Processes behind the shift from hunting-gathering to food production lifestyle are multifaceted and not yet completely understood. The Mediterranean
coast of NW Africa provides an eclectic transitional pattern, namely, a very hesitant transition to food production. The distribution and abundance of
early Neolithic domesticated species is disparate and region specific. Climate and environmental change have been often considered as an important
influencing factor for this transition. This hypothesis was tested using archeological shells of the rocky intertidal gastropod Phorcus turbinatus recovered
from the Ifri Oudadane site in NE Morocco. The oxygen isotope composition (δ18O) of the shell was used to examine whether the hesitant transition to
food production was linked to a local climate shift in the Mediterranean Maghreb. Intrashell δ18O values suggest a marked temperature increase from >7.6
to ~7.0 cal. ka BP, the time when Neolithic innovations first appear on site. An additional increase in temperature from ~7.0 to <6.8 cal. ka BP matches
with the beginning of the main occupation phase and the doubtless breakthrough of cultivation at Ifri Oudadane. This apparent warming trend, although
considered preliminary, seems to match well with warming tendency observed in several published regional climate proxies. Therefore, a temperature
shift may have played a role in the timing and implementation of food production in the area. Last growth episode δ18O values suggest that shellfish were
harvested throughout most of the year, with noticeable intensification during the cooler half of the year. This preliminary pattern was fairly consistent
throughout the Epipaleolithic and early Neolithic phases, pointing to a probable near year-round site occupation rather than a single season settlement.
Future research on Ifri Oudadane and other NW African archeological records are much needed to assess whether these patterns persist in Morocco
and other Epipaleolithic and early Neolithic settlements in the western Mediterranean Maghreb.

This paper deals with general trends of the Moroccan Neolithic: chronological framework, external influences and environmental impact. Particular focus is on the end of the 7th millennium calBP when a supposed Middle Neolithic should start. However, the paper shows that apparently no distinct chrono-cultural unit between Early and Late Neolithic is detectable, wherefore term and concept of a Middle Neolithic
should be abandoned. The Neolithic transition of Mediterranean Morocco itself is an integral part of the Neolithisation process within
the Western Mediterranean as a whole. Neolithic innovations enter the Alboran territory via the range of the Ligurian Early Neolithic. Between the Southern Iberian Peninsula and Northwest Africa these innovations became distributed through Epipalaeolithic coastal networks, here called “Coastal Epipalaeolithic”. In the following, coastal groups start food production (“Early Neolithic”), depending on local environmental
conditions on a very different scale. Cultivation and animal husbandry remained only one aspect of subsistence in the sense of a broad spectrum economy or low level food production. Through continental networks local foragers occupying the West-Mediterranean hinterlands (“Continental Epipalaeolithic”) adopt Neolithic inventions such as pottery
and integrate them step by step in their way of life. Because food production is not yet recorded during the Early Neolithic period, these groups afterwards are called “Epipalaeolithic in Transition”.
Furthermore, the impact of climate and environmental change on cultural changes shall be evaluated. While the Neolithisation itself until now seems to have been triggered by socio-economic factors, the end of the Early Neolithic at 6.3 ka calBP, the enforced Saharan impact during the Late Neolithic from 6.0 ka calBP onwards and the end of the Neolithic as a whole at about 4.2 ka calBP correspond closely to
supra-regional climate and environmental changes well documented
in marine and terrestrial archives.

This paper provides a summary of all available numerical ages from contexts of the Moroccan Middle Palaeolithic to Epipalaeolithic and reviews some of the most important sites. Particular attention is paid to the so-called " Aterian " , albeit those so-labeled assemblages fail to show any geographical and chronological pattern. For this reason, this phenomenon should not be considered a distinct culture or techno-complex and is referred to hereinafter as Middle Palaeolithic of Aterian type. Whereas anatomical modern humans (AMH) are present in Northwest Africa from about 160 ka onwards, according to current research some Middle Palaeolithic inventories are more than 200 ka. This confirms that, for this period it is impossible to link human forms with artifact material. Perforated shell beads with traces of ochre documented from 80 ka onwards certainly suggest changes in human behavior. The transition from Middle to Upper Palaeolithic, here termed Early Upper Palaeolithic e at between 30 and 20 ka e remains the most enigmatic era. However, the still scarce data from this period requires careful and fundamental revision in the frame of any future research. By integrating environmental data in reconstruction of population dynamics, clear correlations become obvious. High resolution data are lacking before 20 ka, and at some sites this period is characterized by the occurrence of sterile layers between Middle Palaeolithic deposits, possibly indicative of shifts in human population. After Heinrich Event 1, there is an enormous increase of data due to the prominent Late Iberomaurusian deposits that contrast strongly from the foregoing accumulations in terms of sedimentological features, fauna and artifact composition. The Younger Dryas shows a remarkable decline of data marking the end of the Palaeolithic. Environmental improvements in the Holocene are associated with an extensive Epipalaeolithic occupation.

