Where: Mexico (29.0° N, 118.2° W: paleocoordinates 29.0° N, 118.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Late/Upper Pleistocene (0.1 - 0.0 Ma)
• The formation is interpreted as of Sangamon Interglacial age because two samples have been isotope dated at about 110,000 and 130,000 yr. BP, and because of the large representation of tropical marine invertebrates: a tropical coral of the genus Pocillopora comprises the bulk of the fossils and there are several tropical gastropods that are likewise now confined to the warm waters from near the mouth of the Gulf of California to northern Peru.
• bed-level stratigraphic resolution
Environment/lithology: peritidal; lithified limestone
Size class: macrofossils
