  • The survival of amino acids continues to be explored, particularly in investigations of amino acid racemization (AAR) dating and bulk amino acid analysis to investigate the biological origin of artifacts and objects.

    “The survival of amino acids continues to be explored to the present day, in particular, in investigations of amino acid racemization (AAR) dating, as well as bulk amino acid analysis to investigate the biological origin of particular artifacts and objects”

    From Ancient protein analysis in archaeology (2021) · cites this paper as [11]

    The Introduction describes AAR dating of archaeological marine shells, and the Chiral amino acid analysis section describes measuring their amino acids. The paper uses those measurements to assess degradation and age; it does not support the separate claim that bulk amino acid analysis is used to determine the biological origin of artifacts or objects. Page numbers were not available in our copy. (LLM, conf=0.88)

  • AAR has seen particular success in highly mineralized substrates that act as closed systems, such as mollusk and avian shell and tooth enamel, where intracrystalline amino acids should remain endogenous and predictable.

    “However, AAR has seen particular success in highly mineralized substrates that act as closed systems (26). Such substrates for analyses include mollusk and avian shell (11, 26, 27) as well as tooth enamel (13, 28), which are substrates where intracrystalline amino acids should remain endogenous and predictable.”

    From Ancient protein analysis in archaeology (2021) · cites this paper as [11]

    The Introduction and ‘Testing the closed system in Chicoreus and Strombus’ support successful AAR dating using isolated intracrystalline amino acids in some mollusk shells. The paper cautions in ‘Bleaching and leaching tests: rationale’ that not all mollusks are suitable, and it does not establish closed-system behavior for avian shell, for which this citation is also supplied. Tooth enamel is cited to other sources in the citing sentence. (LLM, conf=0.86)

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.
