Abstract

A strong relationship between the oxygen isotope composition (expressed as
δ
18
O) of
body water and relative humidity has been demonstrated for a number of mammalian
herbivores with low drinking water requirements, including kangaroos. Consequently,
it has been suggested that the oxygen isotope composition of preserved mammal
remains may be used to reconstruct past relative humidity. Other physiological,
environmental and ecological factors may also influence mammalian
δ
18
O, thereby
confounding the climatic signal, yet these factors have been rigorously examined in
few taxa.
