Bybell, L.M., Self-Trail, J.M., Weems, R.E., and Seefelt, E.L., 2021, Cenozoic Calcareous Nannofossil Occurrences from South Atlantic Coastal Plain Cores: U.S. Geological Survey data release,


In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 17 cores from the South Atlantic Coastal Plain (North Carolina, South Carolina, and Georgia) Samples have been assigned a USGS sample number and are organized by depth below the land surface. Based on their known stratigraphic position, lithology, and specific calcareous nannofossil species content, each sample, where possible, was assigned to a geologic formation, age, and standard Martini (1971) calcareous nannofossil biostratigraphic zone. Five additional reference files are provided: (1) location information for each core, well, or outcrop, (2) a list of calcareous nannofossil species found in the Gulf and Atlantic [...]

Since joining the USGS in 1975, the senior author, Laurel Bybell, has examined thousands of geologic samples for their calcareous nannofossil content that were collected from cores, wells, and outcrops from many locations, but primarily from the Gulf and Atlantic Coastal Plains. Most samples were examined to determine their geologic age. These data were of significant help to geologic mappers and hydrologists at the USGS, state geological surveys, and universities in understanding geologic formations and aquifers and their distribution through space a time. In addition, taxonomic and evolutionary studies of some calcareous nannofossil species and lineages were conducted to gain a better understanding of the fossil group and improve its utility in geologic dating.
