Age‐at‐death assessment using the os pubis and the auricular surface of the ilium: a test on an identified Asian sample

This paper reviews the results of blind tests of two morphological methods of age‐at‐death estimation. These tests were performed on a known age‐at‐death and sex sample taken from a collection of a Thai population. The first technique is based on the age related changes of the pubic symphysis according to the Suchey‐Brooks system, and the other concerns the metamorphosis of the auricular surface of the ilium elaborated by Lovejoy and colleagues. This is the first time that these methods have been tested on skeletal material from Asia. The results indicate that, for both methods, bias and inaccuracy increase with age and true age tends to be underestimated. As a consequence, age‐at‐death assessment based on these two techniques should be avoided on Asian archaeological series or forensic cases. Copyright © 2004 John Wiley & Sons, Ltd.     

Dietary analysis of Piraino 1, Sicily,Italy: the role of archaeopalynology in forensic science

Pollen from intestinal contents of mummies, backed by macrofloral analysis, provides important clues to diet, medicines, and season of death. Intestinal contents were recovered from the Piraino 1 mummy from the “Sepulcher of the Priests”, Piraino Mother Church, in the province of Messina, Sicily. Using standard palynological methods and pollen concentration technique, we quantified the numbers of pollen grains per gram of coprolite. The pollen spectrum was dominated by Polygalaceae, the Milkwort Family. Polygalaceae pollen is rarely found in archaeological sites. Based on comparison to published keys, we determined that the pollen came from a species of Polygala. Polygala contains species with medicinal value. We found nine other pollen types. Traces of Potamogeton (pondweed) was observed in preliminary scans. Multiple grains of Brassicaceae (mustard family), cereal (cultivated grains), Typha (cattail) and Cheno-am were found. Single grains of Castanea (chestnut), Fabaceae (bean family), Salix (willow), and Solanaceae (tomato family) were found. The preservation of the pollen was poor except for Polygala and the cereal pollen. Brassicaceae and Cheno-am have been part of the natural pollen spectrum in Sicily since ancient times. Cereal grains were consumed with prepared food. Importantly, background arboreal pollen was nearly absent. This indicates that Piraino 1 died during months of low pollination. The absence of olive pollen is important since this plant in Sicily reaches its maximum pollination in May and June and tapers off rapidly by mid-June. Therefore, absence of the key warm season airborne pollen type suggests a post-June death. Macrofossils, especially residue from grape pulp, indicates a death in September to November. His cause of death was likely a result of multiple myeloma. The methodological differences between archaeopalynology and forensic palynology are summarized. We suggest that the palynological methods presented here should be adopted for human remains analysis in forensic palynology.     

The morphological identification of micro-residues on stone tools using light microscopy: progress and difficulties based on blind tests

Fifty-three stone flakes were knapped for a series of four blind tests on replicated flakes with residues derived from the processing of plant and animal products. Some flakes were hafted before use. Tests 1 and 2 were pioneering efforts published in 2004; lessons learned from these early studies shaped the new research reported here and lead to improved methodology and interpretive skills. A high level of accuracy was obtained for test 4. Test 3 showed that the rock type of a tool could influence the ability of the analyst to recognize and interpret residues. Test 4 in the series resulted in the most accurate interpretations because, prior to Test 4, identification difficulties experienced during the first three blind test sessions were addressed by examining many stone tools that had been used for various replicated tasks. The preparatory exercise was particularly useful for resolving issues that had previously caused problems for correctly identifying animal residues. The new work reported here highlights some of the difficulties that can be experienced in the morphological identification of microscopic organic residues, particularly the distinction between animal and plant residues. Some solutions for these problems are suggested.     

