Description
It is believed that the Zhamanshin crater is the site of the most recent meteorite impact event of the magnitude that could have produced a disruption comparable to that of a nuclear winter, but it was not sufficiently large enough to have caused a mass extinction.[2]
Preliminary papers in the late 1970s suggested either Elgygytgyn,[3] or Zhamanshin,[4] as the source of the Australasian strewnfield.
