Changes in Shannon-Wiener diversity index in Mt. Slatnik (a) and Mt. Kobla (b) sections. Numbers on horizontal axis indicate meters in Figs. 6 and 8. The dashed vertical line separates samples from the Slatnik Formation (left) from samples from the Krikov Formation (right) and roughly coincides with the Triassic-Jurassic boundary. The ragged appearance of the diversity line is due to differences in granulation, as the influence of lithology could not be totally reduced
