Complex Ocean

See also: Organic, Archaean, Aerobic, ComplexOcean, Simple Land, Complex Land, Extensive

Complex ocean life is common, including everything up to vertebrates. The land will be still mostly barren at this point, though some animals may have life cycles which involve the land. Note that this is the first level where the world can be said to have native animals.

This is pretty much equivalent to the Cambrian period and onwards (the start of the Phanerozoic eon), and represents a sudden surge in diversity of life forms. It lasts about 100 million years.


Marine life is flourishing, and so there are many different types of marine resources. Most of the basic ones available previously will have been subsumed into the food chain or evolved into something more complex.
