Pulmonoscorpius means "lung scorpion" is an extinct genus of scorpion that lived in Scotland during Early Carboniferous period. It was one of the largest scorpion to have ever lived, with the largest known individual having an estimated length exceeding 70 cm (28 inches). Pulmonoscorpius retains several general arthropod features which are absent in modern scorpions, such as large lateral eyes and a lack of adaptations for a burrowing lifestyle.It was likely an active diurnal predator, and the presence of book lungs indicate that it was fully terrestrial. We don't know what's it diet, but it's probably that it preyed on smaller arthropods and small tetrapods.
