Amazon.com description: Product Description: This volume is in large part a reprint of various popular descriptions and notices in the American Museum Journal and elsewhere by Professor Henry Fairfield Osborn, Mr. Barnum Brown, and the writer. There has been a considerable demand for these articles which are now mostly out of print. In reprinting it seemed best to combine and supplement them so as to make a consecutive and intelligible account of the Dinosaur collections in the Museum. The original notices are quoted verbatim; for the remainder of the text the present writer is responsible. Professor S.W. Williston of Chicago University has kindly contributed a chapter—all too brief—describing the first discoveries of dinosaurs in the Western formations that have since yielded so large a harvest.
