Sharks have dominated headlines this summer, but according to newly published research from Yale scientists, this likely wouldn't have happened 460 million years ago.
In the latest BMC Evolutionary Biology study, the scientists describe the finding of a Pentecopterus decorahensis, which can most accurately be described as a large sea scorpion.
The terrifying creature "is the first real big predator" James Lamsdell, who led the study, said to the Associated Press. It was discovered in Iowa and is believed to have been there when the land was under the ocean.
Named after the Greek warship penteconter, the animal measured nearly six feet long and had two sets of legs making it well-equipped for hunting prey. It also had more appendages for maneuvering and bristles that may have been used for sensory purposes.
And, according to the Associated Press, the tail on this scorpion wasn't a stinger.
Not only is the discovery rare, but it also potentially revealed 10 million years of its group's history.
