The Role of Ancient Fishing on the Desert Coast of Patagonia,Argentina

ABSTRACT

This article explores latitudinal and chronological variations in the exploitation of marine fish by the hunter-gatherers who occupied the Atlantic coast of continental Patagonia, Argentina, since the mid-Holocene. Results indicate a spatial gradient in the importance of fish. A significant reduction in the frequency of fish remains in the archaeological sites occurs at higher latitudes. The chronological trends identified also suggest differences between the assemblages of the northern and southern coasts of this long littoral area. The results obtained are further discussed in relation to identified environmental and cultural variation.     

Beavers (Castor fiber) in the Past: Holocene Archaeological Evidence for Beavers in Romania

Archaeological beaver (Castor fiber) remains from Romanian sites dating from the Mesolithic to the Middle Ages are described in terms of their frequencies (based on the number of identified specimens), morphology and size. A summary of previous archaeozoological studies in the geographical and historical regionalization of the Romanian territory (i.e. Banat, Dobrudja, Moldavia, Muntenia, Oltenia and Transylvania) shows that temporal and regional variation characterizes the assemblages. The data also reveal that beaver hunting contributed little to local economies, although some spatial and temporal variations are apparent and are here compared with the evidence from the historical record. In addition, univariate, bivariate and geometric morphometric analyses are employed to examine different anatomical elements. Studies of the lower third molar (M₃) reveal that there is a statistically significant intraspecific variability between the Neolithic and Iron Age populations, situated also in different regions, Muntenia and Moldavia, respectively.

Osteometric Analysis of South American Sea Lions (Otaria flavescens) Pups From Patagonia. An Assessment of Their Use as Indicators for Seasonality in Archaeological Sites

Zooarchaeological analyses of pinniped remains have been scarce in South America because of lack of specific studies of species determination and estimation of age and sex. Nonetheless, the presence of small and unfused bones (assigned as pup remains) of Otaria flavescens (O. flavescens) in the Patagonian archaeological record has been frequently used as an indicator of summer occupation accomplished by ecological analogues. For this reason, we carried out a postcranial skeletons osteometric study of modern pups of South American sea lions (O. flavescens) with known sex and aged 0–12 months, allowing a more precise age estimation of archaeological samples. Then, we revisited the evidence for seasonality in the Cabo Virgenes 6 site at Cabo Virgenes locality, one of the archaeological localities in Patagonia where the seasonality has been determined only on the basis of the presence of unfused pup bones. Our metric data study on a modern sample shows that the regression analyses generated a complementary and dependable age estimation model for unfused appendicular bones of O. flavescens between 0 and 12 months old that can be applied to samples recovered from archaeological sites. These osteometric studies of postcranial elements allow us to adjust the age estimation of the animal's death and re‐examine seasonality of the Cabo Virgenes 6 site (Santa Cruz, Argentina).

Bioarchaeological Patterns of Violence in North Patagonia (Argentina) during the late Holocene. Implications for the Study of Population Dynamics

This work presents bioarchaeological patterns of interpersonal violence inferred for Northeastern Patagonia (Argentina) during the late Holocene. The main goal is to evaluate if there is a significant increase in the frequency of indicators of violence during the final late Holocene, prior to colonial times, in possible concordance with the Medieval Climatic Anomaly (ca. 1150–600 years BP). A sample of skulls (n = 797) was studied through a series of methodological steps that included the evaluation of their state of preservation and the study of potential injuries, taking into account the degree of ambiguity of the diagnosis. The sample was divided into three chronological groups: early (ca. 3500–2500 years BP), middle (ca. 2500–1500 years BP) and late (ca. 1500–400 years BP). The individuals were also separated according to sex, age category and geographical distribution. Although a temporal trend toward increased violence was detected, it was not statistically significant. There was also a higher percentage of positive cases in Northern individuals compared to the Southern ones, and between males compared to females, but neither case had statistically significant differences. Alternative mechanisms, such as population dispersals, exchange and use of buffer areas, that may have functioned to dispel social tensions, are proposed.

