Decay of Limestone Statues at Mount Nemrut (Adiyaman,Turkey)

Mount Nemrut is a 2,206 m high mountain located in Adiyaman, Turkey. A number of monumental statues, a 50-m high tumulus, and a lion horoscope were constructed at the top of the mountain by King Antiochos I (69–36 bc) of the Commagene Kingdom. The site was included in the UNESCO World Heritage List in 1987 due to its unique character. However, the limestone statues located on both the east and the west terraces of the site are getting deteriorated. This study investigates the weathering of the limestone at Mount Nemrut based on field and laboratory studies. It is found that the dissolution occurs along microcracks developed in the limestone during geological time. It is more pronounced in the east terrace where freezing-thawing cycles are more than the west terrace. Furthermore, dissolution is more effective for the faces of the statues exposed to direct atmospheric contact. Due to harsh atmospheric conditions with dominant wetting-drying and freezing-thawing processes at the site, it is recommended that direct rain and snow contact with the statues should be minimized.     

Life and Death in Neolithic Southeastern Italy: The Strontium Isotopic Evidence

There is a strong relation between people's structured identities and their chemical biographies: these can reflect the way individuals choose to reside and/or move. The strontium isotope ratio (⁸⁷Sr/⁸⁶Sr) of skeletal remains is considered a useful proxy to assess residential mobility and social practices in past populations; however, so far, it has only occasionally been applied to prehistoric contexts in the Mediterranean. In this paper, we present ⁸⁷Sr/⁸⁶Sr data of human and animal samples from several Neolithic sites in the Apulian Tavoliere (southeastern Italy), namely, Grotta Scaloria, Passo di Corvo, Masseria Candelaro and La Torretta/Poggio Imperiale. Data obtained from dental enamel reflect the local origin of the individuals and allowed us to differentiate function and meaning of the sites examined. In particular, within a generally homogeneous background of Sr signatures, the range of ⁸⁷Sr/⁸⁶Sr at Scaloria Cave is greater than at the other sites, with variation likely to be related to funerary practices. We interpret this as the evidence of the ritual use of the cave, which implied the gathering of people of different origin. The relative variation of the Sr signature among individuals, either intersite or intrasite can be tentatively associated with mobility during life as well as with social practices, such as access to foods from geologically different environments.

Isotopic Reconstruction of the Late Longshan Period (ca. 4200–3900 BP) Dietary Complexity before the Onset of State‐Level Societies at the Wadian Site in the Ying River Valley,Central Plains,China

During the late Longshan period (ca. 4200–3900 BP) settlements on the Central Plains of China underwent a diversification in food production technologies, which set the stage for rapid economic and social development. The introduction of novel domesticates such as rice, wheat, cattle, and sheep not only provided more food choices, but also changed ideas concerning land use, farming techniques, and the use and mobilization of large scale labor forces. To better understand the contribution that these new dietary items and practices made to shaping the late Longshan period societies, a stable isotope ratio study of humans (n = 12) and animals (n = 42) was conducted at the late Longshan period site of Wadian. The human δ¹³C and δ¹⁵N values are clustered into two distinct groups. One group of nine individuals (δ¹³C = −9.9 ± 0.7‰; δ¹⁵N = 7.5 ± 0.5‰) had a predominately C₄ diet based on millet grains with little protein input from the domestic animals. The other group of three individuals (δ¹³C = −14.3 ± 0.8‰; δ¹⁵N = 10.2 ± 0.3‰) had a mixed C₃/C₄ diet of millets and rice and were consuming sheep and cattle. The animals also displayed dietary diversity with the pigs (δ¹³C = −11.3 ± 2.5‰; δ¹⁵N = 6.9 ± 1.0‰, n = 10) and dogs (δ¹³C = −10.1 ± 1.0‰; δ¹⁵N = 7.2 ± 1.1‰, n = 7) having mostly a C₄ plant based diet (millets). In contrast, the cattle (δ¹³C = −12.8 ± 2.1‰; δ¹⁵N = 7.6 ± 0.7‰, n = 9), sheep (δ¹³C = −16.7 ± 0.9‰; δ¹⁵N = 7.6 ± 0.1‰, n = 2), and cervids (δ¹³C = −20.8 ± 0.9‰; δ¹⁵N = 5.0 ± 1.2‰, n = 10) had diets with a greater contribution from C₃ sources such as rice and wild plants. The discovery that humans and animals had different subsistence patterns indicates dietary complexity at Wadian and that rice agriculture, and cattle and sheep husbandry practices were already an important part of the local economy by the late Longshan period in the southern region of the Central Plains of China.

