"The Age of Mammals" is not written for the palaeontologist only. 

 No zoologist interested in mammals, birds, fishes, or reptiles can fail to find 

 it of value. The geologist finds here the clearest exposition that has been 

 given of the succession of geological events in the mammal-bearing con- 

 tinental formations of the Tertiary and Quaternary of the Western States. 

 The anthropologist finds in the closing chapter on the Pleistocene a key to 

 most of the problems which confront him as to the time of man's first ap- 

 pearance. The botanist may refer to it for the succession and evolution of 

 flora. 



To the general reader it offers the first connected account of the history 

 of life on the earth during the later geological epochs, a record embodying 

 the very latest results of the active research going on in this direction at 

 the present time. In so far as science has succeeded in piecing together the 

 fragmentary evidence of the rocks, this volume contains glimpses into the 

 remote past of the continental outlines, the climate, vegetation, and animal 

 life of the epochs preceding the "Age of Man." The text is supplemented 

 by a very original and suggestive series of illustrations, notable among 

 which are numerous half-tone reproductions from the famous restorations 

 of extinct mammals by Charles R. Knight, many of which are published 

 here for the first time. Moreover, there is appended to the volume an in- 

 valuable Classification for the Mammaha, which gives not only the sys- 

 tematic position but also the geologic and geographic distribution and the 

 popular names of all the important genera of mammals, both living and 

 fossil.
