Earp, C., 29 January 2019. Costulatotheca schleigeri (Hyolitha: Orthothecida) from the Walhalla Group (Early Devonian) at Mount Pleasant, central Victoria, Australia. Alcheringa. Alcheringa 43, 220–227. ISSN 0311-5518

A number of hyolith fragments (including one operculum), found in Early Devonian marine turbidites at Mt Pleasant, near Alexandra, central Victoria, are described as Costulatotheca schleigeri gen. et sp. nov., the first confirmed record of the order Orthothecida in the Devonian of Australia. Index fossils found at this locality (Uncinatograptus sp. cf. U. thomasi and Nowakia sp. ex gr. N. acuaria) indicate an age of Pragian or earliest Emsian. The taphonomy of rare rafted shelly fossils indicates that flysch deposition occurred in a very-low-energy environment into which there were occasional bursts of high-energy turbidites carrying allochthonous fossils from shallower water.

Smith, P.M., Brock, G.A. & Paterson J.R. 20 September 2019. Shelly fauna from the Cambrian (Miaolingian, Guzhangian) Shannon Formation and the SPICE event in the Amadeus Basin, Northern Territory. Alcheringa 44, 1–24. ISSN 0311-5518

A low-diversity assemblage of linguliformean brachiopods, hyoliths, molluscs, bradoriid arthropods and echinoderms (ten taxa in total) is documented from the upper Shannon Formation (Cambrian, Miaolingian, Guzhangian; Mindyallan) in the Ross River Syncline and Todd River Anticline area, NE Amadeus Basin, central Australia. Taxa described include: the linguliformean brachiopods Treptotreta jucunda Henderson & MacKinnon, 1981, Opisthotreta sp., Stittia? sp., an undetermined acrotretid and an undetermined linguloid; the molluscs Kobayashiella? heritagensis Webers, Pojeta & Yochelson, 1992 (a paragastropod), and Apoptopegma joyceae sp. nov. (a rostroconch); the bradoriid Mongolitubulus sp.; Hyolithida gen. et sp. indet.; and isolated echinoderm plates. All fauna (including previously documented trilobites) from the upper Shannon Formation disappear at the beginning of a ~5‰ positive shift in δ13C, identified as the Steptoean Positive Isotopic Carbon Excursion (SPICE). Despite previous links between SPICE and a global extinction, as well as the disappearance of all faunal elements in the uppermost Shannon Formation, certain taxa reported herein range through the event elsewhere in the world. The occurrence of Treptotreta jucunda and Kobayashiella? heritagensis in younger (Furongian) deposits indicates these species survived the SPICE extinction event. This study advocates for more systematic and comprehensive sampling through stratigraphic intervals where the SPICE event occurs, especially for range data of complete faunas (rather than individual taxonomic groups), to facilitate a more complete picture of diversity trends through this important phase.

The article addresses gendered power asymmetries within indigenous communities of early Soviet Siberia and their shifts during the transitional period between the Russian Empire and the totalitarian Soviet state. The concept of entangled relational spaces is the main analytical tool of this article. Seeking to overcome identity-based essentialisms, the article deconstructs gender identity and demonstrates how it can be articulated and interpreted in different relational spaces. It extends the argument that oppressions are produced by various social categories (intersectionality) by adding that a single social category may beget various forms of oppression and that heterogeneous gender asymmetries are produced and manifested across different relational spaces. Evidence deriving from predominantly indigenous sources authored by women enabled the discussion of gendered power asymmetries in economic, legal, and political spaces produced by corresponding relations. Economic and demographic crises, which the indigenous peoples of Siberia endured in the 1910s–1920s, reduced gendered power asymmetries in economic spaces making women less dependent on men. On women's initiative the shifts then spread to legal spaces and, with the support of the Bolshevik government, affected political spaces. These shifts were closely connected to the early Soviet attempts at dialog with indigenous people, decolonizing Siberia and liberating indigenous women, and gave way to instrumental policies.  相似文献

An osteological collection of dogs from an aboriginal population settlement (Nadym Gorodok) in Western Siberia is described in this work. There were numerous bones (more than 1600) well preserved in the permafrost cultural layer, including almost complete skeletons of dogs of various ages. Craniological characteristics and reconstructions of the size and functions of the aboriginal dog were studied. The analysis of the finds showed that there was a large number of dogs in Nadym Gorodok in the 14–18th centuries AD. Dogs were bred on site in the settlement. During the 4 centuries, middle-size dogs of the same build were kept in Nadym Gorodok. In size and general skull shape, the dogs were similar to the modern laika breed. The dogs were used mainly for hunting. During a hunt, dogs stalked prey and pulled sledges as a draft animal. There were no herding dogs.  相似文献

