MACROFLORAL ANALYSIS OF FEATURE FILL, AND IDENTIFICATION AND AMS RADIOCARBON DATING OF CHARCOAL FROM THE SIDE ARM SITE (02-229), BREWSTER COUNTY, TEXAS

Fill from a burned rock feature at the Side Arm Site (02-229) was floated to recover
macrofloral remains. This site is located in Brewster County, Texas. Charcoal samples
from two burned rock features were submitted for identification and AMS radiocarbon dating.
Macrofloral analysis, including charcoal identification, will be used to provide information
concerning plant resources utilized by the site occupations. AMS radiocarbon dating will
provide a temporal context for the site.

侧臂遗址（Side Arm Site，编号02-229）一处烧石遗迹（burned rock feature）的填积物经浮选处理，以回收大植物遗存（macrofloral remains）。该遗址坐落于美国得克萨斯州布鲁斯特县（Brewster County）。研究人员从两处烧石遗迹采集炭样并送检，以进行种属鉴定及加速器质谱仪放射性碳定年（AMS radiocarbon dating）。包含炭样鉴定在内的大植物遗存分析（macrofloral analysis），将用于揭示该遗址居留人群所利用的植物资源相关信息。加速器质谱仪放射性碳定年将为该遗址提供年代学背景。
