Fossil

The fossil blocks look like stone, but are much harder than stone. Fossil blocks are found in all layers of stone, but are easier to find in cave systems. To successfully mine fossils they must be mined with either an iron or diamond pickaxe. Enchantment "Fortune" does not affect the number of items that can be dropped from mining the block. The fossil block has the chance to drop:
 * Bones-45% or 450 every 1000 Blocks.
 * Relic Scrap-20% or 200 every 1000 Blocks.
 * Bio-fossil-20% or 200 every 1000 Blocks.
 * Cobblestone-10% or 100 every 1000 Blocks.
 * Skull (Block)-3.1% or 31 every 1000 Blocks.
 * Broken Anicient Sword-0.5% or 5 every 1000 Blocks.
 * Broken Ancient Helmet-0.5% or 5 every 1000 Blocks.
 * Skull-0.2% or 2 every 1000 Blocks.
 * Claw-0.2% or 2 every 1000 Blocks.
 * Foot-0.2% or 2 every 1000 Blocks.
 * Leg bone-0.2% or 2 every 1000 Blocks.
 * Scarab Gems-0.1% or 1 every 1000 Blocks.
