GWC 5C

This classification resembles Terra’s Late Ediacaran and Early Cambrian Periods (ca. 600 – 450 million years ago).

These planets are located in the system’s “Goldilocks Zone”, have abundant water, a NiOx atmosphere and the temperature averages are between 85% and 105% of Terra’s. They are an excellent candidate for Terraforming.

Lifeforms on this type of planet consists of simple multicellular animals, and a variety of macroscopic marine plants, no true land plant exist. However, biofilms and microbial mats normally are well developed on tidal flats and beaches, and further inland may be a variety of lichens, fungi and microbes forming microbial ecosystems, comparable with modern soil crust of desert regions, contributing to soil formation.
