[8] Following suspicions of manipulating data, a complained was lodged against DePalma with the University of Manchester. Robert DePalma (right) and Walter Alvarez (left) at the Tanis site in North Dakota. A A. Paleontologist Robert DePalma has done it again. Please make a tax-deductible gift today. Even as a child, DePalma wondered what the Cretaceous was like. 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. The study of these creatures is limited to the fossils they left behind and those provide an incomplete picture. While DePalma corrected his claim, his reputation still took a hit. When we look at the preservation of the leg and the skin around the articulated bones, we're talking on the day of impact or right before. 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. Additional fossils, including this beautifully preserved fish tail, have been found at the Tanis site in North Dakota. On 2 December, according to an email forwarded to Science, the editor handling DePalmas paper at Scientific Reports formally responded to During and Ahlberg for the first time, During says. This is not a case of he said, she said. This is also not a case of stealing someones ideas. Tanis is a site of paleontological interest in southwestern North Dakota, United States. . Subscribe to News from Science for full access to breaking news and analysis on research and science policy. DePalma characterizes their interactions differently. The former Purdue President is now 76 years of age. "His line between commercial and academic work is not as clean as it is for other people," says one geologist who asked not to be named. In the early 1980s, the discovery of a clay layer rich in iridium, an element found in meteorites, at the very end of the rock record of the Cretaceous at sites around the world led researchers to link an asteroid to the End Cretaceous mass extinction. Those files were almost certainly backed up, and the lab must have some kind of record keeping process that says what was done when and by whom., Barbi is similarly unimpressed. Some recent examples include the 1964 Alaskan earthquake (seiches in Puerto Rico),[14] the 1950 Assam-Tibet earthquake (India/China) (seiches in England and Norway), the 2010 Chile earthquake (seiches in Louisiana). But it's not at the asteroid's crash site. Published May 11, 2022 6:09PM (EDT) The site, after all, does not conclusively prove that the asteroid's impact actually caused the dinosaurs' demise, reported Science. . He says he did so because the isotopic data had been supplied as a non-digital data set by a collaborator, archaeologist Curtis McKinney of Miami Dade College, who died in 2017. Help News from Science publish trustworthy, high-impact stories about research and the people who shape it. Based on the chemical isotope signatures and bone growth patterns found in fossilized fish collected at Tanis, a renowned fossil site in North Dakota, During had concluded the asteroid that ended the dinosaur era 65 million years ago struck Earth when it was spring in the Northern Hemisphere. The same day, Ahlberg tweeted that he and During submitted a complaint of potential research misconduct against DePalma and Phillip Manning, one of the papers co-authors, to the University of Manchester. In a 6 January letter to the journal editor handling his manuscript, which he forwarded to Science, DePalma acknowledged that the line graphs in his paper were plotted by hand instead of with graphing software, as is the norm in the field. "That's the first ever evidence of the interaction between life on the last day of the Cretaceous and the impact event," says team member Phillip Manning, a paleontologist at the University of Manchester in the United Kingdom. In my view, it was an intentional omission which leads me to question the credibility of data. Steve Brusatte, a paleontologist at the University of Edinburgh, says, There is a simple way for the DePalma team to address these concerns, and that is to publish the raw data output from their stable isotope analyses.. [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. 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. Traduzioni in contesto per "i paleontologi che" in italiano-inglese da Reverso Context: Ma i paleontologi che studiano dettagliatamente i denti fossilizzati di questi animali hanno sospettato che non erano quello semplice. 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]. Science and AAAS are working tirelessly to provide credible, evidence-based information on the latest scientific research and policy, with extensive free coverage of the pandemic. [1]:pg.11 Key findings were presented in two conference papers in October 2017. According to Science, DePalma was incorrect in 2015 when he believed he discovered a bone from a new type of dinosaur. [1]:p.8 The site formed part of a bend in an ancient river on the westward shore of the seaway,[1]:p.8192[4]:pp.5,6,23 and was flooded with great force by these waves, which carried sea, land, freshwater animals and plants, and other debris several miles inland. More: Science Publisher Retracts 44 Papers for Being Utter Nonsense, We may earn a commission from links on this page. Such Konservat-Lagersttten are rare because they require special depositional