Scientific Analysis and Conservation of Waterlogged Woods Excavated from Suyoeng-ri Site, Hwaseong, Korea

Five waterlogged wood artefacts were excavated from Suyeong-ri site in Hwaseong, South Korea. The aim of the present study was to identify the species and estimate the date of manufacture and the manufacturing method of these artefacts. The study also aimed to conserve the original shapes of waterlogged wood artefacts by using the vacuum freeze drying method. The two large waterlogged woods were identified as Ulmus spp. and Morus spp., whereas one of the three small waterlogged woods was identified as Abies spp. and the other two as hard pine. Radiocarbon dating using wiggle match dated the manufacturing of these wooden artefacts between BCE 8520-8490 or BCE 8470-8290 in the Neolithic age, and a similar period was also confirmed for seed excavated from a place close to the location where the waterlogged wood artefacts were excavated. The surface of waterlogged wood artefacts had several traces of manufacturing processes - traces of tearing and chopping - were observed. Based on these observations, it was confirmed that stone adz was used to make these wooden artefacts. Thereafter, the waterlogged wood samples were conserved by immersing them into PEG#4,000 of concentration in water from 10% to 40% at room temperature(15~25℃) and subjecting them to vacuum freeze drying. However, the internal moisture was not completely removed in some thick parts of waterlogged woods by applying the general schedule such as raising the shelf temperature as the surface temperature rises. Therefore, additional study is required using the schedule-method for vacuum freeze drying of large waterlogged wood.

Study on Scientific Analysis about Red Pigment And Binder - The Korean Ancient Red Pottery -

From the collection of the National Kimhae Museum, qualitative analyses using microscopic observation, SEM-EDS, Raman spectroscopy, FT-IR-ATR spectroscopy, and GC-MS were conducted on three burnished red potteries—Jeoksaekmaoyeonwa burnished red pottery (Neolithic age red pottery), Dandomaoyeonwan burnished red pottery(Bronze age red pottery) and Jeoksaekmaoyeongajimun burnished red pottery(Bronze age red pottery)—to investigate the components of the red pigments and the binder. After the layers of the primer were separated from the red surface, crystals of red pigment particles and minerals were found on the red surface. Through SEM-EDS, Raman estimates that the red pigment is Among soil pigments with iron oxide(Fe2O3) as the main color development source, Red Ocher(Fe2O3). A band characteristic of the Urushiol polymer was detected in the FTIR-ATRspectra(4000∼600cm-1), GC-MS analysis confirmed the presence of the benzenemethanol-2-prophenyl, 4-heptylphenol, 1-tetracecanol, heptafluorobutyric texidecane, all of which are the ingredients of the directional structure of the lacquer present in the red layer. Therefore, it seemed that the three burnished red pottery: Jeoksaekmaoyeonwan pottery(Neolithic age burnished red pottery), Dandomaoyeonwan pottery(bronze age burnished red pottery) and the Jeoksaekmaoyeongajimun pottery(bronze age burnished red pottery) made by mixing minerals and Red Ocher(Fe2O3), with lacquer.

Revisiting the 5000-Year-Old Tally at Mnajdra, Malta

The pillars at the entrance of the inner apse of one of the cluster of Neolithic temples at Mnajdra, Malta display rows of drilled holes which have been interpreted as a tally of days. Furthermore, it has been proposed that the number of holes in the rows on the east pillar coincides well with a sequence of intervals between the heliacal rising of bright stars or star groups. Is this remarkable correspondence simply a chance occurrence, or do the drilled holes represent material evidence of deliberate time reckoning by means of heliacal star risings in the Neolithic age? This question has led to the statistical investigation described in this paper, which takes into account the heliacal risings of all stars of magnitude 2.0 or brighter visible from Malta 5000 years ago as well as the Pleiades and the Hyades star clusters, which attracted the attention of other ancient cultures. The paper presents and discusses the method used and the challenges involved in the investigation. The results show that with a tolerance of ±1 day for uncertainty in the calculated heliacal rise days, the probability of achieving an exact correspondence between a random ordering of the tally and a series of star rises is 0.0014. With a wider tolerance of ±2 days the probability is 0.011. The final section discusses the significance and implications of these results.

