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. This navigation entry is not a phylogeny or a complete taxon dossier.
