About this Mod

Banner

This mod was originally planned as an addition to the "Unusual Prehistory " mod created by "p33ko322131." All animations, mechanics, and skins are inspired by that mod, as well as other audiovisual media and updated versions of the base game.

Support for compatibility with the first version of "Unusual Prehistory" will be discontinued in order to focus entirely on "Unusual Prehistory 2" in future updates, but it will continue to function independently.

"REQUIRES GECKOLIB"

In this addon/mod, you will find a variety of unique mobs that will expand the prehistoric fauna in the game, as well as new structures that will generate in the world.

Requires " Natural Prehistory Spawns " to enable dinosaur spawning.

The current list of creatures is:

  • Dakotaraptor
  • Sinosaurus
  • Oxalaia
  • Charonosaurus
  • Latenivenatrix
  • Coahuilasaurus

The current list of structures is:

  • Dakotaraptor trapped in resin.
  • Oxalaia trapped in resin.

New creatures and structures will be added in future updates.

Extras:

  • Renaming a Sinosaurus "Dennis" will change it a special skin.
  • Renaming an Oxalaia "Sunset" or "Snock" will change it different special skins.

For additional information of creatures, consult the in-game encyclopedia.
