Fig. 2.

Distribution of marine teleost survivors (open triangles, blue envelope) and victims (filled circles, red envelope) of the end-Cretaceous extinction, showing the effect of excluding some dataset partitions (vertical axis) and different models of character evolution used to estimate trait values for inferred boundary-crossing lineages (horizontal axis). The distribution of survivors and victims is significantly different regardless of these permutations (significance indicated in upper right-hand corner of the plots). The number of genera is indicated in the lower left-hand corner of the plots; the figure in parentheses indicates the number of victims. Dataset partitions are as follows: Nardò: taxa making their last appearance in the imprecisely dated Nardò fossil assemblage; Recent, boundary crossing lineages inferred on the basis of extant taxa alone (i.e., no Cenozoic body fossil record).
