Extended Data Fig. 9: SOV comparison between the results using two PCA axes and ten PCA axes from ammonoids and conodonts.

From: Heterogeneous selectivity and morphological evolution of marine clades during the Permian–Triassic mass extinction

Extended Data Fig. 9

a, Sum of variance of ammonoids, first two and ten PCA axes include 89.4% and 98.0% of total variations, respectively. b, Sum of variance of conodonts, first two and ten PCA axes include 66.6% and 7.6% of total variations, respectively. Vertical bars represent 95% quantiles, calculated from 10,000 bootstrap replicates for each subset.
