Binfield, P., Archer, M., Hand, S.J., Black, K.H., Myers, T.J., Gillespie, A.K. & Arena, D.A., June 2016. A new Miocene carnivorous marsupial, Barinya kutjamarpensis (Dasyuromorphia), from central Australia. Alcheringa 41, xx–xx. ISSN 0311-5518.

A new dasyuromorphian, Barinya kutjamarpensis sp. nov., is described on the basis of a partial dentary recovered from the Miocene Wipajiri Formation of northern South Australia. Although about the same size as the only other species of this genus, B. wangala from the Miocene faunal assemblages of the Riversleigh World Heritage Area, northwestern Queensland, it has significant differences in morphology including a very reduced talonid on M4 and proportionately wider molars. Based on the structural differences and the more extensive wear on its teeth, the central Australian species might have consumed harder or more abrasive prey in a more silt-rich environment than its congener, which hunted in the wet early to middle Miocene forests of Riversleigh.

Archaeological wood is usually severely degraded. The Norwegian Viking Age Oseberg find exemplifies problems arising due to past conservation treatments and the need for new types of preservatives. Phenol formaldehyde (PF) has been investigated as a consolidant for alum‐treated wood. X‐ray tomography has revealed that it is possible to obtain a porous structure inside the wood, ensuring ethical acceptability by allowing re‐treatment. In order to understand the curing mechanics, the kinetics of the initial condensation reaction were elucidated at room temperature. It was found that a second‐order reaction using both phenol and formaldehyde concentrations is the most probable mechanism.  相似文献

This paper uses rationale derived from central place foraging models to explore the factors that guide the carcass processing and transport decisions of modern hunters. Using data derived from butchering experiments, I test different economic indices that purportedly reflect the field processing and transport decisions of contemporary African Hadza hunter-gatherers. The results show that no single index predicts part processing and transport for the species examined in this analysis. Processing and transport decisions are, however, patterned in ways that are consistent with theoretical predictions. While similar processes likely guide carcass treatment and transport decisions among all hunter-gatherers, different ecological, social, and historical constraints define the range of solutions to problems involving carcass treatment. In this specific example, intertaxonomic differences in carcass size and bone properties constrain how the trade-offs between field processing and transport costs are resolved. I conclude by suggesting ways in which analysts might make use of central place foraging rationale and models to explain variation in skeletal representation and abundances across time and space.

Peyote, a psychoactive cactus native to the Chihuahuan Desert, has been preserved from excavations at only two archaeological sites: Shumla Caves in the Lower Pecos region of southwest Texas and shelter CM-79 near Cuatro Ciénegas in Coahuila, Mexico. We determined three indistinguishable radiocarbon ages of 5160 ± 45, 5200 ± 35, and 5210 ± 35 14C years BP, yielding a mean age of 5195 ± 20 14C years BP for the three specimens from Shumla Caves. For one of the Cuatro Ciénegas specimens we obtained the first direct radiocarbon date of 835 ± 35 14C years BP. This study demonstrates the use of peyote by inhabitants of the Lower Pecos region of the Chihuahuan Desert about 6000 calendar years ago, and confirms its use by inhabitants of the Cuatro Ciénegas region of the Chihuahuan Desert in Late Prehistoric times. The Shumla Caves' specimens are composed of an aggregate of ground peyote mixed with other plant material, i.e., they appear to be manufactured peyote effigies, and are definitely not intact peyote buttons.  相似文献

Harvey K 《Gender & history》2002,14(2):202-223
The claims of Thomas Laqueur for a shift from a one-sex to a two-sex model of sexual difference are incorporated into many recent histories of gender in England between 1650 and 1850. Yet the Laqueurian narrative is not supported by discussions of the substance of sexual difference in eighteenth-century erotic books. This article argues that different models of sexual difference were not mutually exclusive and did not change in linear fashion, but that the themes of sameness and difference were strategically deployed in the same period. Thus, there was an enduring synchronic diversity which undermines claims for linear transformation.  相似文献