Millet arrived in the South China Coast around 5,500 years ago

<p>Crop dispersal has long been recognised as an important topic in agricultural archaeology and food globalisation. One of most pressing questions facing archaeologists is determining when and where millet arrived in the South China Coast. Our study focused on the millet phytoliths remains from three Neolithic sites in southeast coastal Fujian. Multiple dating methods, including charred carbon dating, phytolith carbon dating, and optically stimulated luminescence were used to construct the chronologies of the sites. The dating results showed that BTS was initially occupied at approximately 5,500 cal a BP. The millet phytoliths recovered in this study are likely the earliest millet remains found in Fujian, suggesting that millet arrived in the South China Coast at least 5,500 years ago. However, questions about whether millet agriculture in northern China dispersed southward through the inland or coastal routes remain unanswered. Given that millet remains were found in Jiangxi and northern Fujian – two important gaps in the inland route – no earlier than 5,000 cal a BP, it seems that the millet remains recovered from the coastal sites of Fujian might have dispersed following a coastal route from northern China. Nevertheless, Fujian is an important junction of the coastal route for the dispersal of millet from northern China. These findings not only provide new insights to millet dispersal routes in China, but also have significant implications for crop communications between Taiwan and mainland China during the Neolithic age.</p><p> </p><p> </p>

Morpho-Agronomical and Nutritional Evaluation of Cultivated Einkorn Wheat (Triticum monococcum L. ssp. monococcum) Lines Sown in Autumn and Spring Seasons

Nowadays diploid einkorn wheat (Triticum monococcum L. ssp. monococcum), widely cultivated in the Neolithic age, has been reconsidered as the valuable genetic resource for breeding and organic farming due to its high resistance to pests and diseases, adaptation to harsh climates, ability to provide acceptable yields on poor soils even with low/without inputs and high nutritional values. In this research, local 45 cultivated einkorn lines, selected from 500 single rows planted by each single spikes collected from total 50 farmers’ fields in 34 villages of Kastamonu/Turkey, were evaluated in terms of their morpho-agronomical traits and nutritional characteristics during two sowing seasons, autumn 2017 and spring 2018. Einkorn lines sown in two different seasons showed significant variations for heading time, plant height, lodging susceptibility, spike length, number of spikelets per spike, gross grain yield, amount of glume, single kernel weight, kernel diameter, hardness index, grain protein content and the color (a, b, L) values of flour. Furthermore, most of the correlation coefficients between these characteristics were found to be significant. All lines showed “facultative” growth habit, flowering well when sown both in autumn and in spring. Although lines sown in autumn had more yields, the same lines sown in spring provided higher grain quality and more resistance to lodging due to having shorter stems. In order to enable sustainable future use of einkorn, further research is suggested for reduction of plant height to avoid lodging and improvement of grain yield to compete with modern high yielding wheat cultivars.

Different Human–Dog Interactions in Early Agricultural Societies of China, Revealed by Coprolite

Dogs served in a variety of capacities in prehistory. After their domestication in Paleolithic hunter-gatherer societies, the emergence of agriculture shifted their partnerships with people. However, the associations between dogs and early farmers are not readily visible in the archaeological record. In the present study, dog coprolites, uncovered from two groups of early agricultural societies in China during the Neolithic Age, the early rice agricultural site of Tianluoshan in the lower Yangtze River, and three early millet-rice mixed agricultural sites of Shuangdun, Yuhuicun, and Houtieying along the middle Huai River, were examined based on the comparisons of lipid and palynological results to reveal different relationships of dogs and humans. The Tianluoshan dogs showed a plant-dominated diet with higher contents of plant sterols and fatty alcohols with longer chain lengths. Dogs may have lived on foraging or been provisioned with refuse for the cleanness purpose. On the contrary, dogs from the sites of Shuangdun, Yuhuicun, and Houtieying showed a meat-dominated diet with higher proportions of animal sterols and short-chain fatty alcohols. It most probably referred to their assistance in hunting and thus being provisioned with meat. Furthermore, activity areas of the dogs also reflect different deployment strategies and agricultural systems, evidenced by pollen spectra from the coprolites. Dogs at Tianluoshan mostly appeared in the rice field area, in correspondence with the labor-consuming rice cultivation as the main targeted resource, showing their participation in daily agricultural activities. On the other hand, high concentrations of pollen from forest and grassland revealed that hunting dogs played a regular role in the early millet-rice mixed farming societies, probably related to the importance of hunting activities in the daily subsistence.
