Sniffer period
by _Honey_guy_
Sniffer period adds a prehistoric dimension where ancient creatures, unfamiliar vegetation and new biomes share the world with the sniffers that give the mod its name.
What it does
The mod sets its content in an era when large lizard-like creatures still dominated the planet. A large sniffer population roams the new dimension, and the ancient mobs and vegetation found there are unique to it. Players can look for prehistoric creatures in special biomes that do not appear in the standard world.
Sniffer period brings new food and new items, including weapons for dealing with the creatures of this era. The content is all new to the game, so it does not replace existing vanilla mobs or biomes. Files are published for NeoForge only, covering 1.21.1 and 26.1.2. Either side can run the mod, and neither side needs it. The mod is released under the MIT License and is not open source. Documentation is available on its wiki, and the mod's files cover both game versions listed above.
Players who want the prehistoric setting can add the mod to a single-player world or a server, without changing how the standard overworld plays.
