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."

KIlled not murdered. Murder, I think suggests intent.

The article is interesting so thanks for posting it.
I wonder if there were multiple kill zones for this
'event.' Or perhaps I should about the kill zone
size. I'd wonder if may have been a complex event.
A grazing interaction of the planet with a rather large
cometary body. Some hitting Mexico and the rest
in a decaying orbit that then rains down over the
coming months. I suppose we need to look at
the climate proxies at the time for suggestions of
an event. Sudden warming going to cold in the
span of year? Perhaps ocean sediment would have
a grand change in plankton organisms?

Anyway the timing is suggestive on an event that
falls at the close of the Pleistocene and extinctions
were NOT confined to North American or Central
American but seem rather more evenly spread.

if I had a time machine,
I could cause all sorts of trouble ;-)
Then again maybe I do .........Trig
