I believe that someone has deleted this page, so I will do my best to explain the main uses of a Fossil block. Sorry for the inconvience, I did not delete this page.
Fossils are the skin and bones of the mod. They appear semi-commonly underground in veins that amount to somewhere between the size of coal and iron veins. They can only be mined with an iron pickaxe or better.
Most of the time, a fossil will drop a bone. The bone is the same bone that a skeleton drops. This can be used for making bonemeal, increasing the size of placed bio-fossils, and crafting bone armor.
A fossil also has a chance to drop a block of cobblestone.
I believe that it is 20% of the time that a fossil will drop a bio-fossil. A bio fossil can be analyzed in the analyzer to uncommonly find Dinosaur DNA. It can also turn into bonemeal, sand, and I believe a few other things.
I also believe that it is 20% of the time a fossil will drop Relic Scrap. These can be analyzed to find gravel, flint, I think sand, and rarely broken ancient swords or helmets.
A fossil itself, I believe, can also drop vroken ancient swords or helmets
A fossil can also drop Skulls. These can be placed, crafted into five bonemeal, or turned into lit skulls when crafted with a torch, much like Jack o' Lanterns.
Last but not least, I believe that a fossil has a 0.01% chance to drop a Scarab Gem.
Again, I did not delete this page, I just wanted to get something out for the people who are new to this mod to read before the mod developers fix this page. It was deleted by someone, so it was blank, so I wanted at least something here.
Thank you for reading!
