A late Miocene–early Pliocene Mihirung bird (Aves: Dromornithidae) from Victoria,southeast Australia

Park, T. & Fitzgerald, E.M.G. September 2012. A late Miocene–early Pliocene Mihirung bird (Aves: Dromornithidae) from Victoria, southeast Australia. Alcheringa 36, 427–430. ISSN 0311-5518.

An incomplete tarsometatarsus identified as an indeterminate species of Dromornithidae is described from the upper Miocene–lower Pliocene shallow marine Black Rock Sandstone at Beaumaris, Victoria, Australia. This isolated specimen represents one of the few pre-Pleistocene dromornithids with a well-constrained geologic age. Additionally, it is one of the few pre-Quaternary dromornithid fossils recorded from southeast Australia. Comparisons with known dromornithid taxa suggest that the Beaumaris dromornithid is distinct from previously established species. This hitherto unknown species of dromornithid in the late Neogene of southeastern Australia cautions against deriving evolutionary patterns solely on the basis of fossils from northern Australia.     

Verzeitlichungs- und Historisierungstendenzen in der frühen Geologie und Paläontologie

Steno described in 1669 geological sections which were interpreted as the result of a series of earlier events. Steno used actuogeological methods. This was the first step towards temporalizing nature. Steno was succeeded by a lot of other researchers from different European countries. It is amazing to see, that “actualism” was widespread during the 18th century. The next step was the discovery that fossils are extinct beings (Ray, Hooke and others). Using methods of comparing anatomy W. Hunter (forerunner of Cuvier) could prove in 1769 that the Mastodon is an extinct vertebrate. The work of Soulavie in France (1780) is stressed. He held in his hand the key for solving the problem of index-fossils. About 1800 the importance of fossils for stratigraphy and describing a history of the earth was recognized. Theories and hypotheses were needed to explain the fossil documents (strange shells in older strata and higher developed mammals in younger strata). All these theories couldn't propose a feasible mechanism for the change of beings during the history of the earth. But it could be said, that all fossils proove a history of life and the earth i. e. a progressive development in one sense, a development which is not reversible.     

The southernmost records of Anhingidae and a new basal species of Anatidae (Aves) from the lower–middle Miocene of Patagonia,Argentina

New bird fossils from the Santa Cruz Formation (lower–middle Miocene), Santa Cruz Province, Patagonia, Argentina, are described. They represent an indeterminate species of the extinct anhingid Macranhinga and a new genus and species of basal Anatidae Ankonetta larriestrai. The record of the giant darter Macranhinga constitutes the southernmost record for the family, and expands the known stratigraphic range of the genus, previously restricted to the upper Miocene. Based on an analysis of the fossil anhingid record from South America, we hypothesize that giant darters disappeared from South America in the early Pliocene due to climatic deterioration, regression of marine and freshwater environments, the arrival of placental carnivorous mammals, and also probably by competition with phalacrocoracid cormorants. The new anatid Ankonetta is based on an incomplete but informative tarsometatarsus, with superficial similarities to extant Dendrocygna. A brief overview of several fossil ducks from the Patagonian Cenozoic concludes that most pre-Pliocene examples belong to non-anatine taxa, indicating that plesiomorphic ducks were the dominant anseriforms in those times, a pattern also evident on other continents.     

"This war for men's minds": the birth of a human science in Cold War America

The past decade has seen an explosion of work on the history of the human sciences during the Cold War. This work, however, does not engage with one of the leading human sciences of the period: linguistics. This article begins to rectify this knowledge gap by investigating the influence of linguistics and its concept of study, language, on American public, political and intellectual life during the postwar and early Cold War years. I show that language emerged in three frameworks in this period: language as tool, language as weapon, and language as knowledge. As America stepped onto the international stage, language and linguistics were at the forefront: the military poured millions of dollars into machine translation, American diplomats were required to master scores of foreign languages, and schoolchildren were exposed to language-learning on a scale never before seen in the United States. Together, I argue, language and linguistics formed a critical part of the rise of American leadership in the new world order - one that provided communities as dispersed as the military, the diplomatic corps, scientists and language teachers with a powerful way of tackling the problems they faced. To date, linguistics has not been integrated into the broader framework of Cold War human sciences. In this article, I aim to bring both language, as concept, and linguistics, as discipline, into this framework. In doing so, I pave the way for future work on the history of linguistics as a human science.     

