These phylogenetic spindle diagrams were plotted using my R package paleoDiv (https://doi.org/10.32614/CRAN.package.paleoDiv), with some occasional light edits in Inkscape, and are based on occurrence and taxonomic data from the paleobiology database. Keep in mind that these datasets are largely unedited (except for very glaring inaccuracies), and reflect a biased and incomplete fossil (and database) record, so take care to interpret them accordingly. Feel free to make use of these charts in your presentations or lectures, or to install paleoDiv yourself and give it a try! If you need any of these diagrams in a different format or have other questions or suggestions, feel free to contact me.
