The enthusiasm Piotr Naskrecki, an entomologist at Harvard University’s Museum of Comparative Zoology, feels for visible, tangible signs of Earth’s prehistoric past is irresistibly infectious. Combining lively first-person narrative with his own breathtakingly beautiful photographs, the author reveals the holdovers from a lost world (from horseshoe crab to horsetail ferns) that can be found across the globe or right in our own backyards.
