In the 1960s, archaeology was a newcomer to Quebec’s cultural francophone scene, and commercial archaeology made its first appearance at the end of the 1970s. Today, in a context of global chronic economic crisis, we intend to examine the effects of provincial and federal ideological and economic trends on the praxis of archaeology in Quebec. These include a progressive deregulation of the public sector by weakening the institutions through the termination of archaeological posts or/and non-replacement of retired archaeologists, and a progressive disengagement of the public sector through conditional regulation, accompanied by a lax attitude towards entrepreneurs, and stickler regulations for archaeologists. We present a series of current issues and examples in Quebec archaeology which illustrate these trends, in particular two case studies occurring in Montreal and Northern Quebec, respectively.  相似文献

This article uses Bruno Latour’s concept of Science in Action to consider the relationship between archaeology and geology. It is argued that neither the New Archaeology nor Postprocessual Archaeology provides a strong foundation for dialogue between archaeology and geology. Significant differences in temporal scale and structure pose a significant hurdle to integration of geology and archaeology. However, the practice of both disciplines is characterized by an internal tension between the use of imagination and intuition versus a reliance on data. This dynamic provides the basis for cooperation between geology and archaeology, but it must be realized that collaboration requires that geologists be seen as equal partners in inquiry rather than as specialists in service of an archaeological research agenda.  相似文献

Reappraisal of Austrosaurus mckillopi Longman, 1933 Longman, H.A., 1933. A new dinosaur from the Queensland Cretaceous. Memoirs of the Queensland Museum 10, 131144. [Google Scholar] from the Allaru Mudstone of Queensland, Australia’s first named Cretaceous sauropod dinosaur. Alcheringa 41, 543–580. ISSN 0311-5518

Austrosaurus mckillopi was the first Cretaceous sauropod reported from Australia, and the first Cretaceous dinosaur reported from Queensland (northeast Australia). This sauropod taxon was established on the basis of several fragmentary presacral vertebrae (QM F2316) derived from the uppermost Lower Cretaceous (upper Albian) Allaru Mudstone, at a locality situated 77 km west-northwest of Richmond, Queensland. Prior to its rediscovery in 2014, the type site was considered lost after failed attempts to relocate it in the 1970s. Excavations at the site in 2014 and 2015 led to the recovery of several partial dorsal ribs and fragments of presacral vertebrae, all of which clearly pertained to a single sauropod dinosaur. The discovery of new material of the type individual of Austrosaurus mckillopi, in tandem with a reassessment of the material collected in the 1930s, has facilitated the rearticulation of the specimen. The resultant vertebral series comprises six presacral vertebrae—the posteriormost cervical and five anteriormost dorsals—in association with five left dorsal ribs and one right one. The fragmentary nature of the type specimen has historically hindered assessments of the phylogenetic affinities of Austrosaurus, as has the fact that these evaluations were often based on a subset of the type material. The reappraisal of the type series of Austrosaurus presented herein, on the basis of both external morphology and internal morphology visualized through CT data, validates it as a diagnostic titanosauriform taxon, tentatively placed in Somphospondyli, and characterized by the possession of an accessory lateral pneumatic foramen on dorsal vertebra I (a feature that appears to be autapomorphic) and by the presence of a robust ventral mid-line ridge on the centra of dorsal vertebrae I and II. The interpretation of the anteriormost preserved vertebra in Austrosaurus as a posterior cervical has also prompted the re-evaluation of an isolated, partial, posterior cervical vertebra (QM F6142, the ‘Hughenden sauropod’) from the upper Albian Toolebuc Formation (which underlies the Allaru Mudstone). Although this vertebra preserves an apparent unique character of its own (a spinopostzygapophyseal lamina fossa), it is not able to be referred unequivocally to Austrosaurus and is retained as Titanosauriformes indet. Austrosaurus mckillopi is one of the oldest known sauropods from the Australian Cretaceous based on skeletal remains and potentially provides phylogenetic and/or palaeobiogeographic context for later taxa such as Wintonotitan wattsi, Diamantinasaurus matildae and Savannasaurus elliottorum.

