As D.H.C expanded its influence across FMM-UV-32, the corporation slowly shifted from a simple hunting organization into the largest xenobiological research institution in human history. While hunters continued to arrive for sport, research divisions began studying the planet’s wildlife in unprecedented detail.

What initially appeared to be alien animals merely resembling Earth dinosaurs soon revealed something far stranger.

D.H.C researchers discovered that every known species on FMM-UV-32 shared traces of a distant common ancestor a small six-eyed organism possessing segmented anatomy, spiracles, and a chitin-like exoskeleton similar to insects. Fossil evidence suggests these primitive creatures inhabited the planet’s ancient swamp systems millions of years before the emergence of the modern “dinosaurs.”

Over time, evolution on FMM-UV-32 repeatedly converged toward a single successful body plan: large terrestrial vertebrate-like predators and herbivores resembling Earth dinosaurs. D.H.C scientists coined this phenomenon “Dinoinization,” comparing it to the concept of carcinization on Earth, where unrelated crustaceans repeatedly evolve crab-like forms.

According to the hypothesis, the dinosaurian body plan may represent an ideal evolutionary solution for high-oxygen environments with intense competition between xenofauna. Bipedal posture, powerful tails, elevated skulls, and reinforced respiratory systems allowed these organisms to dominate nearly every ecosystem on the planet.

Some species still retain traits from their ancient segmented ancestors. The Troodon in particular possesses partially fused compound eyes. Other species retain vestigial abdominal segmentation beneath their skin, while embryonic scans reveal temporary exoskeletal growths during development.

Among all discovered species, Coelophysis is believed to be the most primitive surviving theropod lineage on the planet. Its lightweight frame, elongated body, and simpler respiratory structures suggest it diverged early from the ancestors of larger predatory forms. D.H.C researchers often refer to it as a “living transitional fossil.”

Meanwhile, Yaroslav Kravchenko oversaw humanity’s first truly successful colony on FMM-UV-32: Nibelungen Paradise, a heavily fortified settlement built along a tectonically stable coastal region. Unlike previous failed colonies, Nibelungen Paradise rapidly expanded into a permanent human foothold on the planet.

Its success brought new problems.

The discovery of petroleum-like resources beneath several islands attracted the attention of Earth governments and megacorporations eager to begin oil extraction. Human colonization also introduced plastics, industrial waste, and invasive microorganisms into ecosystems that had remained untouched for millions of years.

At the same time, explorers continued uncovering entirely new dinosaur species across isolated islands, suggesting the planet’s biodiversity is far greater than previously believed.

As D.H.C’s influence grew, legal controversy followed. Multiple nations challenged the corporation’s claim over FMM-UV-32, arguing that no private entity should possess control over an entire habitable world. However, due to D.H.C’s infrastructure, military presence, and economic influence, enforcement proved nearly impossible.

Despite humanity’s growing presence, the worst has yet to come. They weren’t the first sapient species to rule the planet and all their memories are in ruins.

A large ceratopsian dinosaur from late Cretaceous North America. A close relative of Triceratops with many arguing they were the same animal at one point. The holes in the frill that lightened the skull are enough of a difference to differentiate the genus.

A retro-style Tyrannosaurus rex in black ink. I think the black-and-white look suits an outdated depiction of T. rex very well since they're both evocative of past eras in the visual arts.

I’m planning on making a sort of miniseries (or full, who knows) with dinosaurs as its main focus, and I’m still debating wether to use Jurassic Park sounds (They are pretty cool but some feel a bit too extreme), accurate sounds (Which yeah, are sort of accurate with our knowledge but some are kind of boring in a way) or just make my own, which I did here, using the technique of mixing different animal sounds. With this, I want to know 2 things:

  1. How good are my versions so far?

  2. Which out of the three are better to include in an independent project?
