A historical review of the most important scientific controversies that have shaped our knowledge of dinosaurs since the discovery of important fossils in the 1820s. In The Great Dinosaur Controversy: A Guide to the Debates, the major scientific disputes that have contributed to the understanding of dinosaurs come to light. Each chapter presents a major controversy then ponders the lessons learned and their impact on the scientific field. Colorful characters such as "anti-evolutionist" Robert Owen, "Darwin's bulldog," T.H. Huxley, and "dinosaur heretic" Robert Bakker, enliven the debates, which range from the origin of dinosaurs and their posture to their evolution or retrogression and whether they were warm- or cold-blooded. Two of the most recent debates concern how dinosaurs became extinct and whether or not birds are their descendents.

In 1980 Nobel Laureate Luis Alvarez announced his theory of the dinosaurs final demise: a gigantic meteorite crashed into the earth and raised a cloud of dust that caused darkness for years, suppressing photosynthesis, which impeded plant growth, and eventually starved the dinosaurs. This idea exploded into common awareness with almost unprecedented speed, and was instantly embraced by the media and the public. Almost without question, it quickly became the hottest scientific "fact". Unfortunately for Alvarez, many in the scientific community did to support this theory, and in fact later research showed the impossibility of such an idea. The Great Dinosaur Extinction Controversy chronicles the fantastic story of how this hypothesis became so widespread, the way it became "common knowledge" - from the pages of Science to The New York Times to Parade Magazine, the controversy it caused, and the ample scientific research that proves the theory wrong. Officer and Page also present an attractive and carefully investigated alternative explanation for the mass extinctions that occurred at the end of the Cretaceous period. Through this account they show the ways that sound science should be performed and the findings transmitted.

In Controversy, Trevor Palmer fully documents how traditional gradualistic views of biological and geographic evolution are giving way to a catastrophism that credits cataclysmic events, such as meteorite impacts, for the rapid bursts and abrupt transitions observed in the fossil record. According to the catastrophists, new species do not evolve gradually; they proliferate following sudden mass extinctions. Placing this major change of perspective within the context of a range of ancient debates, Palmer discusses such topics as the history of the solar system, present-day extraterrestrial threats to earth, hominid evolution, and the fossil record.
