Abstract

The modern soils and paleoenvironmental study sites are located in Kansas and northern Oklahoma. Given the potential that opal phytoliths and other soil microfossils offer for paleoenvironmental reconstruction, the aim of this study was to analyze the combined records of, opal phytolith assemblages, burnt grass phytoliths, micro-charcoal density, and Sporormiella spores in order to reconstruct paleovegetation, paleofires, and paleograzing conditions. Also, stable carbon isotope analysis of soil and sediment organic matter was included. These regional results yield information on vegetation change, fire history, and herbivore impacts, which is sorely needed given the paucity of regional pollen records
