PRI Loc. 816, Luculo River [Quimbriz Fm] (Eocene of Angola)

Also known as Loc. S 4 of Caster (1938)

Where: Angola (6.7° S, 12.5° E: paleocoordinates 12.8° S, 5.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

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

• STRATIGRAPHIC RELATIONS: From the Quimbriz Fm, which overlies the Quinzáo Fm, and is unconformably overlain by the Cobra Fm. AGE: Eocene, based on antiquated correlation with Newton's (1922) Nigerian Eocene fauna; Lutetian based on recent biostratigraphic correlations. STRATIGRAPHIC POSITION: From unknown position within the formation.

• bed-level stratigraphic resolution

Environment/lithology: marine; poorly lithified, fine-grained, argillaceous, calcareous sandstone and poorly lithified, black, gray, green, argillaceous shale

• ENVIRONMENT: Not stated in text, but apparently shallow marine siliciclastic.
• SPECIFIC LITHOLOGY: Fine-grained, clayey, calcareous sands; soft, plastic, light greenish-gray and black clay shales. LITHIFICATION: Poorly-lithified, on the basis of figured specimens.

Size class: macrofossils
