Oldest meiolaniid turtle remains from Australia: evidence from the Eocene Kerosene Creek Member of the Rundle Formation,Queensland

Poropat, S.F., Kool, L., Vickers-Rich, P. &; Rich, T.H., September 2016. Oldest meiolaniid turtle remains from Australia: evidence from the Eocene Kerosene Creek Member of the Rundle Formation, Queensland. Alcheringa 41, XX–XX. ISSN 0311-5518.

Fossil meiolaniid turtles are known only from South America and Australasia. The South American record is restricted to the Eocene, and comprises two genera: Niolamia and Gaffneylania. The Australasian meiolaniid record is more diverse, with three genera known (Ninjemys, Warkalania and Meiolania); however, the oldest known specimens from this continent are significantly younger than those from South America, deriving from upper Oligocene sediments in South Australia and Queensland. Herein, we describe the oldest meiolaniid remains found in Australasia to date. The specimens comprise a posterior peripheral, a caudal ring, and an osteoderm, all of which derive from the middle–upper Eocene Rundle Formation of The Narrows Graben, Gladstone, eastern Queensland. Despite their fragmentary nature, each of these specimens can be assigned to Meiolaniidae with a high level of confidence. This is particularly true of the partial caudal ring, which is strongly similar to those of Niolamia, Ninjemys and Meiolania. The extension of the Australasian meiolaniid record to the Eocene lends strong support to the hypothesis that these turtles arose before South America and Australia detached from Antarctica, and that they were consequently able to spread across all three continents.

“Who's Going to Man the Factories and be the Sexual Slaves if we all get PhDs?” Democratizing Knowledge Production,Pedagogy, and the Detroit Geographical Expedition and Institute

Identifying a policy/activism dichotomy in critical geography debates about political engagement, this paper uses the Detroit Geographical Expedition and Institute (DGEI) as a way to think about teaching as an alternative response for left geographers. By focusing on the DGEI's commitment to expanding access to knowledge production, not simply the dissemination of knowledge, the paper highlights the radical potential of a key form of academic work, teaching, but reconceived as a radically democratic project aimed at breaking the cycle of expert knowledge production. This potential has largely been marginalized in the development of radical geography, but it has been carried forward, latently, in much of the best thinking about the democratic possibilities of knowledge production, namely feminist discussions of situated knowledges. The paper argues that revisiting the DGEI helps to push those discussions further and restore teaching as a central concern of radical geography's project of promoting social justice.
