Massive meteorite crater found in Western Australia thought to be 100 million years old, The Guardian Meteorite crater discovered while drilling for gold in outback WA estimated to be 100 million years old ABC Goldfields / By Jarrod Lucas, Australian Broadcasting Corporation. 100 million-year-old meteorite crater found in Western Australia, WION Web Team New Delhi, Delhi, India Sep 03, 2020 Notes: 1. At only 5 km in diameter, it is not "one of the largest meteorite craters discovered in the world" as the Guardian article states. 2. Technically speaking the reported structure, if valid, is an impact structure, not an impact crater as the articles state. Yours, Paul H.-
