The networks are based on taxon subsets of the matrix compiled by

Figures 1 and 2 show time-slice-wise networks, each network includes only species of one geological period. Permian, Triassic and Jurassic (Fig. 1); Cretaceous, Paleogene+Neogene, and modern-day (Fig. 2). Species names are abbreviated/contracted by three-letter codes. Higher taxa and according colouring of species (dot) follow Bomfleur et al. (2017). Refer to this study for basic inference methodology and information on the data.
Figures 3 to 6 show connected neighbour-nets, each including the species of two subsequent time-slices (older at bottom): Permian + Triassic and Triassic + Jurassic (Fig. 3); Triassic + Jurassic and Jurassic + Cretaceous (Fig. 4); Cretaceous + Paleogene and Paleogene + Neogene (Fig. 5); Paleogene + Neogene and Neogene + modern-day (Fig. 6). For the motivation to stack networks see

The XLSX-file includes the basic distance matrix including the full taxon names; cells are coloured as heat-map: green = low pairwise morphological distances; red = high pairwise morphological distances.
All primary data files including the NEXUS-file used to generate the distance matrices for network inference can be found in the ZIP-archive. The *.DIST files are Split-NEXUS-formatted files and are partly colour-coded using in-built functions of SplitsTree. See Readme.txt for archive content and contact details.
