A Morphological Classification of Roots and Tubers and its bearing on the Origins of Agriculture in Southwest Asia and Europe

The classification of roots and tubers into morphological categories is often confusing and more of a hindrance than a help to archaeobotanical analysis. As such, a new classification, based on the potential for vegetative propagation, is suggested, and the terms it uses are briefly defined. The different categories of roots and tubers are then discussed with reference to the archaeological record and the origins of agriculture in Southwest Asia and Europe.     

Identification of wood from archaeological sites in the American Southwest. I. Keys for gymnosperms

Keys for the identification of gymnosperm wood remains from archaeological sites in the American Southwest are presented. Wood identification and analysis are briefly discussed.     

Avian egg-shell from archaeological sites

Avian egg-shell occurs fairly commonly on archaeological sites, particularly in alkaline deposits. It is rarely studied in detail. Egg-shell structure is described briefly below and features which may be of value for identification purposes are discussed. Egg-shells from 14 archaeological sites are tentatively identified as goose, domestic fowl, duck and guinea fowl. It seems likely that confident identification should ultimately be possible using a combination of features. This should yield information complementary to osteological evidence for the history of the utilization of birds and their eggs.     

Computer analysis of an inconsistent data source: the case of probate inventories

Computers are becoming increasingly popular for analysing data in historical geography and are being applied to an extending range and variety of historical sources. The methods described in most computer texts for geographers and historians, using the langueage allied to punched cards, are only suitable for numeric data which are in a standardized and consistent form. Rather than attempting to apply these methods to sources not organized in this way, it is more sensible to tailor a technique to a particular class of data.This paper considers some advantages of computer analysis, using English probate inventories as an example. Limitations of conventional methods are discussed and a technique is described for dealing with sources whose information is inconsistent between records. The method relates the logical structure of inventories to the storage and use of data by the computer, and considers the forms data can take for input to the machine. An example from the analysis of inventory data prepared by this method is briefly presented, describing two aspects of agricultural change in East Anglia between 1580 and 1740.     

The architecture of Permian glossopterid ovuliferous reproductive organs

McLoughlin, S. & Prevec, R. 20 September 2019. The architecture of Permian glossopterid ovuliferous reproductive organs. Alcheringa XX, xxx–xxx. ISSN 0311-5518

A historical account of research on glossopterid ovuliferous reproductive structures reveals starkly contrasting interpretations of their architecture and homologies from the earliest investigations. The diversity of interpretations has led to the establishment of a multitude of genera for these fossil organs, many of the taxa being synonymous. We identify a need for taxonomic revision of these genera to clearly demarcate taxa before they can be used effectively as palaeobiogeographic or biostratigraphic indices. Our assessment of fructification features based on extensive studies of adpression and permineralized fossils reveals that many of the character states for glossopterids used in previous phylogenetic analyses are erroneous. We interpret glossopterid fertiligers to have been borne in loose strobili in which individual polysperms represent fertile cladodes of diverse morphologies subtended by a vegetative leaf or bract. Polysperms within the group are variously branched or condensed with ovule placement ranging from marginal to abaxial, in some cases occurring on recurved branchlets or in cupule-like structures. Glossopterid polysperms of all types are fringed by one or two ranks of wing-like structures that may represent the remnants of megasporophylls that were, ancestrally, developed on the fertile axillary shoot. Glossopterid fertiligers have similarities to the condensed bract/ovuliferous scale complexes of conifer cones, but comparisons with Mesozoic seed-ferns are hindered by insufficient data on the arrangement and homologies of the ovule-bearing organs of the latter group. Nevertheless, glossopterid polysperms differ from the ovuliferous organs of Mesozoic seed-ferns by longitudinal versus transverse folding, respectively.

St. Winefrede’s Well at Holywell,Flintshire

This paper reviews the use of hair pins in Roman Britain and examines in detail the ones made of metal which are found in the south. These are divided into twenty-five distinct and two miscellaneous groups, and the dating and distribution evidence for each is briefly discussed. It is shown that there is a distinction between those of the early and late Roman periods. The later first-and second-century groups tend to have restricted, regional distributions whereas the late third and fourth century ones are found throughout the area. There is also a change in length associated with time which is likely to be related to the way in which they were worn. An appendix on microfiche provides summary details of all the pins discussed.

Arena gets the growth syndrome

Abstract

Geographical educators can make useful contributions to the process of community development by helping local communities to achieve greater understanding of their environments. One way to do this is via the concept of regional synthesis, developed by, and shared with, the local residents of a community through the medium of a course which focuses on their local regional geography. A localised geography course was offered in 1977 to out ‐of‐school adults in the Kohala area of the island of Hawaii. The specific mechanics of the course are described here, and short‐term outcomes are evaluated. The potential of this form of ‘applied geography’ is briefly discussed.     

SEISMIC SOIL-STRUCTURE INTERACTION: BENEFICIAL OR DETRIMENTAL?

