Not quite what you would want to see on your dinner-plate, the Aegirocassis was a lobster-like animal that ruled the earth of its time.
480 million years ago this arthropod (insects & crustaceans) was the biggest thing on the planet, measuring in at a whopping seven feet.
Despite the horror at the thought of a 7′ centipede swimming in the ocean; this water-bug was relatively benign and ate only plankton as evidenced by the plankton-scooping flaps found on the fossil.
Called the Mother of All Bugs by some scientists, this creature has appendages that would later evolve into the legs seen on the plethora of insect and crustacean descendants left on earth in this creature’s evolutionary wake.
