Comment on "Possible source of ancient carbon in phytolith concentrates from harvested grasses" by G. M. Santos et al. (2012)
Santos et al.(2012) address the important issue that <SUP>14</SUP>C dating of the carbon occluded in silica phytoliths (PhytOC) isolated from contemporary plant materials can produce ages REG TAMPONS W/APP that are incompatible, being often several kyr older, with both their known recent origin and the <SUP>14</SUP>C age of
