Tertiary megafossil flora of Maslin Bay,South Australia: a preliminary report

The Maslin Bay flora of South Australia is of lower Middle Eocene age and contains diverse, well preserved angiosperm assemblages. It has yielded 2700 specimens belonging to approximately 200 leaf taxa.

Physiognomic analysis (sensu Webb, 1959; Wolfe 1970) indicates greatest similarity to extant Simple Mesophyll Vine Forest and Complex Notophyll Vine Forest found currently in Queensland.

Preliminary taxonomic studies have confirmed the presence of taxa closely resembling Podocarpus (Podocarpaceae), Agathis (Araucariaceae), Fatsia (Araliaceae) and Banksia (Proteaceae). Microfloral analysis of the deposit confirms the presence of the latter three families, but suggests far greater occurrence of Proteaceae than the number of leaf specimens of this family indicates. Nothofagus pollen is the dominant type, although leaves of this genus are absent from collections. Based on sedimentation, physiognomy and systematic studies of leaves and fungi (Lange, 1969) it is concluded that the Maslin Bay region supported tropical to subtropical rain forest during the lower Middle Eocene.     

The Taphonomy of Resource Intensification: Zooarchaeological Implications of Resource Scarcity Among Bofi and Aka Forest Foragers

Zooarchaeological analyses often rely on bone fragmentation, cut marks, and other taphonomic indicators to bolster interpretations of resource intensification that are based on observed changes in prey types and frequencies. While these taphonomic indicators are assumed to be good proxy measures of processing effort, this assumption is based on inadequate actualistic data and analysts often conflate one or more taphonomic indicators as manifestations of the same process. In this paper, we present zooarchaeological data from two villages occupied by Central African forest foragers with very different foraging efficiencies. These data provide the first case where known disparities in diet breadth and foraging efficiency are matched with prey assemblages and taphonomic attributes. Observational and quantitative data show differences between the villages in diet breadth and access to high-ranked prey, but specific taphonomic indicators such as cut mark distribution and intensity do not match predictions generated from models of resource intensification. We propose that linking different taphonomic processes to resource scarcity and intensification can provide powerful adjunctive information. However, because different processing outcomes may be associated with different kinds of resource intensification in response to different kinds of scarcity, we need to strengthen the validity of purported taphonomic indicators with more rigorous independent studies.     

Rancière,Derrida, and Egalitarian Politics in Pseudo-Dionysius

Abstract

Using the work of Jacques Rancière, I argue for an egalitarian reading of the political hierarchy in Pseudo-Dionysius. I first analyze various historical attempts to derive a political theory from Pseudo-Dionysius in the work of Juan Miguel Garrigues, René Roques, and Dominic O’Meara. I then turn to Jacques Derrida's attempt to distinguish deconstruction from negative theology, and consider especially the political effects of this strategy. I argue that Derrida's attempt to undermine Psuedo-Dionysius's system from within is unsuccessful, and suggest instead that Rancière provides the conceptual tools to identify an egalitarianism within Dionysian political theory     

Small prey hunting technology and zooarchaeological measures of taxonomic diversity and abundance: Ethnoarchaeological evidence from Central African forest foragers

Archaeological analyses of faunal assemblages often rely on rationale derived from the prey choice model to explain temporal and spatial changes in taxonomic measures of diversity and/or abundances. In this paper, we present analyses of ethnoarchaeological observations and bone assemblages created by Central African Bofi and Aka forest foragers which show that different small prey hunting technologies target specific suites of prey and that hunters vary their technological choice depending on their foraging goals. Analysis of ethnoarchaeological bone assemblages produced by the Bofi and Aka shows that variability in target prey can create spatially distinct, but contemporaneous, faunal assemblages with different diversity values and abundance indices. These data reveal important variation in how individuals within a contemporary human population rank prey and challenge current assumptions about the meaning of diversity and abundances measures in archaeological contexts. We argue that the use of diversity and abundance indices can obscure important intrasite variability in prehistoric foraging effort and suggest strategies that might enhance current techniques.     

Criminalising commercial surrogacy in Canada and Australia: the political construction of ‘national consensus’

This article examines the language used to justify a criminal prohibition on commercial surrogacy in Canada and Australia. I demonstrate that legislators in each country framed commercial surrogacy as an area over which there was national ‘consensus’ because of uniquely Canadian and Australian values. This was an effective political strategy, but for different reasons in each country: in Canada, because it fit with frames surrounding healthcare and anti-commercialisation, and in Australia, because the distinction between ‘altruistic’ and ‘commercial’ surrogacy mapped onto broader themes of altruism in Australian society. This suggests that the political use of national frames is especially successful when it taps into pre-existing narratives of what constitutes unacceptable behaviour in a given polity, and when it is attached to criminal prohibitions.     

A Portuguese East Indiaman from the 1502–1503 Fleet of Vasco da Gama off Al Hallaniyah Island,Oman: an interim report

Two Portuguese naus from Vasco da Gama's second voyage to India, left behind to disrupt maritime trade between India and the Red Sea, were wrecked in May 1503 off the north‐eastern coast of Al Hallaniyah Island, Oman. The ships, Esmeralda and São Pedro, had been commanded by da Gama's maternal uncles, Vicente and Brás Sodré, respectively. A detailed study and scientific analysis of an artefact assemblage recovered during archaeological excavations conducted in Al Hallaniyah in 2013 and 2014 confirms the location of an early 16th‐century Portuguese wreck‐site, initially discovered in 1998. Esmeralda is proposed as the probable source of the remaining, un‐salved wreckage.
