Hill No. 2, Banana River [Rio Banano Fm] (Pliocene of Costa Rica)

Where: Costa Rica (9.6° N, 82.8° W: paleocoordinates 9.5° N, 82.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Rio Banano Formation, Piacenzian (3.6 - 2.6 Ma)

• LITHOSTRATIGRAPHY: The Rio Banano Formation sits diachronously with abrupt lithological transition on the Uscari Formation, mostly conformably and sometimes disconformably. The Rio Banano Formation passes conformably into the Quebrada Chocolate Formation in the area immediately west of Limon but throughout most of the southern Limon Basin it is unconformably overlain by the breccia and coarse grained volcaniclastics of the Suretka Formation. AGE: direct date extrapolated from Bybell (1999) and Collins et al. (1999). STRATIGRAPHIC POSITION: Collection is representative of formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; siliciclastic sediments

• No paleoenvironmental data provided.
• LITHIFICATION: Unknown. LITHOLOGY: No lithologic data provided, but assumed to be siliciclastic.

Size class: macrofossils

Reposited in the PRI

Collection methods: surface (in situ),
