More Fossils
Lets fossils generate in any biome, with more of them being found in the Deep Dark.
Quick answer
Which More Fossils release matches 1.21.4 Fabric?
More Fossils 3.0.1+mod targets 1.20, 1.20.1, 1.20.2 with Fabric, NeoForge, Quilt. Installation on the client is optional. Installation on the dedicated server is optional. 1 required mod needs a matching file.
Where it goes
Is More Fossils required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does More Fossils 3.0.1+mod need?
3.0.1+mod on 1.21.4 Fabric. Every mod below is checked against that same setup.
Install Lithostitched first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does More Fossils add?
Have you ever wondered why fossils are so rare? Turns out, they only generate rarely in desert, swamp, and mangrove swamp biomes. Most players won't ever encounter one throughout their playthroughs.
This datapack uses Fabric/Forge biome modifiers to allow fossils to generate in any Overworld biome. They aren't too common, but exploring big cave systems will give you a good shot at finding some.
Since this is done on top of vanilla fossil generation, fossils will be around ~70% more common in deserts, swamps, and mangrove swamps compared to other biomes. Similarly, fossils are about 160% more common in the deep dark compared to other biomes.
Configuration: If you want to edit the generation frequency of these fossils, make a datapack with the data/more_fossils/worldgen/placed_feature folder from the source repository and edit the corresponding json file. The minecraft:rarity_filter entry controls the rarity of a feature's generation, where a value of 30 corresponds to a 1 in 30 chance of passing through the filter (and a 29 in 30 chance of generation failing).
You can also go to data/more_fossils/tags/worldgen/biome to edit the tags that determine which biomes a fossil can spawn in.
