Taylor Mickal/NASA. November 5, 2015. Eighteen months before publication of the peer-reviewed PNAS paper in 2019[1] DePalma and his colleagues presented two conference papers on fossil finds at Tanis on 23 October 2017 at the annual meeting of the Geological Society of America. [8] Following suspicions of manipulating data, a complained was lodged against DePalma with the University of Manchester. [5] Secrecy about Tanis was maintained until disclosed by DePalma and co-author Jan Smit in two short summary papers presented in October 2017,[2][3] which remained the only public information before widespread media coverage of the full prepublication paper on 29 March 2019. Your tax-deductible contribution plays a critical role in sustaining this effort. Additional fossils, including this beautifully preserved fish tail, have been found at the Tanis site in North Dakota. Forum News Service, provided The paleontologist Robert DePalma excavating a tangle of plant and animal fossils at the Tanis site in North Dakota. If I were the editor, I would retract the paper unless [the raw data] were produced posthaste, he says. [15][1]:p.8. Today, the layer of debris, ash and soot resulting from the asteroid strike is preserved in the Earth's sediment. It can be divided into two layers, a bottom layer about 0.5m thick ("unit 1"), and a top layer about 0.8m thick (unit 2), capped by a 1 2cm layer of impactite tonstein that is indistinguishable from other dual layered KPg impact ejection materials found in Hells Creek, and finally a layer around 6cm thick of plant remains.

Manning confirms rumors that the study was initially submitted to a journal with a higher impact factor before it was accepted at PNAS. [1]:p.8193 The original paper describes the river in technical detail:[1]:Fig.1 and p.9181-8193. ", "Tanis exhibits a depositional scenario that was unusual in being highly conducive to exceptional (largely three dimensional) preservation of many articulated carcasses (Konservat-Lagersttte). The latter paper was published by a team led by Robert DePalma, Durings former collaborator and a paleontologist now at the University of Manchester. The site lacked the fine sediment layers he was initially looking for. The mud and sand are dotted with glassy spherulesmany caught in the gills of the fishisotopically dated to 65.8 million years ago. . Of his discovery, DePalma said, "It's like finding the Holy Grail clutched in the . In the BBC documentary, Robert DePalma, a relative of film director Brian De Palma, can be seen sporting an Indiana Jones-style fedora and tan shirt. [3] DePalma then presented a paper describing excavation of a burrow created by a small mammal that had been made "immediately following the K-Pg impact" at Tanis. [5] Co-author Professor Phillip Manning, a specialist in fossil soft tissues,[19] described DePalma's working techniques at Tanis as "meticulous" and "borderline archaeological in his excavation approach". This directly applies to today. And, if they are not forthcoming, there are numerous precedents for the retraction of scholarly articles on that basis alone.. Michael Price is associatenews editor for Science, primarily covering anthropology, archaeology, and human evolution. "I'm suspicious of the findings. Miami Dade does not have an operational mass spectrometer, suggesting McKinney would have had to perform the isotope analyses underlying the paper at another facility. However, because it is rare in any case for animals and plants to be fossilized, the fossil record leaves some major questions unanswered. This is not a case of he said, she said. This is also not a case of stealing someones ideas. Bob was born in Newark, NJ on December 26, 1948 to the late James and Rose DePalma. By Robert Sanders, Media relations | March 29, 2019. We may earn a commission from links on this page. When I saw [microtektites in their own impact craters], I knew this wasnt just any flood deposit. The skull of the scarred Edmontosaurus also showed signs of trauma, and from the size and shape of the marks on the bone, Rothschild and fellow co-author Robert DePalma, a paleontologist at the . "I hope this is all legit I'm just not 100% convinced yet," said Thomas Tobin, a geologist at the University of Alabama in Tuscaloosa. Robert Depalma, paleontologist, describes the meteor impact 66 million years ago that generated a tsunami-like wave in an inland sea that killed and buried f. "That some competitors have cast Robert in a negative light is unfortunate and unfair," Richards told Science. Bde hans far och hans farfars bror var kirurger i Florida. A bad day for dinosaurs was the subject of an engaging hour-and-a-half for both paleontologists and NASA researchers. UW News staff. From the size of the deposits beneath the flood debris, the Tanis River was a "deep and large" river with a point bar that was towards the larger size found in Hell's Creek, suggesting a river tens or hundreds of meters wide. His advisor suggested seeking a similar site, closer to the K-Pg boundary layer. "After a while, we decided it wasn't a good route to go down," he says. If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. In December 2021, DePalma and his colleagues published an important paper . This impact, which struck the Gulf of Mexico 66.043 million years ago, wiped out all non-avian dinosaurs and many other species (the so-called "K-Pg" or "K-T" extinction). [5] The fish were not bottom feeders. A meteor impact 66 million years ago generated a tsunami-like wave in an inland sea that killed and buried fish, mammals, insects and a dinosaur, the first victims of Earth's most recent mass extinction event. Part of the phenomenally fossil-rich Hell Creek Formation, Tanis sat on the shore of the ancient Western Interior Seaway some 65 million years ago. Tanis is a significant site because it appears to record the events from the first minutes until a few hours after the impact of the giant Chicxulub asteroid in extreme detail. A researcher claims that Robert DePalma published a faulty study in order to get ahead of her own work on the Tanis fossil site. Tanis is on private land; DePalma holds the lease to the site and controls access to it. The deathbed created within an hour of the impact has been excavated at an unprecedented fossil site in North Dakota. Recognizing the unique nature of the site, Nicklas and Sula brought in Robert DePalma, a University of Kansas graduate student, to perform additional excavations. By Nicole Karlis Senior Writer. In June 2021, paleontologist Melanie During submitted a . [1]:p.8192 The river flowed Eastward (other than impact driven waves),[1]:p.8192 with inland being to the West; Tanis itself was therefore in an ancient river valley close to the Westward shore of the Interior Seaway. "I just hope this hasn't been oversensationalized.". Everything he found had been covered so quickly that details were exceptionally well preserved, and the fossils as a whole formed a very unusual collection fish fins and complete fish, tree trunks with amber, fossils in upright rather than squashed flat positions, hundreds or thousands of cartilaginous fully articulated freshwater paddlefish, sturgeon and even saltwater mosasaurs which had ended up on the same mudbank miles inland (only about four fossilized fish were previously known from the entire Hell Creek formation), fragile body parts such as complete and intact tails, ripped from the seafish's bodies and preserved inland in a manner that suggested they were covered almost immediately after death, and everywhere millions of tiny spheres of glassy material known as microtektites, the result of tiny splatters of molten material reaching the ground. When DePalmas paper was published just over 3 months later, During says she soon noticed irregularities in the figures, and she was concerned the authors had not published their raw data. This further evidences the violent nature of the event. Nicklas also indicates that "in 2012 we decided to try to find an academic paleontologist who had the necessary interest, time, and the ability to excavate the site A good friend of ours, Ronnie Frithiof, recommended Robert DePalma. The paleontologist believed that this new information further supported the theory that an asteroid killed the dinosaurs along with 75 percent of the animals and plants on Earth 66 million year . Even as a child, DePalma wondered what the Cretaceous was like. Proposed by Luis and Walter Alvarez, it is now widely accepted that the extinction was caused by a huge asteroid or bolide that impacted Earth in the shallow seas of the Gulf of Mexico, leaving behind the Chicxulub crater. [10][11] The impactor tore through the earth's crust, creating huge earthquakes, giant waves, and a crater 180 kilometers (112mi) wide, and blasted aloft trillions of tons of dust, debris, and climate-changing sulfates from the gypsum seabed, and it may have created firestorms worldwide.

