This list is composed of awards administered under the R.E. Taylor student poster prize competition, usually (but not always) held at the Society for American Archaeology annual meeting and/or the International Symposium on Archaeometry. Please note that this list does not include the many SAS-sponsored awards administered by partner conferences; only competitions managed and judged by SAS are included here.

Yun Zhang (University of Oxford): "The Archaeological and Scientific Analysis of Chinese cobalt-blue-decoration ceramics from the 7th to 13th century CE"
This paper reviews studies of Tang (618-907 CE) and Song (960-1279 CE) blue-and-white porcelains, both archaeologically and scientifically, based on published data, and compares blue-and-white with sancai which represents the earliest use of cobalt pigment in Chinese ceramics. Thirty-nine Tang blue-and-white wares and seven Song wares have been excavated from city sites, kilns, a tomb, a shipwreck, and temples. These findings identify Tang blue-and-white as export ware related to the Maritime Silk Road or suggest it was produced for foreigners in China for daily use or personal collection. Also, the results reflected the connection with Buddhist culture. All Tang and Song blue-and-white are vessels and the motifs on them are plants, insects, child, geometric and combination patterns. Palmette and lozenge motifs show the influence of Middle Eastern taste. Additionally, we re-analyse and discuss the previous scientific evidence of Tang and Song blue-and-white, including body, glaze, and cobalt pigment to reveal the origin of materials and technology of Tang blue-and-white porcelain. The raw pigment of Tang blue-and-white was possibly inherited from sancai, probably from the Middle East, and the biscuit body and high-fired clear lime glaze were provided by white porcelain. And Song blue-and-white may utilise native cobalt ore, which possibly was from Zhejiang.

Eunice Villasenor Iribe (Arizona State University): "A Statistical Comparison of the Physical Characteristics of Terracing in the Basin of Mexico"
The Basin of Mexico is a culturally and environmentally dynamic region that has been occupied for thousands of years. The region is semi-arid in climate, which has made large scale habitation difficult without modifications of the landscape. One such type of modification that has been utilized by a variety of ancient groups is agricultural terracing. Previous studies of terracing in the Americas have found that terraces often occur within a limited range of topographic conditions. This range may indicate where terracing was viewed as being the most productive. Understanding how terracing was applied at a variety of the archaeological sites in the Basin of Mexico provides insight into the planning of agricultural production in the region. This analysis is based on the mapping of terrace features among 4 separate hilltops: Cerro Ahumada, Cerro Gordo, Cerro San Lucas, and Cerro Chiconautla. The terrace features for each site were then analyzed to determine if they occurred within a specific range for slope, vegetation cover (NDVI), soil moisture (NDMI), and aspect. The results support the idea that there does appear to be a general topographic range for agricultural terraces which may correspond to a limit for productivity.

Benjamin D. Smith (University of Florida): "Imports and Outcrops: Characterizing the Baantu Obsidian Quarry, Wolaita, Ethiopia, Using Portable X-Ray Fluorescence"
Stone quarries are crucial nodes in the complex networks constituting hunter-gatherer economies. However, our knowledge of how these networks evolved in the late Pleistocene Horn of Africa is hindered by a paucity of well-studied quarries. The Baantu obsidian quarry in SW Ethiopia was exploited by the Pleistocene occupants of nearby Mochena Borago Rockshelter for over 50 thousand years and continues to be the preferred source of toolstone for Wolaita hideworkers today. It is composed of both in-situ outcrops and massive quantities of surface artifacts ranging from Early to Later Stone Age types. While the outcrops have clearly been mined, these surface materials may also have been a valuable source of toolstone. Distinguishing between the two geochemically is crucial when tracing the movement of this obsidian across the landscape. This poster describes the first geochemical characterization of these outcrops and some surface materials, using portable X-Ray Fluorescence (Bruker IIIeV Tracer +). Across most elements, simple cluster analysis reveals a distinct outcrop signature and a mix of imported and locally made obsidian artifacts on the surface. We must therefore consider both outcrop mining and recycling of non-local materials as important aspects of the behavioral variability associated with Pleistocene stone economies, particularly at sites like Mochena Borago with deep and prolonged occupational histories that span multiple periods of climatic and likely social change.
