Primary redescription rejects the scorpion interpretation while leaving exact arthropod placement inconclusive. The authors' character matrices, alternative coding analyses and specimen measurements are archived at https://doi.org/10.5061/dryad.rn8pk0p5w.
The Scorpiones range formerly used the Silurian Parioscorpio occurrence as its older endpoint. Anderson et al. (2021) rejected that fossil's scorpion identification, so this atlas withholds the inherited range pending independent scorpion evidence; no origin date is established here.
claim:taxon:scorpionesParioscorpio venator is documented from the Silurian Waukesha Lagerstatte in Wisconsin, including holotype UWGM 2162 and paratype UWGM 2163. Its 2021 redescription rejected the scorpion interpretation while leaving exact arthropod affinities unresolved; this occurrence does not date scorpion origins.