"The dangers of this atmosphere": a Quaker connection in the Tavistock Clinic's development

During the Second World War, through innovations in officer selection and group therapy, the army psychiatrists John Rickman and Wilfred Bion changed our understanding of leadership. They showed how soldiers under stress could develop real authority through their attentiveness to each other. From contrasting experiences 25 years earlier each had seen how people in groups are moved by elemental forces that undermine judgement and thought. This article arose from my experiences as a trainee at the Tavistock Clinic, where the method of reflective work discussion, giving individuals seated in a circle the choice to speak or to remain silent, seemed similar to a Quaker meeting. Many decades later, I found that this association had a basis in fact. Among other influences on Bion -- a childhood in India, distinguished service in the First World War, and a surgical apprenticeship with Wilfred Trotter -- there is a little-acknowledged Quaker source, in John Rickman, for Bion's radical work in the army that led to new methods of training and organizational consultancy in the postwar Tavistock.     

SIENESE ‘ARCHAIC’ MAJOLICA: A TECHNOLOGICAL STUDY OF CERAMIC BODIES AND COATINGS*

The aim of the present study is to reconstruct the production technology of Sienese ‘archaic’ majolica in the early decades of the 14th century ad . The integration of archaeological data with archived data revealed the presence of numerous workshops, suggesting that the Sienese tradition of majolica production was well developed up until the end of the 16th century. Sixty‐seven uncoated and coated waste products were analysed. The ceramic bodies were examined by OM, XRDp, SEM–EDS, XRF, ICP–OES, ICP–MS and INAA. The coatings (enamels and glazes) were analysed by SEM–EDS and Raman microspectroscopy. The results showed that ceramics were rejected due to poor control of the firing temperature (technological wastes), faulty production technology (wastes of uncertain classification) and accidents (post‐firing wastes). Finally, the analyses revealed extreme homogeneity of the ceramic bodies, indicating the continued use of the same raw material over the whole period studied.     

Foucault's and Arendt's "insider view" of biopolitics: a critique of Agamben

This article revisits Arendt's and Foucault's converging accounts of modern (bio)politics and the entry of biological life into politics. Agamben's influential account of these ideas is rejected as a misrepresentation both because it de-historicizes biological/organic life and because it occludes the positivity of that life and thus the discursive appeal and performative force of biopolitics. Through attention to the genealogy of Arendt's and Foucault's own ideas we will see that the major point of convergence in their thinking is their insistence upon understanding biological thinking from the inside, in terms of its positivity. Agamben's assessment of modern politics is closer to Arendt's than it is to Foucault's and this marks a fascinating point of disagreement between Arendt and Foucault. Whereas Arendt sees the normalizing force of modern society as being in total opposition to individuality, Foucault posits totalization and individuation as processes of normation, which casts a light upon the relative import they place upon politics and ethics.     

First report of a South American short-faced bears' den (Arctotherium angustidens): palaeobiological and palaeoecological implications

Here we report the first example of associated short-faced bear fossils from South America. The specimens represent three individuals referable to the Ensenadan (early to middle Pleistocene) species Arctotherium angustidens (Ursidae, Tremarctinae), the giant South American short-faced bear. Although the fossil record of short-faced bears in South America is very rich, they have not previously been recorded in association. These three individuals were found in a cave during quarry exploitation. We suggest that these bears represent the first record of a family group and open the discussion about cave utilization and hibernation or torpor by South American short-faced bears.     

The application of 3D‐microprofilometry as a tool in the surface diagnosis of fossil and sub‐fossil vertebrate hard tissue. An example from the Pliocene Upper Laetolil Beds,Tanzania

Non‐contact optical 3D‐profiling instruments are often used in the study of surface modifications on fossil mammalian bone. The advantage of optical laser scanning for the study of fossil and sub‐fossil bone is its non‐contact nature, allowing the investigation of fragile and poorly preserved surfaces. The high resolution and fast measuring rate of this method make it an alternative to scanning electron microscopy (SEM) investigation if topography is to be visualized. This study analyses clusters of incisions in a suid humeral fragment from the Pliocene Upper Laetolil Beds. The marks show a characteristic crest structure that is also frequently found in mandible marks produced by the Australian termite species Mastotermes darwiniensis. The marks from the Laetolil Beds are, therefore, interpreted as also being caused by insect mandible action. An as yet unknown large insect species capable of modifying bone with their mandibles is thus postulated in the palaeohabitat represented by the hominid‐bearing Upper Laetolil Beds.

