A reconstruction of a Cambrian underwater environment, with consistent anoxic conditions. I imagined the lower oxygen levels to make for a greenish toned and murky environment where some interesting creatures like jellyfishes and trilobites actually thrived. In the movie you can see both a huge jellyfish passing by, and on the sea floor a group trilobites interacting, some fighting, other swimming or patrolling the the area, and a few jaw-less fishes, probably some conodonts. A cluster of kelp-like ancient plants and crinoids complete this rather barren and primordial environment.
All work done in Unreal Engine.
