Fossil is a Mineral that can be found at the bottom of the map in the Oil Biome in moderate quantities and in small amounts in the Tide Pool Biome. It can be used as a general construction material.

Usage[]

Although general buildings can be made out of Fossil, its main purpose is to be used in the Rock Crusher to convert into Lime for Steel production as an alternative to Egg Shells. Unlike most other items used in the Rock Crusher, Fossils do not break down into Sand; instead, they produce Lime and Sedimentary Rock.

100 kg Fossil = 5 kg Lime + 95 kg Sedimentary Rock.
