The Day of the Dinosaur

Blurb

The Day of the Dinosaur is a science book by L. Sprague de Camp and Catherine Crook de Camp, illustrated with plates. It was first published in hardcover by Doubleday in 1968, and in paperback by Curtis Books in 1970 or 1971. A second hardcover edition was issued by Bonanza Books in 1985. The first chapter was reprinted as "One Day in the Cretaceous" in the de Camps's collection Footprints on Sand.
As stated on the dust cover of the Doubleday edition, the work is a survey of "the exciting story of the lost world of the great reptiles and of the fossil hunters who discovered them millions of years later." It argues, among other things, that the theory of evolution took hold after Darwin because of interest spurred by recently popularized dinosaur remains, corresponding to legends of dragons.
