Large freshwater plesiosaurian from the Cretaceous (Aptian) of Australia

Benson, R.B.J., Fitzgerald, E.M.G., Rich, T.H. & Vickers-Rich, P., 2013. Large freshwater plesiosaurian from the Cretaceous (Aptian) of Australia. Alcheringa 37, 1–6. ISSN 0311-5518

We report a large plesiosaurian tooth from the freshwater early–middle Aptian (Early Cretaceous) Eumeralla Formation of Victoria, Australia. This, combined with records of smaller plesiosaurian teeth with an alternative morphology, provides evidence for a multitaxic freshwater plesiosaurian assemblage. Dental and body size differences suggest ecological partitioning of sympatric freshwater plesiosaurians analogous to that in modern freshwater odontocete cetaceans. The evolutionarily plastic body plan of Plesiosauria may have facilitated niche differentiation and helped them to exclude ichthyosaurs from freshwater environments during the Mesozoic. However, confirmation of this hypothesis requires the discovery of more complete remains.

‘I've had it with them!’ Younger migrant women's spatial practices of conformity and resistance

This article examines how younger migrant women from Turkey maneuver the public and private spaces of their everyday lives in a neighborhood in Germany, and how they challenge and affirm the patriarchal practices and gender norms that husbands, fathers, and older migrant women seek to impose within and outside private homes. Younger migrant women selectively comply with gendered and generational norms of veiling and dress, while at the same time also reworking gender roles, and avoiding and transgressing masculinist spaces. Younger migrant women's practices and spatial representations in mental maps reveal the complex entanglements of compliances and resistance, and dispel simple assumptions of being overwhelmingly victimized by their potentially violent men that are so prominent in contemporary Western societies.     

A Microfacies Toolkit for Revealing Linkages Between Cultural Discontinuities and Exceptional Geogenic Events: the Tell Da’de Case Study (NE Syria)

High-resolution multi-archive studies have been promoted to reveal abrupt discontinuities that would express rapid social reactions (days to decades) to sudden exceptional geogenic phenomena (climatic, volcanic, tectonic, geomorphic, or cosmic). We expose here how we have adopted this approach for examining the causal linkages between a series of cultural discontinuities encountered through the cultural deposits of Da’de (Syria) and cosmic airbursts. Cosmic events, known to be rare, erratic, and unpredictable, are traced by exceptional debris that formed from aerosols when violently compressed during entry through the earth atmosphere of hypervelocity cosmic collider. They consist of singular organo-mineral materials in the form of volatile-rich hydrocarbon fuel with resistant metal-rich carbonaceous composites and colorful polymers. The archaeological sequence comprises Da’de phases 0 to III that represent a nearly continuous accumulation for 1,000 years during the Pre-pottery Neolithic period (ca. 9,900–8,900 years bp) and two short-term occupation phases during the pre-Halaf (Da’de IV) and early Bronze Age periods (Da’de V). Study of the exceptional debris in virgin soils and occupation deposits at Da’de has allowed to distinguish an intact debris assemblage that pulverized at the ground following an airburst (type 1 natural singular signal) with the ones that have been processed by humans (type 2 anthropic singular signal). Type 1 singular organo-mineral materials were found intact at the contact of the virgin soil with the earliest Pre-pottery Neolithic A (PPNA) occupation layers (Da’de phase 0, area [SB]), at the top part of the virgin soil with the PPNA occupation layers (Da’de phase Ia, area [B]) and just under the lower slabs of the EB III/IV burials (Da’de phase V, area [SB]). This has allowed to establish a strict contemporaneity between cosmic airbursts and remarkable historical events: initial settlement at phase 0, establishment of the magnificent communal building at phase 1, EBIII/IV cemetery after a long period of abandonment. Evidence for the collection of the singular materials (type 2) and meticulous processing of the related hydrocarbon fuel in occupation floors, earthen construction, coloring materials, and objects have been traced from the initial settlement (phase 0) through the successive cultural periods. This correlation has revealed a long-lasting transmission of the value of memorial natural resources which were only available from time to time in the surroundings. The close timing between changes in the use of the singular organo-mineral materials (preparation techniques, types of by-products) and cultural phases has enabled us to identify social discontinuities which correlate to distinctive geogenic events and search of the related exceptional resources. Based on the long-term record from Da’de, cosmic airbursts are suggested to be considered as a new class of dual-discontinuous signal of historical dimension, which have led to sudden (days to months) geogenic shifts in the availability of singular fuel resources and, simultaneously, to rapid cultural responses in their exploitation and use, depending on reactivity of local landscapes to the induced changes at short time scales (decades).     

Constitutionalism or Staatssreich? Bismarck,Crown Prince Frederick William,Crown Princess Victoria and the Succession Crisis of 1880-85

Though Otto von Bismarck exercised great power as Chancellor of the German Empire, historians have overlooked the extent to which it was threatened during the 1880s by the imminent accession of Crown Prince Frederick William. The article focuses on the means by which Bismarck strove to maintain his power, and how many of his plans were thwarted by the crown prince. The heir to the throne had to also fend off his wife's campaign to enact radical liberal reforms during her husband's coming reign. The ability of the crown prince to resist the campaigns of both his wife and Bismarck shows that his influence was indeed considerable, and that estimates of Bismarck's power are in need of revision.     

Long-term agrarian landscapes in the Troodos foothills,Cyprus

We investigate the temporal and environmental relationships between the terraced hill slopes of Politiko-Koloiokremmos and the adjacent Bronze Age settlement of Politiko-Troullia in foothills of the Troodos Mountains, central Cyprus. Mapping of 102 stone walls on Koloiokremmos is compared with 66 walls farther afield on Cyprus to create a six-part terrace typology. Sherd counts from 174 2-m radius collection circles over approximately 20 ha on Troullia and Koloiokremmos were used to create interpolated sherd density surfaces revealing distinctly different patterns of land use for four major archaeological eras between the Cypriot Bronze Age and Medieval Period. We compared sherd density patterns according to terrace types, length, slope and vegetation cover determined by SAVI (Soil-Adjusted Vegetation Index) from Ikonos and Quickbird satellite imagery.The most robust sherd patterning indicates Prehistoric Bronze Age settlement at Troullia, as confirmed by soil resistivity and excavation, and multi-period land use on Koloiokremmos immediately upslope of the village that may be associated with agricultural terracing. Scattered sherd concentrations indicate later use of this landscape as an agricultural hinterland for the Iron Age city of Tamassos. Sherds and a down slope spread of roof tiles from the Roman through Medieval periods suggest an isolated structure near the crest of Koloiokremmos. Longer terraces correlate with greater vegetation cover and are interpreted as agricultural, while shorter terraces, apparently for erosion control and arboriculture, are significantly related to Prehistoric Bronze Age sherd patterns. Our results suggest that coordinated analysis of archaeological, geographical and remotely sensed environmental data associated with terraced landscapes can be used to infer long-term patterns of agricultural land use.
