Burica Point, Burica Peninsula [Burica Sandstone] (Pliocene of Costa Rica)

Where: Costa Rica (8.0° N, 82.9° W: paleocoordinates 7.9° N, 82.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Burica Sandstone Formation, Early/Lower Pliocene (5.3 - 3.6 Ma)

• LITHOSTRATIGRAPHY: From Burica Sandstone Formation (Olsson 1942), which underlies the Charco Azul Fm (Pliocene) and unconformably overlies basement. AGE: Eary Pliocene as it is overlain by younger Pliocene units and shows some dissimilarity to regional Miocene faunas.

• bed-level stratigraphic resolution

Environment/lithology: marine; poorly lithified, pebbly, sandy conglomerate

• ENVIRONMENT: No environmental data reported though text mentions several shallow water forms. The presence of Calyptogena, Solemya, Thyasira could point to vent type fauna.
• SPECIFIC LITHOLOGY: Soft tuffaceous shale. LITHIFICATION: Poorly-lithified, base on figured specimens.

Size class: macrofossils

Reposited in the PRI

Collection methods: quarrying,

• COLLECTORS: Presumably collected by A.A. Olsson or Mr Terry. REPOSITORIES: Collections reposited at PRI.
