Late Cambrian (Iverian,Jiangshanian) fossils from the Professor Range area,Western Tasmania

Abstract

Late Cambrian (Iverian, Jiangshanian) agnostoids and trilobites are described from two localities in the Professor Range area of western Tasmania. The fossils occur within a thick folded flysch succession of siltstone, mudstone, quartzwacke sandstone and siliceous conglomerate that forms the lower part of the Owen Group correlatives in this area. The flysch succession has a conformable and probable gradational contact with the underlying Mt Read Volcanics and is abruptly overlain by the siliceous pebble-cobble conglomerate correlated with the Middle Owen Conglomerate of the West Coast Range. The stratigraphically lower southern locality contains the agnostoids Pseudagnostus sp. and Agnostinae gen. et sp. indet. plus the polymerid trilobites Parabolina sp., Hedinaspis sp. cf. H. regalis and Eugonocare sp. The northern locality contains the agnostoids Rhaptagnostus sp. and Pseudagnostus sp. plus the polymerid trilobites Hedinaspis sp. cf. H. regalis, Ketyna? sp. 1, Ketyna? sp. 2, and Cermatops sp. It is possible that most specimens of the cosmopolitan genus Hedinaspis belong in the type species, H. regalis.

After Utopia: Leftist imaginaries and activist politics in the postsocialist world

ABSTRACT

In this introduction to special issue ‘After Utopia: Leftist Imaginaries and Activist Politics in the Postsocialist World’, we explore the theoretical implications for thinking about activism as a form of historically situated practice in the former socialist world. Building on insights from the papers included in this issue, which draw on ethnographic research in Ukraine, Armenia, Bosnia and along the Balkan refugee route, our introduction considers both the fragility and resilience of leftist imaginaries in the aftermath of lost utopian dreams of socialism and the betrayed promises of post 1989 democratic transformation. We do so in four moves, (i) by offering a reframing of postsocialism as a problem-space of historical and political consciousness; (ii) by interrogating the figure of the activist in its self-conscious and ethnographically embedded guises; (iii) by heeding Sherry Ortner’s call to think beyond ‘dark anthropology’ and finally, (iv) by considering what it might mean to imagine, and model, political alternatives in both activist and scholarly work.
