Produktbeschreibung
Excerpt from Report of the United States Geological Survey, Vol. 2: Of the Territories Office of the United States Geological Survey of the Territories, Washington, D.C., October 5, 1875. Sir: The very valuable memoir, by Prof. E. D. Cope, on the "Vertebrata of the Cretaceous Formations of the West," is respectfully submitted for your approval and for publication. The great interest which has been excited among the people, as well as among scientific men, by the discoveries of the remarkable extinct vertebrate remains, within a few years past, in the numerous ancient lake-basins of the West, will render the publication very opportune at this time, and one of great value to the intelligent world. As a contribution of materials toward the solution of the numerous problems involved in the geological structure of our great West, as well as the unfolding of its ancient life, it must take the highest rank. In a certain sense. Paleontology, or the history of ancient organic remains, lies at the very foundation of geological science. It oftentimes stands as the arbiter on doubtful questions, and is a very important aid to the stratigrapher in unfolding the age of strata, and in fixing the great time-boundaries of groups, as well as divisions or subdivisions. No geological survey can be considered complete without its cooperation. It has been with this idea that so much of the strength of the survey has been given to this department. So far as the opinions expressed by the author in regard to the age of the Lignitie group are concerned, he alone is responsible to the scientific world. In all the publications of the survey under my charge, prepared by collaborators of established reputation, I have thought it best to permit the broadest latitude in the expression of opinions, whether they harmonize with my own conclusions or not.
