Meet Brontoscorpio. His kind may look like modern scorpions, but they're a meter long monster scorpion with gills, a superior armory to Anomalocaris, and a stinger the size of a light-bulb.
— Allen, about Brontoscorpio

Brontoscorpio (name meaning, "Thunder Scorpion") was a species of Eurypterid - a large prehistoric "sea scorpion" - that originated during the Late Silurian period. It is notable for being one of the first animals to walk onto land. While this creature hunted ancient fish and other smaller sea creatures. Larger predators in the waters in which it lived would have in turn preyed on Brontoscorpio - including Giant Orthocones, and even sea scorpions larger than Brontoscorpio, especially Pterygotus.

FactsEdit

Era & DiscoveryEdit

Brontoscorpio lived during the Silurian period from 440-417 million years ago alongside Cameroceras, Cephalaspis, and Pterygotus. As a species of sea scorpions, Brontoscorpio was one of the apex predators in the Silurian seas. Brontoscorpio was first discovered in 1972.

Physical AttributesEdit

Brontoscorpio was a large, black scorpion with large pincers that measured 1 meter long and resembled a modern scorpion except that it was far larger, had body armor stronger than Anomalocaris, possessed gills as well as primitive lungs and a bulbous tail with a stinger approximately the size of a light bulb. Its body was covered in a hard exoskeleton. The only soft spot Brontoscorpio had in its exoskeleton which could be exploited as a 'chink in its armour' was its open mouth.

Brontoscorpio also had 2 pairs of pincers, with the larger pair used for grasping prey and the smaller used for tearing it apart. Brontoscorpio had evolved strong jaws for crushing and tearing apart the tough armored body of its prey. Not only could it breath underwater with gills, but Brontoscorpio could also come onto dry land and absorb air it with its primitive book lungs, which were made up of hundreds of thin layers of tissue. Being unable to breathe in and out like humans do, Brontoscorpio only absorbed oxygen into their blood stream. 

Like some modern arthropods, Brontoscorpio had to moult if it grew to large for its exoskeleton. The process of escaping its body would take approximately a day to complete and afterwards, Brontoscorpio would be vulnerable to attack as its skin would be soft. 

Their style of hunting was to stab its prey with its huge stinger and to inject it with a highly toxic venom. The venom would paralyse the victim and with multiple jabs of the stinger, the prey would be dead within a matter of seconds.

Equipped to maximize oxygen, and with their armor to protect them from the sun, these sea scorpions often patrolled the shorelines, scavenging on whatever the seas washed up. However, there were times where some Brontoscorpio couldn't feed because they often became prisoners in their own skin. Their rigid skeletons became a handicap and thus, it couldn't grow with their bodies. They needed to shed their hard skin, and then grow another, expanding while the new one is still soft. For such a large creature, this was a long process.

Venom Edit

Brontoscorpio's large stinger on its tail would inject deadly venom into other animals with one sting, which could weaken and paralyse stung animals such as humans, and then kill them through causing heart failure. The symptoms of Brontoscorpio poisoning and the speed at which the venom took effect depended very much upon the dosage injected: a direct sting such as a stab would bring the victim down instantly and kill it within seconds, whereas an indirect sting such as a shallow scratch would gradually weaken, numb and then kill the stung victim over the course of a matter of hours.

BehaviorEdit

As one of the sea scorpions, Brontoscorpio was one of the top predators of the Silurian Seas and prey was plentiful in their seabed hunting ground. Whenever they were on land, Brontoscorpio patrolled the shorelines, scavenging on any carcass that came from the sea. Surprisingly, these sea arthropods also lived in large numbers.

Brontoscorpio was a carnivorous predator, one of the apex predators of the Silurian period. Mainly a solitary animal, Brontoscorpio spent most of its time hunting small marine animals like trilobites and jawless fish like Cephalaspis individually. However, they occasionally banded together in colonies during the Cephalaspis breeding season to catch Cephalaspis en masse. Although Brontoscorpio was a fierce and lethal predator, it too was prey, therefore it had its own predators. Large eurypterids, like Pterygotus, included the scorpion on their menu.

Brontoscorpio was among the first animals to walk onto dry land. However, moving onto land for Brontoscorpio was a rare thing as most of its activity was under water. One of the reasons this scorpion went onto dry land was to feast on Cephalaspis migrating to their spawning grounds. Another is that they came on land to escape predators and molt its shell. At 3 feet long, it would take hours for a Brontoscorpio to molt its shell.

Surprisingly, Brontoscorpio could also scale walls, ceilings, and other surfaces much like a spider. Brontoscorpio made their home in caves and burrows, and they also made use of hidden sinkholes across the land in their territory as sandtraps to trap unaware animals for the Brontoscorpio to come for, similar to Trap-Door Spiders.

Brotoscorpio would attack victims with its large stinger on its tail to inject and incapacitate them with its deadly venom in just one sting, which could weaken and paralyze stung animals such as humans, and then kill them through causing heart failure. Then, they would drag the attacked prey's body away to suck out and consume their internal organs after the venom killed them.

It would seem that Brontoscorpio preferred to attack prey that were either alone or off-guard, although it would engage an organized group of other animals in a direct fight if it had to. Brontoscorpio displayed some similar caution and attack strategy to some modern day scorpions; approaching prey tensed and cautiously, and momentarily backing away slightly at movement, resistance and aggression from the victim.
