Where: Ecuador (0.4° S, 90.3° W: paleocoordinates 0.7° S, 92.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Pliocene (5.3 - 2.6 Ma)
• STRATIGRAPHIC RELATIONS: From unnamed lithostratigraphic unit, for which stratigraphic relationships are not discussed. AGE: Pliocene. STRATIGRAPHIC POSITION: The fossil-bearing bed on the south end of the bay on the west side of the island is about 3 meters (10 feet) thick and dips about 5° or 6° south. Large angular blocks of lava in the lower portion of the bed offer evidence of deposition very near the shore.
• bed-level stratigraphic resolution
Environment/lithology: marine; poorly lithified siliciclastic sediments
Size class: macrofossils
Collected by Slevin in 1927; reposited in the CAS
Collection methods: bulk, surface (in situ), sieve,
• COLLECTOR: J.R. Slevin, 1927. REPOSITORY: CAS.
