Where: Sweden (61.0° N, 15.0° E: paleocoordinates 31.6° S, 7.4° W)

• local area-level geographic resolution

When: Dalby Formation, Costonian to Costonian (458.4 - 457.2 Ma)

• Probably the Dalby Fm., but not entirely sure. Same lithology of same age, in same general area.

• formation-level stratigraphic resolution

• Grey, nodular soarse to fine-grained calcarenite with intermittent oolites and clay
