Mammoths, sabre-tooths MURDERED by second giant space boulder

"First the dinos, then the mastodons ... then ..."

"A 16-strong team of international boffins have
added more evidence for the controversial theory
that a gigantic asteroid smashed into the Earth
12,900 years ago and wiped out a range of furry
mammals, including the mammoths.

The researchers found an ancient layer of thin,
dark sediment buried at the bottom of Lake
Cuitzeo in central Mexico that contains nano
diamonds, impact spherules and other exotic
materials that are only found after a cosmic
impact."
