EXPLORATORY POLLEN AND PHYTOLITH ANALYSIS AT 41RG13, BIG LAKE PLAYA, WEST TEXAS

EXPLORATORY POLLEN AND PHYTOLITH ANALYSIS AT 41RG13, BIG LAKE PLAYA, WEST TEXAS:
A bison site (41RG13) buried in the lake bed of an intermittent playa (Big Lake) in Regan County, West Texas, contained bison tone, flakes, tools, and a dart point. A radiocarbon age of 7530 + 150 BP was obtained from a bison bone sample. Pollen and phytoliths were analyzed from this site to assess the utility of further analysis of pollen and/or phytoliths to reconstruct paleoenvironmental conditions in the vicinity of Big Lake Playa.

EXPLORATORY POLLEN AND PHYTOLITH ANALYSIS AT 41CV312, TEXAS:
Two pollen samples were selected for analysis from 41CV312, a site located adjacent to a small intermittent tributary to Cowhouse Creek. A radiocarbon age of 3610 + 120 BP was obtained from a buried hearth. The purpose of pollen and phytolith analyses was to identify the potential for paleoenvironmental interpretations and further pollen and phytolith analyses in conjunction with archaeological mitigation.

西得克萨斯州雷根县大湖干盐湖（playa）41RG13遗址探索性孢粉（pollen）与植硅体（phytolith）分析：
该野牛遗址（41RG13）埋藏于西得克萨斯州雷根县一处间歇干盐湖（大湖）的湖床中，出土有野牛骨骼、石片、各类工具及一枚投掷尖状器（dart point）。科研人员对遗址出土的野牛骨骼样本开展碳十四测年（radiocarbon age），获得年代结果为7530±150 BP（Before Present，即距今7530±150年）。本次对该遗址开展孢粉与植硅体分析，旨在评估后续开展孢粉和/或植硅体分析以重建大湖干盐湖周边古环境的可行性。

德克萨斯州41CV312遗址探索性孢粉与植硅体分析：
研究人员从41CV312遗址选取两份孢粉样本开展分析，该遗址毗邻考豪斯溪（Cowhouse Creek）的一条小型间歇性支流。科研人员从一处埋藏的灶址（hearth）获取的碳十四测年结果为3610±120 BP。本次孢粉与植硅体分析的目的，是明确开展古环境解读以及结合考古保护（archaeological mitigation）工作推进后续孢粉与植硅体分析的可行性。
