Compsoscorpius buthiformis

Compsoscorpius buthiformis is an extinct species of scorpion that lived during the Carboniferous period. It is known entirely from fossilized remains discovered in the ancient coal measures of the United Kingdom.

This ancient arachnid lived approximately 300 to 350 million years ago during the late Paleozoic era. It existed during a time when giant insects and early terrestrial arachnids thrived in the swampy coal forests.

Paleontologists classify it as a basal arachnid that provides important clues about the evolutionary history of scorpions. Its fossilized anatomy helps researchers understand how early scorpions transitioned from aquatic environments to fully terrestrial ecosystems.

The fossilized remains of this species were primarily discovered in the coal measures of the United Kingdom. Specimens have notably been uncovered in areas like Lancashire and Yorkshire, which were once covered by dense, swampy forests.
