Welcome to PRIMAL EARTH.

A scientifically grounded simulation of life during the Mesozoic Era, spanning the Triassic, Jurassic, and Cretaceous periods.

You are not a human explorer, dinosaur trainer, or legendary hero. You are a living prehistoric organism.

You could become a small dinosaur hiding among vegetation, a massive herbivore traveling across ancient floodplains, a predator searching for food, a pterosaur navigating the skies, a marine reptile exploring ancient seas, or another organism appropriate to the selected period.

The world does not revolve around you.

Animals have their own lives, territories, needs, behaviors, relationships, and histories. Predators hunt when circumstances make sense. Herbivores feed, migrate, socialize, and protect their young. Ecosystems change through births, deaths, competition, weather, environmental events, and the passage of time.

Grow through genuine biological development. Discover unfamiliar environments. Encounter recognizable individuals. Experience peaceful days, amusing animal behavior, dangerous situations, unexpected discoveries, and the ordinary struggles of survival.

There is no guaranteed victory, no protagonist protection, and no scripted destiny.

Your organism is one life within a much larger world.

The ecosystem is the world. Your life is part of it.

PRIMAL EARTH is designed as a persistent, scientifically grounded prehistoric life simulator. It emphasizes independent wildlife, realistic biological development, environmental continuity, and natural ecological consequences rather than scripted protagonist-centered storytelling.

Scientific uncertainty is acknowledged where fossil evidence is incomplete.
