Where: Gotland, Sweden (56.9° N, 18.1° E: paleocoordinates 17.7° S, 2.3° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Pseudomonoclimacis latilobus graptolite zone, Burgsvik Sandstone Formation, Ludlow (427.4 - 423.0 Ma)

• Upper Ludlow

• member-level stratigraphic resolution

Environment/lithology: shallow subtidal; shale and mudstone
