"As the co-discoverer of the first known burrowing dinosaur and a popular science author, Anthony J. Martin is an expert at explaining his fossil-finding work to broad audiences. In this engaging book, Martin uses modern and fossil traces to introduce readers to a menagerie of animals and other lifeforms that dig, crunch, bore, and otherwise reshape our planet. We meet elephants that dig ballroom-sized caves alongside volcanoes, parrotfishes that chew coral reefs and poop out sandy beaches, dinosaur-eating crocodiles, and moon snails that drill into clams, or even other moon snails. In a detective story that spans millions of years, ranging from microbes to whales, Martin shows how when life got hard, life got boring, using bodies and behavior to hide, eat, attack, and defend, affecting both our world and our understanding of evolution, climate, and life itself"-- Provided by publisher.