Since 1995 archaeological research has been undertaken in the Eastern Rif (Morocco) by a Moroccan-German research team with participation of the “Institut National des Sciences de l’Archéologie et du Patrimoine du Maroc” (INSAP), the “Kommission für die Archäologie Außereuropäischer Kulturen des Deutschen Archäologischen Instituts” (KAAK), and the Institute of Prehistoric Archaeology of the University of Cologne. In the course of these studies, several hundred sites have been discovered and a number of these excavated. Sites investigated in more detail cover the time span from the Lower Palaeolithic up to Islamic times. From the onset of the project a particular focus has been on Neolithisation processes in the area. In the last years the raw material supply for pottery and stone tool production has also come into focus. In cooperation with mineralogists and sedimentologists a number of raw material sources could be identified. This paper summarises all known Neolithic sites and pot...

The Lower Moulouya Basin in northeast Morocco is characterised by Mediterranean arid to semiarid environmental conditions of a North African desert margin. In geomorphological research, desert margins reveal a high potential for palaeoenvironmental studies, as they react very sensitive to past and future climatic changes. The alluvial deposits of the Lower Moulouya can be divided in three sedimentation series: the Series I is dated between 9.9 and 6.5 ka cal. BP and shows silty to sandy layers with hydromorphic features and intercalated initial alluvial soils. The Series II is dated between 4.2 and 3.2 ka cal. BP and indicates clayey to silty fine laminae with hydromorphic features and an onset of charcoal-rich layers. The Series III is dated between 3.2 and 1.4 ka cal. BP and features clayey to silty fine laminae with greyish to reddish colouring. Series III reveals charcoal-rich layers and gypsum crystals in clay-rich reddish sediments. The dating of the archaeological findings (s...

ABSTRACT The densely populated, low-lying Ganges-Brahmaputra Delta is highly vulnerable to global sea-level rise. In order to estimate the rate of subsidence of the delta, we examined submerged salt-producing kiln sites in the coastal Sundarbans (a huge UNESCO-protected mangrove forest). These kilns were built just above the winterly spring high-tide level of the time, but their bases are currently located ~155 cm below the corresponding modern level. According to optically stimulated luminescence (OSL) dating, the kilns were last fi red ~300 yr ago, and salt production was terminated by a catastrophic event that affected the kiln sites at different levels and locations. 14C ages of charcoal at the kilns’ bases and associated mangrove stump horizons support the OSL dates. Based on the elevations and ages, the 300 yr average rate of sinking of the outer delta is 5.2 ± 1.2 mm/yr, which includes 0.8 mm/yr of eustatic sea-level rise. With the expectation of further acceleration of sea-level rise, the already-present problematic situation will be aggravated, and only prudent control of sediment accretion will keep southern Bangladesh above sea level.

This paper presents the Early and Late Neolithic pottery of Ifri Oudadane, a littoral shelter in Northeast Morocco containing both Epipalaeolithic as well as Neolithic deposits. The transition is indicated by the appearance of domesticated plant and animal species, pottery and diverse changes in lithic technology. A domesticated lentil dated to 7.6 ka cal BP may mark the onset of this transitional process. With the help of 22 14C-ages the Early Neolithic deposit can be subdivided in three phases (ENA, ENB, ENC). In addition, the ENC phase contained the remains of a sporadic Late Neolithic occupation. Pottery decoration of the initial ENA phase (7.6–7.3 ka cal BP) is dominated by single Cardium impressions forming horizontal and vertical bands of impressions arranged vertical, horizontal or oblique. The successive ENB phase represents the main occupation phase between 7.1 and 6.6 ka cal BP. By means of statistical methods its assemblage, which consists of 243 vessel units, could be further subdivided (ENB1, ENB2). While ENB1 (7.1–6.9 ka cal BP) is still characterised by single Cardium impressions, the transition to ENB2 is marked by the appearance of Cardium and, later, comb impressions made using rocker stamp technique as well as a few impressions of points and spatulas, striations and modelled applications. Thus the pottery assemblage of Ifri Oudadane offers insights into the first occurrence of pottery in Mediterranean Northwest Africa and opens up the possibility for an internal classification of the Early Neolithic.

