Also known as S. 8054
Where: Sucre, Colombia (9.7° N, 75.2° W: paleocoordinates 7.3° N, 68.4° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Late/Upper Eocene (37.2 - 33.9 Ma)
• No lithostratigraphic nomenclature for these collections. Deposits of late Eocene age, referred to as Zone C.

Size class: macrofossils
Reposited in the CAS, UCMP
Collection methods: quarrying,
• Collected by the Standard Oil Company of California. Held in repositories at both CAS and UCMP.
