were found beneath the fossihzed skeleton of a bison that 

 was embedded in deposits of unquestionable Pleistocene age. 

 Associated fossil fragments in this Texas deposit show a fauna 

 including mammoths, camels, and extinct horses. Remains of 

 human skeletons found in Florida have been said to be of PKocene 

 age, but this is not generally accepted. These Florida remains 

 are probably post-Pleistocene, although they may be at least

20,000 years old, by a conservative estimate. Despite the opinion 

 of many anthropologists that man was a comparatively recent 

 arrival upon this continent, it is, therefore, expected by others that 

 new finds will confirm the above evidence of his existence in Amer- 

 ica during the Pleistocene or Glacial Epoch when more than one 

 race flourished in Europe. Even though the American Indians 

 of North and South America did enter by way of Bering Straits in 

 comparatively recent times, they may have been preceded by 

 earlier races.
