Only species which pass both tests can be considered suitable for further studies to obtain reliable age information.

This amino acid geochronological technique is also applied to midden deposits at two latitudinal extremes: Northern Scotland and the Southern Red Sea.

This paper explores the potential application of a new methodology of amino acid racemization (AAR) dating of shell middens and describes a simple protocol to test the suitability of different molluscan species.

This protocol provides a preliminary test for the presence of an intracrystalline fraction of proteins (by bleaching experiments and subsequent heating at high temperature), checking the closed system behaviour of this fraction during diagenesis.

These are also preserved in sediments which accumulated as a response to global climatic pulses, during the Pleistocene and beyond.

The idea of isolating and dating individual compounds such as single amino acids, to improve dating accuracy, has been discussed in the literature since the 1960s.Well to some extent maybe but it reveals a very simplistic understanding of dating techniques and of science itself.
