article i nfo Few constraints exist on the major element chemistry of ancient oceans. Turritellid marine snails precipitate aragonitic shells and are abundant in the Cenozoic fossil record, and therefore may be ideal for reconstructing past seawater chemistry. Here we report strontium to calcium (Sr/Ca) ratios of modern and early Cenozoic turritellid shells that still retain an aragonitic mineralogy. By applying partition coefficients determined from modern specimens to data for Paleocene and… Expand
