Ice Age fossils of mammoths, sabertooth cats, dire wolves and more, discovered in the La Brea Tar Pits in Los Angeles and displayed in the George C. Page Museum of La Brea Discoveries. This updated and reillustrated edition of the book tells the story behind the fossils and about life in the Ice Age when these animals were alive and examines the work of the paleontologists who excavate and study them. During the Ice Age, over 400 different kinds of animals lived on the grassy plain that is now Los Angeles. Then, as now, pools of tar sometimes seeped to the surface of the earth. Unwary animals stepped into the sticky tar and were trapped. There they died. Gradually their bones sank to the bottom of the tar seep. In time, the tar penetrated the bones and preserved them. This book tells the story of the Rancho La Brea fossils and examines the work of the paleontologists who excavate and study them at the George C. Page Museum in Los Angeles, California.
