Where: Angola (12.2° S, 13.7° E: paleocoordinates 28.8° S, 1.7° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Hysteroceras orbignyi ammonoid zone, Late/Upper Albian (105.3 - 99.6 Ma)

• STRATIGRAPHIC RELATIONS: From unknown lithostratigraphic unit. AGE: Late Albian, on the basis of ammonoid biostratigraphy; Hysteroceras orbignyi-Hysteroceras varicosum zones. STRATIGRAPHIC POSITION: From unknown position within local section.

• group of beds-level stratigraphic resolution

Environment/lithology: lithified, gray, yellow limestone

• ENVIRONMENT: Not stated in text, but presumably shallow marine carbonate.
• SPECIFIC LITHOLOGY: Light yellowish to grayish limestone of variable texture, compact patches of almost lithographic character being surrounded by argillaceous and arenaceous areas. LITHIFICATION: Lithified, on the basis of figured specimens and facies description.

Size class: macrofossils

Preservation: cast, mold/impression
