Dramatic and amazing BBC series on the animals on the planet before dinosaurs ruled. From the makers of Walking with Dinosaurs and Walking with Beasts comes an epic and entertaining new exploration of life, revealing that in the age before dinosaurs, a succession of fantastical animals and plants ruled the planet. Most of us are completely unaware that these creatures ever existed, or believe our planet was home to just worms and bugs. Yet there was a time when a two-tonne predatory fish came on land to hunt, when four-metre sea scorpions sliced sushi in the shallows, when just one species of lumbering reptile represented eighty per cent of all life. For the first time, this series uncovers these creatures and the bizarre worlds they inhabited.
