The information in this article applies to Path of Exile on PC, Xbox and PS4.
Fossils are mostly found within the short side areas in the darkness, though they sometimes even appear in the area in which your cart can move.
Sometimes, Fossils can even spawn behind Fractured Walls, so you’ll have to destroy the Fractured Walls with Dynamite before you can access the Fossil spawn location.
Fossil farming is a quite common thing to do during new leagues, simply because Fossils can be quite expensive– being a really good money making method but in order to be an efficient farmer you have to know the Fossil locations and spawn rates.
There are currently a total of 30 different Fossils which spawn in certain Fossil locations aka Fossil biomes (within the Delve mine) and there are 7 of these Fossil locations.
