• outcrop-level geographic resolution

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

• "The bones were encountered at a depth of eighteen feet" and there are radiocarbon dates on "organic material from the clay immediately surrounding the bones" of "17 220 +/- 1870"; "12 170 +/- 3060"; and "15 970 +/- 860"

• group of beds-level stratigraphic resolution
