Palaeobiology of the Medieval Population of Albano (Rome,Italy): A Combined Morphological and Biomolecular Approach

Recent years have seen increased interest in skeletal populations from the Imperial Roman Age in Italy, but much less is known about diet and standards of living in the subsequent medieval period. To fill this gap, we conducted a morphological analysis of human remains from Albano, an Italian town near Rome, as well as a stable isotope analysis of bone collagen to reconstruct diet. The sample was recovered from a Medieval cemetery (1040–1220 cal. yr. BP) located in the gardens of the historical Palazzo Doria Pamphili in Albano. A minimum number of 40 individuals (31 adults and 9 sub‐adults) were examined using standard methods. Though the general health status of the population was good, signs of cribra orbitalia and diffuse enthesopathies were noted during the morphological examination. Stable carbon and nitrogen isotope analyses of the bone collagen from 24 adult humans and three faunal bones indicate that the diet of the population may be described as predominantly terrestrial and C₃‐plant based although the data for some of the individuals suggest a modest consumption of C₄‐(millet) based or aquatic proteins. No evidence of significant dietary differences between the sexes was found. The comparison of the isotope data from Albano with those from populations recovered in the same region is consistent with a shift from a terrestrial, possibly plant foods‐dominated subsistence in the Early Middle Ages to a diet with a higher contribution from animal proteins, both terrestrial and aquatic, in the Later Middle Ages.

A new petauroid possum (Marsupialia,Pseudocheiridae) from the Pliocene Bluff Downs Local Fauna,northern Queensland

Pseudochirops winteri n. sp. is described from the Pliocene Bluff Downs Local Fauna on the basis of a left dentary fragment with M₂. It is considered to be most similar to P. archeri although its phylogenetic position must remain tentative until further material is found. The presence of this presumably rainforest-dwelling possum, the first from this fauna, may indicate a limited closed forest component. Given the paucity of additional rainforest taxa recovered from this site despite extensive screen washing, however, such a component must have been restricted to gullies or riparian fringes.     

Bat cave and Hobbit hole,microbats of Liang Bua (Flores,Indonesia)

Liang Bua is a limestone cave on the island of Flores, Indonesia. Palaeontological and archaeological excavations at this site have unearthed one of the best insular records of fossil bats to date. The assemblage is numerically dominated by the horseshoe bat species Rhinolophus euryotis, followed by the leafnosed bat Hipposideros diadema. In addition to these species, remains of Rhinolophus simplex, Hipposideros sp. cf. H. sumbae, Murina sp. aff. M. florium, Taphozous sp., Kerivoula sp. and Miniopterus sp. have also been recovered. Two taxa found in Liang Bua, Rhinolophus euryotis and Miniopterus sp., are not apparent in the modern bat fauna of Flores. Some specimens, found during the more recent excavations, are known from specific depths. Two age-groups are represented. The stratigraphically oldest is 74–61 ka and includes Murina sp. aff. M. florium and Rhinolophus euryotis. Conversely, the younger, Holocene, assemblage is much more diverse. Despite the relatively small amount of microbat material collected thus far, it displays a higher diversity than the rodents from the site. This is presumably related to the better dispersal ability of bats relative to other, non-volant mammals.     

Late Stone Age subsistence in the Tilemsi Valley, Mali: Stable isotope analysis of human and animal remains from the site of Karkarichinkat Nord (KN05) and Karkarichinkat Sud (KS05)

The pathways leading to the adoption of cereal cultivation and pastoralism in West Africa are poorly understood. In order to elucidate the transition to food production during the Late Stone Age in Mali’s Tilemsi Valley samples of ancient and modern human and animal remains were selected for carbon and oxygen isotope analysis. Our results indicate the inhabitants of Karkarichinkat Nord (KN05) consumed considerable quantities (85%) of carbon derived from C₄ plants, either directly in the form of C₄ grasses such as wild Panicum sp. and possibly domestic Pennisetum sp. or indirectly through the consumption of C₄ grazers such as Bos sp. and Ovis sp.     

