Anomalocaridid
“Giant” predatory worm half a billion years old unearthed in Greenland
“We have previously known that primitive arthropods were the dominant predators during the Cambrian, such as the bizarre-looking anomalocaridids”

It was big. It was weird. And this monster from the primordial seas was also a trend-setter.
Scientists on March 11 announced the discovery in southeastern Morocco of beautifully preserved fossils of a huge arthropod - the group that includes crabs, scorpions, insects, spiders, centipedes and more - that lived 480 million years ago.
