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.
Craft a steampunk blimp and travel the world, take your friends with you too. The blimp allows for several people to travel together. You'll need fuel and water to propel it, and it can be customized by coloring it.
