Argentiferous Period

The Argentiferous Period is third period of the Plutolithic Era and seventh period of the Geologic Time Scale.



The most well-known rocks from this period are large deposits of silver (argentum) in territories of the former Sterling Crownlands. Temperatures during this period varied from a temperate +14°C during the inter-glacial periods to -12°C during the strongest ice ages, when Rathnir was almost entirely covered with glacial ice. This sub-period is also called "Frozen Rathnir". Regardless of ice ages on the surface, life still thrived underneath ice sheets in the sea. During this period, fungi and algae had evolved, marking the beginnings of highly-organized multicellular life. However the Argentiferous still had no multicellular animals, making the period the "age of Fungi-Algal dominance".
