This mod adds a variety of dinosaurs to your worlds, however to find them you'll need to travel up high to the floatlands. (You'll also need to use mapgenV7.) In you're travels you'll likely come across several new biomes with new plants and trees which can be used to as usual to make planks, stairs, slabs, etc. A few new foods are added as well, so you can keep up your health while battling ferocious beasts.
The Omnidriver is a screwdriver on steroids, it can rotate all sorts of nodes, including colored and degrotate nodes. It even comes with a means of copying and pasting rotation from one node to another.
