Long Primordius Period

Era beginning/end

This is a period of little evolutionary change of the primordius life. Over this time atmospheric density, temperature and meteorite impact size and intensity decline slightly and gradually.   Early Primordial Eon
----> Mid Precellular Era
--------> Long Primordius Period

This is a harsh, unstable time for early life. Meteorite impacts and intense volcanic activity frequently threaten to eradicate all self-replicating molecules descended from the first primordius. However the intense volcanic activity also keeps these molecules plentiful enough that they can hang on after a cataclysmic event, as their hydrothermal vent chamber habitats are found in great sprawling networks globally across Oxidi's oceans.
