Also known as NMB 12908, NMB 12912, NMB 13033
Where: Curacao, Netherlands Antilles (12.1° N, 68.8° W: paleocoordinates 10.8° N, 68.7° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Ceru Mainsjie Formation, Bartonian (41.3 - 38.0 Ma)
• Collection derived from several horizons within the Ceru Mainsjie Formation. Considered to be Early Eocene by Altena (1941). Foraminiferal evidence of Keyzer (in Schaub 1948) suggested a Late Eocene age. Hermes (1968) used planktonic foraminifera to indicate a upper Middle Eocene age. Molluscan biostratigraphy excludes an Early Eocene age, though definately point to the Eocene. Taxa are most similar to those of Late Eocene age from Peru. Jung suggests therefore that the age is Late Eocene or somewhat older, but later indicates that is probably late Middle Eocene age. Therefore the enterer (A. Hendy) assigns a Bartonian age.
