What it does

The mod is the Triassic Dimension add-on for Prehistoric Nature and generates a dimension themed on the Triassic period. It requires MixinBooter, Prehistoric Nature and Roughly Enough IDs, and every installation needs all three. Because Roughly Enough IDs is required from version 2.0 onward, it must be present alongside the rest. Installation covers the server and each player's game. Files are published for Forge 1.12.2 only, with 5.0 as the latest file from 2025-12-05. The code is not open source, and the mod is released under All rights reserved.
