Original description of UWGM 2162 and 2163 and the historical scorpion-terrestrialization hypothesis. Anderson et al. (2021, doi:10.1111/pala.12534) rejected the scorpion identification; this source must not independently establish Scorpiones ancestry, anatomy or range.
Wendruff et al. (2020) interpreted Parioscorpio venator specimens UWGM 2162 and UWGM 2163 as scorpions and compared medial structures with a pulmonary-cardiovascular system. This claim records that study's terrestrialization hypothesis, not established scorpion anatomy, physiology or habitat.
claim:event:parioscorpio-terrestrializationParioscorpio 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.