Research into the Upper Paleolithic of northeastern Asia began in the 1940s. Recent work has led to the discovery of numbers of sites, some of them more than 30,000 years old, which are assigned to the D'uktai culture. The material recovered from these sites indicates relationships between the D'uktai culture and other cultures in Europe, Japan, Korea, China, and North America. For the most part, however, these similarities do not result from a spread of cultural traits from Europe into Asia. Instead, most of them reflect local development of the Upper Paleolithic, within both Asia and Europe, out of local Middle Paleolithic industries, which were themselves originally similar in technology and typology.  相似文献

Rich settlement and burial evidence from the Baikal/Angara region in Central Siberia provides one of the most promising opportunities in the global boreal forest for studying Holocene foragers. The Neolithic and Early Bronze Age prehistory of the region is known to western scholars only through a few English translations of the works of A. P. Okladnikov. Since the publication of Okladnikov's model, the region has witnessed large-scale archaeological fieldwork that has produced abundant quantities of new evidence. Moreover, the model has been partly invalidated by extensive radiocarbon dating. Research advances over the last couple of decades have augmented the area's previous reputation but have also revealed the need for new theoretical perspectives and modern analytical techniques.  相似文献

Our understanding of the prehistory of the Upper Yenisei area is based on several key multilayered sites, which provide an excellent opportunity for the investigation of long-term culture change and the reconstruction of culture history. The earliest traces of prehistoric people in the region date to the Sartan glacial. Ui I is dated to ca. 22,000–17,000 B.P. and belongs to the middle phase of the Yenisei Upper Paleolithic, predating the period of the Final Paleolithic Afontova culture (16,000–10,000 B.P.). The Early Holocene period remains little known; there is only one assemblage (the lower cultural layer of Sosnovka Golovan'skaya) which may be attributed to the Epipaleolithic. In the seventh and sixth millennia B.P., the aceramic Early Neolithic (the uppermost cultural horizons of Maina and Ui II, Ust'Khemchik 3, etc.) was widespread and was replaced by the Late Neolithic Verkhneeniseisk culture in the fifth millennium B.P. This was succeeded by the Eneolithic Afanas'eva culture at the end of the fifth millennium B.P. and, later, by the Bronze Age Okunev culture (until the twelfth century B.C.). From the eighth to the second centuries B.C., Scythian cultures flourished in the area, until the invasion of the Huns. All of these stages of the Holocene culture sequence are represented in the stratified site of Toora-Dash.  相似文献

Here I present a critical evaluation of the analysis conducted by Graf [Graf, K.E., 2009. “The Good, the Bad, and the Ugly”: Evaluating the radiocarbon chronology of the middle and late Upper Paleolithic in the Enisei River valley, south-central Siberia. Journal of Archaeological Science 36, 694–707] of the Paleolithic radiocarbon (14C) dataset for the Upper Paleolithic sites in the Yenisei River basin of Central Siberia. Graf applied a rating system to the corpus of existing 14C data for the region, and announced some new 14C dates. The results obtained, however, are highly biased due to several factors, including prejudice concerning the higher accuracy of the AMS technique in 14C dating and that 14C dates from the same cultural component should overlap with plus–minus two sigmas; ambiguities with the subdivision of the Lateglacial period; artificially high sample selection criteria; incomplete factual material; and unjustifiable and misleading statements on the 14C dating of fossil bones and the issue of Last Glacial Maximum human presence in Siberia. As a result, the conclusions made by Graf [Graf, K.E., 2009. “The Good, the Bad, and the Ugly”: Evaluating the radiocarbon chronology of the middle and late Upper Paleolithic in the Enisei River valley, south-central Siberia. Journal of Archaeological Science 36, 694–707] are unconvincing. New analysis is necessary in order to improve the quality of treatment of the original data for the Upper Paleolithic 14C chronology in the Yenisei River basin.  相似文献

The palaeontological data on mammal remains from two Middle Palaeolithic (ca. 125 000 years ago – 27 200 BP) and 34 (ca. 34 000–12 000 BP) Upper Palaeolithic cultural complexes in the upper part of the Yenisei River basin (southern Siberia) are considered. General features of the faunal assemblages are established. Several issues are discussed, including (a) changes in species composition through time and palaeoenvironmental implications of the zooarchaeological records; (b) patterns of human exploitation (hunting) of mammals; (c) issue of mammoth hunting and (d) possibility of domestication of dog in the late Upper Palaeolithic in the Yenisei River basin.

