Finch Cave (Holocene of Ecuador)

Where: Galapagos, Ecuador (1.2° S, 90.4° W: paleocoordinates 1.2° S, 90.5° W)

• coordinate estimated from map

When: Holocene (0.0 - 0.0 Ma)

Environment/lithology: sinkhole; brown, yellow, silty, sandy gravel

• Near the entrance, the floor of each cave was littered with hundreds of bones, as well as pieces of wood. The sediments from the different test pits are broadly similar to each other. They are very inorganic, being derived from basalts, with some secondary minerals (gypsum, flourite, apatite, minor calcite).
