Tar Pits Bring Researchers Together
Something happened about 11–13,000 years ago that drove most large animals in the Americas extinct, dooming the mammoth, mastodon, and saber-toothed cat, among many others. The megafauna catastrophe seen in the Americas also unfolded in other parts of the world, apparently staggered by thousands of years. Scientists have proposed theories about the causes of this Late Pleistocene extinction event, assigning varied degrees of responsibility to climate change and human activity. Reaching scientific consensus around the solution to this whodunnit requires more data about who died when.
