Garoowe [Karkar Formation] (Eocene of Somalia)

Where: Somalia (8.4° N, 48.5° E: paleocoordinates 4.0° N, 42.3° E)

• coordinate stated in text

• local area-level geographic resolution

When: Karkar Formation, Late/Upper Eocene (37.2 - 33.9 Ma)

• STRATIGRAPHIC RELATIONS: Unknown lithostratigraphic relationships. AGE: Middle to Late Eocene on the basis of macrofossil biostratigraphy, but presumably from the Late Eocene part of the formation. STRATIGRAPHIC POSITION: Presumably a checklist for the entire formation.

• formation-level stratigraphic resolution

Environment/lithology: open shallow subtidal; limestone and marl

• ENVIRONMENT: Nearshore or just offshore environment, tropical conditions. Open shallow subtidal carbonate setting is inferred.
• SPECIFIC LITHOLOGY: Limestone is predominant, but also marls and shales rich in fossils. LITHIFICATION: Unknown.

Size class: macrofossils

Collection methods: COLLECTORS: Based on survey of literature. REPOSITORY: Not stated in text.
