Short summary
This paper studies the chemistry of modern marine shells called brachiopods. We investigate the relationship of the chemistry of these shells with sea temperatures to test and develop tools for estimating sea temperatures in the distant past. Our results confirm that two of the investigated chemical markers could be useful thermometers despite some second-order variability independent of temperature. The other chemical markers investigated, however, should not be used as a thermometer.