circumstances. DePalma purported that these animals died during the asteroid's impact since the glass's chemical makeup indicates an extraordinary explosion something similar to the detonation of 10 billion bombs. We absolutely would not, and have not ever, fabricated data and/or samples to fit this or another teams results, he wrote in an email to Science. It is certainly within the rights of the journal editors to request the source data, adds Mike Rossner, an independent scientist who investigates claims of biomedical image data manipulation. Dinosaurs continue to fascinate, even though they became extinct 65 million years ago. AAAS is a partner of HINARI, AGORA, OARE, CHORUS, CLOCKSS, CrossRef and COUNTER. Most of central North America had recently been a large shallow seaway, called the Western Interior Seaway (also known as the North American Sea or the Western Interior Sea), and parts were still submerged. When the dino-killing asteroid struck Earth, shock waves would have caused a massive water surge in the shallows, researchers say, depositing sedimentary layers that entombed plants and animals killed in the event. The x-rays revealed tiny bits of glass called spherulesremnants of the shower of molten rock that would have been thrown from the impact site and rained down around the world. They did a few years of digging, uncovering beautiful, fragile sh . DePalma did not respond to a Gizmodo request for comment, but he told Science, We absolutely would not, and have not ever, fabricated data and/or samples to fit this or another teams results., On December 9, a note was added to DePalmas paper on the Scientific Reports website. Searching in the hills of North Dakota, palaeontologist Robert DePalma makes an incredible . Help News from Science publish trustworthy, high-impact stories about research and the people who shape it. A study published by paleontologist Robert DePalma in December last year concluded that dinosaurs went extinct during the springtime. If they can provide the raw data, its just a sloppy paper. A fossil, after all, is only created under precise circumstances, with the dinosaur dying in a place that could preserve its remains in rock. Images: Top right, Robert DePalma and Peter Larson conduct field research in Tanis. 2021 (106) December (5) November (8) October (8 . The day 66 million years ago when the reign of the dinosaurs ended and the rise of . Science and AAAS are working tirelessly to provide credible, evidence-based information on the latest scientific research and policy, with extensive free coverage of the pandemic. [5] The original discoverers of the site (Rob Sula and Steve Nicklas), who worked the site for several years, recognized its scientific importance and offered it to DePalma as he had some previous experience with working on fish sites. During and Ahlberg, a member of the Royal Swedish Academy of Sciences, question whether they exist. [15][1]:p.8. [1]:p.8 Instead, the initial papers on Tanis conclude that much faster earthquake waves, the primary waves travelling through rock at about 5km/s (11,000mph),[1]:p.8 probably reached Hell Creek within six minutes, and quickly caused massive water surges known as seiches in the shallow waters close to Tanis. The paleontologist believed that this new information further supported the theory that an asteroid . The site lacked the fine sediment layers he was initially looking for. Others defend DePalma, like his co-author, Mark Richards, a geophysicist at the University of California, Berkeley. Others later pointed out that the reconstructed skeleton includes a bone that really belonged to a turtle; DePalma and his colleagues issued a correction. "Those few meters of rock record the wrath of the Chicxulub impact and the devastation it caused." But McKinneys former department chair, Pablo Sacasa, says he is not aware of McKinney ever collaborating with laboratories at other institutions. Their team successfully removed fossil field jackets that contained articulated sturgeons, paddlefish, and bowfins. But there were other inconsistencies at the excavation site the fossils they found seemed out of place, with some skeletons located in vertical positions. Tanis is on private land; DePalma holds the lease to the site and controls access to it. ^Note 2 If two earthquakes have moment magnitudes M1 and M2, then the energy released by the second earthquake is about 101.5 x (M2 M1) times as much at the first. By looking through this window into the past, we can apply these lessons to today. After The New Yorker published "The Day the Dinosaurs Died," which details the discovery of a fossil site in Hell's Creek, North Dakota, by Robert DePalma a Kansas State PhD student and paleontologist, debates and discussions across the country arose over the article. [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". [1]:p.8193 The original paper describes the river in technical detail:[1]:Fig.1 and p.9181-8193. It could be just one factor in a series of environmental events that led to their extinction. As detailed by Science, the isotopic data in DePalmas paper was collected by archaeologist Curtis McKinney, who died in 2017. DePalma submitted his own paper to Scientific Reports in late August 2021, with an entirely different team of authors, including his Ph.D. supervisor at the University of Manchester, Phillip Manning. In 2004, DePalma was studying a small site in the well-known Hell Creek Formation, containing numerous layers of thin sediment, creating a geological record of great detail.His advisor suggested seeking a similar site, closer to the K-Pg boundary layer. Still, when During submitted her manuscript to Nature on 22 June 2021, she listed DePalma as the studys second author. 