POLLEN AND PHYTOLITH ANALYSIS, AND CHARCOAL AND SEED IDENTIFICATION OF SAMPLES FROM THE SKULL HEARTH SITE (48CA214), WYOMING

The Skull Hearth Site (48CA214) contains Middle Plains Archaic, Late Plains Archaic, and Late Prehistoric campsites. One house pit (S2B4-F2) contained seven thermal features clustered and slightly offset from the center of the house pit that probably represent hearths and ovens. Fill from these the features was submitted and examined for pollen and phytolith evidence of economic activity. Three charcoal and two botanic samples recovered from S1B6-F1 and S1B7-F1 were submitted for identification.

骷髅灶址遗址（48CA214）留存有中部平原古风期（Middle Plains Archaic）、晚中部平原古风期（Late Plains Archaic）以及晚史前时期（Late Prehistoric）的营地遗存。编号为S2B4-F2的一处房坑内，分布有7处聚集且略偏离房坑中心的热遗迹，其功能大概率为灶址与烤炉。研究人员对上述遗迹的填土进行了采样送检，并通过花粉与植硅体分析，以获取该遗迹对应经济活动的相关证据。从S1B6-F1与S1B7-F1遗迹中采集的3份木炭样品与2份植物标本，已送检待鉴定。
