These rules will allow you to re-create what might have taken place all those eons ago. Please keep in mind that these are only "house rules", they are not official rules of any kind. As such, you are free to tweak these rules to best fit your games. We'll start with the 'thunder lizards' themselves, then move on to 'cavemen'.
DINOSAUR RULES
1. The following Kingdoms are allowed for dinosaurs: Amphibian, Mammal, Ornith, Reptile, and Benthic.
