This book investigates the apparent conflict between scientific theories of dinosaur evolution and a literal interpretation of the Biblical creation account. Duane T. Gish, a prominent figure in creation science, presents arguments challenging evolutionary explanations for dinosaur existence and proposes alternative interpretations grounded in a young Earth creationist framework. The book aims to reconcile the fossil record of dinosaurs with a Biblical worldview, suggesting that dinosaurs coexisted with early humans.

The book is regarded within creationist circles as a significant contribution to reconciling dinosaur paleontology with a Biblical narrative. It is often cited by proponents of creation science for its detailed arguments against evolutionary theory and its support for a young Earth. However, mainstream scientific and paleontological communities generally regard Gish's arguments as pseudoscientific, lacking empirical support and contradicting established scientific consensus on evolution and the age of the Earth.
