The boron isotopic composition of biogenic carbonates has been used to reconstruct seawater pH and atmospheric pCO2 on Pleistocene and Cenozoic timescales. Because of their excellent preservation and extensive fossil record throughout the Phanerozoic, brachiopods are a promising candidate for extend...