"Outcrops like [this] are the reasons many of us are drawn to geology," says David Kring, a geologist at the Lunar and Planetary Institute in Houston, Texas, who wasn't a member of the research team. He has mined a fossil site in North Dakota secretly for years. The paleontologist believed that this new information further supported the theory that an asteroid . The plotted line graphs and figures in DePalmas paper contain numerous irregularities, During and Ahlberg claimincluding missing and duplicated data points and nonsensical error barssuggesting they were manually constructed, rather than produced by data analysis software. The death scene from within an hour of the impact has been excavated at an unprecedented . Tanis is the only known site in the Hell Creek Formation where such conditions were met, [so] the deposit attests to the exceptional nature of the [Event]. There was no advanced decay. If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. (Courtesy of Robert DePalma) You and your team have made some extraordinary finds, including an exquisitely preserved leg of a dinosaur that you believed died on the very day of the asteroid impact. High-resolution x-rays revealed this paddlefish fossil from Tanis, a site in North Dakota, contained bits of glassy debris deposited shortly after the dinosaur-killing asteroid impact. Robert DePalma: We know there would have been a tremendous air blast from the impact and probably a loud roaring noise accompanied with that similar to standing next to a 747 jet on the runway.

Asked where McKinney conducted his isotopic analyses, DePalma did not provide an answer. The chief editor of Scientific Reports, Rafal Marszalek, says the journal is aware of concerns with the paper and is looking into them.