Incisor microwear textures of five bioarcheological groups

Dental microwear texture analysis has proven to be a valuable tool for inferring aspects of subsistence behaviour in human groups and diet in other mammals. Studies have to date been limited to molar teeth. Here we report on the first microwear texture analysis of incisors. Five bioarcheological groups were included in this analysis: Aleuts from various islands in the Bering Sea (n = 24), Arikara from the Mobridge site in South Dakota (n = 18), ethnic Chinese cannery workers from Kodiak Island (n = 16), a Late Woodland Bluff sample from Jersey County, Illinois (n = 18) and Puye Pueblo from Pajarito Plateau in New Mexico (n = 18). First, point clouds with 0.18 µm lateral spacing and 0.005 µm vertical resolution were obtained from maxillary central incisor labial surfaces using a white‐light confocal profiler. Four adjoining fields were sampled for a total area of 276 µm × 204 µm for each specimen. Surface data were then imported into scale‐sensitive fractal analysis software for texture characterisation. Results indicate significant variation among groups in anisotropy, fill volume and heterogeneity. These differences are likely related to differences in diet, degrees and types of non‐dietary incisor use, as well as exposure to abrasives. This study also suggests that texture variables most useful for characterising and comparing incisor microwear may differ from those most useful for distinguishing molar microwear patterns.

Permian brachiopods from the Tupe Formation,San Juan Province,Precordillera, Argentina

The brachiopod fauna from the Tupe Formation at La Herradura Creek, located on the west flank of Perico Hill, San Juan Province, Argentina, palaeogeographically belongs to the western sector of the Paganzo basin (‘Guandacol embayment’). The stratigraphical section of the Tupe Formation at La Herradura Creek is the stratotype of the Tivertonia jachalensis-Streptorhynchus inaequiornatus biozone, was previously regarded as being of Late Carboniferous age but here is assigned to the earliest Permian (Asselian). We describe and review the biozone assemblage, which consists of Streptorhynchus inaequiornatus, Tivertonia jachalensis, Kochiproductus sp., Costatumulus sp., Coronalosia argentinensis, Tupelosia paganzoensis, Trigonotreta pericoensis, Septosyringothyris sp. aff. Septosyringothyris jaguelensis and Crurithyris? sp. This brachiopod assemblage is related to Indian and Australian Early Permian faunas and its presence in the La Herradura Creek section provides new evidence in support of an Asselian (Early Permian) age for the Tivertonia jachalensis-Streptorhynchus inaequiornatus biozone. This assemblage is also important for intra- and inter-basinal correlation because several of its characteristic species have been identified from other sections of the Paganzo basin and the Río Blanco basin. The proposed age for this biozone is consistent with the age of palynological data from slightly above the marine faunas from the stratotype locality.     

Mortality curves for horses from the Middle Palaeolithic site of Bau de l'Aubesier (Vaucluse, France): methodological, palaeo-ethnological, and palaeo-ecological approaches

A new methodology for estimating the age of death of horse, based on the degree of hypsondonty, has been established using the dental material of Equus mosbachensis, Equus cf. taubachensis, and Equus sp., which were hunted from the Mousterian levels of the Bau de l'Aubesier at Monieux (Vaucluse, France). Our model is based on a regression analysis of curvilinear type, and allows the precise determination of age classes intervals and the distribution of estimated ages, by systematically taking into account the standard deviation. These estimates were tested from all the paired teeth of horses belonging to the same individuals, from the sites of Bau de l'Aubesier and of Jaurens at Nespouls (Corrèze, France).The age structures of the horses of Bau de l'Aubesier were compared in the different levels of the sequence with their frequencies, survival rates, and mortality rates corresponding to as many curves as often used in population ecology and demographics. The different age classes of a present-day natural African population (Equus burchelli boehmi), the individuals having died accidentally in the National Park of Akagera (Rwanda) following a bush fire, provide an interesting comparative catastrophic model with regard to the population dynamics, and permit us to evaluate the impact of Neandertals on the Equidae fossils of Bau de l'Aubesier. Our assemblage clearly indicates in the lower layers, a systematic selection of adult horses, as opposed to the upper sequence where juveniles and adults dominate. Ecological factors, such as seasonal migratory phenomena and herd gathering, which characterise many large size species are also tackled and could explain the high proportion of adults in French Middle Palaeolithic sites where horses were preferentially hunted.     

Ordovician stromatoporoids from Tasmania

The Hunter Siltstone near Grenfell, New South Wales, contains a rich Upper Devonian fish fauna including the sinolepid Grenfellaspis and the new antiarchs Bothriolepis grenfellensis sp. nov. and Remigolepis redcliffensis sp. nov. Bothriolepis grenfellensis sp. nov. is the first bothriolepid species described from N.S.W., and R. redcliffensis sp. nov. is the first species of Remigolepis described from Australia. Traditionally, the Hunter Siltstone was considered to be uppermost Famennian or earliest Carboniferous in age based on the presence of Grenfellaspis, and the related taxon Sinolepis, which is known from the Wutung and Sanmentan formations of southeastern China. However, available data indicates the Hunter Siltstone may be early Famennian in age. Ongoing work suggests that all Famennian Bothriolepis from N.S.W., including B. grenfellensis, possess a trifid preorbital recess, but differ in other aspects of headshield morphology. In North China, the Famennian Zhongning Formation contains six species of Remigolepis and a species of Sinolepis. However, R. redcliffensis does not show any similarity to these species beyond those of Remigolepis as a whole.     