The littoral site of Ifri Oudadane is one of the most important recently excavated sites in the Mediterranean Maghreb. The shelter presents Epipalaeolithic and Neolithic layers and therefore offers the possibility to investigate the Neolithic transition in the region. Besides introducing the archaeological
context, this paper focuses on palaeobotanical data in order to reconstruct Holocene environmental change and human use of plant resources for the period c. 11 to 5.7 ka cal. BP. Results show intense landscape transformations resulting from anthropic and climatic factors. First human occupations start at the beginning of the Holocene with favourable conditions in this otherwise harsh semi-arid stretch of land. A wooded environment with evergreen sclerophyllous oaks and riparian forests is documented and exploited by hunter-gatherers. From c. 7.6 ka cal. BP farming activities are well attested together with significant human impact, herding pressure and a progressive decline of arboreal components. After 6.6 ka cal. BP conditions become less favourable and markers for aridity increase. Riparian taxa disappear (Alnus) or decrease (Fraxinus, Populus, Salix); shrubs (Tamarix) and grasses (Artemisia) increase with a degradation of forest into shrubland (macchia). During 6.6 and 6.0 ka cal. BP there is a general occupation gap in arid and semi-arid Morocco and evidence for that change is also found in the alluvial deposits of the Moulouya, NE Morocco. Indicators for food production decrease at the same time and the site is abandoned during the first half of the 6th millennium cal. BP.

The cultural sequence of the Late Pleistocene and Early Holocene of Morocco displays three main techno-complexes: a Middle Palaeolithic, including a special facies called Aterian; an Upper Palaeolithic, separated into an early phase of uncertain
configuration; a later phase, termed Iberomaurusian; and an Epipalaeolithic (Linstädter et al. 2012). The more or less homogeneous appearance of the Middle Palaeolithic in Southern Europe, the Near East and Northern Africa suggests a permeable circum-Mediterranean complex where late Pleistocene humans shared common lithic technologies. Admixture of Neanderthal genes with the gene pool of anatomic modern humans suggests that these humans in Africa and Europe belong to the same species and morphological differences must be classified to the subspecies
level only. Interstratifications of Middle Palaeolithic and Atérien levels indicate that tanged points only are not a sufficient marker to define a proper culture or techno-complex. The Aterian should therefore not be treated as an independent
cultural complex. The most enigmatic period in northern Africa is the transitional phase from the Middle to the Upper Palaeolithic. Sites and well defined assemblages from this
period are extremely rare. The character of human occupation and the accompanying technology during this time remains ambiguous. This crude and basically still unknown Early Upper Palaeolithic ends with the appearance of the Iberomaurusian.
It represents the best defined Palaeolithic culture of north-western Africa. In our terminology the Iberomaurusian is followed by an Epipalaeolithic that commences
around the Pleistocene Holocene boundary.
Detailed analysis of 191 available radiometric data in combination with stratigrafical evidence from multilayered sites gives insight into human settlement pattern
at various stages of the cultural sequence. Some 25 sites from Morocco provide evidence for the analysis.

Four samples were dated by luminescence in the Cologne Luminescence Laboratory (CLL) to provide information on the geochronological context
of an earth oven exposed on a tidal flat close to Katka in the south eastern Sundarbans, Bangladesh. Optically stimulated luminescence (OSL) on
quartz was used to determine the last heating of the oven walls to more than 400 °C. This temperature is assumed to thermally erase the natural
luminescence signal of the sediments and to reset the luminescence clock to zero. Samples were taken from the oven walls using metal cylinders
and then prepared for OSL quartz measurements. Two different grain sizes (4-11 and 40-63 μm) were prepared to elaborate the influence of the
thermal resetting to the signal intensities and the precision of the equivalent dose (De) determination.

Archaeological layers of palaeolithic rockshelteres often represent
palimpsests. Their buildup involves phases of enhanced
sediment accumulation during occupation and strongly
reduced sediment accumulation during abandonment of the
site. Partial sediment erosion by anthropogenic or natural
processes may lead to loss of strata. Renewed occupation of
a site may then take place on old surfaces related with the
last, penultimate or even older occupations. Mixing of sediment
and archaeological materials by bioturbation, cryoturbation,
peloturbation or processes of mass movement along a
slope results in formation of cumulative palimpsests (e.g.,
Bailey 2007). Humans cause mixing by differential trampling,
raking out of fire residues and levelling of dwelling floors. All
