NMB Loc. 19122 - Punta Verde [Angostura Fm] (Miocene of Ecuador)

Also known as PPP# 3391

Where: Esmeraldas, Ecuador (1.1° N, 79.4° W: paleocoordinates 0.7° N, 77.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Angostura Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• The Angostura Formation is Late Miocene age (planktic foraminiferal zone N. 16). It is apparently the Ecuadorian equivalent of the Gatun Formation of Panama. The formation is largely barren, but in a few places there are lenses or interbeds filled with finely preserved fossils. Overlies the Viche Formation, and is overlain by the lower Onzole Formation.

• bed-level stratigraphic resolution

Environment/lithology: coastal; siliciclastic sediments

• Shallow water
• Unknown, presumably siliciclastic lithology.

Size class: macrofossils

Collected by Jun al. in 1999; reposited in the NMB
