There were several asteroid impacts at around the same time. For example, the Shiva impact off the west coast of India:

The Deccan Traps basaltic flows also happened at 'the same' time, in the same place:

It's not clear if the Shiva impact caused the volcanic activity, or it's just a remarkable coincidence.
- mikhailfranco 2y agoSo the Shiva 'crater' Structure may not be an impact, and the date for Shiva is taken directly from the Deccan Trap basalts, so not a remarkable coincidence, a fix.
- chiefalchemist 2y agoThis article I believe says otherwise. What's also great about this article is how it gives the rest of us a peek behind the curtain of science (and how emotional and unscientific it actually is). https://www.theatlantic.com/magazine/archive/2018/09/dinosaur-extinction-debate/565769/ https://www.theatlantic.com/magazine/archive/2018/09/dinosau...

- karunamurti 2y ago> Shiva impact caused the volcanic activity Heh, if I remember my Godology, it's on par with what Shiva do.
- southernplaces7 2y agoYou should have noted that the Shiva crater is far from a certainty or even a firmly founded theoretical impact. Only a minority believe it to be a crater at all.

Some nice maps and seismic sections in the paper: https://www.science.org/doi/10.1126/sciadv.abn3096 https://www.science.org/doi/10.1126/sciadv.abn3096 It seems possible that the Nadir Crater (9.5N 17W) is 'half way' between Shiva (2.5S? 55E) and Chicxulub (21.5N 90W) with (+12N +72W) step between them - making some wild assumptions about Shiva's location 65m years ago, when India was near the Reunion Hotspot: https://socratic.org/questions/where-was-india-65-million-years-ago https://socratic.org/questions/where-was-india-65-million-ye... So one asteroid splitting into 3+ pieces, of different sizes, but roughly the equal separation? Like Shoemaker-Levy 9? https://en.wikipedia.org/wiki/Comet_Shoemaker%E2%80%93Levy_9 https://en.wikipedia.org/wiki/Comet_Shoemaker%E2%80%93Levy_9
