An Improved Method for Radiocarbon Dating Fossil Bones
Open accessAbstract
We demonstrate here that the use of either the acid-alkali or Longin method alone does not fully extract contaminants from bone-collagen fractions. We present our methods and results of extracting bone collagen that involve successive use of both of these methods.

The tested samples of coal, dinosaur bones, and South African diamonds have higher pMC values than the South American diamonds from Brazil used as test blanks by [10], who concluded that the bulk of 14C in their South American diamonds is endogenous.
“The data show that the tested samples of coal, dinosaur bones, and South African diamonds have higher pMC's than the South American diamonds from Brazil used as test blanks by [10], who concluded that the bulk of 14 C in their South American diamonds is endogenous.”

[1] argue that the coal and diamonds they tested contain intrinsic 14C, and that recorded low pMC values were not due to systematic instrument error or contamination.
“[1]argue that the coal and even diamonds they tested contain intrinsic 14 C, and that although recorded pMC's were low (as shown in Figure 1 and Tables 4 and 5) it was not due to systematic instrument error (as demonstrated by [10] or contamination.”

Thirteen diamond samples from Brazil yielded pMC values of 0.026 to 0.005, or 14C ages of 66,500 to 80,000 14C years BP.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
