Where: Kansas (37.0° N, 96.0° W: paleocoordinates 5.9° S, 31.2° W)
• coordinate based on nearby landmark
When: Hartford Limestone Formation, Bashkirian to Bashkirian (323.2 - 298.9 Ma)
• The fossils were recovered from a channel cut into the limestone, making it younger than the limestone itself.
• group of beds-level stratigraphic resolution
Environment/lithology: marginal marine
Collection methods: surface (in situ),
• The geological information on the locality is extremely limited in the only paper (Leisman et al. 1988) that A. McGowan read. There are fuller descriptions available in other papers from the volume.