The role of soil-structure interaction (SSI) in the seismic response of structures is reex-plored using recorded motions and theoretical considerations. Firstly, the way current seismic provisions treat SSI effects is briefly discussed. The idealised design spectra of the codes along with the increased fundamental period and effective damping due to SSI lead invariably to reduced forces in the structure. Reality, however, often differs from this view. It is shown that, in certain seismic and soil environments, an increase in the fundamental natural period of a moderately flexible structure due to SSI may have a detrimental effect on the imposed seismic demand. Secondly, a widely used structural model for assessing SSI effects on inelastic bridge piers is examined. Using theoretical arguments and rigorous numerical analyses it is shown that indiscriminate use of ductility concepts and geometric relations may lead to erroneous conclusions in the assessment of seismic performance. Numerical examples are presented which highlight critical issues of the problem.     

The Aims of Knowledge: Emile Durkheim's Critique of American Pragmatism

The lectures on American pragmatism given by the French sociologist Emile Durkheim in 1913 in Paris were first published in French in 1955 and finally translated into English and published in 1983 as Pragmatism and Sociology. For obvious reasons they have attracted considerable attention from philosophers and sociologists, especially the latter, in both continental Europe and the English speaking world. Durkheim's motives in giving the lectures have been scrutinized, his interpretations of the pragmatists widely discussed and his criticisms of William James, John Dewey, and F. S. C. Schiller have met with mixed receptions. However, after years of scholarly discourse on his motives, interpretations and criticisms, there is no common agreement on the significance and meaning of Pragmatism and Sociology. We briefly address the disagreement over Durkheim's motives in the introductory section before turning to our interpretation in the body of the article. There we focus on his criticisms of the pragmatists’ views on the aims and nature of knowledge, which is a classic confrontation between French rationalism à la Durkheim and American pragmatism of the James/Dewey variant.     

Comments on relations West Norway ‐ Western Europe documented in petroglyphs

Dendrochronologic calibration of radiocarbon dates, which is of vital importance when such dates are compared with historical records, is discussed.

The nature and causes of variations in the past atmospheric radiocarbon content are briefly described. Different calibration curves are compared with available high‐precision data on radiocarbon in tree rings, and also with preliminary results from the joint efforts of U.S. scientists to establish an optimal calibration scheme.     

A New Approach to Identifying Bone Marrow and Grease Exploitation: Why the “Indeterminate” Fragments should not be Ignored

The economic importance of bone fat to past peoples is discussed and the ethnography of bone marrow and grease extraction is briefly outlined. Models for expected patterns of bone fracture and fragmentation, relating to the exploitation of bone marrow and grease, are described. Current methods for assessing bone fracture and fragmentation, in archaeological assemblages, are discussed and a new methodology is suggested. The importance of retaining and studying the “indeterminate” class of fragments is stressed. The new methodology employs a fracture freshness index (FFI) to study fracture type, and fragmentation is assessed through the separation of fragments into size classes and different bone types. An example application is given.     

Ascertaining an agent: using tooth pit data to determine the carnivore/s responsible for predation in cases of suspected big cat kills in an upland area of Britain

The identification of the involvement of a particular carnivore in the modification of bone assemblages concerns a number of fields of research including archaeological and palaeontological enquiry. Taphonomy provides a methodology by which bone assemblages can be analysed and interpreted and this is more often undertaken with archaeological or palaeontological assemblages. A taphonomic analysis is undertaken here in order to determine the perpetrator of predation attacks on domestic stock from a modern-day setting. Recently reported techniques using tooth marks preserved on bone surfaces made by known carnivores are successful at determining some class sizes of predators and are used here to determine the perpetrator(s). Although a class size of carnivore is readily identified by this methodology, a particular carnivore taxon is not. Tooth morphology and dental configuration are reported here as better criteria for identifying a particular taphonomic agent. Tooth pit dimensions are used here to identify the class size of carnivores involved, and tooth morphology and cusp spacing to suggest a medium sized felid and fox as taphonomic agents. The identification of the medium-sized felid may support observations and reports of alleged “big” cat kills in the area. The study has important implications for the interpretation of fossil sites where felids may have been involved in the modification of animal carcasses but are archaeologically invisible in terms of their fossil remains.     

A petrified cycad trunk from the Late Cretaceous of the Larsen Basin,Antarctica

Cetricycas antarcticus gen. et sp. nov. occurs in the Late Coniacian to Campanian Lachman Crags Member of the Santa Marta Formation, Marambio Group, James Ross Island, Antarctica. The petrified trunk comprises a thick pith containing thin and thick walled parenchymous cells, vascular traces surrounded by a thin layer of loose secondary wood. Medullary bundles arise inside the wood zone and pass outwards through multiseriate medullary rays. The trunk anatomy indicates assignment to the Cycadales, and the presence of medullary bundles indicates the affinities with a clade comprising Lepidozamia, Macrozamia, and Encephalartos. This clade is presently confined to Australia and Africa, but fossil representatives extend the geographic range to India, South America and now Antarctica.     

