Early Holocene ritual complexity in South America: the archaeological record of Lapa do Santo (east-central Brazil)
2016
Early Archaic human skeletal remains found in a burial context in Lapa do Santo in east-central Brazil provide a rare glimpse into the lives of hunter-gatherer communities in South America, including their rituals for dealing with the dead. These included the reduction of the body by means of mutilation, defleshing, tooth removal, exposure to fire and possibly cannibalism, followed by the secondary burial of the remains according to strict rules. In a later period, pits were filled with disarticulated bones of a single individual without signs of body manipulation, demonstrating that the region was inhabited by dynamic groups in constant transformation over a period of centuries.
Dating Bulk Sediments from Limnic Deposits Using a Grain-Size Approach
2013
Radiocarbon measurements on bulk subaqueous sediments typically provide ages significantly older than actual time of deposition. This is generally caused by the presence of reworked organic compounds, which are depleted in 14C. To explore this issue of age heterogeneity, we collected 4 organic-rich samples from varying depths in a lake sediment core at the Gemündener Maar (Eifel, Germany), a lake of volcanic origin. We divided each sample into 5 standard grain-size fractions: gravel, sand, silt, clay, and 1 fraction smaller than 0.45 μm. These were cleaned separately using a standard acid-alkali-acid treatment. The highly organic gravel-size fraction provided the youngest 14C ages of all gr…
Analysis of Cipollino Verde marble wall decoration in Ephesos, Turkey, using geological reconstruction
2021
Abstract Slabs of Cipollino Verde, composed of layered and folded marble from Euboea in Greece, decorated the hall of a Roman town house in Ephesos, Turkey in the second century AD. After excavation, the fragmented slabs were restored. Preservation of the dowels in the walls from which the slabs were originally suspended allowed reconstruction of the order in which they had been placed on the walls. The pattern of folded layering in the slabs in turn allowed 3D structural geological reconstruction of the folds, and reconstruction of the arrangement of slabs in the marble block, from where they were serially sectioned, using a slab saw. Investigation of geological fold alignment in the block…
Interpreting the Schöningen 13II-4 butchery sequence using the Harris Matrix
2021
Abstract The Schoningen 13II-4 site is well known for the discovery of multiple wooden spears in association with a large assemblage of Middle Pleistocene fauna. Such extraordinary organic preservation also extends to a wide array of bone surface modifications that can be used to reconstruct Middle Pleistocene hominin butchery practices. On bones with few hominin-induced marks, the butchery sequence can be determined quite easily. However, the sequence becomes increasingly more difficult to decipher in bones that include a high number and diversity of biotic and abiotic modifications. To aid in this process, we developed a simple approach for determining the order of bone surface modificati…
Dietary freshwater reservoir effects and the radiocarbon ages of prehistoric human bones from Zvejnieki, Latvia
2016
Abstract Aquatic food resources (fish and molluscs) were exploited intensively at Riņņukalns, a Neolithic freshwater shell midden at the outlet of Lake Burtnieks, north-eastern Latvia. Stable isotope data (δ 15 N and δ 13 C) from a rich fishbone assemblage and a wide range of terrestrial species complement published results on faunal samples from the famous prehistoric cemetery and settlement at Zvejnieki, on the same lake. Stable isotope data show that freshwater food resources made substantial but varying contributions to human diets at Zvejnieki and Riņņukalns throughout the Mesolithic and Neolithic. Our research has also shown significant radiocarbon freshwater reservoir effects (FRE) i…
Potential Freshwater Reservoir Effects in a Neolithic Shell Midden at Riņņkalns, Latvia
2014
Riņņukalns is the only known prehistoric shell midden in the eastern Baltic, and is one of the few middens in northern Europe consisting mainly of freshwater mussel shells. Situated on the Salaca River at the outlet of Lake Burtnieks, in northeastern Latvia, the site was originally excavated in the 1870s, and reinvestigated several times over the following decades. A new excavation in 2011 showed that part of the midden remained intact. The new exposure, dated to the later 4th millennium cal BC, yielded rich fishbone and mollusk shell assemblages, herbivore, human and bird bones, and a wide range of artifacts typical of a subsistence economy based on fishing, hunting, and gathering. Human r…
Priedaine: A Neolithic Site at the Head of the Gulf of Riga
2016
The Neolithic site of Priedaine in Jūrmala was excavated on a small scale in 2007–2008, yielding an assemblage of Comb Ceramics, along with unique wooden implements and fragments of pine-lath fishing structures. The environment and subsistence resources are indicated by plant macrofossil remains and a small faunal collection. Located by a palaeolake and also very close to the sea, the site, dated to c. 3700–3500 cal BC, would have been oriented towards aquatic resource exploitation. However, it had a wider range of functions, as indicated by the evidence of flint and amber processing. Key words: Neolithic, pottery, fishing gear, plant macro-remains, faunal remains, lake, coastal settlement.…
Earliest salt working in the world: From excavation to microscopy at the prehistoric sites of Ţolici and Lunca (Romania)
2018
Abstract Since the Early Neolithic, salt has played an important role in the social and economic development of populations. Consequently, the study and comprehension of salt management strategies have become a significant component of current archaeological research. This study is part of an interdisciplinary research program consisting of excavations and detailed analyses on two Early Neolithic salt working sites situated in the sub-Carpathian region of Romania, Lunca and Ţolici (county Neamţ). These remarkably well-preserved sites are characterised by stratified deposits several meters thick. Detailed stratigraphic descriptions were followed by optical microscopy analysis (soil micromorp…
Analysis of the bacterial communities in ancient human bones and burial soil samples: Tracing the impact of environmental bacteria
2019
Abstract In our attempts to reveal the hidden fragments of the history of the natural world, ancient DNA (aDNA) is the precious missing key that allows us to discover hidden truths about ourselves and the world around us. Not only does aDNA encrypt genetic data from a particular individual, it also carries information about the microbial communities that were present in the individual. However, the process of such data mining has many intrinsic challenges. One of the main challenges in aDNA research is the contamination of archaeological material with environmental bacteria from the surrounding soil and postmortem microbial sources. The goal of this study was to identify the microbial commu…
