During the Dinosaur Age, Humans had lived during these times...with dinosaurs being top at the food chain with humans still being just cavemen...but there were few exceptions who were born with bodies that can even rival the strongest Dinosaur walking the planet...T-rexs, but there was only very few who was bron with that gifts. Tribes were form to increase the chances to live..but some would live as a lone wolf or die...it is your decision to choose your fate...good luck survivor...
