ZOOLOGY OF FOSSIL REMAINS 99 



recent ones, carefully shaped with skill and artistic 

 feeling; Palaeoliths, very ancient, rude, but evidently 

 shaped by design; and Eoliths, rough stone chips 

 bearing evidence of use and indicating the existence 

 of man of less developed skill. These latter imple- 

 ments carry the trace of a tool-making creature back 

 into the Tertiary period. 



Besides the stone implements there are many 

 sketches of extinct animals by prehistoric artists, 

 scratched on bone, ivory, horn, slate and on the walls 

 of caves. The inference to be drawn from these 

 sketches is that man was alive in Central and South- 

 western Europe when the hairy mammoth and the 

 reindeer occupied the same territory. The crude 

 sketches of palaeolithic man, just referred to, merge 

 by gradations into the more carefully drawn, and 

 sometimes colored sketches, of Neolithic man. Those 

 of the cave of Altimera, in Spain, are very notable 

 products of Neolithic artists. 



The range of discovery of fossil human relics gives 

 evidence of a wide geographical distribution of 

 primitive races during palaeolithic times. Variations 

 in the degree of skill in the manufacture of stone 

 implements, as well as in other particulars, have 

 brought to archaeologists the recognition of different
