IMAGINE you are out in space looking down on Earth. Through your viewfinder you can see the whole globe. Now – zoom in. What can you see now? Seas, mountains, plains, valleys, lakes... Zoom in some more. Forests, scrubland and wetlands come into view.
But there are no cities, no roads, no farmland, no sign of any human habitation whatever.I Train your viewfinder anywhere on the Earth's surface and it's the same story. For this is planet Earth as it was 150 million years ago: the Jurassic Period. And if you zoom some more, you will soon come across the creatures whose domain this was in those times. In fact, they were the most awesome creatures that ever walked on this planet: the dinosaurs.
Look for the viewfinder on each illustration. Then turn the page
to see what you’ve zoomed in on next.
Witness a titanic contest between a giant, long-necked dinosaur and its terrifying predators.
Glimpse those smaller inhabitants of the dinosaur world as they dart
through the undergrowth. Finally,discover a nest hidden away in that
undergrowth, and find a tiny dinosaur embryo inside that egg.
