
Amblard (1984) are associated with <strong>the</strong> Ndondi Tossokel facies.<br />
In most instances <strong>the</strong> Ndondi Tossokel sites are characterised by <strong>the</strong> presence <strong>of</strong> what may be<br />
called "mini-middens". These are relatively small, one to five metre diameter, rounded mounds no<br />
more than 50 cm in height containing broken pottery, stone chips <strong>and</strong> bone. In between <strong>the</strong>se <strong>the</strong>re<br />
is only a thin scatter <strong>of</strong> cultural materials. Munson (pers. comm.) has suggested that similar "bumps"<br />
observed in <strong>the</strong> Dhar <strong>Tichitt</strong> region, were wind-eroded rubbish pits or sherd-lined earth ovens.<br />
Alternatively, <strong>the</strong>se could be <strong>the</strong> remains <strong>of</strong> refuse accumulations from beside living areas, or even<br />
hydrological phenomena. Still, it is interesting that "mini-middens;' do not occur at sites <strong>of</strong> o<strong>the</strong>r<br />
traditions situated within <strong>the</strong> inundatable plain.<br />
Except when <strong>the</strong>y are mixed with Beretouma ceramics, Ndondi Tossokel facies sites do not<br />
occur within <strong>the</strong> ancient floodplain, but on its margins (Fig. 1). They feature little debris accumulation,<br />
with <strong>the</strong>ir deposits never rising more than a metre above <strong>the</strong> surrounding area. In size <strong>the</strong>y are<br />
much smaller than Kobadi sites, usually not exceeding 1.5 ha. A notable exception to this is <strong>the</strong> 6 ha<br />
escarpment-top occupation <strong>of</strong> Saberi Faita, but it is only superficially stratified. These sites give <strong>the</strong><br />
impression <strong>of</strong> ephemeral occupations by highly mobile groups.<br />
Cattle <strong>and</strong> ovicaprine remains, as well as terracotta cattle statuettes, have been positively associated<br />
with Ndondi Tossokel facies ceramics at Kolima-Sud <strong>and</strong> o<strong>the</strong>r sites (MacDonald 1994).<br />
This brings into question claims <strong>of</strong> Raimbault (et al. 1987) concerning <strong>the</strong> association <strong>of</strong> cattle<br />
remains with <strong>the</strong> Kobadi tradition. As has been argued elsewhere, we believe it more probable that<br />
cattle remains at Kobadi stem from intrusive Ndondi Tossokel facies deposits at <strong>the</strong> site (MacDonald<br />
<strong>and</strong> Van Neer 1994).

Dhar <strong>Tichitt</strong> Tradition Ceramics (Figure 6)<br />
250km<br />
• Hassi el Ablod<br />
Some mention should be made here concerning <strong>the</strong> main aspects <strong>of</strong> <strong>the</strong> <strong>Tichitt</strong> ceramic tradition to<br />
which parallels have been drawn. Although presented extensively in Munson's (1971) <strong>the</strong>sis, a<br />
detailed characterisation <strong>of</strong> <strong>the</strong>se assemblages has never been published. It should be evident from<br />
what follows that I still subscribe to Munson's (1971, 1976) chronological hypo<strong>the</strong>sis, albeit with<br />
some modifications, <strong>and</strong> not to Holl's (1986) seasonality hypo<strong>the</strong>sis. Most <strong>of</strong> my reasons can be<br />
found in Munson's own rebuttal to Holl (Munson 1989), but I would also stress <strong>the</strong> integrity <strong>and</strong><br />
clarity <strong>of</strong> Munson's original ceramic sequence.<br />
The earliest <strong>Tichitt</strong> ceramics, those assigned to <strong>the</strong> Akreijit through Goungou phases (I-III), are<br />
strictly simple rimmed vessels. All are chaff tempered, <strong>and</strong> decor consists initially <strong>of</strong> comb decor<br />
gradually replaced in turn by impressed cord wrapped stick <strong>and</strong> twisted twine roulettes. Chaff in
436 Kevin C. MacDonald<br />
fact remains <strong>the</strong> almost exclusive temper <strong>of</strong> <strong>the</strong> <strong>Tichitt</strong> tradition .throughout its long span <strong>of</strong> years,<br />
with s<strong>and</strong> <strong>and</strong> grog occasionally added or substituted. Everted rims, as well as red slip, only begin to<br />
appear in <strong>the</strong> Nkahl <strong>and</strong> Naghez phases (IV-V), with twisted twine remaining <strong>the</strong> dominant decor.<br />
By <strong>the</strong> Chebka <strong>and</strong> Arriane phases (VI-VII) everted rims have become common accounting for<br />
