Overview
Nether fossils exist to solve one problem, and it is a problem most players do not know they have: bone meal without skeletons. A large bone-block ribcage jutting out of the soul sand gives you hundreds of bone meal for the cost of a pickaxe swing each, which is enough to bone-meal a tree farm, force sugar cane, or dye a wardrobe white, and it takes minutes rather than an evening at a skeleton spawner. The complication is the neighbourhood. Soul sand valleys run the highest ghast and skeleton spawn rates in the Nether, the soul sand itself slows you to a shuffle exactly while a ghast is lining up a fireball, and the blue fog cuts your sight distance to the point where you hear the shot before you see it. Approach along the top of the fossil rather than the valley floor, put a wall of cobblestone between yourself and the open air, and mine from cover. There is nothing else here — no chest, no spawner, no hidden chamber — so once the bone blocks are in your inventory there is no reason to stay in the most hostile biome in the dimension.
Bone blocks by the stack, each crafting into nine Bone Meal, without killing a single skeleton. The blocks are also a striking pale building material against blackstone and netherrack, which is why many Nether bases are built around a fossil rather than near one.
A large bone block skeleton protruding from the soul sand of a soul sand valley, resembling a fossilised ribcage or spine. It contains no loot and spawns nothing, and its whole purpose is as free bone blocks — an easy stack of bone meal for a farm without killing a single skeleton. Soul sand valleys already have the highest ghast and skeleton spawn rates in the Nether, so the harvesting itself is the risky part.
It is uncommon in the The Nether, restricted to Soul Sand Valley, and it generates at roughly Y=32 to Y=100 within soul sand valleys.
How to get it
Nether fossils are uncommon and generate only in soul sand valley biomes, roughly between Y=32 and Y=100, protruding from the soul sand rather than buried in it. A single valley normally holds 2 or 3, and the white bone against dark blue sand is visible from a long way off.
Tips
- Mine from the top of the fossil, not the valley floor, so soul sand never slows you while a ghast has line of sight.
- Place a two-block cobblestone wall on the open side before you start; fireballs cannot round a corner and ghasts lose interest.
- Take the whole skeleton in one trip. Coming back to a soul sand valley twice is worse than carrying a heavy inventory once.
- Skeletons here are ordinary skeletons, not wither skeletons, so a shield handles them and you need no Wither protection.
Version notes
Added in 1.16 when soul sand valleys were created, six years after the Overworld fossil introduced the bone block in 1.10. The structure has not changed since.
Properties
It generates in the Nether, where one block of travel covers eight in the Overworld, water evaporates on placement, and beds explode instead of setting a spawn point. In a world with cheats on, /locate structure minecraft:nether_fossil gives the coordinates of the nearest one. Without cheats, an explorer map from a cartographer villager is the reliable route for the structures that have one; everything else is exploration.

Where it generates
Nether Fossil generates in one biome: Soul Sand Valley. Outside those it will not generate at all, however far you travel.
Notable loot
Its loot includes Bone Block. These are the notable entries rather than the full loot table — the common filler (bread, coal, iron nuggets) is omitted, and in some structures the best of it comes from a vault or a spawner rather than a chest.
Mobs found here
Skeleton, Ghast, and Enderman generate here. Several of them spawn nowhere else, which is usually the reason to make the trip.
What to watch out for
3 things to prepare for before you go in:
- Soul sand valleys have exceptionally high ghast and skeleton spawn rates
- Soul sand slows you while you are being shot at
- Soul fire and blue fog obscuring the view

Frequently asked questions
Do nether fossils have loot chests?
No. The bone blocks are the entire reward, and there are no mobs or spawners generated as part of the structure itself.
Are nether fossils different from Overworld fossils?
Only in location and shape. Both are made of bone blocks; the Overworld version is buried in five specific biomes, while the Nether version sits exposed in soul sand valleys.
Why are soul sand valleys so dangerous?
They combine the Nether's highest ghast and skeleton spawn rates with soul sand that slows your movement and fog that hides what is shooting at you.
How do I find Nether Fossil?
Nether Fossil generates in the The Nether, only in Soul Sand Valley, and is uncommon. /locate structure minecraft:nether_fossil finds the nearest one instantly with cheats on.
What loot is in Nether Fossil?
The notable entries are Bone Block.
When was Nether Fossil added?
Nether Fossil was added in Java Edition 1.16.