A relationship between behavioral variability and artifactual variability is a founding principle of archaeology. However, this relationship is surprisingly not well studied empirically from an explicitly “microevolutionary” perspective. Here, we experimentally simulated artifactual variation in two populations of “artifact” manufacturers, involving only a single behavioral difference in terms of their “tradition” of manufacturing tool. We then statistically analyzed shape variation in the resultant artifacts. In many respects, patterned differences might not have been expected to emerge given the simple nature of the task, the fact that only a single behavioral variable differed in our two populations, and all participants copied the same target artifact. However, multivariate analyses identified significant differences between the two “assemblages.” These results have several implications for our understanding and theoretical conceptualization of the relationship between behavior and artifactual variability, including the analytical potency of conceiving of artifacts as the product of behavioral “recipes” comprised of individual “ingredient” behavioral properties. Indeed, quite trivial behavioral differences, in generating microevolutionarily potent variability, can thus have long-term consequences for artifactual changes measured over time and space. Moreover, measurable “cultural” differences in artifacts can emerge not necessarily only because of a strict “mental template” but as the result of subtle differences in behavioral ingredients that are socially learned at the community level.  相似文献

Over the past five decades, archaeologists have proposed a wide range of methods for the study of spatial organization within hunter-gatherer sites. Many of these methods sought to identify the spatial location of activities based on patterns of behavior observed in ethnographic contexts. While this resulted in productive observations at certain sites, many of these methods were tailored to specific situations and thus could not be applied to a wide range of sites. For example, open-air sites rarely contain preserved bone or features, such as hearths, which were central components to identifying characteristics of site structure. In addition, many of these methods often did not take into consideration the temporal dynamics of the occupation, i.e., that many sites were formed through subsequent occupations of differing duration. This paper proposes the use of two related methods that assume many assemblages are the result of more than one occupation. The methods target the distribution of lithic artifacts, the most ubiquitously preserved of archaeological materials, and accounts for the potential that the final resting place of artifacts was the result of both intentional and unintentional movement by humans and a host of biological and geological processes. The main goal of this paper is to use an understanding of how these processes influenced the formation of site structure to estimate the relative number and duration of occupations for each site in the sample. These new methods will be presented and explained through the study of seven open-air Middle Paleolithic sites in France but are applicable to a wide range of hunter-gatherer sites.  相似文献

Despite recent emphases on both environmental archaeology and practice theory in archaeology, the two are rarely combined. In this paper, we illustrate a genealogies of environmental practice approach that seeks to understand how human actions grounded in familiar repertoires make sense of environmental and political economic change. Employing archaeobotanical and zooarchaeological data, we first examine taxon-specific genealogies of practice and then compare them to one another as well as to broader climatic, political, and economic contexts of the last millennium in Banda, west central Ghana. In focusing on the interactivities between different kinds of data, we coax out the strategies used by Banda’s inhabitants to cope with fluctuating environmental and political conditions. We argue that during a several centuries long drought in the fifteenth to seventeenth centuries ad, Banda villagers took advantage of a diverse set of economic activities to cope with turbulence, but by the late nineteenth century, these opportunities had dwindled, diminishing the villagers’ practical options.  相似文献

The materialization of memory is one way in which the past becomes a powerful agent for negotiating the present. Today in Botswana, archaeological sites have become sites of memory where ancestors have been invoked for healing in response to the rapid spread of HIV/AIDS. This paper concentrates on one site, Khubu la Dint?a, where a local community practiced an ancestral healing ceremony, phekolo, as a way to restore spiritual balance. Told through a set of narratives that integrate ethnographic interviews with one of the former church elders, Russia, the article chronicles the trajectory of the church, the perceived power and active role of the ancestors in this ceremony, and the complex web of morality and practicality in which alternative narratives emerge during a time of social disruption and later fall apart. This paper complements the others in this issue by focusing on how memory, place, time, and material culture are recursively engaged: a process that includes formal and accepted to marginal and even ephemeral viewpoints and holds lessons for how we as archaeologists approach and curate the past.  相似文献

The creation of political landscapes requires the production of places made significant through acts of social remembering. The Gulf lowlands of Mexico exhibit some of the best known acts of social remembering in Mesoamerican prehistory. In this article, we engage political and practice-based frameworks for understanding the process of collective remembering in an examination of how the Olmecs and their successors inscribed their landscape with buildings, monuments, and rock art in ways that invoked the past while reframing it within the needs of their present. In particular, we explore the Olmecs’ memorialization of individuals and events in sculptures and offerings and their creation of narratives through the juxtaposition of sculptures and architecture. We then examine the creation and erasure of collective memory at the regional center of Tres Zapotes as expressed in the biographies of six monuments. We end with a comparison of “metropolitan” and hinterland carvings recorded in regional survey around Tres Zapotes. These examples situate social memory as an evolving entity molded and stretched by competing interests in an ongoing process of conflict and negotiation.  相似文献
