       Gigantoscorpio is a genus of scorpion known to have lived in Scotland during the Carboniferous period.‭ ‬Because the genus is known only from partial remains,‭ ‬full details about its size and body proportions are currently unavailable.‭ ‬However,‭ ‬the genus has been occasionally estimated to have been as much as ninety centimetres long,‭ ‬which would make it big,‭ ‬even for the Carboniferous.‭ ‬During this period many arthropods similar to todays in form grew substantially bigger,‭ ‬with the main theory to explain this being that the atmosphere had a much higher oxygen content during the Carboniferous which allowed these kinds of animals to grow bigger.‭ ‬Many types of animal were known,‭ ‬and one genus of scorpion called Pulmonoscorpius also lived in Scotland at the same approximate time as Gigantoscorpio,‭ ‬and Pulmonoscorpius is thought to‭ ‬have grown up to‭ ‬70‭ ‬centimetres in length‭ (‬head to tip of the telson‭)‬.
