ALT Figure 1: Plot of global benthic δ18O data for 0 – 5.3 Ma (Lisiecki and Raymo, 2005) with geomagnetic polarity subchrons displayed on the left y-axis and planktic foraminiferal primary biozones plotted on the right y-axis.

ALT Figure 2: A mammal phylogeny (Garland et al., 1992) plotted using the ggtree and deeptime packages. The greyscale background indicates geological stages, whereas the colored timescale indicates geological epochs.

ALT Figure 3: Crinoid morphological disparity data (Wright, 2017; Guillerme et al., 2020) plotted using the coord_trans_xy() and facet_wrap_color() functions to show the change in distribution across the end-Ordovician extinction.

ALT Figure 4: A stratigraphic column of Cretaceous lithostratigraphic units from the San Juan Basin, USA. The pattern fills indicate the primary lithologies of the units as reported by the Macrostrat API (Peters et al., 2018) via the rmacrostrat R package (Jones et al., 2024).
