 FACT: The cave drawings featured a woolly rhinoceros which lived in  Eurasia. None have been found in North America. They lived during  the Pleistocene epoch (1,808,000 to 11,550 years before present) and  are known mainly through cave drawings. Recent carbon dating has  shown that populations may have survived as recently as 8000 B.C. in  Western Siberia. A nearly complete specimen was also found in a tar  pit in Starunia, Poland. The oldest known cave paintings are  approximately 40,000 years old.
