In multiple files, nether fossils are listed with other structures that can be located through /locate
. It is also assigned a string that the command would accept, Nether_Fossil
. The other structures listed here are only /locate
-able structures.
I'm not sure if this information would differ based on the program used to deobfuscate the code, but the file names where I found this were Feature.java and StructureFeatureIO.java.
This seems to imply nether fossils were intended to be compatible with /locate
, or that this was leftover on accident.
