Reappraisal of Austrosaurus mckillopi Longman, 1933 Longman, H.A., 1933. A new dinosaur from the Queensland Cretaceous. Memoirs of the Queensland Museum 10, 131–144. [Google Scholar] from the Allaru Mudstone of Queensland, Australia’s first named Cretaceous sauropod dinosaur. Alcheringa 41, 543–580. ISSN 0311-5518

Austrosaurus mckillopi was the first Cretaceous sauropod reported from Australia, and the first Cretaceous dinosaur reported from Queensland (northeast Australia). This sauropod taxon was established on the basis of several fragmentary presacral vertebrae (QM F2316) derived from the uppermost Lower Cretaceous (upper Albian) Allaru Mudstone, at a locality situated 77 km west-northwest of Richmond, Queensland. Prior to its rediscovery in 2014, the type site was considered lost after failed attempts to relocate it in the 1970s. Excavations at the site in 2014 and 2015 led to the recovery of several partial dorsal ribs and fragments of presacral vertebrae, all of which clearly pertained to a single sauropod dinosaur. The discovery of new material of the type individual of Austrosaurus mckillopi, in tandem with a reassessment of the material collected in the 1930s, has facilitated the rearticulation of the specimen. The resultant vertebral series comprises six presacral vertebrae—the posteriormost cervical and five anteriormost dorsals—in association with five left dorsal ribs and one right one. The fragmentary nature of the type specimen has historically hindered assessments of the phylogenetic affinities of Austrosaurus, as has the fact that these evaluations were often based on a subset of the type material. The reappraisal of the type series of Austrosaurus presented herein, on the basis of both external morphology and internal morphology visualized through CT data, validates it as a diagnostic titanosauriform taxon, tentatively placed in Somphospondyli, and characterized by the possession of an accessory lateral pneumatic foramen on dorsal vertebra I (a feature that appears to be autapomorphic) and by the presence of a robust ventral mid-line ridge on the centra of dorsal vertebrae I and II. The interpretation of the anteriormost preserved vertebra in Austrosaurus as a posterior cervical has also prompted the re-evaluation of an isolated, partial, posterior cervical vertebra (QM F6142, the ‘Hughenden sauropod’) from the upper Albian Toolebuc Formation (which underlies the Allaru Mudstone). Although this vertebra preserves an apparent unique character of its own (a spinopostzygapophyseal lamina fossa), it is not able to be referred unequivocally to Austrosaurus and is retained as Titanosauriformes indet. Austrosaurus mckillopi is one of the oldest known sauropods from the Australian Cretaceous based on skeletal remains and potentially provides phylogenetic and/or palaeobiogeographic context for later taxa such as Wintonotitan wattsi, Diamantinasaurus matildae and Savannasaurus elliottorum.

ROCK ART SITES IN JAMAICA AND THEIR ETHNOGRAPHIC INTERPRETATION

26 sites with Pre‐Columbian (Taíno) rock art are known in Jamaica, most with petroglyphs only, but there are four with painted images, and three of these are discussed: Mountain River Cave, Potoo Hole, and Spot Valley Cave. In addition, an account is given of the Warminster rock shelter, which has petroglyphs described as among the best remaining in Jamaica. Spot Valley Cave was newly surveyed in 2005, with the help of the Jamaican Caves Organization, and in the same year a rescue operation to restore the Warminster petroglyphs was carried out, in cooperation with Dr Johannes Loubser. Comparisons are made, where appropriate, to Taíno artefacts in different materials, and also to Pre‐Columbian images on other islands in the Caribbean, notably Puerto Rico. The interpretation of the Taíno images, in Jamaica and elsewhere, relies to a considerable extent on the “Account of the Antiquities of the Indians”, compiled by Fray Ramón Pané in 1494–1498, on the express instructions of Columbus. Whatever the shortcomings of a narrative compiled by an outsider, we would be much worse off without it.     

Globalization and the closing of the universe of discourse: the contemporary relevance of Marcuse's “Marxism”1

This paper assumes that there is something in the logic of the capitalist mode of production such that, in the words of Marx and Engels' Communist Manifesto, it “must nestle everywhere, settle everywhere, establish connections everywhere,” giving a “cosmopolitan character to production and consumption in every country.” It assumes, that is, that there is an inherent tendency in capitalism to seek to globalize. Further, it is argued that one can plausibly claim that the capitalist mode of production has succeeded, or is succeeding, in globalizing against the countervailing forces of the managing state and organized labor. It is argued that this development represents, to use Marcuse's words, something like a “closing of the universe of discourse” or a “paralysis of criticism” and the emergence of a “society without opposition,” but in a context, in crucial respects, fundamentally different from that analysed by Marcuse in the 1960s.     

Communal Tenure and Rural Poverty: Land Transactions in Svosve Communal Area,Zimbabwe

The idea of communal tenure has formed a key plank in the rural governance of Zimbabwe since independence, but its retention following the Fast Track land reforms of 2000–2002 perpetuates a distinction between ‘commercial’ land governed by a land market and ‘communal’ land on which market transactions are illegal. This article draws on recent research in Svosve Communal Area to examine the dynamics of land access and their implications for rural poverty in Zimbabwe. The authors argue that, as in many other parts of Africa, access to land governed by customary authority in Svosve is increasingly commoditized via informal, or ‘vernacular’, sales or rental markets. In failing to acknowledge and address this commoditization of land, the ‘communitarian’ discourse of customary land rights that dominates the politics of land in Zimbabwe — as elsewhere in much of Africa — undermines, rather than protects, the livelihoods of the rural poor.     

Innovation Advantages of Cities: From Knowledge to Equity in Five Basic Steps

This paper explores the reasons why cities are often major centres of innovation, even in some less favoured regions and countries. It starts with an anatomization of the dominant factors that explain why key less favoured settings developed 'new economy' clusters through institutional interaction with Silicon Valley. The analysis concludes that public research resources and private commercialization funding are central, supported by a wide array of private but few public innovation support services. It then examines a number of cases from cities in less favoured regions and countries where innovation has occurred. The conclusions are that the research-venture capital model is present and explains innovation in each case. However, in some cases public venture capital has to substitute for private due to market failure, or a phenomenon termed 'Silicon Valley Offshore' has been induced. Cities are innovative where they concentrate the desired scientific and investment knowledge capabilities.
