The Upper Cretaceous Coon Creek Formation type locality in McNairy County, Tennessee, has long been known to be an exceptional marine invertebrate lagerstattäte that was deposited in a nearshore reentrant into the ancestral continent of Appalachia. Extensive taxonomic analysis of the macrofauna over the past 100 years includes documentation of swimming reptiles, fish, marine invertebrates, and plant material. However, documentation of the palynomorph and calcareous microfossil component at the type locality has never been done. This data set provides analysis of calcareous microfossils (benthic and planktic foraminifera, calcareous nannofossils, and ostracods) and palynomorphs (pollen, spores, algal remains, and dinoflagellates) as a means of providing detailed age control and information regarding environment of deposition.
