Kongressfjellet (Daonella Shales) (Triassic of Svalbard and Jan Mayen)

Where: Svalbard and Jan Mayen (78.6° N, 15.3° E: paleocoordinates 42.5° N, 1.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tsvetkovites varius ammonoid zone, Botneheia Formation, Fassanian (242.0 - 235.0 Ma)

• Daonella shales (probably Middle nodule layer)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, concretionary, gray, carbonaceous shale

• Dark-grey weathering blue-black, in places it is intensely bituminous; it weathers into paperlike lamellae. The nodules consist of black, splintery, bituminous limestone weathering light-grey.

Size class: macrofossils

Preservation: concretion
