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
