UCMP A-9002, Punta China (Pleistocene of Mexico)
Where: Mexico (31.5° N, 116.6° W: paleocoordinates 31.5° N, 116.6° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Late/Upper Pleistocene (0.1 - 0.0 Ma)
• Fossils from basal 1-6-foot stratum, at about 25 feet above sea level.
• group of beds-level stratigraphic resolution
Environment/lithology: coastal; unlithified, shelly/skeletal, sandy gravel
• Rock type: reddish brown weathering, sandy gravel; ranging in size from very fine sand to boulders 6 feet in diameter; average particle size, granules. Gravel largely unconsolidated, but
•locally cemented to form a coquina of coarse, poorly sorted sand and fossils.
Size class: macrofossils
