Fossil pollen record in North America in 20-0 ka

This is the dataset of fossil pollen record in North America after 20 ka. The related plant biome information is constructed by the modern analog technique (Williams and Shuman 2008) and biomization method (Williams et al. 2001). The related age information is by Bacon age model (Wang et al. 2019). The fossil pollen records are collected from Neotoma (Williams et al. 2018).本数据集收录了北美地区距今20 ka以来的化石孢粉记录。其中相关的植物生物群区信息，通过现代类比技术（modern analog technique）与生物群区化方法（biomization method）构建完成（Williams与Shuman，2008；Williams等，2001）。相关年代信息基于Bacon年代模型（Bacon age model）得到（Wang等，2019）。本次收录的化石孢粉记录均来自Neotoma数据库（Neotoma）（Williams等，2018）。
