'''Zhamanshin''' is a [[meteorite]] [[impact crater|crater]] in [[Kazakhstan]].

It is 14 [[kilometre|km]] in [[diameter]] and the age is estimated to be 900,000 ± 100,000 years ([[Pleistocene]]). The crater is exposed at the surface.<ref>{{cite Earth Impact DB | name = Zhamanshin| accessdate = 2009-08-20}}</ref>

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]].<ref>[http://www.unb.ca/passc/ImpactDatabase/essay.html Essay "Impact Cratering on Earth"], based on: R.A.F. Grieve, 1990, Impact cratering on the Earth, Scientific American, v. 262, 66-73.</ref>
