A paleontologist and a storyteller take two children through the birth of our planet, the beginning of microbes, and through the heydays of protozoans, dinosaurs, and early mammals with unfailing enthusiasm. The art accurately portrays animal species and prehistoric landscapes, includes maps and infographics, but also adds humorous touches: a google-eyed prehistoric fish looking startled to be walking on land and the children popping out of a tree top to surprise a Brachiosaurus. The combined expertise of author Jean-Baptiste de Panafieu, a science writer and biologist, and illustrator Adriene Barman, the creator behind Creaturepedia and Plantopedia, makes for a science read you can trust. Fans of Maris Wicks's Human Body Theater and Nathan Hale will be pleased.
