This study provides an example of the potential for optically stimulated luminescence (OSL) dating to resolve chronological questions that cannot be adequately addressed using conventional radiocarbon dating alone. We have applied this method to ceramics from the Teotônio site, located beside the Teotônio waterfall on the upper Madeira River in southwestern Amazonia. This site can be understood as a persistent place, with several occupations ranging from at least 6000 BP to recent times, when...

OSL dating has advanced in the past decade with refinements in single aliquot and single grain regeneration (SAR) dating of quartz and feldspar. There is now many independent studies to evaluate the accuracy and precision of OSL dating, particularly for eolian and littoral sediments where solar resetting is often assured. This assessment will examine the potential meaning of radiocarbon ages that are > 45 ka in light of corresponding finite OSL ages for fluvial and marine sediments from the...

This is an abstract from the "Peopling the Past: Critically Evaluating Settlement and Regional Population Estimates with New Methods and Demographic Modeling" session, at the 88th annual meeting of the Society for American Archaeology. This paper presents a cautionary case study in heritage and archaeology from Melbourne, Victoria, Australia, which is undergoing a rapid transformation due to an unprecedented program of urban and regional development. Following the author’s previous work in...

This report presents a summary of the results of the Blanket Purchase Authority (BPA) 10 project sponsored by the Carlsbad Field Office (CFO) of the Bureau of Land Management and funded under the Permian Basin Programmatic Agreement. Geomorphological and geoarchaeological investigations were conducted at the Merchant site (LA 43414) and among suspected anthrosol deposits at LA 121668 and LA 171925. Analyses of soil chemistry and chronometric dates were completed.

The Carlsbad Field Office contracted Versar, Inc. to conduct remedial archaeological data recovery excavations at the Merchant site (LA 43414), a complex village settlement in southeastern New Mexico. The Merchant site was excavated by the Lea County Archaeological Society (LCAS) from 1959 to 1965, but the results of the excavations were never fully reported. The site was fundamental to the definition of the Ochoa phase, but the nature of the phase had remained poorly known since the excavations...

Recently, optically stimulated luminescence (OSL) dating of sediment has been used increasingly in the study of human occupation history in archaeology. This paper employs OSL to date the Little Springs Lava Flow, a lava flow near Mt. Trumbull, northern Arizona thought to have erupted about 1000 years ago. The accepted dates are based on cosmogenic helium dating. This lava flow covers some of the most productive agricultural land in the Mt. Trumbull area. Previous archaeological surveys revealed...

Single grain optically stimulated luminescence (SG-OSL) dating has made a major contribution to our understanding of the chronology of the Middle Stone Age of Africa. The accuracy of many of the SG-OSL chronologies has been verified by other independent dating techniques. Diepkloof Rockshelter (DRS), however, has produced disparate chronologies that have resulted in a dating controversy. Criticisms raised have been used to cast doubt on and, in some cases, dismiss the chronology for the...

Polly Schaafsma was among the first to recognize the many stylistic elements shared between Utah's Barrier Canyon rock art and the Pecos River style along the Lower Pecos Canyonlands in Texas. While the Barrier Canyon murals are markedly simpler in execution, common elements include anthropomorph shape and torso decoration, composed sets of zoomorphs, and the depiction of wild plants. During this initial study, Schaafsma (1971) defined the Barrier Canyon style based on nineteen sites located in...
