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.

Early astogeny in the Catenicellidae (Bryozoa,Cheilostomata)

Examples of early astogeny in the species Carinatocella harmeri (Stach), Costaticella hastata (Busk) and Claviporella aurita (Busk) are discussed. The primary zoid differs in each species and if found fossil, only in C. hastata could this zoid be recognised as a bryozoan fragment. Analogous development in other Bryozoa is discussed.     

Conflicts Over Trees and Waves on Siberut Island

ABSTRACT The paper describes some recent developments with respect to logging operations and the tourist industry on the island of Siberut (West Sumatra, Indonesia). It discusses these developments from the perspective of the notions of equitable access and benefit sharing and prior informed consent. These are often referred to as basic principles in dealing with external intervention within the territory of indigenous peoples. After the initial logging boom during the 1970s and 1980s about half of the island was declared a nature reserve in the early 1990s. All logging operations were terminated. Backpack tourism started to develop more or less simultaneously, stimulated by the lure of a Stone Age culture on a tropical paradise island. This contributed greatly to the efforts to safeguard the island's rich biodiversity. Recently, however, a new form of logging started on the island, with a university as concession holder. But also a new kind of tourism discovered Siberut: its waves are supposed to be of excellent quality and allow for first‐class surfing. As a result of regional autonomy and the process of democratisation in Indonesia, the local people are not willing to accept these new forms of resource use without at least sharing in their benefits. This paper is based on extensive periods of fieldwork on Siberut over the past twenty years.     

Italy and Australia: a relationship made and unmade by immigration

Australia's new-found post-colonial ‘independence’ in 1901 initially required it to continue to hold on to the apron strings of its colonial master. After World War II, these needs changed, as did the geopolitical power of the leading nations. For Australia, there would be the need to secure its borders, build its labour power, find security arrangements, and adhere to a cold war framework in its geographical region. The USA and the Asian region fell into Australia's sphere of interest. Italy, on the other hand, was a nation of contrasting interests and perspectives. Besides being located in Europe, the post-war period defined Italy by its participation in the concept of a European community and an entirely different set of allies, concerns and trajectories, which made it position itself in a different orbit than that of Australia. Australia's changing economic and social needs required a new and vast migration program in 1947, which would change the dynamics of its relationships. Enter Italy. The two countries now had common destinies in relation to migration—Australia needed people to help build its country, whilst Italy encouraged its impoverished rural population to emigrate to this distant and foreign land. A relationship was born.     

Restructuring women’s work; labour market and household gender regimes in the Greater Latrobe Valley,Australia

This article examines the impact of economic restructuring on gender relations. It examines the implications of labour market change for households within a region, in this case the Greater Latrobe Valley, Victoria, Australia. The argument is that the unchanging gender structures of the labour market constrain the intentions and efforts of individuals within households to significantly alter household gender relations. The analysis considers how restructuring has reshaped the regional labour market since 1996, changing opportunities for both men’s and women’s employment. Despite these changes, the regional labour market continues to be underpinned by a ‘male breadwinner’ gender regime and significant occupational and industrial gender segregation. Drawing on four vignettes, the analysis shows that the impetus towards greater gender equality in the household is constrained by a stagnant and stable labour market gender regime.     

Governing the inner “periphery.” Spatial security governance of the Highlands in Papua New Guinea since the colonial period

Specific regions and places are considered particular threatening and dangerous by state authorities. There, the state regularly enacts security in harsh and violent ways. In this article, I develop a pragmatic spatial framework, inspired by and combining elements from post-statist geography and Critical Security Studies, to explain patterns of spatial security governance in regions with competing local authorities and regular violence. I particularly argue for more historical analysis on the emergence and legacies of spatial security governance to understand its persistence and consequences. I illustrate the framework with an empirical investigation of the spatial security governance of the Highland regions in Papua New Guinea, and its role as a dangerous inner “periphery” for the central state since the late colonial period. The patterns of security governance in the Highlands, like the declaration of emergency zones in case of regional warfare, the use of violent punitive expeditions by mobile forces, accompanied by a securitizing discourse, have remained remarkably similar. While the post-colonial state aimed at a break with the colonial past, the spatial security governance of the Highlands has remained an important source for the legitimization of state rule and state formation. Governing the inner “periphery” is constructed as the responsibility of the state, which has been historically entangled in the “violent geographies” in the Highlands.
