We have analyzed 214 fossil apatite samples from nine stratigraphic sections worldwide that cover the lower Cambrian to lower Ordovician for their strontiumisotope ratios. Of these samples, 180 from six sections that cover the Cambrian-Ordoviciantransition (<5 Ma) reveal how the extent of isotopic alteration can differ greatly according to lithology and sample type. From three limestone sections, 126 euconodont samples yield the most consistent 87Sr/86Sr ratios and are used in this article to constrain seawater 87Sr/86Sr across the Cambrian-Ordovician boundary. By contrast, protoconodonts, paraconodonts, and inarticulate brachiopods are far less likely to retain a primary 87Sr/86Sr signature and appear to be of only limited value for chemos...
