The result would have been that the particular grassy tundra needed by Ice Age megafauna would have died before it could move south far enough to sustain the megafauna ecosystem.
A few pygmy mammoths survived until about 3000 years ago on arctic islands in the Russian far north.
The alignment of the Carolina Bays seems to point at an area a bit south and a bit west of Lake Superior.
IIRC.
Believe it or not, pigmy mammoths also survived quite late on Catalina Island off the California coast. The time period I’ve read was up to about 4,000 to 5,000 years ago. They were related to the Colombian mammoths who lived across Norh America and into Central America. People forget that not all mammoths were woolly!
Thank you, the most cogent theory of the death of all mega fauna presented, it wasn’t just the mammoths. I have never believed hunters were responsible or contributed in any way, more PC junk science. I personally stumbled upon a mammoth hunters knife and thumb scraper several years back while hunting. To hold such artifacts in ones own hands took me back to a time when my area was very much different, I could almost feel their past presence. Hunters are so politically non correct in this era, not so in many past cultures.
Now there I see a commercial possibility. Create herds of the little ones for their wool. People would pay a fortune for a mammoth-wool coat. I also suspect that people descended from ice-age European populations probably have a natural taste for mammoth meat. I for one, can't wait to try those steaks.
If in fact the mega-fauna were decimated by a major boloid strike in upper North America, then I see no logic to the argument that there time had come. There are areas isolated enough in the far north that they could be housed in.
