IDENTIFICATION AND AMS RADIOCARBON DATING OF CHARCOAL FROM THE PINTO CANYON RANCH SITE, PCR-69, WEST TEXAS

Charcoal from two hearth features at the Pinto Canyon Ranch site, PCR-69, in west Texas were submitted for identification and AMS radiocarbon dating. This site consists of an open camp and contains fire-cracked rock middens, hearths, and surficial charcoal stains. Charcoal identification will identify wood burned as fuel at this site, while AMS radiocarbon dates will provide temporal information.

采自得克萨斯州西部平托峡谷牧场遗址（Pinto Canyon Ranch Site, PCR-69）两处火塘遗迹的木炭样本，被送检以开展种属鉴定与加速器质谱（AMS）放射性碳测年。该遗址为一处露天营地，遗存包含火烧破裂岩石堆积、火塘遗迹以及地表木炭痕迹。木炭种属鉴定可明确该遗址作为燃料被燃烧的木材种类，而AMS放射性碳测年则可提供该遗址的年代学信息。
