FOSSIL HUMAN REMAINS AT VERO, FLORIDA 39 



endured transportation before fossilization. But if the interpre- 

 tation of the history of the region be as outlined above, it would 

 not seem unreasonable to suppose (in case it be definitely estab- 

 lished that these species have been extinct in the region since the 

 close of the Pleistocene) that the turtle carapace and the wolf 

 skull, and other similar parts, had been subjected to a minimum of 

 transportation wear because originally buried in the upland forma- 

 tion close to the spot where they were found, and that they were 

 carried into the channel fill by the caving of the river bank, or some 

 similar operation involving little wear. In no case was the trans- 

 portation great. The other bones found in No. 2 and No. 3, in the 

 opinion of the writer, give as much evidence of wear and polishing 

 as would be expected of bones that were washed only short dis- 

 tances (from the upland bog to the places in the channel where 

 they were found) by the flood stages of the creek. 



Formation No. 3, therefore, seems to the writer to be very 

 recent geologically, as it is the flood-plain alluvium of the present 

 Van Valkenburg's Creek. The age of formation No. 2 can be 

 determined less positively. It is simply older than No. 3 and 

 younger than the Pleistocene bog deposits that lie west of the spill- 

 way, but it is the opinion of the writer that it is much nearer in 

 age to No. 3 than it is to the Pleistocene bog accumulation and 

 associated deposits which originally housed the old mammalian 

 bones.
