Isotopic evidence indicates that Mesolithic people in Europe tended to be heavily reliant on aquatic foods, while Neolithic subsistence was dominated by agricultural products (Tauber 1981; Richards & Hedges 1999; Schulting & Richards 2001; see also papers in Bailey & Spikins 2008 and Price 2000, respectively).

As they grew, the corals absorbed the isotopic signature of groundwater seeping into the shallows offshore, thus recording changes in groundwater volume.
Such a marker, which would not require accelerator mass spectrometry or the administration of isotopic tracers, could provide information that cannot be gained from bone biochemical markers, and provide it more quickly than is possible with observed changes in bone mineral density (BMD).

The dating of important minerals and geologic materials depends upon accurate determinations of potassium (K) and argon (Ar) isotopic ratios, but significant interlaboratory disagreements (1 % to 2 %) exceed intra-laboratory uncertainties by an order of magnitude, hampering comparability of results.
Although it was recognized that isotopic species participate in chemical reactions at different rates, there was a prevailing notion that for elements heavier than hydrogen, the effects might be too small to accurately measure.
Isotopic models for herbivores provide additional complications because those mammals consume foods that have high variability in nitrogen concentrations.
