Fig. 10

Temporal evolution of species- genera- and subfamily-diversity (succession of UAZs) for all the characteristic (part of UAZ) conodonts from South China during the Smithian and Spathian interval. Calculated from the optimal solution given in Fig. 8. Note the Early Smithian and Early Spathian radiation and the late Smithian and middle/late Spathian extinction. Absolute ages from Widmann (2019) and Widmann et al., (2020)