An experimental approach to the study of interpersonal violence in Northeastern Patagonia (Argentina), during the late Holocene

This paper incorporates an experimental approach to the study of violence patterns in Northeastern Patagonia (Argentina) during the late Holocene. The underlying hypothesis considers a close association between socio-ecologic alterations during the Medieval Climatic Anomaly (MCA) (ca. 1150-600 years BP; Stine, 1994, 2000) and a probable increase in conflict levels. In order to test this hypothesis, human skulls (n = 986) were analyzed for bone lesions, discriminating late bone lesions, such as those produced by metal tools. The experimental approach used swine (Sus scrofa domestica) skulls, as proxies for human skulls, and incorporated original sabers. From this discriminating analysis, it can be inferred that no significant increase in violence signs were recorded until the first stages of Hispanic-indigenous contact (first half of 17th century). These findings emphasize the need for a revision of the implications of the dynamics of human populations in Northeastern Patagonia during the late Holocene.     

Archaeological data on the exploitation of the goose barnacle Pollicipes pollicipes (Gmelin, 1790) in Europe

Barnacles of the species Pollicipes pollicipes are crustaceans that nowadays live on wave-beaten rocky substrates in the intertidal and low-shore zones on the coasts of Atlantic Europe and North Africa. At the present time, the exploitation of this species is profitable, especially in northern Spain where this sea-food is highly valued, as well as expensive. However, the gathering of this resource, which is carried out manually by the percebeiros or “goose barnacle fishers” entails great risks.     

Patterning and Its Causation in the Pre-Neolithic Colonization of the Mediterranean Islands (Late Pleistocene to Early Holocene)

In 1981 one of us (Cherry) first attempted to identify spatial and temporal patterning in the human colonization of the Mediterranean islands. Since the 1980s, slowly accumulating evidence has suggested that the Mediterranean islands were sporadically inhabited by hunter-gatherers during the Late Pleistocene and Early Holocene. Here we seek to establish whether or not these data exhibit regularity. We suggest that evidence for Upper Palaeolithic to Mesolithic activity, tending to cluster on larger or less remote islands, indicates that while humans were clearly capable of reaching the Mediterranean islands prior to the Neolithic, their general reluctance to do so can be explained in terms of the variable environmental attractiveness of the insular Mediterranean. Tending to be relatively small, dry, and biologically depauperate, the Mediterranean islands were largely inhospitable to mobile groups preferring extensive territories with diverse and robust biotas. Sedentism only became a widely viable strategy in the insular Mediterranean with the development in the Neolithic of what we might regard as “terraforming”—that is, the introduction of cereals, pulses, and ovicaprids, all tolerant of xeric environments.     

Great white shark teeth used as pendants and possible tools by early‐middle Holocene terrestrial mammal hunter‐gatherers in the Eastern Pampas (Southern South America)

Two great white shark (Carcharodon carcharias) teeth recovered in a terrestrial mammal hunter‐gatherers context in the Pampas are described. Associated lithic (mainly quarzite) tools, and the predominant exploitation of the Lama guanicoe relate the ancient inhabitants of the site with those of the early‐middle Holocene sites of the Area Interserrana of the Provincia de Buenos Aires. According to the stratigraphic context and the terrestrial fauna, the age of the deposit seems to be constrained to the early‐middle Holocene. The root tips of the shark teeth are marked by an artificial transvers groove fitted to tie a thread. Tooth edge serrations are strongly eroded, suggesting they were used as tools. We favour the hypotheses that the fish could have stranded on the beach or a small estuary in the neighbourhood, or that the teeth were obtained from the body of a pinniped attacked by a shark and sobsequenty found by humans.

Saharan prehistoric basketry. Archaeological and archaeobotanical analysis of the early-middle Holocene assemblage from Takarkori (Acacus Mts., SW Libya)

The paper presents the large set of basketry and other worked fibre artefacts constituting the perishable artefacts assemblage from the Takarkori rock shelter. This site is located in southwestern Libya, central Sahara. Its well-preserved Holocene stratigraphy testifies to human occupations by foraging groups (Late Acacus culture; ca. 9000–7400 uncal years bp; ca. 8300–6100 BCE) and herders (Pastoral cultures; ca. 7400–4500 uncal years bp; ca. 6400–3000 BCE).     

