Jurassic Park 4: The Super Blockish Dinosaurs

FA adds a variety of new blocks, items, mobs, and structures to Minecraft without overloading it.

First are the blocks. In order to get anything from FA, besides maybe living nautili or javelins, you need to find fossil blocks. These stone/cobblestone hybrids drop basically everything you'll need to thrive. There is also a block called permafrost. It also drops these items, but it will freeze any block around it unless it is melted. These starting items are skulls, biofuel, ancient relics, and the occasional broken sword/helmet/etc...

To use these, you have to build one of the new machines. You start with an analyzer. You insert rather biofuel, ancient relics, or frozen meats into it, and you will get 4 items from each one. You mainly do this in order to get prehistoric DNA, so that you can eventually grow your own dinosaurs( or mammels, there is now a sabertooth cat).
Try to conserve how often you do this; You'll need ancient relics to use in the archeologist's crafting table, which repairs broken items. The last item is a cultivator. You put DNA in along with meat or biofuel, and the output will give you a prehistoric egg( or embreyo for the sabertooth. Use it on a pig/sheep/cow, and it will give birth to a sabertooth)!

There are a large variety of dinosaurs, each with their own unique properties. You can create a dinoguide to use in game, or look at the download page for more info.

There are also new world structures. Underground, you can find ancient weapon shops, that have javelins hidden inside. On the surface, there are ancient academies, and in the sea there are sunken ships to plunder.

This mod is worth downloading, with the 4000 ids at your disposal, and a config file so that you can change id# if you need to, this mod is a must.
