Everyone loves dinosaurs, but so many other groups of wonderfully weird (and often giant) animals used to roam the Earth too -- they just never had as good a publicist. The planet has seen tons of bizarre-looking mammals, which were closer to us both in biology and in time. What if they took a holiday from being extinct? Take a trip around the globe with these outlandish "time tourists" as they visit the modern-day places each species once called home. Colour your way through space and time and help make their travels brilliant!