Chemical and Petrographic Analysis of Pre‐Hispanic Pottery from the Southern Abaucán Valley,Catamarca, Argentina

Neutron activation (NAA) and petrographic analyses were carried out on Late and Inca Period pottery from 15 archaeological sites and several clay samples in the southern Abaucán Valley, Catamarca, Argentina. The results from the NAA and petrographic analyses provide new data concerning local versus non‐local pottery production and vessel exchange for these two pre‐Hispanic cultural periods. The chemical data demonstrate the use of different clay sources over time until the Inca appearance in the region, when a more structured and controlled production is observed. Petrographic analyses show a similar change in the ceramic paste recipes used by ancient potters.     

The Holocene Archaeological Sequence of Shum Laka Rock Shelter (Grassfields, Western Cameroon)

Until recently the Grassfields (western Cameroon), cradle of the Bantu languages, were an unknown zone from the archaeological point of view. The excavations of Shum Laka rock shelter by de Maret and his team brought the most complete sequence in West Africa, spanning the Late Pleistocene and the Holocene. After 20 millennia of microlithic tradition (Late Stone Age), a new culture, with macrolithic tools, polishing and pottery (Stone to Metal Age), slowly developed ca. 7000 B.P. onwards. From this early period on, forest hunting was associated with the exploitation of Canarium schweinfurthii. Around 4000 B.P., an industry with waisted axes, blades, and pottery had emerged. With a striking technological continuity, this culture survived throughout the Iron Age. Increasing importance and diversity of trees exploited through the Stone to Metal Age and the Iron Age suggests arboriculture. Regional comparisons show that, between 5000 and 2500 B.P., an original culture developed in the Grassfields and the Cross River basin.Jusqu'à récemment, les Grassfields (Cameroun occidental), berceau des langues bantoues, étaient inconnus d'un point de vue archéologique. Les fouilles de l'abri de Shum Laka par de Maret et son équipe permirent d'établir la plus complète séquence d'Afrique occidentale, embrassant la fin du Pléistocène et l'Holocène. Après 20,000 millénaires de traditions microlithiques (Age de la Pierre Récent), une nouvelle culture, caractérisée par l'apparition d'outils macrolithiques, de polissage et de poterie (Age de la Pierre au Métal), se développe lentement à partir de 7000 B.P. Dès le début, la chasse en forêt est associée à l'exploitation de Canarium schweinfurthii. Vers 4000 B.P. une industrie avec haches à gorge, lames et poterie a émergé. Dans une continuité technologique surprenante, cette culture survivra à l'Age du Fer. L'arboriculture est suggérée par l'importance et la diversification des arbres exploités durant l'Age de la Pierre au Métal et l'Age du Fer. Des comparaisons régionales montrent que, entre 5000 et 2500 B.P., une culture originale se développe dans les Grassfields et le bassin de la Cross River.     

Pollen analysis of core DS7-1SC (Dead Sea) showing intertwined effects of climatic change and human activities in the Late Holocene

The Dead Sea sediment holds the archives of a complex relationship between ever-changing nature and ancient civilisations. Here the detailed pollen analyses of core DS7-1SC (off-Ein-Gedi) are presented for the first time. The record covers the last 2500 years. The facies changes from halite (when no freshwater flows in the Dead Sea) to laminites (when rainfall provides sufficient inflow for the Jordan and subsidiary rivers) a couple of times through the record. The pollen diagram (supported by the facies change) shows a wetter Roman-Byzantine period, which allowed intensive arboriculture and a wetter period at the end of the XIXth and beginning of the XXth centuries, the latter in good relation with historical and instrumental data. Based on radiocarbon chronologies on several pollen diagrams along the western Dead Sea shore, the transition to drier climates and the transition to pastoralism are suggested to take place between a few decades before the Islamic period and close to this transition.     

