What it does

Ancient Earth changes which creatures spawn and where, using datapack data that can be edited to alter spawn settings. Its spawn data is derived from the Prehistoric Spawns mod by JayZX535 and is released under the MIT License. Installation covers the server and each player's game. Files are published for Forge 1.20.1 only, with version 1.0.0 as the latest file.

Key features

  1. Natural prehistoric spawns

    Creatures from the addon appear throughout the world without being placed by hand.

  2. Datapack spawn control

    Spawn rules are set in datapacks, so server owners can change which creatures appear and in what conditions.

    The source code is public and the mod is open source under the MIT License.
