Melawi Group (Eocene of Indonesia)

Where: Indonesia (0.1° N, 111.5° E: paleocoordinates 3.3° N, 116.8° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Melawi Group, Late/Upper Eocene (37.2 - 33.9 Ma)

• STRATIGRAPHIC RELATIONS: From the Melawi Group, for which lithostratigraphic contacts are not reported. AGE: Late Eocene, on the basis of microfossil biostratigraphy and macrofaunal similarity with other regional units. STRATIGRAPHIC POSITION: From unknown position within group.

• group-level stratigraphic resolution

Environment/lithology: marginal marine; shale

• ENVIRONMENT: Brackish and rather shallow siliciclastic marine.
• SPECIFIC LITHOLOGY: Presumably shale, though not implicitly stated. LITHIFICATION: Unknown.

Size class: macrofossils
