127   2014-04-17 05:56:03.101+00 Age determined by comparison of pollen flora with reference data. A number of standard regional pollen zones have been determined through the compilation and zonation of multiple pollen profiles.

129   2014-04-17 05:56:03.101+00 Age determined to an archaeological period defined in 14C years. This is a bulk method for numerous techniques for assigning a deposit to a particular cultural period, where the period boundaries have been defined by radiocarbon dating. More specific method details should preferably be given as to how the date has been derived, but may not be available. ArchPerC14 19 Archaeological period C14 years 19 7

137   2014-04-17 05:56:03.101+00 Dating by artefact typology with calendar date. The form, design and material of an artefact may allow it to be placed in the context of a known sequence of artefact characteristics (a typological sequence). This allows it to be dated through the assumption that the typologies are correctly and independently dated. There is a slight danger or circular reasoning is the constraints of independent dating are not rigourously enforced, and a tendency for typologies to persist even if evidence suggests that there may be problems.

140   2014-04-17 05:56:03.101+00 A sequence of radiocarbon dates may be compared with variation in the C14 calibration curve, and dates nudged so that they align with the curve. The method requires a sequence to be tightly dated and may be especially useful around flatter parts of the calibration curve. User discretion is required. Wiggle 20 Wiggle matching of 14C dates 19 8
141   2014-04-17 05:56:03.101+00 Dating method which relies on the predictable growth pattern of some lichen species. Some lichens (e.g. Rhizocarpon geographicum) exhibit colonisation, linear growth and non-linear phases of growth. By calibrating sizes against surfaces of known age (e.g. buildings, grave stones) it is possible to guage the age of exposure of a surface through the sizes of the lichens growing on it. A number of variations exist in terms of how to measure. The method has been applied to historical and archaeological remains as well as to geological features such as erosion surfaces and raised beaches. Lichen 20 Lichenometry 19 8

152   2014-04-17 05:56:03.101+00 Age determination based on the post-mortem decay (or racemization/epimerization) of amino acids in fossils. The method has primarily been used to date shells, and less sucessfully on bone, teeth and wood under some conditions. AAR 3 Amino Acid Racemization 19 15
153   2014-04-17 05:56:03.101+00 Age determination by radiocarbon on humic substances extracted by pretreatment of sediments (e.g. peat, colluvium). A number of method variations are applied, aimed at dating different fractions of the sample (as opposed to the bulk dating of organic matter), including: humic acid fraction (alkali soluble) and humin fraction (alkali insoluble). Modern dates are generally determined through AMS, but older dates may have been aquired through standard counting. C14 Humous 3 C14 dating of humic substances in sediment 19 7
