The Day the Dinosaurs Died | The New Yorker
Has Robert DePalma found a snapshot of the KT extinction event?
From the article:

On August 5, 2013, I received an e-mail from a graduate student named Robert DePalma. I had never met DePalma, but we had corresponded on paleontological matters for years, ever since he had read a novel I’d written that centered on the discovery of a fossilized Tyrannosaurus rex killed by the KT impact. “I have made an incredible and unprecedented discovery,” he wrote me, from a truck stop in Bowman, North Dakota. “It is extremely confidential and only three others know of it at the moment, all of them close colleagues.” He went on, “It is far more unique and far rarer than any simple dinosaur discovery. I would prefer not outlining the details via e-mail, if possible.” He gave me his cell-phone number and a time to call.

I called, and he told me that he had discovered a site like the one I’d imagined in my novel, which contained, among other things, direct victims of the catastrophe. At first, I was skeptical. DePalma was a scientific nobody, a Ph.D. candidate at the University of Kansas, and he said that he had found the site with no institutional backing and no collaborators. I thought that he was likely exaggerating, or that he might even be crazy. (Paleontology has more than its share of unusual people.) But I was intrigued enough to get on a plane to North Dakota to see for myself.

Found: fossil 'mother lode' created by asteroid that wiped out dinosaurs | Science | The Guardian
2019-04-01, by Agence France Presse,

"(...) In a paper to be published on Monday, a team of paleontologists at the University of Kansas say they found a “mother lode of exquisitely preserved animal and fish fossils” in what is now North Dakota. (...)

At the fossil site – called Tanis in North Dakota’s Hell Creek Formation – the surge left “a tangled mass of freshwater fish, terrestrial vertebrates, trees, branches, logs, marine ammonites and other marine creatures”, according to Robert DePalma, the report’s lead author. (...)

“The sedimentation happened so quickly everything is preserved in three dimensions – they’re not crushed,” said co-author David Burnham. “It’s like an avalanche that collapses almost like a liquid, then sets like concrete. They were killed pretty suddenly because of the violence of that water. We have one fish that hit a tree and was broken in half.”

The fossils at Tanis include what were believed to be several newly identified fish species, and others that were “the best examples of their kind”, said DePalma, curator of the Palm Beach Museum of Natural History in Florida.

“We look at moment-by-moment records of one of the most notable impact events in Earth’s history. No other site has a record quite like that,” he said. (...)"
