The geochronological potential of isoleucine epimerisation in cassowary and megapode eggshells from archaeological sites

Clarke, Simon J; Miller, Gifford Hubbs; Murray-Wallace, Colin V; David, Bruno; Pasveer, Juliette


Our research demonstrates that the extent of isoleucine epimerisation (A/I) in fragments of avian eggshells provides geochronological information in archaeological contexts. In the archaeological sequence of Hay Cave, northern Queensland, Australia, there is an excellent correspondence between the A/I values of Australian brush-turkey (Alectura lathami) eggshells (n = 99) and independent geochronological control (n = 16 radiocarbon ages including 4 on eggshell calcite). The A/I values identify...[Show more]