A Correction and Comment on ‘Sacrifice of the Social Outcasts’

C. L. Kieffer incorrectly identified a fused pair of cervical vertebrae in an article published online in May of 2015. This is a correction of the misidentification and a comment on the implications for the author's larger point that the individuals involved may have been physically handicapped and therefore selected by the ancient Maya as victims of human sacrifice.

New Finds from the Cremains in Tomb II at Aegae Point to Philip II and a Scythian Princess

Earlier osteoarchaeological studies on cremains of the two individuals from Tomb II at Aegae led to endless debates on the identity of the dead. After re‐examining the bones with Computerized Tomography (or CAT scan) (CT) and X‐Ray Fluorescent scanning (XRF) support, our research team has found new evidence identifying the dead man in the main chamber as Philip II and the woman in the antechamber as the daughter of King Atheas killed in a battle against Philip II in 339BC.

A Hellenistic/Early Roman Shipwreck Assemblage off Ashkelon, Israel

Underwater surveys at Ashkelon during 1998 exposed a Hellenistic/Roman shipwreck. The ship, c .15–25 m long, sank in the 1st or 2nd century BC, and its remains include iron anchors, lead sheathing, copper nails, assorted metal artefacts, and shipwright's unused nails. Bronze vessels found—oil-lamp, shovel and ladles—could have functioned in cult rites. Weights and balance-scale parts demonstrate commercial activity. Fishing-net sinkers indicate involvement in fishing. This paper raises important points regarding the risk to shipwrecks on the Israeli coast from environmental and human interference, and suggests that Ashkelon never had a built-up port.

Porotic hyperostosis in a Late Upper Palaeolithic skeleton (Villabruna 1, Italy)

Porotic hyperostosis (PH) is a well‐recognised skeletal indicator of physiological stress occurring during the early years of childhood growth. Although frequently found starting from the Neolithic, PH is poorly documented among earlier Palaeolithic hunter–gatherers. This study reports a case of PH in a Late Upper Palaeolithic skeleton (Villabruna 1) from northern Italy. Macroscopic and radiographic examinations of the skeleton show symmetric porotic lesions of the cranial vault, hair‐on‐end appearance, thinning of the cortical bone, diploic expansion and very slight cribra orbitalia (CO). All lesions are highly remodelled and suggest a condition suffered long before death. A differential diagnosis, carried out in order to discriminate between infectious and acquired conditions, points to anaemia as likely aetiology for the changes observed. Absence of postcranial involvement, lesion healing and survival to adulthood suggest a diagnosis of acquired anaemia. Among acquired anaemias, both dietary and infectious models are discussed in light of the individual's skeletal characteristics, as well as geographic location, paleoenvironmental data, subsistence modality and dietary information. The combined analysis of these data suggests that parasitic infestation resulted in megaloblastic anaemia in this individual. Copyright © 2009 John Wiley & Sons, Ltd.     

Downward hydrocarbon migration predicted from numerical modeling of fluid overpressure in the Paleozoic Anticosti Basin,eastern Canada

The Anticosti Basin is a large Paleozoic basin in eastern Canada where potential source and reservoir rocks have been identified but no economic hydrocarbon reservoirs have been found. Potential source rocks of the Upper Ordovician Macasty Formation overlie carbonates of the Middle Ordovician Mingan Formation, which are underlain by dolostones of the Lower Ordovician Romaine Formation. These carbonates have been subjected to dissolution and dolomitization and are potential hydrocarbon reservoirs. Numerical simulations of fluid‐overpressure development related to sediment compaction and hydrocarbon generation were carried out to investigate whether hydrocarbons generated in the Macasty Formation could migrate downward into the underlying Mingan and Romaine formations. The modeling results indicate that, in the central part of the basin, maximum fluid overpressures developed above the Macasty Formation due to rapid sedimentation. This overpressured core dissipated gradually with time, but the overpressure pattern (i.e. maximum overpressure above source rock) was maintained during the generation of oil and gas. The downward impelling force associated with fluid‐overpressure gradients in the central part of the basin was stronger than the buoyancy force for oil, whereas the buoyancy force for gas and for oil generated in the later stage of the basin is stronger than the overpressure‐related force. Based on these results, it is proposed that oil generated from the Macasty Formation in the central part of the basin first moved downward into the Mingan and Romaine formations, and then migrated laterally up‐dip toward the basin margin, whereas gas throughout the basin and oil generated in the northern part of the basin generally moved upward. Consequently, gas reservoirs are predicted to occur in the upper part of the basin, whereas oil reservoirs are more likely to be found in the strata below the source rocks.
