The ankylosaurus lived during the Late Cretaceous period (70-66 mya). They were about 26 - 33 ft. in length which is about the length of a school bus and they weighed between 8,000 and 17,000lbs. They could only run about 6 mph because of their weight, however large bony plates covered most of its body and a heavy club at the end of their tail allowed them to defend themself from predators.
