The Evidence for the Younger Dryer Period

The younger drier associated with it is a megafornal extinction like half of the megafornals on the planet when extinct there's a genetic bottleneck of the human species so we had a huge bottleneck. You have an incredible rise in sea levels around that period just after the younger drier and you have a tremendous climate catastrophe where the climate swings rapidly all over the planet. If there was anything around at that period particularly in America's it's gone like it would have been wiped out.
