FURTHER STUDIES AT VERO, FLORIDA 683 



development of man has been traced from the mid-Pleistocene on, 

 the introduction of pottery by Neolithic man is not placed as far 

 back as the close of the Glacial period and is not, therefore, Pleisto- 

 cene as usually defined. There is no ground to suppose that 

 pottery was in use in North America before it was in use in the 

 Old World; more probably it was introduced here later. 



If (1) the testimony of the human relics, particularly that of 

 the pottery, be taken at its apparent paleontological value; if 



(2) the upper creek fill, whose accumulations demonstrably con- 

 tinued on until 19 13, be regarded as embracing all the human 

 relics, as seems quite consistent with the physical evidence; if 



(3) the critical extinct vertebrate fossils found in this upper creek 

 fill be regarded as derivatives from the lower creek fill; and if 



(4) the lower creek fill be regarded as contemporaneous with the 

 last living stages of the extinct vertebrates whose fossils it holds 

 as primary inclusions, as Dr. Sellards contends, the whole history 

 becomes consistent physically and paleontologically, and the gist 

 of its lesson is that the Pleistocene fauna lived longer in this 

 genial southern clime than it has been credited with in the more 

 northern latitudes, while the evidence of man's presence here falls 

 into harmony with the general tenor of other evidences which fail 

 to assign him an antiquity beyond the mid-Recent.
