This particular Albertosaurus is part of an exhibit at the Calgary Zoo - they have brought in 13 dinosaurs models that are animated - their heads move, mouths open to show their teeth, feet and tails move as well as roar as you pass by. They are spread out in a 6.5 acre badlands park with 20 other static models. It's fun to watch the reaction of the young kids as they go through the park.