"The Human Condition" as social ontology: Hannah Arendt on society, action and knowledge

Hannah Arendt is widely regarded as a political theorist who sought to rescue politics from "society," and political theory from the social sciences. This conventional view has had the effect of distracting attention from many of Arendt's most important insights concerning the constitution of "society" and the significance of the social sciences. In this article, I argue that Hannah Arendt's distinctions between labor, work, and action, as these are discussed in "The Human Condition" and elsewhere, are best understood as a set of claims about the fundamental structures of human societies. Understanding Arendt in this way introduces interesting parallels between Arendt's work and both classical and contemporary sociology. From this I draw a number of conclusions concerning Arendt's conception of "society," and extend these insights into two contemporary debates within contemporary theoretical sociology: the need for a differentiated ontology of the social world, and the changing role that novel forms of knowledge play in contemporary society as major sources of social change and order.     

The first fossil sea turtles (Testudines: Cheloniidae) from the Cenozoic of Australia

An isolated dentary and costal identified as cf. Pacifichelys and Cheloniidae indet., respectively, are described from the upper Miocene–lower Pliocene Black Rock Sandstone of Beaumaris, Victoria, Australia. These remains represent the first fossil evidence of sea turtles from the Cenozoic of Australia. Neither of the fossils can be referred to living genera, indicating that extinct cheloniids occurred in southeast Australian coastal waters for at least part of the late Neogene. Thus, the taxonomic composition of the current sea turtle fauna of Australia was apparently established within the last five to six million years.     

A new fossil genus of forest wallaby (Marsupialia,Macropodinae) and a review of Protemnodon from eastern Australia and New Guinea

A new macropodine genus and species, Silvaroo bila, is described from the Pliocene Chinchilla Sand of Queensland. The generic concept of Protemnodon is reviewed, and it is concluded that two Pliocene species previously placed in that genus (bandharr and buloloensis) belong in Silvaroo. Species of Silvaroo resemble the modern forest wallabies of Papua New Guinea (species of Dorcopsis and Dorcopsulus) and also bear close phenetic resemblance to the late Miocene Dorcopsoides fossilis. Forest wallabies are not known from mainland Australia after the middle Pliocene, but occur in the late Pliocene and Pleistocene of New Guinea.     

A late Miocene–early Pliocene baleen whale assemblage from Langebaanweg,west coast of South Africa (Mammalia,Cetacea, Mysticeti)

Govender, R., Bisconti, M. & Chinsamy, A., June 2016. A late Miocene–early Pliocene baleen whale assemblage from Langebaanweg, west coast of South Africa (Mammalia, Cetacea, Mysticeti). Alcheringa 40, xxx–xxx. ISSN 0311-5518

Knowledge of post-Eocene cetaceans from Africa is very poor with almost nothing known about this group from southern Africa except for the diverse trawled ziphiids. Langebaanweg, a locality yielding prolific Miocene–Pliocene fossils on the southwestern Cape coast of South Africa, preserves terrestrial and marine biotas in juxtaposition. Palaeoenvironments vary from a marine shoreline to a lagoon and estuary and later a shallow marine environment and include several microhabitats. Fragmentary preservation of the cetacean skeletons suggests that they were transported before burial. This first detailed analysis of the Mio-Pliocene mysticete fossils from Langebaanweg uses the petrotympanic region to taxonomically identify specimens. Three un-named species of balaenopterid Mysticeti represent a Plesiobalaenoptera-like form, but it is premature to erect a new taxon based on this fragmentary material. The remaining material is too poorly preserved to be identified with confidence.

Micropalaeontological investigation of late Pliocene marine sediments at Sangiran,Central Java

The Upper Kalibeng Formation and the marine intercalations of the lower part of the Pucangan Formation at Sangiran, Central Java, contain more than 30 taxa of fossil calcareous nannoplankton. These fossils indicate a Late Pliocene age for the Upper Kalibeng and lower Pucangan. The Upper Kalibeng Formation is assigned to calcareous nannoplankton Zone NN 16 (3.25 – 2.3 m.y.). The lower Pucangan Formation is within the NN 16 to NN 18 interval (3.25 – 1.65 m.y.).

