Written in a lively, conversational style and illustrated with the author's colourful, scientifically accurate paintings and very funny cartoons, When Dinos Dawned, Mammals Got Munched, and Pterosaurus Took Flight takes readers back to a world sandwiched betwen two major extinctions – the end-Permian and the Triassic. In this period, dinosaurs began to flourish and mammals established their toehold on Earth, promising, despite peril, to survive.
