Supplementary data for: Mass extinction triggered the early radiations of jawed vertebrates and their jawless relatives (gnathostomes)

This Dryad folder supports a published analysis (Hagiwara and Sallan,
2026; Doi: 10.1126:sciadv.aeb2297) of conodont (early cyclostome
vertebrates) global genus richess and gnathostome (jawed vertebrates and
relatives) global species richness and faunal composition between the
Ordovician period (480 Million years ago, Ma) and the end-Devonian (360
Ma). It includes Data Files S1-S8, which comprises species lists and
environmental and age information for 169 gnathostome vertebrate
assemblages (faunas), matrices of species occurrences in 12 taxonomic
categories in each fauna used in multivariate and ordination analyses and
to construct histograms, all Ordovician-Devonian gnathostome species
occurrences (N=1576) used for curves of species and genus richness,
Ordovician-Silurian conodont species occurrences downloaded from the PBDB
(N=1398). It also includes all R code, output files for analyses, and
figure and table files. Please refer to the Materials and Methods of
Hagiwara and Sallan, 2026 and the Supplementary Materials for details.
These data provide a basis for examining the influence of extinction,
incumbency, and biogeography on the initial radiations of
gnathostomes.
