Como Bluff in southern Wyoming was the site of the world's first major discovery of dinosaur remains. Othniel Charles Marsh, a palaeontologist for Yale University's Peabody Museum, financed the dig and claimed a large proportion of the fossils excavated. He reunited the excavated bones and had lithographs made of them. The story of his achievements was chronicled in 1966 in a classic book, Marsh's Dinosaurs: The Collections from Como Bluff by John H. Ostrom and John S. McIntosh. Most of the lithographs were also reproduced (an example, two views of a Stegosaurus sacrum, is shown above). The book has long been out of print, but is being reissued this month (Yale University Press, $85), with a foreword by Peter Dodson which places the discovery in historical perspective.
