Find every Nether Fossil on your Minecraft seed — Java 26.2 & Bedrock 1.26.40, any seed, free, no sign-up.
Quick answer: Nether Fossils are large bone-block skeletons that generate in Soul Sand Valley biomes in the Nether — a rich source of Bone Blocks. On Java this finder marks fossil locations at a measured 99% accuracy; Bedrock locations are shown as estimates. Since Java 1.21.6 and Bedrock 1.21.90, about one fossil in three also holds a Dried Ghast, which this finder marks with its own icon on Java 1.21.6+ and Bedrock 1.21.120+.
Nether Fossils generate only in Soul Sand Valley biomes in the Nether, partly buried in the soul sand and soul soil. They look like giant ribcages, spines and skulls built from Bone Blocks, and a Soul Sand Valley usually holds several.
Enter your seed and the finder marks fossil locations. Open a marker for coordinates and travel there in the Nether — the pale Bone Blocks stand out clearly against the dark soul sand and blue soul fire.
Each fossil is a large pile of Bone Blocks — mine them for a big stock of bone meal (nine per block) to fuel farms and composters, or build with the blocks themselves. There is no loot chest; the bones are the prize.
Yes — both editions, Minecraft 26.2 (Java) and 1.26.40 (Bedrock). Nether Fossils arrived in 1.16 (the Nether Update) on both. On Java, fossil markers are verified against real generated worlds and publish a measured 99% accuracy — Dried Ghast markers score the same on Java 1.21.6 and newer. On Bedrock their positions are still published as an estimate while measurement is pending.
Since Java 1.21.6 and Bedrock 1.21.90 ("Chase the Skies"), roughly one Nether Fossil in three generates with a Dried Ghast among its bone blocks — the block-form ghast that slowly rehydrates into a Ghastling if you place it in water. The finder gives those fossils their own Dried Ghast marker, so you can travel straight to one instead of checking every skeleton in the valley. Pick Java 1.21.6 or newer, or Bedrock 1.21.120 or newer, in the version selector to see them. On Bedrock 1.21.90 to 1.21.114 the fossils themselves still show, but we cannot yet work out which of them carry a Dried Ghast, so we mark none rather than guess.