Illustrations and the genesis of Barrett and Yonge's "Collins pocket guide to the sea shore" (1958)

Twenty nine items of correspondence from the mid-1950s discovered recently in the archives of the University Marine Biological Station Millport, and others made available by one of the illustrators and a referee, shed unique light on the publishing history of "Collins pocket guide to the sea shore". This handbook, generally regarded as a classic of its genre, marked a huge step forwards in 1958; providing generations of students with an authoritative, concise, affordable, well illustrated text with which to identify common organisms found between the tidemarks from around the coasts of the British Isles. The crucial role played by a select band of illustrators in making this publication the success it eventually became, is highlighted herein. The difficulties of accomplishing this production within commercial strictures, and generally as a sideline to the main employment of the participants, are revealed. Such stresses were not helped by changing demands on the illustrators made by the authors and by the publishers.     

Changes in the Abundance and Diversity of Proteaceae in South‐western Australia: a Review of an Integrated Palaeoenvironmental Study

South‐western Australia is a globally significant hotspot of Proteaceae diversity. This review reports on changes in the abundance and diversity of Proteaceae in south‐western Australia. Using palynology, the data were obtained from three sediment sequences from the Eocene, Pliocene and Holocene, as well as a modern pollen rain study, in the context of a vegetation history framework. The total percentages of Proteaceae pollen in pollen counts indicate that the number of Proteaceae in the vegetation are highest at present, slightly lower, yet still high in the Eocene, reduced by the Pliocene and lowest in the Holocene. It was found that Proteaceous genera can contribute up to 50% of the total modern pollen rain. Sediment from Lake Lefroy showed Nothofagus‐dominated rainforest occurred in the Middle to Late Eocene. Proteaceae species were at least as diverse as today, contributing up to a maximum of 42% of the total pollen rain, and varying across small lateral distances. A laminated Pliocene age sequence from Yallalie confirmed other studies that south‐western Australia was covered by a rich vegetation mosaic consisting of heath and wet rainforest elements. Proteaceae species were a consistent component of the counts, although diversity and abundance (maximum 5%) were low. A Holocene record from Two Mile Lake, near the Stirling Range, recorded little environmental change. Proteaceae species were noted in low abundance, at a maximum of 3.5% of the total pollen count. It is likely that both changing pollination mechanisms and changes in associated vegetation are important in determining the dispersal of Proteaceous pollen.

Amplitudes of orbitally induced climatic cycles and patterns of hominin speciation

Palaeoanthropologists and archaeologists have long invoked climate change to explain aspects of human evolution. Collection of new climatic and environmental data combined with new fossil discoveries and methodological improvements continue to make exploration of this link a vital endeavour in studying human evolution. The current study employs a global climatic dataset and a rigorously compiled catalogue of hominin first and last appearance dates to test the effects of changes in temperature on hominin speciation and extinction. Through the use of wavelet analysis and bandpass filters the eccentricity, obliquity, and precession components of the studied climatic record are extracted and tested independently for associations with patterns of speciation and extinction. Results suggest that all three components may play a role in speciation events, but that only the obliquity cycle shows a statistically significant relationship with extinction events. It is suggested that, whilst climatic factors could contribute to the appearance of new hominin species, subsequent competition between these species may lead to their extinction.     

Significance of diadematid echinoid ossicles in micropalaeontological samples,Miocene–Pliocene of Indonesia

Fragments of diadematoid echinoids from the early and middle Miocene, and late Miocene–Pliocene, respectively, of Java, Kalimantan and Sulawesi, Indonesia, are identified as diadematid spp. indet. (radioles from all sites) and Centrostephanus sp. (an interambulacral plate; early Miocene, Java). The radioles are probably a mixture of Diadema ± Centrostephanus ± Echinothrix. This is the first report of identifiable fossil diadematoid remains from Indonesia and demonstrates that these echinoids, so common in modern reef environments, were present in the Neogene of the region. Even though classified in open nomenclature, Centrostephanus sp. nevertheless provides further evidence for the Cenozoic record of a genus in which the only nominal species are of Late Cretaceous and Holocene age.