Insights into early Holocene hunter-gatherer mobility on the Peruvian Southern Coast from mollusk gathering seasonality

Quebrada de los Burros (QLB) is an early Archaic coastal archaeological site in southern Peru (∼18.1°S) and the most extensively studied in the area for this period. It was occupied from 10 to 6.5 ka by fishermen also practicing hunting and mollusk gathering. Shell growth lines in 116 individuals of the surf clam Mesodesma donacium were studied to determine the month of their death (±2 months). Our results show that, for the whole occupation period, mollusk gathering was a seasonal activity mainly practiced during austral spring and summer. A change occurred between the early and the middle Holocene: the mollusk gathering season in the middle Holocene occurred ∼3 months earlier in the year than in the older levels. This behavior change could have a cultural origin, rather than dictated by the environment for it is associated with changes in the lithic industry. QLB occupants also hunted herbivores in the nearby lomas ecosystems. These plant communities only grow during the fog season from June to December, suggesting that the site was occupied during this season. A comparison of the span of the mollusk gathering season and the lomas season suggests that, at least during the early Holocene, QLB was occupied all the year round. A permanent freshwater source and the proximity of the sea, the lomas, and raw lithic materials, provided ideal conditions for a permanent occupation. This result reveals a strategy based on a seasonal alternation between marine and terrestrial resources exploitation.     

Black Death in the rural cemetery of Saint-Laurent-de-la-Cabrerisse Aude-Languedoc,southern France, 14th century: immunological evidence

An excavation carried out in 2007 in Saint-Laurent-de-la-Cabrerisse (Aude-Languedoc, southern France), revealed a medieval rural cemetery used during the 8th–14th centuries. One hundred and forty nine graves were identified. Amongst those, three burials radiocarbon dated to the 14th century contained the remains of several individuals. No paleotraumatological evidences of violence due to warfare or to a civil massacre were identified in the exhumed skeletons. Therefore, we hypothesized that the simultaneous inhumations could have occurred during the “Black Death” outbreak or during one of its resurgences. A rapid diagnostic test for the detection of Yersinia pestis F1 antigen was applied to the nine putative plague victims to authenticate the cause of their death. Seven of the nine individuals tested from the three graves were positive to Y. pestis F1 antigen. We additionally tested fourteen skeletons from single graves archaeologically dated to the 13th–14th centuries. Four of them were positive to Y. pestis F1 antigen, thus showing a higher mortality rate due to plague than originally expected. The Saint-Laurent-de-la-Cabrerisse plague victims are the oldest samples from which Y. pestis F1 antigen has been, hitherto, identified. Few rural French cemetery containing plague victims have previously been identified and amongst them, only one dates to the 14th century. In the present report, we provide suggestive evidence of a second rural cemetery from southern France where victims of Y. pestis infection were buried. Our findings provide new information about the management of the plagued corpses during the “Black Death” in small rural communities.     

The use of an improved pRIA technique in the identification of protein residues

Blood and protein residue identification in archaeological research has been a controversial subject for the last 20 years. This paper reports on the use of an improved protein radioimmunoassay (pRIA) technique in identifying protein residues. Results from the blind testing of the original and improved pRIA techniques in identifying bloodstains on experimental lithic artifacts are described and compared. We argue that the improved pRIA technique is highly sensitive and accurate for identifying protein residues to genus, and thus has excellent applications for archaeological research.     

Lessons Learned from Seismic Analysis of a Seven-Story Concrete Test Building

A uniaxial shake table test of a full-scale slice of a seven-story reinforced concrete wall building was performed at the University of California, San Diego. A 2D analytical model that primarily employed fiber-based beam-column elements was used for a blind prediction of the global response of the building to the imposed input accelerations. An improved analytical model, which adequately simulates the building's dynamic response and comparison of measured and analytical results, is presented. The lessons learned from participation in the blind prediction with particular attention to the effects of issues commonly ignored in analytical modeling of concrete buildings are included.     

Mortality analysis of the Late Pleistocene bears from Grotta Lattaia,central Italy

Reported here are the results of a mortality analysis of an Ursus spelaeus death assemblage from Grotta Lattaia, southern Tuscany (central Italy), excavated in 1939. The Grotta Lattaia cave bears are among the latest representatives of the species. The large amount of cave bear remains indicates that the cavern was a lair for hibernating bears which repeatedly, but not necessarily yearly, occupied it. The mortality evidence indicates that deaths occurred primarily during hibernation from violent predation, and, therefore, that the bears had direct interaction with other carnivores. However, no sign of interrelation with humans could be found, even though Middle Paleolithic human remains and tools had been recovered associated with the bear material. Grotta Lattaia can be thus considered an example of cumulative, non-human-caused violent deaths in a hibernation context.     

