Abstract
The carbon isotope composition is highly variable in all of the brachiopods studied. Analysis of samples from specialised regions of the secondary shell layer show a pattern of depletion in 13C relative to non-specialised secondary material. The carbon isotope variability is independent of δ18O and is repeated in most of the articulated species regardless of geographical location. This is possibly a vital effect produced by metabolic prioritisation.
