Iridium in undersea crater confirms asteroid wiped out the dinosaurs Hamish Johnston, Physics World, February 24, 2021, https://physicsworld.com/a/iridium-in-undersea-crater-confirms-asteroid-wiped-out-the-dinosaurs/ Tha paper is: Goderis, S., Sato, H., Ferrière, L, et al. 2021, Globally distributed iridium layer preserved within the Chicxulub impact structure Science Advances 24 Feb 2021: Vol. 7, no. 9, eabe3647 https://advances.sciencemag.org/content/7/9/eabe3647 There are arguments that seismic waves from the Chicxulub impact did a superfrack job on the Deccan volcanoes and magnified their eruptions.
