Rio Engabao (Edmunds collection) (Pleistocene of Ecuador)

Where: Santa Elena, Ecuador (2.3° S, 80.8° W: paleocoordinates 2.3° S, 80.8° W)

• coordinate stated in text

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

Environment/lithology: fluvial; lithology not reported

• The sediments containing the vertebrate remains described here are of estuarine type and were probably laid down by a large stream ancestral to the modern Rio Engabao, but with considerably greater run-off than the present stream. The vertebrate localities probably were near or at the mouth of the old river, and at or very close to sea level. Conditions very similar to those postulated for the Pleistocene Rio Engabao can be seen at the present time at Palmar, about eighteen miles to the north, where a small stream reaches the coast and spreads out into a brackish water swamp with mangroves.

Size class: macrofossils
