Gao Trench locality 2 (Paleocene to of Mali)

Also known as Mali-17; Mali 17

Where: Mali (16.7° N, 0.5° E: paleocoordinates 8.9° N, 4.4° W)

• coordinate based on nearby landmark

When: Teberemt Formation, Middle Paleocene to Middle Paleocene (61.7 - 55.8 Ma)

• Unit 3 - Middle to upper portion of the Teberemt Formation

• group of beds-level stratigraphic resolution

Environment/lithology: marine; limestone

• Upward fining, retrogradational marine sequence. Increasing water depth is interpreted based on reduction of siliciclastics and increasing purity of carbonates upward through the sequence.
• A 3 m thick chalky, micritic limestone with thin shale partings

Size class: macrofossils
