Abstract

The significance of pollen and diatoms in post-glacial sediments from a shallow bay of Lake Okoboji, Iowa, is considered. The presence of other microfossils is noted with emphasis on those of Cretaceous origin: foraminifera, coccoliths, radiolarians, and hystrichosphaerids. Problems encountered and discussed include recognition of Chrysophyte statospores, redeposition, interpretation of data from lower levels, and reliability of radiocarbon dates applied to organic matter from aquatic vegetation.
