Bedout, off the northwestern coast of Australia, is a large depression in the ocean basin approximately 200 km across.
Some scientists speculate that Bedout might be the result of a large bolideimpact that occurred around 250 million years ago; a large impact event during that time frame could account for the Permian_Triassic extinction event. Sediment samples appear to match the date of the extinction event. Also, the shocked quartz patterns at the site appear to be consistent with bolide impacts; however, skeptics contend that the shape of the depression is inconsistent with bolide impacts; instead, the depression might be explained by other scenarios, such as an oddity in the earth's structure. In addition, iridium anomalies, a feature associated with massive bolide impacts, have not been found. Continuing research could yield more clues in the years to come.

Bedout or Bedout High, (IPA pronunciation: [bedʉː]) is about 25 km off the northwestern coast of Australia in the Roebuck basin.
Some scientists speculate that Bedout might be the result of a large bolide impact event that occurred around 250 million years ago; a large impact event during that time frame, incurring other factors, could account for the Permian-Triassic extinction event.
The Bedout impact crater is also associated in time with extreme volcanism and the break-up of Pangea.
