The mighty T-Rex lived in the late Cretaceous, 68-65 million years ago. This guy was the most mighty of all of the predators, and is extremely dangerous. For your safety, we monitor the Rex family 24 hours a day, and have them extremely well guarded. One escaped a little while back, and was quickly apprehended doing no injury to anyone or any of the facilities. We started out with only one Rex, and we now have 5. We were surprised to learn that this "beast" is a loving nurturing, parent, and also that it likes to socialize, travelling and hunting in packs. Please do not go within 5 feet of their pen, or the consequences will be your own. Enjoy the rest of your tour, and have a nice day. Thanks for your visit.