c.40-50% <strong>of</strong> all rims. Cord-wrapped stick motifs become common again, <strong>and</strong> start to be used as<br />
roulettes instead <strong>of</strong> only for impression (cf. Fig. 5 for ceramics from phases VI-VII). Finally, in <strong>the</strong><br />
AkJinjeir phase (VIII) applied plastic motifs become common, <strong>and</strong> vessels grow much larger <strong>and</strong><br />
have less decor.<br />
The <strong>Tichitt</strong> assemblages only become analogous with those· <strong>of</strong> Ndondi Tossokel'during <strong>the</strong><br />
Chebka <strong>and</strong> Arriane phases (e.g. higher proportions <strong>of</strong> everted rims, rouletted cord-wrapped decor,<br />
etc.). Their resemblance is not absolute, however, as some <strong>Tichitt</strong> vessels <strong>of</strong> <strong>the</strong>se phases feature<br />
knotted twine decor (cf. Hurley 1979: Type 165), a manipulation entirely absent in <strong>the</strong> Merna.<br />
Discussion: regional chronology<br />
Dating <strong>the</strong> Kobadi facies<br />
The earliest known date for <strong>the</strong> human occupation <strong>of</strong> <strong>the</strong> <strong>Middle</strong> <strong>Niger</strong> comes from <strong>the</strong> site <strong>of</strong> Tiabel<br />
Goudiodie. This site has been dated on freshwater oyster shells (E<strong>the</strong>ria elliptica) to between 2570<br />
<strong>and</strong> 2410 cal BC (Togola <strong>and</strong> Raimbault 1991). As usual with dates on freshwater materials, however,<br />
a carbonate reservoir effect <strong>of</strong> several hundred years should be allowed for, thus an initial<br />
occupation date <strong>of</strong> around 2000 BC is more likely for <strong>the</strong> site.<br />
It is difficult to know what <strong>the</strong> sequence <strong>of</strong> dates from <strong>the</strong> site <strong>of</strong> Kobadi actually date culturally,<br />
since all but one <strong>of</strong> <strong>the</strong>m are conventional collagen dates run on surface-collected bone, <strong>and</strong><br />
Ndondi Tossokel materials are known to also occur on <strong>the</strong> site (Raimbault <strong>and</strong> Dutour 1989,<br />
MacDonald 1994). The earliest date, 1740-1510 BC, was run on burned hippopotamus bone, <strong>and</strong> is<br />
thus most likely associated with <strong>the</strong> aquatically based Kobadi tradition. More recently, an as yet<br />
incompletely published date (Georgeon et al. 1992: 86) was run on an unspecified material from <strong>the</strong><br />
1989 excavations. Its result, 1740-1440 BC (3305±80 BP), is very close to that <strong>of</strong> <strong>the</strong> early 'hippo<br />
bone'. The middle dates are less certain, coming from indeterminate burned bone (1260-900 BC)<br />
<strong>and</strong> mammalian vertebrae (930-610 BC) respecti vely, <strong>the</strong> latter date coming from samples collected<br />
by Mauny in 1954 (Georgeon et at. 1992). The most recent date (770 to 380 BC) was run on <strong>the</strong><br />
cranium <strong>of</strong> a late inhumation recovered eroding from <strong>the</strong> midden surface. It is evident that we are<br />
dealing with a lengthy <strong>and</strong> probably multi-faceted occupation at Kobadi (c. 1750-400 BC). How<br />
punctuated this may have been by gaps in occupation, <strong>and</strong> <strong>the</strong> extent to which typical Kobadi wares<br />
continued throughout it, will only be clarified with <strong>the</strong> publication <strong>of</strong> a complete excavation report<br />
by Raimbault.<br />
A single radiocarbon date has recently been run on hippo ivory from <strong>the</strong> lowest Kobadi facies<br />
occupation layer <strong>of</strong> Kolima-Sud (layer V, KLS- l lv.25). The result <strong>of</strong> this apatite determination was<br />
as follows: 3365±70 BP11740-1530 cal BC (GX-21192-AMS). This date is comparable to <strong>the</strong> two<br />
earliest dates from Kobadi itself, <strong>and</strong> when bracketed by a date associated with Ndondi-Tossokel<br />
ceramics in <strong>the</strong> upper Kolima-Sud sequence (see below), suggests a minimum temporal range <strong>of</strong><br />
1750 to 1300 BC for <strong>the</strong> Kobadi facies.<br />
Dating <strong>the</strong> Ndondi Tossokel <strong>and</strong> Beretouma facies<br />
Test excavations carried out at <strong>the</strong> site <strong>of</strong> Kolima-Sud in 1990 provide our only definitive date for<br />
Ndondi Tossokel <strong>and</strong> Beretouma ceramics in context. There, two sondages revealed occupational<br />
deposits <strong>of</strong> 2.5 m in depth containing four principal occupational layers (MacDonald 1994). In
