    • The geological durations of species in our analysis, from the base of the stage of first appearance to the top of the stage of last appearance, vary from 2.0 to 32 My, with a median [±1 SE (SOM, of 8.7 ± 0.4 My 27, Median durations are 9.3 ± 0.4 My for the shaded species in Fig. 1, and 8.3 ± 0.4 for the remaining species. The median time taken to attain peak occupancy, measured from the base of the stage of first appearance to the midpoint of the peak stage, is 4.0 ± 0.5 My for all species, 3.9 ± 0.5 My for the shaded species in Fig. 1, and 4.6 ± 0.6 My for the remaining species. The median time between the midpoint of the peak stage and the top of the stage of last appearance is 4.5 ± 0.3 My for all species, 4.6 ± 0.4 My for the shaded species in Fig. 1, and 4.5 ± 0.6 My for the remaining species. The subsets of species are statistically indistinguishable from each other in median duration, time from first appear
    • The geological durations of species in our analysis, from the base of the stage of first appearance to the top of the stage of last appearance, vary from 2.0 to 32 My, with a median [±1 SE (SOM)] of 8.7 ± 0.4 My (27). Median durations are 9.3 ± 0.4 My for the shaded species in Fig. 1, and 8.3 ± 0.4 for the remaining species. The median time taken to attain peak occupancy, measured from the base of the stage of first appearance to the midpoint of the peak stage, is 4.0 ± 0.5 My for all species, 3.9 ± 0.5 My for the shaded species in Fig. 1, and 4.6 ± 0.6 My for the remaining species. The median time between the midpoint of the peak stage and the top of the stage of last appearance is 4.5 ± 0.3 My for all species, 4.6 ± 0.4 My for the shaded species in Fig. 1, and 4.5 ± 0.6 My for the remaining species. The subsets of species are statistically indistinguishable from each other in median duration, time from first appearance to peak occupancy, and time from peak occupancy to last appearance (SOM). Nor are there any significant differences between the median time from first appearance to peak and the median time from peak to last appearance (SOM).
