The largest in the last one million years is the 14-kilometre (8.7 mi) Zhamanshin crater in Kazakhstan and has been described as being capable of producing a nuclear-like winter. [11] The source of the enormous Australasian strewnfield (c. 780 ka) is a currently undiscovered crater probably located in Southeast Asia. [12] [13]
The Decorah crater has been conjectured as being part of the Ordovician meteor event. [346] [better source needed] Several twin impacts have been proposed, such as the Rubielos de la Cérida and Azuara (30–40 Ma), [347] Cerro Jarau and Piratininga (c. 117 Ma), [73] and Warburton East and West (300–360 Ma).

As of April 2019, the database lists 190 confirmed impact sites. [1] Other lists are wider in scope by including more than just confirmed sites, such as probable, possible, suspected and rejected or discredited impact sites on their lists.