Improved world-wide maps of monthly median foF2

New global maps of monthly median values of foF2 have been prepared using over 45,000 station months of foF2 observations, semi-empirical model values of foF2 in the mid-latitude ocean areas and empirical model values for the equatorial and high latitude regions. These observations have been carefully screened and mapped, using the Jones-Galley technique, to produce monthly median maps of foF2 for each hour, each month and for high and low levels of solar activity.     

Assessing the applicability of portable X-ray fluorescence spectrometry for obsidian provenance research in the Maya lowlands

Recent innovations in portable energy-dispersive X-ray fluorescence (PXRF) spectrometry have increased its utility for the geochemical characterization of obsidian artifacts for archaeological provenance research. However, concerns over the utility of PXRF instrumental analyses have been raised, focused on the validity and reliability of the geochemical data produced. Here we adopt the framework of Richard Hughes (On Reliability, Validity, and Scale in Obsidian Sourcing Research, 1998), whereby reliability addresses instrument stability and issues of measurement while validity pertains to an instrument’s ability to discern geochemical source provenance. This is done in order to test the utility of PXRF instruments for archaeological provenance research. k-Means cluster analysis was used to test the accuracy of PXRF through statistical comparison of data acquired via laboratory and portable energy-dispersive XRF instruments. Multivariate analysis was employed to demonstrate obsidian source representation at two Classic Maya archaeological sites in southern Belize – Uxbenká and Ek Xux – and to test the validity of data obtained from a PXRF instrument in answering archaeological research questions pertaining to regional interactions between lowland Maya polities. Results suggest that portable XRF instruments produce internally consistent results. However, data acquired from a PXRF instrument are not statistically equivalent to other XRF instruments. This is to say that while PXRF is not a reliable technique, it is valid for questions pertaining to geochemical source representation.     

Dysentery in the crusader kingdom of Jerusalem: an ELISA analysis of two medieval latrines in the City of Acre (Israel)

Dysentery was a significant cause of ill health during medieval times according to written sources of the period. However, it has been very difficult to detect the organisms that cause dysentery in archaeological samples from latrines and cesspools. This is because the cysts of the enteric parasites that cause dysentery are very small and usually fragment in the soil, in contrast to the robust ova of parasitic intestinal worms. This study uses a monoclonal enzyme-linked immunosorbent assay (ELISA) technique to identify the fragments of those enteric parasites that cause diarrhoea. Samples were taken from two excavated medieval latrines in the city of Acre. Coins and radiocarbon dating suggest that the latrines were in use during the thirteenth century CE. Positive results were noted for Entamoeba histolytica and Giardia duodenalis, while Cryptosporidium parvum was negative. This is the first time that either of these parasites have been identified in the Middle East using these methods.     

The volcanic eruption of Thera and its effect on the Mycenaean and Minoan civilizations

