FIGURE 8 in The effects of lithification on fossil assemblage biodiversity and composition: An experimental test

FIGURE 8. Hypothetical rarefaction curves illustrating the potential effects of lithification or other diagenetic processes on the observed biodiversity of a fossil assemblage. The rarefaction curves are shown in blue for unlithified, unaltered assemblages and in red for the lithified, altered assemblages. A-C, Total species richness is the same in the pristine and altered samples. D-F, Total species richness is lower in the altered samples. A,D, Evenness is lower in the altered samples. B,E Evenness is the same. C,F, Evenness is higher in the altered samples.
