Six months. One prehistoric world.

Reconstruct a complete prehistoric ecosystem for film — not a single hero creature, but the animals, the landscape they moved through, and the light that fell on both. Prehistoric work fails in a specific way: the creature is convincing on its own and wrong the moment it stands in its environment, because the two were designed by different logic. The brief was to make one world where every element obeyed the same evidence.

Six months, beginning before any frame was generated. The megafauna record was read for what it actually constrains — skeletal proportion, mass distribution, gait, and the soft tissue that can be inferred from bone and what cannot. Landscape and vegetation were treated the same way: a period-plausible environment rather than a generic wilderness. Where the record was silent, the inference was documented as inference and carried consistently, instead of being quietly decided shot by shot.

Paleontologists on skeletal inference and soft-tissue plausibility. Archaeologists on landscape and material evidence. Color-science specialists on palettes grounded in preservation evidence rather than guesswork. Each specialist reviewed the work in their own domain, and the notes changed the design rather than decorating it.

Forge OS planned every output before generation, against the realism standard the research had established. It held each creature's identity constant across shots, so anatomy that had been argued for once did not drift in the next sequence; it governed the world with one internal law for light, physics and aftermath from concept frame to final frame; and it measured the delivery against those standards before it left the studio.

A prehistoric ecosystem delivered as finished artifacts — creature work whose anatomy is held to the fossil record and documented inference standards, and environments that follow one consistent natural law from concept to final frame.