Since Professor Sp. Marinatos linked the eruption of Thera with the destruction of Cretan sites, difficulties have been met in reconciling the dates of the two incidents which, based on pottery, were c. 1520 BC and 1450 BC, respectively, giving a “time gap” of 70 years. None of the mechanisms proposed for the Cretan site destructions-tsunamis, ash fallout, earthquakes, civil disturbances or invasion can be reconciled with the magnitude of the simultaneous site destructions. Therefore, an alternative theory is proposed that the Cretan holocaust was caused by “nuées ardentes” emanating from Thera. It is postulated that these were released through a “split” in the cone wall, of limited area, generating a high velocity jet of tephra fluidized in a red hot gas stream. Such a jet is immensely destructive and lethal, causing death by pulmonary oedema. The shape (like a blowtorch) and course of the ash fallout, as measured by deep sea cores, shows that these nuées ardentes passed over the eastern part of Crete, causing severe destruction and depopulation. The geological record confirms that tephra deposits from such Peléan eruptions have travelled for 160km, or more, and that normally the main eruption is preceded by a preliminary one of lesser intensity, with a time gap ranging from 51 to 203 years. Settlements on or at the base of the volcano would have been abandoned at the time of the preliminary eruption/earthquakes (c. 1520 BC). A time gap of 70 years would be reasonable, fitting with the Cretan catastrophe around 1450 BC. In the meantime, reoccupation had commenced, but was terminated by the final eruption. Apparently, Knossos on the periphery of the blast was severely damaged by fire (possibly again in LM II) and rebuilt, being finally destroyed in late LM IIIB. During this time span some “blurring” of pottery dating may be attributed to recovery and use of pottery “heirlooms”. The nuée ardente theory explains the simultaneous destruction of sites by fire and blast, the Cretan depopulation, as well as the time gap. In general ¹⁴C results confirm the dates proposed. So far tephra deposits have not been identified on Crete itself, but grains of it have been found at Pyrgos. It is suggested that cores from lake bottoms should be examined for the area, and that Cretan soil samples should be checked for tephra particles by employing the flotation technique, used in mining, for separating them.     

Patterns of Interpersonal Violence at the Fisher Site

Abstract

Recent reanalysis of crania from the Late Prehistoric Fisher site in Will County, Illinois indicates relatively high levels of interpersonal violence. In the Big East and Big West mounds, cranial trauma was likely a result of repeated, low-level harassment of the villagers, resulting in the death of only a few people at a time. Numerous burials in the south-southwest mound, however, were interred in a large pit that reportedly contained at least 40 partially disarticulated individuals. Of those individuals from the mass burial pit, nearly all of the crania available for study showed evidence of perimortem trauma. These victims were likely the result of a large-scale attack that resulted in numerous deaths and subsequent abandonment of the site. Accelerator mass spectrometry (AMS) of radiocarbon dates indicate that this violence was occurring between about A.D. 1225 and 1300, a period that seems to have been a particularly volatile one in Late Prehistoric Illinois.     

Radiocarbon age determinations of fossil Margaritifera auricularia (Spengler) from the River Thames in West London

In the early 1900s shells of a large freshwater mussel, Margaritifera auricularia (Spengler), were discovered in calcreted gravel dredged from the channel of the Thames at several sites between Mortlake and Battersea in west London. These specimens were said to have been associated with Neolithic polished stone axes, supposedly as food remains. M. auricularia is now extinct in Britain, but it has been reported living in several large rivers in southern Europe although apparently not in recent years. Three radiocarbon dates of 4140±50, 4340±45 and 4860±40 bp have been obtained from Thames specimens, supporting a Neolithic age for these shells. The theory that the shells represent debris from imported human food is discounted and it is considered more likely that M. auricularia was actually living in the Thames in Neolithic times. Its extinction in Britain should be seen as part of a general recession during the Post-glacial, as revealed by fossil occurrences to the north and east of its present-day range.     

Adaptive separation of regular and irregular magnetic activity for K indices

A numerical data adaptive separation method is developed for the discrimination of quasi-regular magnetic variations from the irregular variations for the determination of the K indices. The method is based on a pattern comparison and discrimination technique using harmonic analyses and is more objective than the hand-scaling method. The wave characteristics of a quiet regular or reference day are compared with those of the disturbed day being examined. The harmonic components that are consistent with those of the reference day are determined by a cosine weighting function. The Fourier coefficients are calculated from these modified harmonics and are then transformed back to the time domain. This ‘regular variation’ is subtracted from the data before the ranges are determined for the semi-logarithmic K scale. The method is tested on digital data from the Canadian magnetic observatories Victoria, Meanook and Ottawa over a 4 month period. The data are at a 10 s sampling interval and encompass the full range of K values (0–9). These K values are compared and checked with hand-scaled values, which were carefully and independently determined from reconstructed magnetograms from the same data. The two methods were found to agree ∼ 97% of the time, with most errors occurring during very irregular periods. This is comparable with values carefully determined by highly skilled observers. It is proposed that the method is suitable for use on a regular basis.     

