The day the dinosaurs died

Interesting article in The New Yorker Magazine

https://www.newyorker.com/magazine/2...dinosaurs-died

An article about the discovery of a site containing fossils that almost certainly were directly killed by the Chicxulub impact. The site is also peppered with tektites and micro impact craters (similar to fossil ones seen from hailstones).

A long long time ago
I cant remember when
Terrible lizards would make each other smile
And I knew If I had my chance
I'd blow away that comet with my lance
and they'd be happy for a while

But the Cretaceous event made me shiver
with all the deaths that it delivered

The day the dinosaurs died.....

Maybe. I recognize the name. There is some controversy surrounding it. But if true it really is astonishing.

And the paper is out

Significance
The Chicxulub impact played a crucial role in the Cretaceous–Paleogene extinction. However the earliest postimpact effects, critical to fully decode the profound influence on Earth’s biota, are poorly understood due to a lack of high-temporal-resolution contemporaneous deposits. The Tanis site, which preserves a rapidly deposited, ejecta-bearing bed in the Hell Creek Formation, helps to resolve that long-standing deficit. Emplaced immediately (minutes to hours) after impact, Tanis provides a postimpact “snapshot,” including ejecta accretion and faunal mass death, advancing our understanding of the immediate effects of the Chicxulub impact. Moreover, we demonstrate that the depositional event, calculated to have coincided with the arrival of seismic waves from Chicxulub, likely resulted from a seismically coupled local seiche.

Abstract
The most immediate effects of the terminal-Cretaceous Chicxulub impact, essential to understanding the global-scale environmental and biotic collapses that mark the Cretaceous–Paleogene extinction, are poorly resolved despite extensive previous work. Here, we help to resolve this by describing a rapidly emplaced, high-energy onshore surge deposit from the terrestrial Hell Creek Formation in Montana. Associated ejecta and a cap of iridium-rich impactite reveal that its emplacement coincided with the Chicxulub event. Acipenseriform fish, densely packed in the deposit, contain ejecta spherules in their gills and were buried by an inland-directed surge that inundated a deeply incised river channel before accretion of the fine-grained impactite. Although this deposit displays all of the physical characteristics of a tsunami runup, the timing (<1 hour postimpact) is instead consistent with the arrival of strong seismic waves from the magnitude Mw ∼10 to 11 earthquake generated by the Chicxulub impact, identifying a seismically coupled seiche inundation as the likely cause. Our findings present high-resolution chronology of the immediate aftereffects of the Chicxulub impact event in the Western Interior, and report an impact-triggered onshore mix of marine and terrestrial sedimentation—potentially a significant advancement for eventually resolving both the complex dynamics of debris ejection and the full nature and extent of biotic disruptions that took place in the first moments postimpact.

Article in National Geographic online with good detail referencing the paper:

https://www.nationalgeographic.com/s...us-extinction/

Concerns from other scientists include the fact that the New Yorker article contains much more detail, such as claims about dinosaur fossil finds, that are not in the paper.

The only inconsistency I fail to understand is how they can claim marine species were washed into the freshwater valley, yet in another part of the article it says the timing was off.

Millions of years ago, but they can set the timing of the Tsunami in Montana to one hour after impact at Chixtalatamimab ??? ( or did I confuse the crater with the latest cancer chemo?)

99.9999% of all life on Earth died? I find that hard to believe given the rest of the data I've seen. I don't know what his source is for that. And there's some weird stuff in the article, like calling a mushroom "signature" of nuclear explosions, which is pretty silly but typical of media reporting about nuclear weapons.

The spherules in the gills apparently chemically match the type ejected by the Chicxulub impact, which are found all over the place. So that places it soon after the impact. Then I think they did a quick calculation about how quickly a shockwave and resultant tidal surge would take.

So philkensebben, please tell the court what exactly happened when you arrived at the levee, just after midnight, after you parked your Chevy? And what was your reaction when you realized that the bunch of good ol' boys drinking whiskey 'n rye that night whom you normally party with were not a bunch of good ol' boys at all, but were, in fact and according to your own testimony, " a bunch of drunken ******* dinosaurs"?!! That enraged you, didn't it? And that's when you decided that they had to be silenced forever?!!!

BBC Inside Science podcast interview with the Manchester author of the PNAS paper

https://open.spotify.com/episode/31fQ8Mzv1DjDHrfoD8Wvfo

well worth a listen, explaining how they chose what to include in the first paper.
