A new record of an aristonectine elasmosaurid (Sauropterygia,Plesiosauria) from the Upper Cretaceous of New Zealand: implications for the Mauisaurus haasti Hector, 1874 hypodigm

O’Gorman, J.P., Otero, R.A. & Hiller, N., 2014. A new record of an aristonectine elasmosaurid (Sauropterygia, Plesiosauria) from the Upper Cretaceous of New Zealand: implications for the Mauisaurus haasti Hector, 1874 Hector, J., 1874. On the fossil Reptilia of New Zealand. Transactions and Proceedings of the New Zealand Institute 6, 333–358. [Google Scholar] hypodigm. Alcheringa 38, 504–512. ISSN 0311-5518

An indeterminate aristonectine elasmosaurid is recorded from a lower Maastrichtian bed of the Conway Formation, Waipara River, South Island, New Zealand. The described specimen (CM Zfr 104), previously considered part of the hypodigm of Mauisaurus haasti, came from the upper part of the Alterbidinium acutulum biozone, the same zone from which the only well-known aristonectine from New Zealand, Kaiwhekea katiki, is recorded. The cervical vertebrae of CM Zfr 104 have the same distinctive features (i.e., with extremely broad rather than long centra) as those from previously recorded juvenile aristonectines from Argentina, Chile and Antarctica. This new record is congruent with the biogeographic relationships of Cretaceous marine amniotes from the Weddellian Palaeobiogeographic Province (i.e., Patagonia, western Antarctica, New Zealand and southeastern Australia). Therefore, this type of vertebra is regarded as a distinctive feature of the Weddellian aristonectine elasmosaurids.

Rock Stars and Bad Apples: Moral Economies of Alternative Food Networks and Precarious Farm Work Regimes

Alternative food networks face both challenges and opportunities in rethinking the role of precarious employment in food system transformation. We explore how alternative food networks in British Columbia, Canada have engaged with flexible and precarious work regimes for farmworkers, including both temporary migrant workers and un(der)paid agricultural interns. Based on in‐depth interviews, participant observation and document analysis, we find that alternative food actors often normalize a precarious work regime using a moral economy frame. This framing describes precarious farm employment as either a necessary challenge in the transition to sustainability, or merely involving a few individual “bad apple” farmers. Further, this framing involves an aversion to “one‐size‐fits‐all” regulation by the state in favor of consumer‐driven regulation of labor standards. Our analysis suggests that a moral economy framing can obscure systemic inequities in precarious farm employment and dampen the impetus for structural change through collective food movement organizing.     

Topoiesis de los dispositivos de registro del texto literario

ABSTRACT

Never before have the layout, the text format, and support been as important as they are today. Studies reflecting on the relationship between the meaning of the literary text and its form have rapidly increased. This kind of study has focused mostly on the history of the reading process and the history of the book as well as on the possibilities of new technologies in the literary field. However, none of these approaches has reached the point of creating a comprehensive methodology for the analysis of the relationship between the message and its channel. This work is intended to propose a methodology of analysis based on some concepts such as peritexts (Genette) and visuo-graphic zone (Cárdenas).     

Modeling Breastfeeding and Weaning Practices (BWP) on the Coast of Northern Chile's Atacama Desert During the Formative Period

Stable isotope analysis of bone collagen is frequently employed as a means of studying the breastfeeding and weaning practices (BWP) of archaeological populations. Such studies are strengthened greatly through the application of statistical models that permit precise and model-bound estimates of weaning age, duration, trophic enrichment, and the isotopic characterization of supplementary foods. Here we present the result of a stable isotope (δ¹⁵N) and Bayesian computational modeling study of bone collagen from human subadults from two coastal cemetery sites located near the mouth of the River Loa in the Atacama Desert. Recent bioarchaeological and paleodemographic research on remains from these marine hunter-gatherer sites, which are contemporary with the Formative Period (1500 BC–AD 400), has found evidence for notably elevated rates of female fertility. Ultimately, we argue that the modeled BWP parameters, which indicate the early introduction of supplementary foods, support an argument of high fertility as gleaned from the bioarchaeological evidence, and that these results provide novel insights into the child-rearing practices of the coastal populations of the Atacama. Indeed, these populations would have seemed to have developed a set of BWP that carefully balanced the biological and economic production/reproduction of the community.     

Characterisation of obsidian subsource variability at El Paredón,Mexico

Portable X-ray fluorescence (pXRF) geochemical analysis on obsidian from five Formative period (1200 BCE to AC 100) sites from Tlaxcala, Mexico, has revealed that most of the material had similar values to those found in the closest obsidian source, named El Paredón, Puebla. Nevertheless, initial analyses did not resolve whether these materials came from the same caldera or from a specific obsidian deposit. Here we present a methodology that allows the identification of obsidian subsources. The results reveal that Tlaxcalan populations took advantage of a specific obsidian deposit called Tres Cabezas, Puebla, providing valuable new data to identify associated regional exchange networks.     

The Infrastructures of Internal Colonialism: State,Environment, and Race in Lerma,Mexico

This article explores the relations between infrastructures, labour, and internal colonialism in Lerma, Mexico. Drawing on archival and ethnographic research of two hydraulic projects there, the article argues that infrastructures are productive of the racial, environmental, and political relations that constitute internal colonialism both historically and contemporarily. I show how these infrastructural projects imagined and produced colonial relations between the environment, racialised workers, and the nation-state, and how these colonial logics endure today through infrastructures and the forms of racialised labour that maintain them. In doing so, this article contributes to literature that interrogates the relations between infrastructure and coloniality by focusing on how infrastructural labour makes internal colonialism enduring. The article concludes by reflecting on how the labour practices that make internal colonialism enduring also point to ways of producing infrastructures otherwise.     

Virtual Forum: Archaeology and Decolonization

In this forum, patiently achieved through months of cyber-work, participants Nayanjot Lahiri (India), Nick Shepherd (South Africa), Joe Watkins (USA) and Larry Zimmerman (USA), plus the two editors of Arqueología Suramericana, Alejandro Haber (Argentina) and Cristóbal Gnecco (Colombia), discuss the topic of archaeology and decolonization. Nayanjot Lahiri teaches archaeology in her capacity as Professor at the Department of History, University of Delhi. Her books include Finding Forgotten Cities: How the Indus Civilization was Discovered (2005) and The Archaeology of Indian Trade Routes (1992). She has edited The Decline and Fall of the Indus Civilization (2000) and an issue of World Archaeology entitled The Archaeology of Hinduism (2004). Nick Shepherd is a senior lecturer in the Center for African Studies at the University of Cape Town, where he convenes the program in public culture in Africa. He sits on the executive committee of the World Archaeological Congress, and is co-editor of the journal Archaeologies: Journal of the World Archaeological Congress.

Methods of Palaeodemography: The Case of the Iberian Oppida and Roman Cities in North‐East Spain

Ancient demography is a recurrent topic in archaeology, thanks to new methods and evidence from different surveys and excavations. However, different cultures or periods are studied on their own, without any comparison being made between them and of their population dynamics. The present paper seeks to advance the situation by defining methodologies to allow diachronic comparisons between two different periods and cultures. After setting out a methodological approach, the paper goes on to apply the same to a case study: namely the Roman conquest of north‐east Spain, comparing the demography of the ancient Iberian communities (fourth‐second centuries BCE) to the Roman colonization (first century BCE to first century CE). Roman urbanism is generally supposed to increase the population in a particular territory, but our present evidence refutes this point: a decrease in population is visible in urban or proto‐urban sites from the Iberian to Roman periods, though there is an increase in the rural densities.
