Desplats Limestone Quarries (Lower) (Eocene of Senegal)

Where: Senegal (14.7° N, 17.2° W: paleocoordinates 10.8° N, 21.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Ngazobil Member (Thies Formation), Ypresian (56.0 - 47.8 Ma)

• Planktonic forams indicate upper Ypresian biozones E6 and E7 of Berggren and Pearson (2005)

Environment/lithology: coastal; marl and limestone

• interpreted as nearshore
• marls and limestone covering deeper layers of alternating biomicritic limestone and marls. Small layers of chert and grains of phosphate are frequently interfingered. Specimens preserved in a concretion.

Size class: macrofossils
