Bed 4, Landana Section (Paleocene of Angola)

Where: Angola (5.2° S, 12.1° E: paleocoordinates 14.6° S, 3.6° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Landana Formation, Selandian (61.6 - 59.2 Ma)

• Bed 4 assigned to the early Selandian on the basis of planktonic foraminifera biostratigraphy (Solé et al., 2018) and dinoflagellates (Steeman et al., 2019).

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal; lithified, pebbly, shelly/skeletal packstone

• Lower part of the section (beds 2-12) contains interbedded skeletal grainstones, packstones, and wackestones, with very little terrigenous component (Solé et al., 2018; Steeman et al., 2019). Tentatively assigned to a deep subtidal environment.
• Foraminiferal packstone containing shell fragments and quartz pebbles, according to Solé et al. (2018).

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.
