Divaca (Paleocene of Slovenia)

Where: Slovenia, Slovenia (45.7° N, 14.0° E: paleocoordinates 35.9° N, 12.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Upper Member (Trstelj Formation), Thanetian (59.2 - 56.0 Ma)

• Correspond to the upper part of the Trstelj beds (Operculina Lms.) of Pavlovec (1963) and to the upper part of the Miliolid Limestone of Stache (1889). Based on associated larger foraminifera the age of this collection correspond to SBZ 4 (Late Thanetian)

• member-level stratigraphic resolution

Environment/lithology: slope or ramp reef; lithified, lenticular, white reef rocks

• Deposition in the distal part of the mid-ramp setting affected by storms and currents, and likely periodically affected by increase of turbidity and nutrient levels
• Microbiliate-coral mound with alternation at cemtimetric scale of corals and microbial crusts to form a sort of framework.

Size class: macrofossils

Preservation: recrystallized, original aragonite, replaced with calcite

Collection methods: bulk, peel or thin section,
