Wheeley et al. Supplementary material					

Table 1. Full results of oxygen isotope analyses of conodonts measured using the Cameca 1270 including University of Birmingham Lapworth Museum of Geology accession numbers referred to in the main text and figure captions. For each specimen, age, provenance, taxonomic assignments, conodont Colour Alteration Index (CAI), tissue analysed, and V-SMOW is shown along with the sample mean, standard deviation, standard error of the mean, range, and in the last column results of Shapiro-Wilk tests undertaken in PAST (Hammer et al. 2001)  as a guide to whether or not the V-SMOW values come from a normally distributed sample of oxygen isotope values. The null hypothesis for this test is that the data came from normally distributed dataset. If the P-value is less than 0.05, then the null hypothesis is rejected. If the P-value is greater than 0.05, then the null hypothesis has not been rejected. Double horizontal lines define specimens whereas single horizontal lines demarcate sets of analyses within elements.
