New species of prehistoric scorpion may have been early land explorer
(PHYSorg.com Archaeology & Fossils)

A new species of prehistoric scorpion from the early Siluarian period (approximately 437.5 to 436.5 million years ago) is described in a study in Scientific Reports. The findings suggest that Parioscorpio venator is the oldest-known scorpion reported to date and may have been capable of leaving its marine habitat and venturing onto land, a behaviour similar to that of present-day horseshoe crabs.
