Bed 31, Landana, Kabinda (Eocene of Angola)

Where: Angola (5.2° S, 12.1° E: paleocoordinates 11.3° S, 5.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Landana Formation, Lutetian (47.8 - 41.3 Ma)

• STRATIGRAPHIC RELATIONS: From the "Landana beds". Bed 31 assigned to the Lutetian on the basis of planktonic foraminifera biostratigraphy (subtropical zone P3b; Solé et al., 2018) and dinoflagellates (Steeman et al., 2019). A Lutetian age for layers 29-32 is based on vertebrate and invertebrate records (see above) as these layers contain no foraminifers and d13C record is not sufficient. STRATIGRAPHIC POSITION: From upper part of section, at bed 30-31.

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, dolomitic, shelly/skeletal, cherty/siliceous packstone

• ENVIRONMENT: Not stated in text, but upper part of the section represents a shallowing trend (Solé et al., 2018; Steeman et al., 2019), so a shallow subtidal (i.e. above wave base) setting is tentatively assigned.
• LITHOLOGY: Dolomicrosparite with silica in the upper part, containing bryozoans, corals, echinoderms. LITHIFICATION: Lithified, on the basis of figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression

Reposited in the SUI

Collection methods: surface (in situ),

• COLLECTORS: Probably T.H. Clark and E. Vincent. REPOSITORY: State University of Iowa.