VIVARIA IN DOLIIS. CERAMIC JARS FOR DORMOUSE FATTENING FOUND IN ARUCCI

The excavation of the north house at the archaeological site of Arucci (Aroche, Huelva) has provided interesting data for understanding city planning in general, and domestic architecture in particular. Investigation of their environments has allowed the identification of the distinct functions for which they were intended, including two significant tabernae that were connected to one of the main thoroughfares of the city. In one of them, an interesting set of ceramic fragments has been recovered, whose features allow us to recognize them as ceramic containers for fattening the much-appreciated dormouse. This find signifies an interesting novelty in the archaeological record of the city from which various aspects of the diet of its inhabitants can be inferred, as well as the breeding and production of the rodents.     

Early Miocene bivalves from the Cape Melville Formation,King George Island,West Antarctica

Seven species of marine bivalves, including six new taxa, are described from the Cape early Miocene Melville Formation which crops out on the Melville Peninsula, King George Island, West Antarctica. The bivalve assemblage includes representatives of the families Nuculidae, Ennucula frigida sp. nov., E. musculosa sp. nov.; Malletidae, Neilo (Neilo) rongelii sp. nov.; Sareptidae, Yoldia peninsularis sp. nov.; Limopsidae, Limopsis psimolis sp. nov.; Hiatellidae, Panopea (Panopea) sp. cf. P. regularis; and Pholadomyoida (Periploma acuta sp. nov.). Species studied come from four sedimentary sections measured in the upper part of the unit. Detailed morphologic features of nucloid and arcoid species are exceptionally well preserved and allow for the first time reconstruction of muscle insertions as well as dentition patterns of Cenozoic taxa. Known geological distribution of the species is in agreement with the early Miocene age assigned to the Cape Melville Formation. The bivalve fauna from Cape Melville Formation is the best known from Antarctic Miocene rocks, a time of complex geologic, paleogeographic and paleoclimatic changes in the continent. The new fauna introduces new taxonomic and palaeogeographic data that bear on the question of opening of sea gateways and distribution of Cenozoic biota around Antarctica.     

Isotopic Evidence for Marine Consumption and Mobility in the Atacama Desert (Quillagua,Northern Chile)

Archaeological research in the Atacama Desert has recovered evidence of considerable cultural variability. This variability seems to have increased during the Late Intermediate Period (AD 950–1400). The oasis of Quillagua, located at the margins of the Loa River in northern Chile, between the Andes and the coast (70 km from the Pacific Ocean), has shown important evidence regarding this cultural diversity. The variety in the archaeological evidence found at Quillagua has been interpreted as the result of two different cultural influences at the oasis: the Pica‐Tarapacá who occupied the coastal and inland regions to the north of Quillagua and the Atacama who occupied the oasis and fertile areas southeast of Quillagua. Here, we present the results of stable carbon, nitrogen and oxygen isotope analyses of 23 individuals recovered from the Cementerio Oriente in Quillagua, in order to test whether the observed cultural variability is also reflected in diet and mobility patterns. Results from carbon and nitrogen isotope measurements indicate the importance of marine protein, as well as a contribution of maize in the diet of some individuals. Four individuals show low δ¹⁸O values, suggesting a possible highland or non‐local origin, whereas values for the remaining individuals are consistent with lowland populations. Together, the results support the idea that the Quillagua oasis represented an important site of interaction between the Tarapacá and Atacama cultures, with close contacts with the coast but also with the presence of individuals from the highlands.

MEAN SHIFT: A NON‐PARAMETRIC ALGORITHM FOR THE SEGMENTATION OF ANOMALIES IN GEOPHYSICAL IMAGES OBTAINED FROM MAGNETIC PROSPECTION DATA

This paper studies the applicability of the Mean Shift algorithm as support in interpreting geophysical images produced, on this occasion, from magnetic prospection data. The data obtained from a magnetic survey carried out in Gilena (Seville province, Spain) by the La Rábida Archaeophysics Group will be used for the research. Its applicability is illustrated by comparing, on the one hand, some reduction‐to‐pole algorithms and on the other, the (well‐known) k‐means algorithm. Finally, the paper shows the results obtained by applying the Mean Shift algorithm as an alternative method to ‘unsupervised clustering’ of anomalies that appear in images obtained from geophysical data, in which the a priori knowledge of the number of classes is difficult or impossible.     

