A puzzle that makes me strongly doubt the common belief that all mass
extinctions are associated with impactors: If tektites are linked to large
impacts--and hence and extinctions--it is more than ironic that the
700,000+- year old  Australasian tektite event, the largest tektite strewn
field on this planet, has neither an impact crater  NOR a mass extinction
associated with it!  In fact, I believe "Java Man" was living at the time
and it certainly didn't wipe out humanity and a majority of the major animal
species alive today.
