Stratigraphy
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: this unit was thought by Hibben to include "Sandia" (pre-Folsom) artifacts, to be entirely "Late Pleistocene," and to underlie and predate units F and H, but according to Haynes and Agogino 1986 it consists of material reworked "by rodent activity" from units F, H, and J and the "Sandia" artifacts are actually of Folsom age; there are nine 14C dates ranging from "1890+/-90" years B.P. on a "charcoal lump" to "13,700+/-400" on "large animal bone," but the youngest of six dates on bone is "8,520+/-300," so it is possible that none of the fossils are younger than Early Holocene |
