A Sea-Scorpion called Megalograptus, one of the most grotesque of predators.
— Allen about Megalograptus
in Eye of the Beast

Megalograptus (name meaning "Big Writing") is a genus of eurypterid that originated during the Late Ordovician Era in what is now North America. Measuring 2 meters long, these sea scorpions are famous for being among the first creatures to come onto dry land.

In the Series 1 episode, "Eye of the Beast", nearly a dozen Megalograptus were brought to the park. They reside on the Primeval Aquarium exhibit.


Era & DiscoveryEdit

Megalograptus lived during the Ordovician between 460 –  443 million years ago. They were one of the top predators of their time. However, they were prey animals for Cameroceras.

Physical AttributesEdit

Measured 6 feet (2 m) long, Megalograptus belonged to a group of marine arthropods called eurypterids. These animals were marine scorpions which lacked the stinger on the tip of their tail and were replaced with a fluke. It had long arms with lots of spines ranging in size running down the length of them.

Behavior & TraitsEdit

When it comes to breeding, Megalograptus moved in the shallows, moved towards the shore and produce a mass spawning. Whenever there is a full moon out and the highest tide comes in, they lay their eggs in the sand, the eggs will be protected and when the next high tide would come, probably in about a month or so, the young larvae will hatch and be taken back out to sea.

Some of the Megalograptus would stay around on the shores and wait until the eggs would hatch. Some fossils have been found that baby sea scorpions have been found inside the stomach of the big ones. That’s what they do; they wait around the shore and feed on the babies as they hatch on the next high tide.