Considerable progress has been made in recent years in the study of the Lower and Middle Paleolithic of northern Asia. There is growing evidence for initial human occupation before 700,000 years ago—as early as elsewhere in Asia—and for a very early adaptation to the arctic desert environment. New models of Lower Paleolithic settlement involve expansion and reduction of occupation in response to climatic variation, rather than simple colonization followed by steady occupation. The Middle Paleolithic of northern Asia is better documented, including actual finds of archaicHomo sapiens. The transition to the Upper Paleolithic seems to involve the survival of earlier cultural traits, but the mechanisms and processes are not well understood. Further significant knowledge concerning these periods awaits the development of common methodologies for classification and analysis.  相似文献

The area of the Middle and Upper Yenisei is one of the most important concentrations of Paleolithic sites in Northern Asia. More than 200 localities, belonging to various stages of the Paleolithic, are now known. The initial phase of the Late Paleolithic is represented by Malaya Syiya, which is dated to approximately 34,000–33,000 B.P. The middle phase of the Late Paleolithic is marked by the blade industries of Early Sartan age (24,000–18,000 B.P.), as at Shlenka, Tarachikha, Ui I, and elsewhere. At 18,000–16,000 B.P., these were replaced by the Final Paleolithic Afontova and Kokorevo cultures, although some of the earlier blade industries continued into this period (Golubaya I).  相似文献

Iron Age societies of the eastern Eurasian steppe are traditionally viewed as nomadic pastoralists. However, recent archaeological and anthropological research in Kazakhstan has reminded us that pastoralist economies can be highly complex and involve agriculture. This paper explores the nature of the pastoralist economies in two Early Iron Age populations from the burial grounds of Ai-Dai and Aymyrlyg in Southern Siberia. These populations represent two cultural groups of the Scythian World – the Tagar Culture of the Minusinsk Basin and the Uyuk Culture of Tuva. Analysis of dental palaeopathology and carbon and nitrogen stable isotopes suggests that domesticated cereals, particularly millet, and fish formed a major component of the diet of both groups. The findings contribute to the emerging picture of the nuances of Early Iron Age subsistence strategies on the eastern steppe.  相似文献

Radiocarbon Chronology of the Siberian Paleolithic   总被引:2,自引:0,他引:2  
We have compiled 462 C-14 determinations for 120 Paleolithic and Mesolithic sites from Siberia and the Russian Far East. The Mousterian sites are dated to ca. 46,000–28,500 BP. The Middle–Upper Paleolithic transition dates to ca. 43,300–28,500 BP. Although there are a few earlier sites, most of the Upper Paleolithic sites are dated to the time interval between ca. 34,000 BP and 10,000 BP. The earlier Upper Paleolithic stage is characterized by macroblade technology and is radiocarbon-dated to ca. 34,000–20,000 BP. The earliest microblade technology occurs in the late stage of the Upper Paleolithic, dated to ca. 23,000–20,000 BP, but the majority of microblade sites is dated to ca. 20,000–11,000 BP. The Final Paleolithic (Mesolithic) sites date to ca. 12,000–6000 BP. At ca. 13,000–11,000 BP, the earliest Neolithic appeared in both the Russian Far East (Amur River basin) and the Transbaikal. The Paleolithic–Neolithic transition occurred ca. 13,000–6000 BP.  相似文献

Previously developed regression formulae for estimating body mass in dogs and wolves based on cranial and mandibular dimensions are evaluated using modern canid specimens of known weight at death. Some of these equations proved reliable, but others have large standard errors of estimate and likely produce unreliable mass estimates. New sets of equations for estimating body mass in dogs and wolves are produced using our datasets, including a set of equations developed from combining the dog and wolf biometric data into a single population. The resulting regression equations allow body mass to be estimated from a series of cranial and mandibular dimensions with relatively low errors. Further, our datasets include larger numbers of specimens of larger ranges of body mass than in these previous studies. When the equations are applied to a suite of dogs and one wolf from Eastern Siberia, several patterns emerge. First, hunter–gatherers' dogs in this region vary widely in terms of body size, even within a limited geographic area and time period. Some were quite large, similar in size to modern Siberian huskies. Second, pastoralists' dogs are less variable in terms of body mass, but this may reflect the nature of our samples. In particular, pastoralists' dogs nearly all were sacrificed juvenile dogs, some of which appear to have been eaten. These dogs seem to have been approached adult body size when they were selected for sacrifice. Finally, our findings help to highlight the need for further refinement in methods used to study ancient canid remains. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

In the early seventeenth century, learned Muscovites, as they set themselves to the task of working out a Russian and Orthodox vision of their place in the world, began to read, translate and modify the atlases produced by their slightly earlier European counterparts: Ortelius, Mercator, Blaeu and others. The Russian solution to this geographical puzzle grew out of and reflected a sense of the tsardom's unique location and imperial ambitions. The position that Muscovite cosmographers and geographers generally assigned to their realm was a connective one: the tsardom lay proudly between points on the globe; it linked vastly different lands and peoples; and it contained within its purview a heterogeneous assortment of peoples, faiths, tongues and cultures. In this article, I examine the different manifestations of that thinking and of Muscovite ideological conceptions of empire in two widely separated parts of the tsardom—Siberia, at some length, and then, more briefly, Ukraine/Belarus—and explore how their ideological frameworks affected the subject populations of those two areas.  相似文献
