The student should consult the numerous papers by Prof. Marsh in The American Journal of Science; and by Prof. Cope in The American Naturalist. Many of Prof. Marsh’s papers have also appeared in The Geological Magazine and in Nature. The two latter journals contain many other valuable papers (and reviews of Monographs, etc.), too numerous to be separately mentioned. Some are referred to in the text. The Quarterly Journal of the Geological Society contains many papers on Extinct Animals. See also papers in Natural Science and Knowledge.
