Contact Cut, reef stage 2, back-reef (Pliocene to of Costa Rica)

Also known as Reef 3597

Where: Costa Rica (10.0° N, 83.1° W: paleocoordinates 9.8° N, 82.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Buenos Aires Member (Quebrada Chocolate Formation), Early/Lower Pliocene to Early/Lower Pliocene (5.3 - 2.6 Ma)

• 3.7-3.6 Ma, late Early-early Late Pliocene

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified limestone and siliciclastic

• stage 2: beginning of siliciclastic input, transition fringing to barrier reef, close to coast, max. water depth 20 m
• The back reef consists of small patches of coral. The patches are smaller than those in Stage 1, measured from 1 to 3 m high and 2 to 6 m wide.

Size class: macrofossils
