Anou-Melloum, near Gao (niveau éocène) (Paleocene to of Mali)

Also known as Anou Mellem, Anou Mellene

Where: Mali (17.4° N, 0.4° E: paleocoordinates 9.7° N, 4.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Teberemt Formation, Selandian to Selandian (61.6 - 56.0 Ma)

• STRATIGRAPHIC RELATIONS: From unknown lithostratigraphic unit. AGE: Eocene, according to Lemoine, and also Miller (1951). However, age is very likely Paleocene, and possibly Thanetian, and presumably comes from the Teberemt Formation of O'Leary et al. (2019), because it is the highly fossiliferous unit and as the early Eocene Tamaguélelt Formation is a phosphorite that has almost no shelly fossils. STRATIGRAPHIC POSITION: From unknown position in local section.

• bed-level stratigraphic resolution

Environment/lithology: lithified limestone

• ENVIRONMENT: Shallow marine carbonate setting.
• SPECIFIC LITHOLOGY: Limestone. LITHIFICATION: Lithified, on the basis of figured specimens.

Size class: macrofossils

Preservation: mold/impression

Collected by Mission Arnaud-Cortier in 1907; reposited in the MNHN

Collection methods: surface (in situ),

• COLLECTOR: Lieutenant Cortier and Capitaine Arnaud. REPOSITORY: Not stated in text, but at MNHN.
