Where: Orange County, California (33.6° N, 117.9° W: paleocoordinates 33.6° N, 117.9° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Late/Upper Pleistocene (0.1 - 0.0 Ma)
• STRATIGRAPHIC RELATIONS: From unnamed terrace deposits that overly the Niguel Fm (Late Pleistocene) AGE: Late Pleistocene, on the basis of geochemical dating. Uranium series dating (Grant et al., 1999) of a solitary coral from a nearby correlated locality gave an age of 122,000, giving the Fletcher Jones site an approximate age range of 120-125 Ka. STRATIGRAPHIC POSITION: From terrace deposits 2-2.5 m above an unconformity with the Niguel Fm.
• bed-level stratigraphic resolution
Environment/lithology: coastal; unlithified sandstone and poorly lithified, silty mudstone
Size classes: macrofossils, mesofossils
Collection methods: bulk, sieve,
• COLLECTOR; Powell et al. REPOSITORY: Orange Co. Paleontology Collections.
