Islas Borrachas, Chimana formation (Cretaceous to of Venezuela)

Where: State of Anzoátegui, Venezuela (10.3° N, 64.7° W: paleocoordinates 7.9° N, 33.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: lower Member (Chimana Formation), Late/Upper Aptian to Late/Upper Aptian (122.5 - 109.0 Ma)

• lower Chimana formation

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; limestone

• The corals are wholly hermatypic or reef-building types. They represent an assemblage indicative of quiet waters- shallow lagoons behind reefs. None of the specimens seems to occur in situ at the localities now known, and all show signs of rolling and breaking by water action and riddling by lithophagous mollusks.
• limestones gradational with the upper part of the El Cantil formation

Size class: macrofossils

Collected by Dr.Hollis Hedberg; reposited in the USNM
