The life-sized animatronic dinosaurs from the TV special Walking With Dinosaurs are currently on a worldwide tour. Unfortunately, one of them seems to have vanished during a stop in Guadalajara, Mexico. Of course, it isn't an autonomous robot dinosaur, which means that it was probably stolen. So if you see a huge dinosaur charging at you, don't worry, it's only some thieves having a laugh. You aren't caught up in some kind of temporal anomaly, probably.
