This was an earlier post that I made and I feel that it should be part of the game. I understand that there is already a mod like this but I feel that it is worth putting into the game. When I made this post, I was unaware that there was an archaeology mod.
I think that it would be neat if there were dinosaurbones in random places under the dirt. The bones would take a bit less time to mine than obsidian and the bones can be used in potions and can be crafted into armor.
