Evidence shows Ice Age animals were blasted with space material

Various meteorite fragments - Image 1It appears that the sky fell long before Chicken Little's time - during the Ice Age, to be exact. According to Richard Firestone, Allen West, and their fellow scientists from Lawrence Berkeley National Laboratory, ancient mammoth and bison tusks dating some 35,000 years old indicated that the beasts of the time were peppered with meteorite fragments.


According to Firestone and West, perforations, surface rings and embedded fragments in the mammoth and bison tusks remains all pointed to a blast that came from a single direction. Furthermore, the atomic structure of the fragments suggested a source that hadn't originated on Earth.

Unfortunately, the evidence that Firestone and West have discovered doesn't explain everything,  especially since bisons and mammoths were widely separated geographically at the hypothesized time of the impact. Nevertheless, Firestone and West are still attempting to understand the exact relationship between the meteorite impacts and the extinction of the ice age animals.
