Palaeontology News: the first sea scorpions

Eurypterids (sea scorpions) are a major and allegedly charismatic group of large extinct arthropods (bah! give me a nice wriggly worm any day!)... but their origins remain hidden. A new paper by Peter Van Roy and colleagues has shown that there's even more missing than we all though, because it forces their early evolution back into the Cambrian. If that's the case, then where are they all? This little investigation dives into what we know about their origins, what we don't know... and why, perhaps, we don't know it! The paper is available open access and is well worth a read: https://royalsocietypublishing.org/rs... Presenter: Joe Botting
