The deeper it is, the older it is.The Phanerozoic is subdivided into three eras, from oldest to youngest they are Paleozoic (“ancient life”), Mesozoic (“middle life”), and Cenozoic (“recent life”) and the remaining three chapter headings are on these three important eras.

Remnant 2 uses a level of randomization for Maps, so not every Map will look the same. The names of a World will always be the same -- N'Erud will always be N'Erud, Losomn will always be Losomn, and so on. However, the locations within each world may have different names. Take a look at these two different versions of the Map of Yaesha:The idea that the Earth’s crust is made up of oddly shaped puzzle-like pieces is known as plate tectonics.

These currents of the super-hot, molten mantle move the plates ...The Cambrian explosion.
