Assembled over decades by Barry Sutton at the I-170 road cut in St. Louis, the Lake Neosho collection documents the Altamont Formation's Lake Neosho Shale Member, a Middle Pennsylvanian deposit rich in marine and coastal life.
Catalog numbers follow museum archival standards using the format PH-LN-[page number]. Specimen records link directly to their original documentation at lakeneosho.org.

Barry Sutton built this collection over a lifetime of fieldwork at the I-170 road cut and surrounding Missouri localities. He documented each specimen carefully and maintained lakeneosho.org as a public reference. Barry transferred stewardship of both the physical collection and the website to Jon Porter, who later founded Paleoheritage to give that work a permanent home and to pursue documentation, stewardship, and advocacy for fossil sites, collections, and their histories.
Three hours of oral history interviews with Barry have been recorded and archived. The collection continues to be cataloged and expanded.