Morphometric Analysis of Camelid Remains from the Alero Deodoro Roca (ADR) Site (Córdoba,Argentina). An Attempt to Characterise Body‐Size Variability in Sierras Pampeanas Australes Region

This paper focuses in the morphometric analyses of Lama guanicoe remains recovered from the hunter–gatherer archaeological site Alero Deodoro Roca, located at Sierras Pampeanas Australes region (Córdoba Argentina), an area that has little information on the body‐size variability of these artiodactyls. Because of the sparse osteometric data in the region, we focused on determining inter‐intraspecific differentiation of wild camelids through corroborated osteometric techniques and multivariate statistical analyses of proximal phalanges. Our results showed a clear interspecific differentiation between modern vicuñas and archaeological specimens. We could also distinguish at least three guanaco size groups (small, medium and large) with the archaeological remains from the late Holocene (3000–3600 bp ) of the site, presenting medium‐size characteristics. Finally this paper aims at establishing a first approach in the characterisation of guanaco body size in the mountainous region of Córdoba. Copyright © 2016 John Wiley & Sons, Ltd.     

The Role of Bubo virginianus magellanicus as Rodent Bone Accumulator in Archaeological Sites: A Case Study for the Atuel River (Mendoza,Argentina)

Micromammalian bone assemblages from modern pellets of the strigiform Bubo virginianus magellanicus, from the upper Atuel River (southern Mendoza, Argentina), were taphonomically analysed. The results allow us to place B. v. magellanicus in the category of intermediate modification (Category 2). This sample has also been compared with results from other members of this genus, in order to classify B. v. magellanicus as a taphonomic agent. The participation of the Bubo species in archaeological accumulations has been documented, but in Argentina, the role of B. v. magellanicus has been reported up to the present. It is partly because of the sequence of one archaeological site in the south of Mendoza Province called Laguna El Sosneado‐3 (LS‐3). However, considering the absence of a current taphonomic model of this owl, this participation was mentioned as a hypothesis. In the current investigation, archaeological and modern samples have been compared. The results indicate that the skeletal element assemblages recovered from LS‐3 were accumulated by strigiform birds. Taphonomical evidence of light modifications on units I and IV indicates that Tyto alba (Category 1) was probably the main species involved in these units, whereas the taphonomical evidence on skeletal element assemblages recovered from units II and III suggests the action of a strigiform with a major category of modification such as B. v. magellanicus.

Stone Tool Forms and Functions: A Morphometric Analysis of Modern Humans' Stone Tools From Song Terus Cave (Java,Indonesia)

Stone industries from the beginning of the Holocene of South‐East Asia are difficult to characterize typo‐technologically. We apply modern morphometrics to informal pieces to complement usewear analysis and gain a better understanding of the relation between forms and functions. Both the log shape ratio (LSR) based on linear measurements and elliptical Fourier analysis (EFA) based on 2D outlines are used to analyse a sample of 2372 stone artefacts from Song Terus cave (Java, Indonesia). The results show that no specific form corresponds to a specific function or vice versa. Nevertheless, among used artefacts, EFA highlighted several shape tendencies.     

Subsistence variations and landscape use among maritime hunter-gatherers. A zooarchaeological analysis from the Beagle Channel (Tierra del Fuego,Argentina)

Changes in the exploitation of resources among prehistoric hunter-gatherer-fishers of the Beagle Channel (Southern South America) are examined in this paper. Archaeological investigations show the prevalence of maritime hunter-gatherer organization throughout the occupation of the region (ca. 6400 BP – 19th century). Notwithstanding, variations in the exploitation of different kind of animal resources have been detected, and a concomitant reorientation in the landscape use is then inferred. Zooarchaeological evidence from five shellmiddens is analyzed here: evenness measures and relative abundance prey types are used to evaluate such adjustments. Results indicate the major utilization of coastal and terrestrial ecozones and the predominance in the exploitation of mammals (pinnipeds and guanacos) in ancient occupations. While, during the Late Holocene an expansion in ranges of maritime mobility for subsistence is detected, which was associated with an increase in the representation of birds and fish in the zooarchaeological record.     

