MEGA-PREDATORS OF THE PAST

This nonfiction book looks beyond dinosaur-centered accounts of prehistory to examine other enormous predators. It introduces lesser-known ancient creatures, including giant insects and birds, and presents facts and theories about them. Many of the animals discussed were ancestors of species that still exist today. By focusing on their size, fierceness, and place in prehistoric life, the book offers a view of animals that roamed Earth long before the present day.
