Numerous spore-like bodies have been observed in the Cedar Valley formation of Late Devonian age during routine microscopic studies of cuttings from wells in East Central Iowa. The distribution of wells in which these individuals have been observed is shown on Plate 1. They occur above the basal sandy limestones of the Solon member in a zone approximately ten feet in thickness. Recently these spore-like bodies have been studied and the zone of occurrence correlated in an attempt to determine their value as a stratigraphic marker in sub-surface correlations. This paper should be regarded as an introduction to further study.
