Where: Chatham County, North Carolina (35.6° N, 79.1° W: paleocoordinates 9.9° N, 22.9° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Cumnock Formation (Chatham Group), Norian (228.0 - 208.5 Ma)
• "These strata have been mapped as the Sanford Fm but are proximal fan facies laterally equivalent to more distal Cumnock Fm strata elsewhere in the basin" (Heckert et al. 2008)
•
•"Conewagian LVF", previously considered late Carnian in age but redated as early Norian (Sues & Fraser 2010. Triassic Life on Land)
•
•Sanford subbasin of the Richmond Basin.
•
•Considered early Norian in Heckert et al. 2012.
• bed-level stratigraphic resolution
Environment/lithology: "floodplain"; red, blue mudstone and lenticular, paleosol/pedogenic, gray, red siltstone
