A significant correlation between age estimates obtained using GLGs and AAR was found, whereas no correlation was found between GLGs and telomere length.

Asp racemization thus provides a means of dating recent faunal assemblages of molluscs and other biogenic carbonates, as well as recent terrestrial, fluvial and marine sedimentary sequences that contain molluscs.
