FIGURE 4. Analysis of morphological diversity changes through time. Black line represents mean, light grey and dark grey areas represent 50% and 95% confidence intervals, respectively. Sum of variances used as measure for morphological diversity on y-axis. Stratigraphic time bins in million years on x-axis, from left to right: Eocene, Oligocene, Miocene, Pliocene, Pleistocene including extant fauna. Ages following Cohen et al. (2023). Asterisks mark significant changes between time bins.
