- A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact – which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago – in a shallow ocean region https://www.eurekalert.org/news-releases/972709 11 comments space

- Did dark matter kill the dinosaurs? The Solar System's periodic passage through a 'dark disk' on the galactic plane could trigger comet bombardments that would cause mass extinctions. http://www.nature.com/news/did-dark-matter-kill-the-dinosaurs-1.14839 11 comments space
- Fossilized seashells show signs of global warming, ocean acidification before dinosaur extinction. The researchers said that understanding how the Earth responded to past extreme warming and CO2 input can help us prepare for how the planet will respond to current, human-caused climate change. https://news.northwestern.edu/stories/2019/12/earth-was-stressed-before-dinosaur-extinction/&fj=1 39 comments science
- The dinosaurs went extinct due to environmental upheaval caused by a meteorite impact on the Earth 66 million years ago. New study shows that the key expansion of dinosaurs was also triggered by a mass extinction, one that happened 232 million years ago. http://www.bristol.ac.uk/news/2018/april/dinosaurs-ended-and-originated-with-a-bang-.html 6 comments science
- Rocks at asteroid impact crater off the Yucatan Peninsula record the first day of dinosaur extinction. New study confirms the asteroid impact set wildfires, triggered tsunamis and blasted so much sulfur into atmosphere that it blocked the Sun, causing global cooling, ultimately dooming dinosaurs. https://www.nsf.gov/discoveries/disc_summ.jsp?cntn_id=299284&org=nsf&from=news 96 comments science
- Scientists are still debating just how much of a role volcanism may have played in the K–Pg extinction event. Now, a machine-learning computer model has weighed in, finding that the CO2 and SO2 gas required to cause the extinction of the dinosaurs is consistent with the output of the Deccan Traps https://www.wired.com/story/what-killed-the-dinosaurs/ 30 comments science
- At the end of the Permian period 252m years ago, rapid global warming caused the largest extinction event in the Earth’s history known as the “great dying”. It wiped out the vast majority of marine and terrestrial animals on the planet, eclipsing even the extinction of the dinosaurs 65m years ago. https://www.theguardian.com/environment/2018/dec/06/global-warming-extinction-report-the-great-dying 6 comments science
- Asteroid dust found at Chicxulub Crater confirms the cause of dinosaurs’ extinction 66 million years ago.“We are now at the level of coincidence that geologically doesn’t happen without causation,” said the study's co-author Sean Gulick. https://astronomy.com/news/2021/03/asteroid-dust-found-at-chicxulub-crater-confirms-cause-of-dinosaurs-extinction 60 comments science
