icon Extinction

According to Discovery magazine, April 1999, the American Mastodon roamed here for about 4 million years until about 11,500 years ago. Another type, the Mammuthus primigenius, roamed around 400,000 years until 3,900 years ago. Both extinction times could be multiples of 3,600 years.

The heyday of the woolly mammoth was the Pleistocene Epoch, stretching from 1.8 million years ago to the end of the last ice age 11,000 years ago. Mammoths thrived particularly well in Siberia, where dry grasslands once stretched for hundreds of miles, supporting a vibrant ecosystem of mammoths, bison, and other jumbo herbivores. .. The mammoth fossils on Wrangel Island are the youngest that have ever been found. It was there, apparently, that mammoths made their last stand. They died out only 3,800 years ago.

Excerpt from a recent program that I am quoting:

It had always been thought that the mammoth died out about ten thousand years ago, with the end of the ice age, but the tusk appeared to be 7,000 years old. It was so unlikely, so Buttanyan tested five more tusks, but the new dates pointed to an even more remarkable conclusion. Hidden up here [Rangell Island] in the Arctic, the mammoth hadn't just survived the end of the ice age, it was walking these hills at the time of the Egyptian Pharaos, only 3500 years ago. This discovery has led to the re-examination of the complex chain of 'cause and effect' that made mammoths die out everywhere else, and in the process has revitalized the whole debate about how species might avoid extinction.

Well, about 3500 years ago the 12th planet passed the earth, maybe not causing a pole shift but certainly, I think, it caused some major volcanic activity, blackening the skies for at least a decade. Vegetation might have died off on the island, killing off the last of the remaining and already thinned out mammoths in the world on Rangell island. Yet another drama in earth's history. Do not worry, our earth's soap opera is continuing.
