Where: Nebraska (40.0° N, 97.0° W: paleocoordinates 21.5° S, 58.6° W)

• coordinate based on political unit

• basin-level geographic resolution

When: Scotch Grove Formation, Wenlock (433.4 - 427.4 Ma)

• "All occurrences...are of probable early Wenlockian age, although a latest Llandoverian (late Telychian) age cannot be ruled out for the earliest occurrences, as they co-occur with amorphognathoides-Zone conodonts. Type locality is middle part of Scotch Grove Formation, Buck Creek Quarry. Also known in the Welton Member.

• formation-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; dolomitic, shelly/skeletal lime mudstone and dolomitic, shelly/skeletal wackestone
