“It is in the best sense a source book, for it gives at first hand, from the original material, the ideas of an acknowledged master in mammalian palæontology.” “It has the clarity and directness of style so welcome, and rare, in such a book.”—E. C. Case, in Bulletin American Geographical Society, July, 1911.
“A book of the utmost value to the student and teacher of mammalian life and likewise to the serious reader.”—American Journal of Science, Feb., 1911.
“M. Osborn ... devait s’attacher a nous présenter le tableau aussi complet et aussi fidèle que possible des faunes de Mammifères fossiles qui se sont succédé dans l’hémisphère Nord pendant l’ère tertiaire. Et j’ai plaisir à dire tout de suite qu’il y a parfaitement réussi.”—M. Boule, in Mouvement Scientifique, 1911, p. 569.
“Professor Osborn has produced a book which will appeal to the learned specialist and to the thoughtful general reader as well.” “The work is well adapted to school and college use, and is abundantly illustrated.”—Education, Boston, Jan., 1911.
“One of the most notable books on evolution since the appearance of Darwin’s ‘Origin of Species.’”—Forest and Stream, Dec. 10, 1910.
“Nejlepší současný palæontolog americký, Henry Fairfield Osborn, vydal nedàvno s titulem tuto citovaným znamenitě psanou a pěkně vypravenou knihu o ‘věku ssavců.’”—F. Bayer in Věstníku Ceské Akademie císaře Františka Josefa pro vědy, slovenost a umení.—Ročník XX, 1911.
“Written with clearness and vivacity, most admirably illustrated, especially by the ‘restorations’ of Mr. Knight, and illuminated by maps, Professor Osborn builds, page after page, his story-mosaic.... The reader will soon discover that he is a brilliant generalizer, possessed of material gathered from all around the globe, fructifying his knowledge by the exercise of a constructive imagination, and expressing his facts and ideas in a literary style, clear, vigorous, and entertaining.”—The Literary Digest, Feb. 4, 1911.