Millerocaulis zamunerae sp. nov. (Osmundaceae) from Jurassic,geothermally influenced,wetland environments of Patagonia,Argentina

Sagasti, A.J., García Massini, J., Escapa, I.H., Guido, D.M. & Channing, A., August 2016. Millerocaulis zamunerae sp. nov. (Osmundaceae) from Jurassic geothermally influenced wetland environments of Patagonia, Argentina. Alcheringa 40, xxx–xxx. ISSN 0311-5518

A new species of Millerocaulis Erasmus ex. Tidwell emend. Vera is defined based on several permineralized stems recovered from geothermally influenced chert deposits in the Middle–Late Jurassic La Matilde Formation (Santa Cruz, Argentina). Millerocaulis zamunerae sp. nov. is characterized by the presence of an ectophloic dictyoxylic siphonostele, inner parenchymatic and outer sclerotic cortices, homogeneous sclerotic ring in the petiole bases, two masses of sclerenchyma lining the concavity of the petiolar vascular bundle, petiolar inner cortex with sclerenchyma strands in the outermost petiole cycles and stipular wings having one large and several smaller sclerenchyma bundles. Millerocaulis zamunerae inhabited geothermal wetlands and other hot-spring-related sedimentary facies associated with the La Bajada epithermal deposit. Reference to active geothermal wetlands, analogous living plants and other fossil hot spring ecosystems suggest the plant’s tolerance of physico-chemical stressors including elevated temperature, pH, salinity and phytotoxic metals/metalloids. Millerocaulis zamunerae thrived in wetlands preserved in the Jurassic geothermal systems of Santa Cruz Province, the same kind of environment in which Equisetum thermale Channing et al. was recorded previously.

Developmental Defects in the Spine: Initial Findings in Archaeological Cases from Córdoba Highlands (Argentina)

Congenital disorders are pathologies rarely found in archaeological cases. In recent years, however, there has been an increase in the number of reported cases, and a growing interest in understanding their development and implication as genetic markers within certain collections. In the central region of Argentina, researchers have begun to focus on issues related to the health of prehispanic populations from a bioarchaeological perspective. Between 1999 and 2012 our research group recovered, by rescue archaeological activities, a total number of 62 individuals from different archaeological sites in the province of Córdoba, from which only three individuals with pathologies classified as congenital were recorded (4.83%). Radiocarbon and contextual information sets these individuals in the late Holocene (2156 ± 86 and 920 ± 20 ¹⁴C years BP). Hence, this work aims at presenting two pathological conditions deriving from congenital developmental abnormalities that arise during the first three months of pregnancy: (a) Klippel–Feil syndrome (type II) which was suffered by the individuals from the sites of Guasmara and El Vado, and (b) central sagittal fissure of the vertebral body or ‘butterfly vertebra’ as in the case of one individual from La Calera. We also analyse other lesions in these skeletons that may be associated with the conditions mentioned above, and we provide a thorough interpretation from an osteobiographical perspective.

Palaeoenvironmental reconstruction of La Olla,a Holocene archaeological site in the Pampean coast (Argentina)

The evolution of littoral palaeoenvironments in the southern Pampas region of Argentina towards the end of the early Holocene and the beginning of the mid Holocene is discussed, and the formation processes of the archaeological site of La Olla are analysed. This site is located in the intertidal zone of the present beach and is remarkably well-preserved. The human occupation at the site has been dated at between 7400 and 6480 yrs BP, and is interpreted as a place for the processing and consumption of the southern fur seal (Arctocephalus australis) and southern sea-lion (Otaria flavescens). It is concluded that biostabilization by microbial mats of the sedimentary structures and archaeological remains that developed and are present on the tidal flat prevented their erosion by wind, turbulence currents and waves. This is what has permitted the exceptional preservation of the site. On the basis of the analyses of one of the sectors of the site it can be concluded that the sedimentary succession of the La Olla site is the result of the coastal environmental changes during the early–mid Holocene in the pre-maximum transgressive episode. During this interval a tidal flat developed on the Pleistocene abrasion platform. Human occupation occurred during the formation of mixohaline marsh, an upper intertidal–lower supratidal zone ecosystem.
