Step onto volcanic plains and watch thundering herds of dinosaurs crash through thick forests. Dive into a sea of glass reefs, emerging from the water to see monkeys fighting for survival on an accidental raft . . .

Travel millions of years into the past, and explore worlds you might only have dreamt of, but that actually existed.

From woolly mammoths to early humans, find out how plants and trees and creatures great and small shared a world very different from our own.

And uncover the footprints they left behind . . .

Starting with the last ice age and ending when the very first animals started to swim and hunt, this illustrated journey back through time is adapted from the bestselling Otherlands by Thomas Halliday. It is written by the author, with illustrations by Gavin Scott.
