Dinosaurs roamed Earth for more than 150 million years.
During their lives they would have wandered freely, looking for food, until they came across a natural barrier like the sea or cliffs.
Today man-made obstacles such as roads and fences often get in the way of wildlife, making it more difficult to find food and shelter. The Royal Society for the Protection of Birds (RSPB) have a guide on how to create nature highways and byways to help wildlife in and out of your garden.