Starchy shells: Residue analysis of precolonial northern Caribbean culinary practices

Determining culinary practices is critical for understanding phytocultural complexes, transported landscapes and human niche constructions. Starch analysis is an exemplary method for reconstructing human–plant dependencies. However, certain types of artefacts from the Greater Caribbean region, such as flaked lithics, lithic griddles, coral artefacts and shells, have not been extensively analysed for starch remains. Moreover, there has been no comparison of culinary practices between The Bahama archipelago and the Greater Antilles (the presumed origin of foodways transported to The Bahama archipelago). The paper investigates 60 bivalve shell artefacts for starch remains, which were recovered from three archaeological sites: El Flaco and La Luperona (Dominican Republic), and Palmetto Junction (Turks & Caicos Islands). In contrast to ethnohistorical narratives that characterize shell tools exclusively as manioc peelers, the starch remains recovered in this study suggest a broader suite of plants and functions. The results provide evidence that a diversity of plants (Dioscorea spp., Dioscorea trifida L., Fabaceae, Ipomoea batatas L., Manihot esculenta Crantz, cf. Zea mays L., cf. Acrocomia media O. F. Cook, and Zingiberales) were prepared with these shells. This new evidence contributes to ongoing discussions about culinary practices in the Caribbean and other related late precolonial (c.800–1500 ce ) foodways.     

Gated communities as spatial manifestations of moral differentiation and competition: an example from Istanbul,Turkey

Gated communities have received significant attention in academic debates. Despite this, there is a lack of studies on differentiation and tensions between them. This paper analyses differentiation between gated communities by adopting the theory of “symbolic boundaries” [Lamont, M., 1992. Money, morals, and manners: the culture of the French and American upper-middle class. Chicago, IL: University of Chicago Press]. It uses the data collected from fieldwork in two gated communities in Istanbul, Turkey, comprising semi-structured in-depth interviews with residents. First, the paper contributes to Lamont's “symbolic boundaries” [Lamont, M., 1992. Money, morals, and manners: the culture of the French and American upper-middle class. Chicago, IL: University of Chicago Press] by showing that morality is not independent from socio-economic context, but indicates the legitimate values of a given social context. This is shown in residents’ use of moral boundaries such as a law-abiding lifestyle, legitimate sources of capital accumulation and the existence of warmer relations with each other. Second, the paper contributes to the study of gated communities by demonstrating that they can be regarded as spatial manifestations of the division within the upper classes which results from competition for deserved status.     

Phylogenetic implications of macropodid (Marsupialia: Macropodoidea) posteranial remains from Miocene deposits of Riversleigh,northwestern Queensland

A new sthenurine taxon, Rhizosthenurus flanneryi gen. et sp. nov. from middle late Miocene deposits of Riversleigh, northwestern Queensland, is established on the basis of material previously assigned to Bulungamayinae. Postcranial remains belonging to an indeterminate basal macropodid are described. Cladistic analysis of 50 discrete postcranial characters coded for 16 ingroup and two outgroup taxa suggests that R. flanneryi is the most plesiomorphic member of a clade containing the late Miocene macropodid Hadronomas puckridgi and crown-group sthenurines. The indeterminate basal macropodid is placed as the immediate sister taxon to the bulungamayine Ganguroo bilamina and a monophyletic clade containing macropodines and sthenurines. This arrangement supports consideration of bulungamayines as ancestral to other macropodids and suggests that macropodines and sthenurines are monophyletic. However, the possibility of a diphyletic origin for Macropodinae and Sthenurinae from within Bulungamayinae cannot be dismissed.     

