Prehistoric Fauna
Prehistoric Fauna is a Forge and NeoForge mod that adds travel to prehistoric eras, where extinct animals and plants still live in recreated landscapes.
What it does
Players reach past periods through portals and time travel, entering dimensions built on three Mesozoic periods. Each period's biomes are meant to match the geological formations of that time. Surviving in these landscapes is the core of the mod, and the worlds are meant to be explored rather than only passed through.
The mod adds 21 extinct species, from early ancestors to dinosaurs and mammals, including Chromogisaurus, Exaeretodon, giant forms and Cretaceous animals such as Triceratops and Tyrannosaurus. It also adds 7 unique trees and 12 unique plants. The mod is client and server, so servers and every player need it. Files cover 1.16.4, 1.16.5 and 1.20.1, and the license is All rights reserved. Prehistoric Revival - A Prehistoric Fauna Add-On requires it.
