Gnathosimilidon

Information
In the aftermath of a mass extinction event which sent the tetrapods goodbye, much smaller creatures found their chance to shine. Three-hundred million years after the influence of man, some springtails, like Gnathosimilidon gorgops, have grown much larger to occupy the available niches in the beginnings of the Pentozoic. This giant carnivorous springtail shown has found itself to be the local apex predator. Growing as tall as a man and chasing after its prey using six legs held beneath its body, a running Gnathosimilidon gorgops is a fearsome sight to behold. Unfortunately, you wouldn't behold this sight for long, as its speed is surprisingly quick and it effectively crushes and dices up its food using false tooth-like projections at the front of its mouth, which function comparably to those of the extinct placoderm Dunkleosteus terrelli. In addition to this, Gnathosimilidon gorgops may use the furculas underneath its tail to help propell itself closer to its prey, often as a pounce-and-ambush tactic.

Design
Gnathosimilidon gorgops has four jawlike mouthparts, which function together as a mouth. Six long-and-bulky legs help it to run and it has two furculas underneath its tail. The collophore of Gnathosimilidon gorgops, inherited from its much smaller ancestors, is comparatively smaller to prevent loss of moisture. Although its environment is colder than today's due to the lower amount of carbon dioxide, vascular plants still live on and so some of its filaments are green for camouflage. It has filaments ranging from white to tan to orange to brown to green and to black to help break up its body shape so prey do not easily notice it. There is slight countershading, with the top pattern being slightly darker than the bottom pattern. Some areas have black spots and white spots to help with this breaking effect.