Umkomasia (megasporophyll): part 1 of a reassessment of Gondwana Triassic plant genera and a reclassification of some previously attributed

The genus Umkomasia, a megasporophyll, belonging to the pteridosperms (seed ferns) in the family Umkomasiaceae (Corystospermaceae), is reassessed comprehensively worldwide. All previous records are analysed. Certain fertile structures previously attributed are reclassified. Umkomasia is shown to be restricted to the Triassic of Gondwana where it is associated with the genus Pteruchus, a microsporophyll, and the genus Dicroidium, a vegetative leaf. It is well represented from Argentina, Australia and southern Africa where the Molteno Formation is by far the most comprehensively sampled with eight species described. Two specimens from the upper Permian of India attributed to Umkomasia are reclassified as cf. Arberiopsis sp. A whorled fertile structure from Antarctica, previously assigned to Umkomasia, is reclassified in a new genus as Axsmithia uniramia. Another compression fossil and the permineralized Umkomasia resinosa remain as valid records from Antarctica. The material described as Umkomasia from the Triassic of China is reclassified as Stenorachis asiatica. The Lower Jurassic record from Germany is placed in a new genus as Kirchmuellia franconica. The records of Umkomasia sp. from the Rhaetic of Germany are reclassified as cf. Kirchmuellia sp. and the single specimen from the Jurassic of Libya as genus et sp. indet. The Lower Cretaceous record from Mongolia has been reclassified by other researchers as Doylea mongolica. A pictorial key to Umkomasia species is provided, geographic and stratigraphic distributions are tabulated.     

Biostratigraphic potential of Middle Cambrian hyoliths from the eastern Georgina Basin

Fourteen hyolith taxa are documented from the Middle Cambrian (Templetonian to Floran) of the eastern (Queensland) portion of the Georgina Basin, Australia, as a contribution toward a prospective Australian Cambrian hyolith biozonation. The described fauna is from the Beetle Creek Formation (including Monastery Creek Phosphorite Member) and Gowers Formation. Additionally, the enigmatic Cupittheca and some indeterminate hyoliths are figured to illustrate aspects of hyolith morphology. Guduguwan hardmani, widespread in Ordian-early Templetonian strata of northern Australia, is here recorded from the early Templetonian of the eastern Georgina Basin. A new family Gakidae is established for sulcavitide hyolithomorphs with a conch of pentagonally tabernacular transverse section, to include Gaka, Kalkatungu gen. nov. and possibly Dorsolinevitus. New genera are the hyolithid Yalarrnga mara gen. et sp. nov., sulcavitid Kulangarra kutjurru gen. et sp. nov., gakid Kalkatungu murlu gen. et sp. nov. and angusticornid Yuku tjurtu gen. et sp. nov.; new species are Loculitheca kunka sp. nov., Carinolithes tjikilirri sp. nov., ?Sololites kankari sp. nov., ?Shandongolithes thakal sp. nov., ?Gerkella thuka sp. nov. and ?Yacutolituus rakatju sp. nov. Taxa in open nomenclature are Foersteotheca cf. dubecensis, ?Holmitheca sp. and ?Dorsojugatus sp. On present knowledge, the potential for an Australian Cambrian hyolith biozonation is limited in the Early Cambrian, but for the Middle Cambrian, G. hardmani is a widespread Ordian-early Templetonian indicator, while hyolith distribution in the Monastery Creek Phosphorite Member suggests a faunal turnover at or about the incoming of Acidusus atavus which may provide a basis for biozonation in the Floran stage.     

Stable isotope investigations of charred barley (Hordeum vulgare) and wheat (Triticum spelta) grains from Danebury Hillfort: implications for palaeodietary reconstructions

Palaeodietary studies typically focus on the analysis of bone collagen due to the limited availability of plant remains. Isotopic analysis of plant remains, however, allow for a more extensive consideration of the contribution of plants to the human diet and can potentially provide information about the environment in which the crops were grown. This paper reports the results of carbon and nitrogen isotope analyses performed on charred barley and wheat grains recovered from pits within Danebury Iron Age hillfort. To the best of our knowledge, this is the first Iron Age site in Britain from which charred grains have been isotopically analysed. Our results suggest that cereals found at the hillfort were grown in several different environmental contexts. The isotope data demonstrate that the herbivores were not consuming a diet primarily based on grains as the δ¹⁵N values of the grains are very similar to those of the herbivores. Palaeodietary investigations typically assume that humans eating plant protein only would have the same δ¹⁵N value as the local herbivores. This assumption is clearly invalid at Danebury, where the humans and animals appear to have consumed either different parts of the same plants or different plants. Researchers typically interpret high differences between human and animal δ¹⁵N values as indicative of diets high in animal protein, however where major plant resources have δ¹⁵N values similar to those of the herbivores our ability to distinguish between plant and animal sources of protein in the diet is limited. Our research has demonstrated that whenever possible it is desirable to measure the isotopic signatures of potential major plant resources in order to understand past subsistence strategies.