Patterns of pastoralism in later Bronze Age Kazakhstan: new evidence from faunal and lipid residue analyses

Current research themes relating to prehistoric Central Asian pastoralism are discussed, and the Neolithic to Bronze archaeological sequence in Kazakhstan is briefly outlined. The results of new faunal analyses of six later Bronze Age sites in Central and Northern Kazakhstan are presented. These studies are based upon the analysis of 63,529 bone fragments, of which 27,023 were identifiable to species and element. These assemblages are compared with 16 other sites in Central and Northern Kazakhstan, and the Trans-Ural region. The herd structures at the final Bronze Age site of Kent are discussed in detail. Analyses of absorbed lipid residues from four sites are also presented. In total, 140 pottery sherds were analysed, of which 73 provided sufficient residues for stable isotope ratio determinations. It is concluded that species proportions are highly variable regionally. Cattle are most prevalent in the forest steppe zone, whilst caprines become more common in semi-arid steppe regions. Proportions of horse are particularly variable, even within environmentally similar areas. Lipid residue results indicate the high prevalence of ruminant dairy products in pottery vessels, whilst faunal data from Kent suggests that cattle husbandry might have been particularly focussed on milk, in comparison with sheep and goats. The significance of horses within prehistoric pastoralism is discussed.     

A New and Unusual Landscaping Ideal: Joseph Addison's Contribution to Romanticism

Addison's landscape discussion in the famous 1712 Spectator essay on the pleasures of the imagination has often been regarded as the beginning of modern aesthetics. To see how this is the case but not in the way of conventional interpretations, it is important to remember the then revolutionary idea of “beauty without order” which Sir William Temple first discussed via the asymmetrical Chinese gardening style and which Addison enthusiastically endorsed in his horticultural reform agenda. Much more than the notions of beauty, greatness, and uncommonness which are the ostensible focus and usually noticed content of his essay and which are all derived from classical European aesthetics, it is this new and unusual love of things in their seeming irregularity and disorder, and the associated belief in their capability to work themselves out, that retrospectively seems to constitute Addison's most important contribution to English and European Romanticism.     

Late Ordovician linguliformean microbrachiopods from north-central Kazakhstan

An assemblage of well-preserved Devonian trilobites is described from limestones in Satun Province, southern Thailand. The biogeographic implications are briefly discussed. The fauna, which is of Early Devonian age, probably Emsian, includes Decoroproetus, Cornuproetus, Platyscutellum and two species of Reedops, one of which is new. No similar fauna has been described before from the Shan-Thai block. The fauna is a typical Hercynian assemblage with close specific comparisons with Turkey, Morocco and Bohemia.     

Identifying wine markers in ceramics and plasters using gas chromatography–mass spectrometry. Experimental and archaeological materials

The identification of the organic residues preserved in archaeological materials yields good insights into understanding food production, trade and consumption. Wine is one of the most important beverages produced, traded and consumed in the Mediterranean area. Consequently, it is important to identify its presence in ancient materials. Nevertheless, the identification of wine markers is still an object of discussion. We present here the results obtained from analysing different materials using gas chromatography/mass spectrometry (GC/MS), which allowed for the identification of tartaric acid and other markers of wine. The method was first tested on experimental and traditional materials that have been used until recently to store and/or produce wine and was then used for investigating archaeological materials. The experiments also involved the degradation of wine through cooking, drastic heating and burial for seven years. The results from the analysis of ceramic and plaster materials are discussed.     

Morphometric distinction between bilobate phytoliths from <Emphasis Type="Italic">Panicum miliaceum</Emphasis> and <Emphasis Type="Italic">Setaria italica</Emphasis> leaves

The development of identification criteria for crop plants based on phytoliths is of high relevance for archaeology, palaeoecology and plant systematics. While identification criteria are available for major food crops, these are mostly based on phytoliths from inflorescences, while other plant parts remain undetected. This paper focuses on bilobate phytoliths from leaves of Panicum miliaceum L. (common millet) and Setaria italica (L.) P. Beauv. (foxtail millet), two taxa that co-occur in regions of Asia and Europe since prehistory and regularly occur at archaeological sites in Eurasia. Leaves of the investigated taxa were systematically sampled to explore the variation of short cells and to collect 27 morphometric variables of bilobate phytoliths with newly developed open-source software. The data was analysed by discriminant analysis, analysis of variance and multiple comparison tests. The resulting morphometric data from five populations per species enables a distinction between the bilobate phytoliths of P. miliaceum and S. italica. Observed differences between populations within species affect only few parameters. This possibility to classify populations of bilobate phytoliths from P. miliaceum and S. italica leaves offers a new method for the detection and identification of these taxa in archaeology, amongst others.
