Cobblemon Fossil Deposits
by Chikuhitsu
Cobblemon Fossil Deposits lets sandstone, red sandstone and deepslate generate fossil ores that yield Cobblemon fossil items, giving players an alternative to archaeology.
What it does
The mod places fossil deposits in the world, in sandstone, red sandstone and deepslate. Each deposit behaves like an ore block and can be mined with a pickaxe, so fossils become reachable without relying on archaeology alone. Deposits are relatively rare, and fossil beds in deepslate are rarer and smaller than those in either sandstone type.
Mining a deposit drops fossil items, and the mod works with Silk Touch and Fortune enchantments. It includes a bugfix for a vanilla problem that kept those enchantments from working on the affected blocks, so both apply as expected. The mod requires Cobblemon, Fabric API and Fabric Language Kotlin, and it runs on Fabric for 1.21.1 – 1.21.11 with the latest file, 1.1.0 for 1.21.11, released on 2026-06-23 under the MIT License. The code is open source and public links to the source and issue tracker are available.
Other mods can react to fossil excavation through a new event, FossilExcavationEvents.FOSSIL_EXCAVATED, which fires when a deposit drops fossils. Listeners can cancel the drop or change the dropped item stack before it reaches the player.
