Fig. 2 in Middle Miocene conoidean gastropods from western Ukraine (Paratethys): Integrative taxonomy, palaeoclimatogical and palaeobiogeographical implications

Fig. 2. Comparison of 10 assessed variables between allied taxa: sample mean, horizontal line; 95% confidence intervals (CI), shaded boxes; ranges, open boxes (specimen measurements in SOM 2). The mean sample is a point estimate of the population mean (μ), and the corresponding CI is a range of plausible values for μ. If two parameters have non-overlapping CI, they are considered to be significantly different. The 95% confidence interval is based on the standard error for the estimate of the mean and the t distribution. For extremely small samples (n <5; SOM 2) only ranges are reported (see Beninger et al. 2012). Abbreviations: M., Mangelia; B., Bela; P., Pyrgocythara; H., Haedropleura.
