What happened

A child-size scorpion that roamed the UK 400 million years ago is thought to be largest of its kind to ever exist, per a skin-crawling study in the journal Paleontology.

Why it matters

“So we can safely say it’s extremely large and there’s no other scorpion in the fossil record that has claws anywhere near that size,” declared the study’s lead author Dr.

Common ground

Richard Howard of the Natural History Museum in London, the BBC reported.