03/30/2022. They presumably formed from droplets of molten rock launched into the atmosphere at the impact site, which cooled and solidified as they plummeted back to Earth. With the exception of some ectothermic species such as the ancestors of the modern leatherback sea turtle and crocodiles, no tetrapods weighing more than 25kg (55lb) survived. 2023 American Association for the Advancement of Science. It is truly a magnificent site surely one of the best sites ever found for telling just what happened on the day of the impact. . In fact, there are probably dinosaur types that still remain unidentified, reported Smithsonian Magazine. The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth. .mw-parser-output .citation{word-wrap:break-word}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}^Note 1 This section is drawn from the original 2019 paper[1] and its supplementary materials,[4] which describe the site in detail. . Paleontologist Robert DePalma, postgraduate researcher at University of Manchester UK and adjunct professor for the Florida Atlantic University Geosciences Department, gave a guest talk at NASA's Goddard Space Flight Center in Greenbelt, Maryland, on April 6. The Byte reports that the amber was found 2,000 miles away from the asteroid crater off the coast of Mexico believed to be . With this deposit, we can chart what happened the day the Cretaceous died. Mr. Frithiof was able to broker an agreement between Paleo Prospectors and DePalma. By Robert Sanders, Media relations | March 29, 2019. 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. Episode . Some scientists question Robert DePalma's methods. The 2023 Complete Python Certification Bootcamp Bundle, What Is Carbon Capture? 2023 American Association for the Advancement of Science. Paleontologist accused of faking data in dino-killing asteroid paper. Get more great content like this delivered right to you! Jan Smit first presented a paper describing the Tanis site, its association with the K-Pg boundary event and associated fossil discoveries, including the presence of glass spherules from the Chicxulub impact clustered in the gill rakers of acipenciform fishes and also found in amber. A field assistant, Rudy Pascucci, left, and the paleontologist Robert DePalma, right, at DePalma's dig site. Any water-borne waves would have arrived between 18 and 26 hours later,[1]:p.24 long after the microtektites had already fallen back to earth, and far too late to leave the geological record found at the site. Trapped in the debris is a jumbled mess of fossils, including freshwater sturgeon that apparently choked to death on glassy particles raining out of the sky from the fireball lofted by the impact. Other papers describing the site and its fossils are in progress. At his suggestion, she wrote a formal letter to Scientific Reports. DePalma has not made public the raw, machine-produced data underlying his analyses. The bottom line is that this case will just involve bluster and smoke-blowing until the authors produce a primary record of their lab work, adds John Eiler, a geochemist and isotope analysis expert at the California Institute of Technology. Now, a different group of researchers is accusing the former group of faking their data; the journal that published the research has added an editors note to the paper saying the data is under review. . In the early 1980s, the discovery of a clay layer rich in iridium, an element found in meteorites, at the very end of the rock record of the Cretaceous at sites around the world led researchers to link an asteroid to the End Cretaceous mass extinction. If I were the editor, I would retract the paper unless [the raw data] were produced posthaste, he says. Your tax-deductible contribution plays a critical role in sustaining this effort. Isaac Schultz. He has mined a fossil site in North Dakota secretly for years. This program was also aired as "Dinosaur Apocalypse: The Last Day" on PBS Nova starting 11 May 2022.[9][32]. Robert DePalma. Asked where McKinney conducted his isotopic analyses, DePalma did not provide an answer. The site was systematically excavated by Robert DePalma over several years beginning in 2012, working in near total secrecy. Raw machine data are seldom supplied to end users (myself included) who contract for isotope analyses from a lab that does them., Cochran says DePalma erred in not including these data and their origins in his original manuscript, but the bottom line is that I have no reason to distrust the basic data or in any way believe that it was fabricated., Eiler disputes this. DePalma's dinosaur study, published in Scientific Reports in December 2021, . They seem to have left the raw data out of the manuscript deliberately, he says. The lead author of that paper, and of the 2021 Scientific Reports paper, is Robert DePalma, a paleontologist who was the central character in a lengthy story published by The New Yorker a day . Robert DePalma made headlines again in 2021 with the discovery of a leg from a Thescelosaurus dinosaur at Tanis, reported The Washington Post. though Robert DePalma's love of the dead and buried was anything but . Today, the layer of debris, ash and soot resulting from the asteroid strike is preserved in the Earth's sediment. Robert DePalma is a paleontologist who holds the lease to the Tanis site and controls access to it.

