So this theory is seriously suggesting that a comet/asteroid impact took at least 10,000 years to kill off a huge proportion of the dinosaurs? What, was death caught in traffic or something? LeapUK (talk) 21:22, 5 April 2016 (UTC)
Says: The duration of event was less than 10 ky, and the time span is too short to be explained by Deccan volcanism.Geogene (talk) 21:24, 5 April 2016 (UTC)
These species took thousands of years to die though. To link that to one event is truly bizarre; like blaming the fall of the British Empire on the Ice-Age. LeapUK (talk) 06:16, 6 April 2016 (UTC)
Only to the scientifically ignorant and/or the tin-foil hat crowd. Sorry. 22.214.171.124 (talk) 02:13, 5 November 2016 (UTC)
I have just modified one external link on Cretaceous–Paleogene extinction event. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
"Now, a paper just published in Scientific Reports has named another possible conspirator: crude oil. According to Kunio Kaiho and his colleagues at Tohoku University, in Sendai, Japan, the sudden ignition of underground oil at the Yucatán impact site could have jetted into the upper atmosphere a mass of fine black carbon, also known as soot. Human-made black carbon, the bane of Beijing, remains in the lower atmosphere for only a matter of days before falling back to the surface, where it warms the planet by absorbing heat. But black carbon injected into the stratosphere would have the opposite effect, acting as a long-lived sunshade that could abruptly cool Earth and inhibit photosynthesis over a period of years. Kaiho’s team suggests that the asteroid may have sent up as much as three billion tons of soot, hundreds of times more than the world’s industries release each year. Petroleum—the ectoplasm of ancient organisms, our shameful Anthropocene addiction—may have come back to haunt the dinosaurs, too." -- Darkness Falls on the Dinosaurs, By Marcia Bjornerud , New Yorker Elements, July 14, 2016
To be considered for our article, if the idea is well-received in the field. It sounds reasonable.... aside from the purple prose. --Pete Tillman (talk) 15:16, 6 August 2016 (UTC)
Here's the full text version of the paper, for anyone interested. Mikenorton (talk) 16:05, 6 August 2016 (UTC)
The event is almost always called the Cretaceous–Tertiary extinction event. Geoffrey.landis (talk) 01:38, 4 October 2016 (UTC)
The early part of the Tertiary is now officially called the Paleogene. Older scientific texts did refer to "Cretaceous-Tertiary" but this would be regarded as obsolete/incorrect if it were to be used now. GeoWriter (talk) 12:19, 21 November 2016 (UTC)
