Unconfirmed impact structures

Main article: List of possible impact structures on Earth

The following structures are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed. However, entries on the unconfirmed list could still have an impact origin disproven.

Name	State	Diameter (km)	Age	Coordinates
Bedout[3][4]	Indian Ocean, Western Australia	200	250 million	18°S 119°E
Darwin Crater[5]	Tasmania	1.2	800 thousand	42°19′S 145°40′E
Deniliquin multiple-ring feature[6]	Southeast Australia	520	445-444 million, Hirnantian mass extinction event[7]	35°32′0″S 144°58′0″E
Diamantina River ring feature[8][9]	Upper Diamantina River, Queensland	130	300 million	22.15°S 141.9°E / -22.15; 141.9 (?)
East Warburton Basin[10]	South Australia	200 [11]	about 300-360 million	27°0′S 140°5′E
West Warburton Basin[12]	South Australia	200 [11]	about 300-360 million
Gnargoo[13]	Carnarvon Basin, Western Australia	75	<300	24°48′24″S 115°13′29″E
