Find every Fossil on your Minecraft seed — Java 26.3 & Bedrock 1.26.62, any seed, free, no sign-up.
Quick answer: Fossils are buried bone-block skeletons that generate underground in desert, swamp and mangrove swamp biomes, occasionally laced with Diamond Ore. Half of worlds have one within 1,150 blocks of spawn on Java and 1,150 on Bedrock. This finder marks fossil locations at a measured 95% accuracy on Java and 94% on Bedrock; diamond fossils carry their own measured figure on the marker.
Fossils generate underground beneath desert, swamp and mangrove swamp biomes in the Overworld, both above and below Y 0. They are built from Bone Blocks (with a little Coal Ore, or Diamond Ore in the deep ones) arranged as giant spines, ribcages and skulls, buried in the stone and deepslate. On Bedrock, mangrove swamps get only the deep, diamond kind.
Usually more than 1,000 blocks. Across 200 random worlds, half had a fossil within 1,150 blocks of spawn on Java and 9 in 10 had one within 2,600; on Bedrock the same figures are 1,150 and 2,600. About 4 worlds in 10 have one within 1,000 blocks: fossils are common under deserts and swamps but nowhere else, so the distance mostly depends on how far the nearest desert or swamp is. Open a marker for coordinates and dig down at that X/Z; following a cave or ravine to the right depth is often the quickest way in.
| How close | Java 26.3 | Bedrock 1.26.62 |
|---|---|---|
| Half of worlds have one within | 1,150 blocks | 1,150 blocks |
| 9 worlds in 10 have one within | 2,600 blocks | 2,600 blocks |
| Worlds with one within 1,000 blocks | 4 in 10 | 4 in 10 |
| How many within 1,000 blocks, on average | About 12 | About 11 |
Measured with this finder on 200 random worlds in each edition, from the point where each world spawns you. Distances are rounded.
A fossil is a free supply of Bone Blocks for bone meal, plus a little Coal Ore. In fossils that generate at diamond depth, that ore is Diamond Ore instead — the "diamond fossil" the finder flags separately — making the trip doubly worthwhile.
Yes — both editions, Minecraft 26.3 (Java) and 1.26.62 (Bedrock). Fossil markers publish a measured 95% on Java and 94% on Bedrock. The diamond-fossil variant is scored separately and carries its own figure on the marker — higher than the plain fossil on Java, lower on Bedrock — so open the marker you actually plan to travel to and read the number there.

What's inside: Bone Blocks (and some Coal Ore) shaped like spines, ribs and skulls; deep fossils carry Diamond Ore in place of the coal
