Book excerpt: Seventy million years ago in what would become North America, a monstrous thirty-five-foot-long Cretaceous crocodile lurked on a marshy riverbank. Springing suddenly, its huge jaws trapped and crushed a juvenile hadrosaur. Today, the remains of that ancient crocodile are being painstakingly reconstructed in Colorado, where naturalist Zach Fitzner continues his life-long fascination with this amazing animal family. In Tears for Crocodilia: Evolution, Ecology, and the Disappearance of One of the World's Most Ancient Animals, Fitzner tracks the evolution of crocodilians from prehistoric predators to modern endangered wildlife, using his own experiences with these reptiles as a lens to understanding wildlife conservation and our relationship with the natural world. Traveling the world to interact with crocodiles, from observing alligators in a wildlife refuge in Texas and paddling a canoe in the Everglades searching for crocodiles to trekking the jungles in Nepal to find endangered gharials, the author expresses a wonder in exploring these diverse ecosystems, making a connection between crocodilians and the lands they live in. As the story follows crocodilians, it also illuminates their often complicated relationship with humans, from crocodile cults in ancient Egypt to American alligators living on golf courses. Fitzner also closely examines the dark side of this relationship, including habitat destruction and poaching as well as the mechanistic view of traditional conservation that turns these magnificent animals into agricultural products. Tears for Crocodilia delves deeply into issues of wildlife conservation, ethics, and how we can coexist with other creatures. It is also a tribute to a magnificent group of animals, survivors from the age of dinosaurs.
