Where: Lincoln County, Nevada (38.1° N, 114.6° W: paleocoordinates 9.9° S, 51.9° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Joana Limestone Member (White Pine Shale Formation), Kinderhookian to Kinderhookian (358.9 - 343.0 Ma)
• Name of the formation is in debate (according to this paper). Either Joana Limestone is a member of the White Pine Shale or it is a formation of its own. Eastern NV stratigraphic subcommittee recommended the former.
• group of beds-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified, shelly/skeletal, gray limestone
