Fixation of the type species of the genus Protoretepora de Koninck, 1878 (Bryozoa,Fenestrata)

Wyse Jackson, P.N., Reid, C.M. & McKinney, F.K., iFirst article, 2011. Fixation of the type species of the genus Protoretepora de Koninck, 1878 (Bryozoa, Fenestrata). Alcheringa, 1–2. ISSN 0311-5518.

The type species of the Palaeozoic bryozoan genus Protoretepora de Koninck, 1878 was originally fixed as Fenestella ampla Lonsdale in Darwin, 1844, but this taxon has been shown to belong to the bryozoan genus Parapolypora Morozova & Lisitsyn, 1996 Morozova, I. P. and Lisitsyn, D. V. 1996. Revision of the genus Polypora. Paleontologicheskii Zhurnal, 1996(4): 38–47. [English translation: Paleontological Journal30(5), 530–541] [Google Scholar]. The original type species designation for Protoretepora de Koninck, 1878 is set aside, and in accordance with Article 70.3 of the International Code of Zoological Nomenclature (4th edition, 1999) the nominal species Protoretepora crockfordae Wyse Jackson, Reid & McKinney, 2011 from the Permian of Tasmania, Australia is herein fixed as the type species.     

A short-snouted trematosauroid (Tetrapoda,Temnospondyli) from the Early Triassic of Australia: the oldest known trematosaurine

The trematosauroid temnospondyl Tirraturhinus smisseni gen. et sp. nov. from the Arcadia Formation of central Queensland, Australia, is described on the basis of its rostrum. This is the first trematosaurine (short-snouted) trematosauroid from Australia, and is considered to be most closely related to Tertrema acuta from Spitzbergen. Tirraturhinus smisseni occurs alongside lonchorhynchine (long-snouted) trematosauroids in the Arcadia Formation; the co-occurrence of both trematosauroid morphotypes in that fauna is repeated in a number of non-marine Early Triassic faunas elsewhere in Pangaea. The Arcadia Formation is probably Griesbachian (earliest Triassic), so that T. smisseni is the oldest known trematosaurine.     

The Heritagescape: Looking at Landscapes of the Past

Heritage sites are one of the most visible, accessible and tangible manifestations of heritage and are also some of the essential building blocks of heritage. Yet we are still without a sense of how they operate over time and in relation to each other. This paper will introduce the notion of the ‘heritagescape’ as a means of interpreting and analysing heritage sites as unique social spaces that offer an experience of the past. In contrast to previous attempts to investigate these places, the heritagescape offers the means to focus both on the underlying similarities and also on the relationships of different sites to each other. As such, heritagescape offers a coherent and overarching methodology by which to identify the universal processes and elements that characterise heritage sites and will allow us to take our examination of heritage as a cultural phenomenon into the future.     

Media Responsiveness to 'Old' and 'New' Politics Issues in Australia

Attempts to transform political agendas are closely associated with the role of the media in shaping perceptions, reflecting programs of political organisations, influencing institutional practices and applying pressure on divergent interests. By examining the role of an influential news magazine in voicing concerns about welfare and environment policies over a 40-year period, this article tests arguments about the salience of 'old' and 'new' politics issues as well as the changing character of debates about these questions in efforts to create a sustainable, competitive and global economy. Apart from examining the capacity of the media to change their storylines (or ways of thinking about an issue), the article considers how they attempt to draw on credible news sources to substantiate their reports.
