Human manipulation of terrestrial gastropods in Neolithic culture groups of NE Morocco. doi Spatial

Shells of terrestrial gastropods (Helicidae, Sphincterochilidae) are common in rock shelter sediments and open-air sites of Iberomaurusian to Neolithic age in NE Morocco. Excavations at numerous sites in the eastern Rif yielded new sites with a rich record of well-preserved terrestrial gastropods, among which species of the genera Otala, Sphincterochila and Alabastrina dominate. In sites with sediments younger than 7500 calBP, such as Taghit Haddouch, Hassi Ouenzga, Ifri Oudadane, Ifri Armas and Mtlili, a...

The Early Neolithic pottery of Ifri Oudadane, NE Morocco. Qualitative and Quantitative evidences. doi Spatial

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,...

The Palaeolithic site Sima de Las Palomas de Teba, Southerrn Spain – Site formation processes and chronostratigraphy Spatial

Abstract (The Palaeolithic site Sima de las Palomas de Teba, Southern Spain Site formation processes and chronostratigraphy: The rockshelter sequence consists of 6 m thick stonerich silty clay loam including several archaeological levels with artefacts of Mousterian affinity, bone and charcoal. Stratigraphy and site formation processes were characterised by sedimentological, geochemical and micromorphological investigations. Sediments were dated using IRSL and OSL and the time of the last heating of burnt...

Black Carbon: fire fingerprints in Pleistocene loess-palaeosol archives in Germany doi Spatial

Past environmental changes were frequently accompanied by changes in fire regimes. However, the extent to which the residue of ancient fires (black carbon, BC) is abundant in Pleistocene palaeosols remains largely unknown, and whether, and to which degree its occurrence and composition relates to pedogenetic processes and palaeoenvironmental change. We studied three Pleistocene loesspalaeosol sequences from western Germany for systematic variation in BC quantity and quality during Marine Isotope Stages 5e...

Holocene environmental change in NE Morocco: Archaeological and Palaeobotanical evidences from Ifri Oudadane Spatial

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...

Sediment sequence and site formation processes at the Arbreda Cave, NE Spain, and implications on human occupation and climate change during the Last Glacial doi Spatial

The cave of Arbreda provides a detailed archaeological record of the Middle to Upper Palaeolithic and is a key site for studying human occupation and cultural transitions in NE Iberia. Recently, studies of lake archives and archaeological sites presented new evidence on climate changes in NE Iberia correlating with Heinrich events. It, therefore, needs to be determined whether climate signals can be identified in the cave sequence of Arbreda, and if so, whether these signals can be correlated with...

Distinct lake level lowstand in Lake Prespa (SE Europe) at the time of the 74 (75) ka Toba eruption doi Spatial

The 74 (75) ka Toba eruption in Sumatra, Indonesia, is considered to be one of the largest volcanic events during the Quaternary. Tephra from the Toba eruption has been found in many terrestrial and marine sedimentary deposits, and acidity peaks related to the eruption have been used to synchronize ice core records from Greenland and Antarctica. Seismic profiles and sedimentological data from Lake Prespa on the Balkan Peninsula, SE Europe, indicate a lake level lowstand at 73.6 7.7 ka based on ESR dating...

Climate variability over the last 92 ka in SW Balkans from analysis of sediments from Lake Prespa Spatial

The transboundary Lake Prespa (Albania/former Yugoslav Republic of Macedonia/Greece) has been recognized as a conservation priority wetland. The high biodiversity encountered in the catchment at present points to the refugial character of this mountainous region in the southwestern Balkans. A lake sediment core retrieved from a coring location in the northern part of the lake was investigated through sedimentological, geochemical, and palynological analyses. Based on tephrochronology, radiocarbon and...

Late Pleistocene and Holocene contourite drift in Lake Prespa (Albania/F.Y.R. of Macedonia/Greece) doi Spatial

Hydro-acoustic surveys and coring campaigns at Lake Prespa were carried out between 2007 and 2009. This paper presents hydro-acoustic profiles and provide lithological and chronostratigraphical information from three up to 15.75 m long sediment sequences from the Macedonian side of the lake. The sediment sequences comprise glacial and interglacial sediments likely deposited from the end of Marine Isotope Stage (MIS) 5 to present day. The information implies a distinct change of sedimentation patterns at the...

Understanding past climatic and hydrological variability in the Mediterranean from Lake Prespa sediment isotope and geochemical record over the Last Glacial cycle doi Spatial

Here we present stable isotope and geochemical data from Lake Prespa (Macedonia/Albania border) over the Last Glacial cycle (Marine Isotope Stages 5-1) and discuss past lake hydrology and climate (TIC, oxygen and carbon isotopes), as well as responses to climate of terrestrial and aquatic vegetation (TOC, Rock Eval pyrolysis, carbon isotopes, pollen). The Lake Prespa sediments broadly fall into 5 zones based on their sedimentology, geochemistry, palynology and the existing chronology. The Glacial sediments...

Out of Africa, the Nile Valley and the Northern Route Spatial

Hypotheses on the dispersal patterns of modern humans out of Africa have undergone much change in the past decade, with new ideas on the routes and geographic extent of movements proposed. New data and perspectives from the Nile Valley necessitate reassessment of the role of the Northern Route. Here, fossil evidence and technological strategies followed in the Nile Valley between 200 000 to 300 000 years ago, and its relevance to dispersal patterns are discussed. Most of the sites in the Nile Valley relate...

Late Neanderthals at Jarama VI (central Iberia)? doi Spatial

Previous geochronological and archaeological studies on the rock shelter Jarama VI suggested a late survival of Neanderthals in central Iberia and the presence of lithic assemblages of Early Upper Paleolithic affinity. New data on granulometry, mineralogical composition, geochemical fingerprints and micromorphology of the sequence corroborate the previous notion that the archaeological units JVI.2.1 to JVI.2.3 are slackwater deposits of superfloods, which did not experience significant post-depositional...
