The Early Holocene Survival of Late Pleistocene Megafauna in the Americas

GeorgiaBeforePeople

Most Pleistocene species of North American megafauna stopped occurring in the fossil record about 12,000 calender years ago.  It is remarkable how consistently the latest terminal radiocarbon dates of Pleistocene megafauna cluster around this time boundary.  Specimens that date to younger than this boundary are always questioned and resubmitted for another round of radiocarbon dating till a more believable result is attained, or they are dismissed as “contaminated” samples.  One notable exception to this rule was the discovery that mammoths survived on the Pribiloff Islands located between Siberia and Alaska until about 4000 calender years ago.  (See:http://markgelbart.wordpress.com/2013/09/15/the-late-extinction-of-the-pribiloff-island-mammoths/).  Another accepted exception are some of the fossils of dwarf ground sloths found on Carribean islands.  They also date to just a few thousand years ago.  However, these late survival sites are considered special cases explained by the isolation of islands.  The consistent terminal radiocarbon dates on the mainland suggested to scientists…
