Here are the official ZT1: Dinosaur Digs species and their ZT2 counterparts(please note that all are fan-made): So here I will write what ZT2 lacks(for now) compared to the original game in regards to its prehistoric/extinct animal expansion pack(I count both all Blue Fang vanilla features and all third-party mods/downloads).ġ.Most of the animal roster so far has been made. I tried to ask the creators of Cretaceous Calamity some questions, but they ended up sounding more like a wishlist.
