Life reconstruction of Praearcturus gigas © Franz Anthony High Res
Summary
• Fossil fragments suggest Praearcturus gigas represents the largest scorpion ever discovered, perhaps one metre in length
• Specimens held in the Natural History Museum collection since the 1870s have been reinterpreted using modern techniques
• Giant scorpion lived tens of millions of years before other famous “giant” arthropods, reshaping ideas about how and why early arthropods grew so large
