| Summary: | See Fig 7 for the location of these windows within the records. (a) (e) (i) (m) (q), detail of the coiling ratio record, error bars represent 95% confidence intervals. Asterisks indicate the sample chosen for more detailed study. (b) (f) (j) (n) (r), absolute accumulation rate of dextral (red) and sinistral (blue) added cumulatively to give total Pulleniatina . (c) (g) (k) (o) (s), stable isotope analyses of individual Pulleniatina shells from the sample level highlighted with asterisks. Blue = sinistral, red = dextral. Highlight boxes indicate whether the stable isotope ratios of sinistral specimens are significantly more positive (+) or negative (-) than dextral specimens at 95% confidence, highlighted in green, or if there is no significant difference (x), highlighted in yellow. (d) (h) (l) (p) (t), size distributions of sinistral (blue) and dextral (red) Pulleniatina specimens. Bar = mean, box = standard deviation, whiskers = total range. Highlight boxes indicate whether sinistral specimens are significantly larger (+) or smaller (-) than dextral specimens at 95% confidence or if there is no significant difference (x).
