Also known as P-105

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

Size class: macrofossils

Reposited in the CAS, LACM, PRI, USNM

Collection methods: quarrying,

• Collections reposited in the CAS, Los Angelese County Museum, PRI, USNM, and Tulane University
