Vestre Svartøy, Lake Tyrifjorden (Ordovician of Norway)

Where: Ringerike, Norway (60.1° N, 10.2° E: paleocoordinates 29.2° S, 9.3° W)

• local area-level geographic resolution

When: Dicellograptus anceps graptolite zone, Meristella crassa Schichten Member (Bønsnes Formation), Pirgu (449.5 - 445.2 Ma)

• Updated from original source based on Ebbestad 1999.

• member-level stratigraphic resolution

Environment/lithology: limestone and calcareous shale

• Rubbly limestones with interbedded calcareous shales which have yielded the very diverse shelly faunas listed by Kiær (1897). The highest part of the formation comprises calcareous (>45cm thick) shales with scattered limestone nodules.

Size classes: macrofossils, mesofossils

Preservation: replaced with calcite
