The scale claims to be labeled years before present, but all the numbers are negative. Negative years before present equals positive years AFTER present which is clearly wrong. I suggest it be re-labeled "years relative to present" to be least confusing. 108.233.124.132 ( talk) 01:29, 22 October 2019 (UTC) Twitter/CalRobert
Looking at Various Volcanic Traps ( sequential lava flows ), at the same time as Large Impact events, the two locations were probably antipodal. The Energy from the Large impact events would refract and reflect inside the Earth and come back to an anti-podal focal point that is located 180 degrees away from the Impact site in all directions. The refocusing of energy will severely fracture the Earth's surface at that point leading to extensive, and repeated lava flows. For example: The Deccan Traps was antipodal to the Chicxulub Impact site when the Impact site was 3 degrees north of the Equator, and the Deccan Traps site was 3 degrees south of the equator, both at 66.043 Ma. Both sites are now far north of the equator, as most of the continents are now north of the equator. A similar antipodal set up would be associated with the Wilkes Land Impact site, and the Siberian Traps at 252.17 Ma. The Impact near to the South Pole, and the Traps near to the North Pole.
This same concept can be applied to the other Impact-Traps extinction events. 63.225.17.34 ( talk) 21:14, 27 January 2020 (UTC)
Dear (63.225.17.34), I happened to be investigating this very topic a few years back and ran into this article. It may be of interest to you: https://www.princeton.edu/news/2011/10/19/impact-study-princeton-model-shows-fallout-giant-meteorite-strike#top -- Frunobulax ( talk) 00:15, 31 July 2021 (UTC)
Can "collapse of ozone layer" be added to "Probable causes" under Late Devonian extinction, per https://advances.sciencemag.org/content/6/22/eaba0768? —Biscuit-in-Chief :-) ( /tɔːk/ – /ˈkɒntɹɪbs/) 20:29, 4 June 2020 (UTC)
Oiyarbepsy has deleted the Deccan Traps as a possible cause of the extinction as "a tiny minority opinion and borderline fringe". This is true as a sole cause, but not as a contributory one. See for example [1] and [2]. Also, the source cited for impact in the article is a book putting forward a fringe theory by an astrophysicist that the impact was caused by dark matter, Dark Matter and the Dinosaurs. I suggest showing impact as the main cause with volcanism as a possible contributory one giving the two sources above as references. Dudley Miles ( talk) 22:40, 3 January 2021 (UTC)
