It's interesting that the video says the "mysterious" disappearance of the
woolly mammoths.  This brings to mind the mysterious disappearance of
Australia's megafauna—thought to be caused by the early Aboriginals
effectively changing the ecosystem over eons, as there was an overlap
of 25,000 years of the megafauna population and the Aboriginal population.

Life and death in tropical Australia, 40,000 years ago.

Bit of a fun video: time team digging in a rubbish tip in Oxford to find woolly mammoth tusks/bones. But some discussion relating environment to critters and geologic activity after critters have died, how to interpret to find bones. One of the better (earlier) Time Team episodes.
