资源简介：
The soil contained in inverted shells was examined for pollen, since this
location would provide evidence of pollen associated with midden use and
formation, rather than later percolation through the sediments. In addition,
tarring pebbles were washed to identify pollen recovered.
研究人员对倒置贝壳（inverted shells）内部留存的土壤开展花粉检测，因该位点可提供与贝丘（midden）使用及形成过程相关的花粉证据，而非沉积物（sediments）经后期渗滤（percolation）所带入的花粉。此外，研究人员对涂有焦油的砾石进行清洗，以识别其中回收得到的花粉。
