Where: Trøndelag, Norway (63.1° N, 10.0° E: paleocoordinates 31.5° S, 10.5° W)
• coordinate estimated from map
When: Didymograptus bifidus graptolite zone, Hølonda Formation, Early/Lower Llanvirn (466.0 - 463.5 Ma)

• formation-level stratigraphic resolution
Environment/lithology: marine; siltstone
•The fossiliferous rock might be termed a silty argillite."
