Fossil World is a relatively simple modpack based around the mods Fossils and Archeology Revival and the Thermal suite.
Here, you are free to go mine Fossils, analyze them for DNA, which you can then cultivate into various prehistoric Eggs.
These dinos or other creatures won't survive on their own though! You will have to take care of them as pets, so they can thrive and reach their full potential.
You various esthetic mods, such as Chisel, Earthworks, Rustic or Quark to help you build the nicest enclosures for your new friends. Use your powered technology from Industrial Foregoing to automate farming food, so they don't starve and build a functioning self-sufficient system, using the Laser Miner and other methods. Trains from Railcraft can always be a big help for long-distance transport.
This modpack is a more of a collection of mods, so far, no recipes have been altered, though that may change in the future. It is not meant to be hard, it simply exists, so you can play with the Fossils and Archeology Revival mod, alongside a few others.
You can find the modlist here. It also includes Nutrition by WesCook.