In a recent article in The New Yorker, author Douglas Preston recounts his experience with paleontologist Robert DePalma, who uncovered some of the first evidence to settle these debates. Instead, much faster seismic waves from the magnitude 10 11.5 earthquakes[1]:p.8 probably reached the Hell Creek area as soon as ten minutes after the impact, creating seiche waves between 10100m (33328ft) high in the Western Interior Seaway. Several independent scientists consulted about the case by Science agreed the Scientific Reports paper contains suspicious irregularities, and most were surprised that the paperwhich they note contains typos, unresolved proofreaders notes, and several basic notation errorswas published in the first place. Until a few years ago, some researchers had suspected the last dinosaurs vanished thousands of years before the catastrophe. [31][18], A BBC documentary on Tanis, titled Dinosaurs: The Final Day, with Sir David Attenborough, was broadcast on 15 April 2022. During, whose paper was accepted by Nature shortly afterward and published in February, suspects that DePalma, eager to claim credit for the finding, wanted to scoop herand made up the data to stake his claim. They've been presented at meetings in various ways with various associated extraordinary claims," a West Coast paleontologist said to The New Yorker. But two months before Durings paper would be published, a paper came out in Scientific Reports reaching essentially the same conclusion, based on an entirely separate data set, Science reported. "I've been asked, 'Why should we care about this? paper] may be fabricated, created to fit an already known conclusion. (She also posted the statement on the OSF Preprints server today.). Robert DePalmashown here giving a talk at NASAs Goddard Space Flight Center in Aprilpublished a paper in December 2021 showing the asteroid that killed the dinosaurs struck Earth in the spring. This dinosaur, a giant reptilian, lived during the Early Cretaceous period in oceans. Scientists believe they have been given an extraordinary view of the last day of the dinosaurs after they discovered the fossil of an animal they believe . [8] The site continues to be explored. DePalma gave the name Tanis to both the site and the river. Robert DePalma, fdd 12 oktober 1981, r en amerikansk paleontolog och kurator . These tables are not the same as raw data produced by the mass spectrometer named in the papers methods section, but DePalma noted the datas credibility had been verified by two outside researchers, paleontologist Neil Landman at the American Museum of Natural History and geochemist Kirk Cochran at Stony Brook University. Petrified fish with glass spheres, called ejecta, were also at the site. The nerds travel to the final day of the dinosaurs reign with paleontologist Robert DePalma and the legendary Tanis Site. The site, dubbed "Tanis," first underwent excavation in 2012, with DePalma and his team digging along a section known as the Hell Creek Formation (via Boredom Therapy). [30] However, the journal later published a note in December 2022 stating that "the reliability of data presented in this manuscript [] currently in question" following claims that data in the paper was fabricated in order to scoop a later paper[18] published in Nature February 2022 (but submitted before the Scientific Reports paper was submitted), by a separate team, which also studied the fish skeletons found at Tanis, and also identified annual cyclical changes, and found that the impact had occurred in spring. They had breathed in early debris that fell into water, in the seconds or minutes before death. [5] The fish were not bottom feeders. The extinction event caused by this impact began the Cenozoic, in which mammals - including humans - would eventually come to dominate life on Earth. FAU's Robert DePalma, senior author and an adjunct professor in the Department of Geosciences, Charles E. Schmidt College of Science, and a doctoral student at the . The first two were conference papers presented in January of that year. A thin layer of bone cells on sturgeons fins thickens each spring and thins in the fall, providing a kind of seasonal metronome; the x-rays revealed these layers were just beginning to thicken when the animals met their end, pointing to a springtime impact. DePalma believed that the fossils found in Tanis, which sat on the KT layer, became collected there just after the asteroid struck the earth. After his team learned about Durings plan to submit a paper, DePalma says, one of his colleagues strongly advised During that the paper must at minimum acknowledge the teams earlier work and include DePalmas name as a co-author.
