Fossil
Overworld
How to find it
- Generates rarely underground in desert, swamp and mangrove swamp biomes - skull or spine shapes made of bone blocks
- Two generation attempts per chunk at 1/64 each: one range Y 0 to 320 (with coal ore), one Y -63 to -8 (with diamond ore below Y -8)
- No map and no /locate support for the small features - strip mine in a swamp or desert and watch for bone blocks
Loot
- Bone blocks
- Coal ore embedded in fossils above Y=0
- Diamond ore (Java) and deepslate diamond ore below Y=-8
Dangers
- Structure integrity 0.9: about 10% of the bone blocks are missing
- Deep fossils sit in deepslate layers with lava pockets
Tips
- Each chunk has two attempts at 1/64 (Y 0 to 320, and Y -63 to -8). Source: minecraft.wiki Fossil.