Diurnal and seasonal variability of the southern-hemisphere main ionospheric trough from differential-phase measurements

A differential-phase technique utilizing the radio transmissions of NNSS satellites was used to make measurements of the latitudinal variations of ionospheric vertical total electron content (TEC) in the southern mid-latitude trough region from the location of Macquarie Island (a cis-auroral site; geographic coordinates 54.5°S, 154.95°E, geomagnetic coordinates 64.5 S, 177.67 E, L = 5.38) for a period of 14 months during 1987–1989. The differential-phase method provided a means of observing a relatively large expanse of ionosphere whilst centered on the cis-auroral region which was well suited for trough studies. By monitoring the two transmitted radio signals at 150 and 400 MHz from the Navy Navigation Satellite System (NNSS) polar orbiting satellites it was possible to deduce the latitudinal variation of ionospheric vertical TEC for the duration of the satellite pass. The absolute TEC was derived from Faraday-rotation and ionosonde data obtained during the same period.The main findings of this work have been the high incidence of daytime troughs for all seasons and the relative low incidence of night-time troughs. Both summer and vernal equinox seasons display a greater occurrence frequency of daytime troughs than the winter and autumnal equinox seasons. Winter-time troughs at any time are less frequent than for any other season. Comparisons with the northern-hemisphere trough display a marked difference in occurrence frequency and distribution of troughs. An attempt to explain some of these features in the light of the high-latitude convection theory is offered. Case studies are given for all seasons to highlight these findings.     

An evaluation of Keeley's microwear approach

Lawrence Keeley has developed a microwear approach to lithic use-wear analysis which he claims will enable an investigator to reconstruct aspects of implement function. A notable feature of his approach is the assertion that distinctive wear-polishes form as a result of contact with specific worked materials, making the identification of worked materials possible. To verify the power of this approach, an independent “blind test” was conducted in which Keeley attempted to identify the uses of a set of experimental implements. While the test results support the utility of Keeley's approach in identifying worn areas on an implement and kinematics of use, we suggest the results do not demonstrate the existence of characteristic wear-polishes and thus question the efficacy of this technique in identifying worked materials.A reply by Keeley to this evaluation follows this paper.     

Histological identification of bone fragments in archaeology: telling humans apart from horses and cattle

In archaeology, it is not always possible to identify bone fragments. A novel approach was chosen to assess the potential of histology as an identification tool in those instances in which macroscopical study (e.g. by means of bone surface texture) has failed. This study concentrated on the diaphyses of long bones in three species of comparable size which are relevant to archaeology. Late juvenile and adult human diaphyseal bone structure was compared with the bone structure of horses and cattle. Since bone structure can differ even within a single bone, the restrictions in terms of bone category, bone part and species were deemed necessary for the development of a useful identification method for archaeological bone. The reference series comprised long bones from several individuals to broaden the insight into variations in diaphyseal bone structure within a single species. A general difference in the primary bone types was found between humans and the two large mammals. Human bone displayed lamellar bone types, whereas horses and cattle showed fibrous bone types. The only exceptions were separated growth layers. A difference in the secondary bone structure was also observed. A large number of connecting, primary (Volkmann's) canals, giving the secondary bone a reticular aspect, were common in horses and cattle. They were not, however, present in the human bones studied. To confirm the validity and applicability of these differences, a blind test was conducted on 15 diaphyseal fragments of identified long bones from archaeological sites. The results were very promising. Although four fragments could not be identified due to severe degradation, all the others were correctly attributed. Copyright © 2006 John Wiley & Sons, Ltd.     

A Roman cat skeleton from Quseir on the Red Sea coast

During excavations at Quseir el-Qadim on the Red Sea coast, the body of a Roman cat was recovered. The skeleton is nearly complete and remains of the fur, stomach, and lower intestinal tract are also preserved. This animal was a very large and heavily built male domestic cat. Shortly before his death, the cat had eaten at least six rats (Rattus rattus), remains of which were found in the stomach and in the dung balls.
