Zhamanshin is a meteorite crater in Kazakhstan.
It is 14 km in diameter and the age is estimated to be 900,000 ± 100,000 years (Pleistocene). The crater is exposed at the surface.[1]
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 nuclear winter, but it was not sufficiently large to have caused a mass extinction.[2]