<strong>Tichitt</strong>- <strong>Walata</strong> <strong>and</strong> <strong>the</strong> <strong>Middle</strong> <strong>Niger</strong>: evidence for cultural contact in <strong>the</strong> second millennium Be 437<br />
layers I to III cattle remains <strong>and</strong> cattle figurines appear with Ndondi Tossokel ceramics. Kobadi<br />
ceramics, which were present from <strong>the</strong> sites first occupation (layers IV <strong>and</strong> V), disappear before<br />
layer III <strong>and</strong> are replaced fully by Beretouma ceramics which continue beside those <strong>of</strong> Ndondi<br />
Tossokel. In <strong>the</strong> absence <strong>of</strong> substantive charcoal deposits, a cattle molar (Bos cf taurus, M2) from<br />
<strong>the</strong> Layer IIIIII interface (KLS-l, Iv. 1 0) was submitted to Geochron Laboratories for apatite dating.<br />
The result was: 3084±73 BP11420-1230 cal BC (GX-19814-AMS) (MacDonald <strong>and</strong> Van Neer 1994).<br />
Also, at least for <strong>the</strong> dating <strong>of</strong> N dondi Tossokel tradition, we may turn to <strong>the</strong> Dhar <strong>Tichitt</strong> Phase<br />
VI-VII Chebkal Arriane wares with which it is closely stylistically associated. The calibration <strong>of</strong><br />
dates assigned by Munson (1989) to <strong>the</strong>se phases, <strong>and</strong> <strong>the</strong> poorly chronologically defined Naghez<br />
phase, would place <strong>the</strong>ir one sigma range between 1400 <strong>and</strong> 800 Be. This would appear to be in line<br />
with our single date from <strong>the</strong> Merna. But here, unfortunately, we venture onto <strong>the</strong> much debated<br />
ground <strong>of</strong> Dhar <strong>Tichitt</strong> chronology (Holl 1986; Munson 1989; Muzzolini 1989). Suffice to say that<br />
ano<strong>the</strong>r re-evaluation <strong>of</strong> <strong>the</strong> Dhar <strong>Tichitt</strong> sequence is in progress, which will hopefully clarify this<br />
matter for <strong>the</strong> time being (MacDonald <strong>and</strong> Munson in prep.).<br />
Conclusion: <strong>the</strong> Merna before <strong>the</strong> Empire <strong>of</strong> Ghana<br />
In <strong>the</strong> Merna we have a particularly early West African example <strong>of</strong> multi-cultural contemporaneity<br />
within a single region. There are at least two groups involved. The Kobadi Tradition, with physical<br />
<strong>and</strong> material cultural roots to <strong>the</strong> nor<strong>the</strong>ast at Hassi el Abiod (Raimbault <strong>and</strong> Dutour 1989, Georgeon<br />
et al. 1992), <strong>and</strong> <strong>the</strong> Ndondi Tossokel tradition with material <strong>and</strong> economic roots to <strong>the</strong> northwest at<br />
Dhars <strong>Tichitt</strong>-<strong>Walata</strong>.<br />
The earlier occupants <strong>of</strong> <strong>the</strong> region are manifestly <strong>the</strong> Kobadi folk, robust "Mechtoid" fisherhunter-ga<strong>the</strong>rers<br />
who first colonised <strong>the</strong> shrinking lacustrine region around 2000 Be. Human osteology<br />
has been used to link <strong>the</strong>m with similar early Holocene fisher-hunter-ga<strong>the</strong>rer populations<br />
from <strong>the</strong> Saharan site <strong>of</strong> Hassi el Abiod (Georgeon et al. 1992). Their movement to <strong>the</strong> Merna has<br />
been portrayed as a response to environmental change - a retreat with <strong>the</strong> lacustrine regions which<br />
maintained <strong>the</strong>ir aquatic subsistence lifestyle. Upon <strong>the</strong>ir arrival in <strong>the</strong> Merna, <strong>the</strong>y were still producing<br />
a geometric microlith industry, but this seems to have given way to an opportunistic utilised<br />
flake industry (MacDonald 1994). Their hunting <strong>and</strong> fishing prowess in this virgin l<strong>and</strong>scape appears<br />
to have been epic, with kills <strong>of</strong> elephants, hippos, crocodiles, <strong>and</strong> massive Nile perch <strong>and</strong><br />
catfish <strong>of</strong> up to 2.5 m in length. Only at Kobadi <strong>and</strong> Kolima Sud, where ceramics <strong>of</strong> <strong>the</strong> Ndondi<br />
Tossokel facies are associated, do we have any evidence for food production associated with <strong>the</strong><br />
Kobadi tradition.<br />
Around 1300 BC we have evidence that a new group had entered <strong>the</strong> zone with close affinities<br />
to Dhar <strong>Tichitt</strong>'s ChebkalArriane phase (c.1400-800 BC). It would seem that <strong>the</strong> Dhar <strong>Tichitt</strong> tradition,<br />
with only small quantities <strong>of</strong> arable l<strong>and</strong>, had long been under pressure to exp<strong>and</strong>. Indeed,<br />
settlement hierarchies first visible at Dhars <strong>Tichitt</strong> <strong>and</strong> <strong>Walata</strong> around this time may represent traces<br />
<strong>of</strong> simple chiefdoms organised to defend <strong>the</strong> decreasing supply <strong>of</strong> l<strong>and</strong> (Munson 1980; Holl 1985a).<br />
It is even possible that population pressures <strong>and</strong> territorial restrictions were responsible for a shift to<br />
<strong>the</strong> actual domestication <strong>of</strong> millet at <strong>the</strong> site (Munson 1976; Amblard <strong>and</strong> Pemes 1989). From this<br />
time, <strong>of</strong>f-shoots <strong>of</strong> <strong>the</strong> Dhar <strong>Tichitt</strong> tradition begin to appear in small mobile settlements along <strong>the</strong><br />
margins <strong>of</strong> <strong>the</strong> Merna's inundatable plain. Their economy would seem to have been based on pastoralism,<br />
but we have no data to show us whe<strong>the</strong>r <strong>the</strong>y were also cultivators. Could <strong>the</strong>y represent a<br />
pastoral sub-group <strong>of</strong> a Dhar <strong>Tichitt</strong> cultural complex? Or, were <strong>the</strong>y true agro-pastoralists for whom<br />
<strong>the</strong> Merna was only a grazing <strong>and</strong> shallow-water fishing stop on an elaborate seasonal round? We do<br />
not yet know.

That <strong>the</strong>re was movement between <strong>the</strong> Merna <strong>and</strong> <strong>Tichitt</strong>-<strong>Walata</strong> is evidenced by imported<br />
stone materials <strong>of</strong> Phthanite, Amazonite <strong>and</strong> Jasper from Mauritania. Indeed, it is possible that<br />
Ndondi Tossokel <strong>and</strong> Kobadi trade contact long predates <strong>the</strong> first arrival <strong>of</strong> <strong>the</strong> former's settlements<br />
in <strong>the</strong> region. Above all, trade could have been in <strong>the</strong> form <strong>of</strong> commodities: rare stones <strong>and</strong> cattle for<br />
fish <strong>and</strong> possibly grain.<br />
Around 1300 BC it would also appear that <strong>the</strong> Kobadi tradition underwent a shift, with <strong>the</strong><br />
appearance <strong>of</strong> Ben5touma ware. This may simply represent a later phase <strong>of</strong> <strong>the</strong> Kobadi tradition, but<br />
it is notable that Beretouma ceramics occur frequently on sites where Kobadi <strong>and</strong> Ndondi-Tossokel<br />
ceramics co-exist. Is it possible that <strong>the</strong> Beretouma tradition might instead be a product <strong>of</strong> contact<br />
between <strong>the</strong>se two groups? In some cases <strong>the</strong> two populations appear to have lived side by side, or<br />
at <strong>the</strong> very least <strong>the</strong>re was a seasonal trade between <strong>the</strong>m.<br />
Evidence to support this assertion comes from <strong>the</strong> pastoral element <strong>of</strong> <strong>the</strong> Ndondi Tossokel<br />
economy. If <strong>the</strong> cattle had not yet developed tsetse resistance, a substantial seasonal displacement to<br />
<strong>the</strong> north would have been essential for <strong>the</strong>ir herds survival, <strong>and</strong> would have constituted a barrier to<br />
any southward penetration <strong>of</strong> <strong>the</strong> zone (Smith 1979). Even if <strong>the</strong>ir livestock were tsetse resistant, it<br />
would have been difficult for <strong>the</strong>m to have survived in a floodplain environment during <strong>the</strong> wet<br />
season if only for reasons <strong>of</strong> space <strong>and</strong> ho<strong>of</strong>-rot. In any event, <strong>the</strong>ir displacements need not have<br />
been <strong>the</strong> vast migrations practised by modern pastoral groups. Wet season settlements could even<br />
have been located less than 50 km away, at <strong>the</strong> Mauritanian s<strong>and</strong>stone inselbergs <strong>of</strong> which Saberi<br />
Faita is <strong>the</strong> sou<strong>the</strong>rnmost. Questions <strong>of</strong> this nature will remain unanswerable until work is continued<br />
in <strong>the</strong> Merna, <strong>and</strong> survey is conducted in <strong>the</strong> adj9ining Dhar Nema region.<br />
