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. In June 2021, paleontologist Melanie During submitted a manuscript to Nature that she suspected might create a minor scientific sensation. Mr. Frithiof was able to broker an agreement between Paleo Prospectors and DePalma. 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. Gizmodo covered the research at the time. According to The New Yorker, DePalma also sports some off-putting paleontology practices, like keeping his discovery secret for so long and limiting other scientists' access to the site. DePalma quickly began to suspect that he had stumbled upon a monumentally important and unique site not just "near" the K-Pg boundary, but a unique killing field that precisely captured the first minutes and hours after impact, when the K-Pg boundary was created, along with an unprecedented fossil record of creatures and plants that died on that day, as well as material directly from the impact itself, in circumstances that allowed exceptional preservation. When I saw [microtektites in their own impact craters], I knew this wasnt just any flood deposit. With this deposit, we can chart what happened the day the Cretaceous died. Your tax-deductible contribution plays a critical role in sustaining this effort. Dinosaurs have been dead for so long,'" DePalma told The Washington Post. 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). Other geologists say they can't shake a sense of suspicion about DePalma himself, who, along with his Ph.D. work, is also a curator at the Palm Beach Museum of Natural History in Wellington, Florida. But not everyone has fully embraced the find, perhaps in part because it was first announced to the world last week in an article in The New Yorker. Tanis is a site of paleontological interest in southwestern North Dakota, United States. Fossils from dinosaurs and other animals from thousands of years before the asteroid impact are very hard to come by, leading some to believe . DePalma gave the name Tanis to both the site and the river.

During the long process of discussing these options they decided to submit their paper, he says. 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. Another question about dinosaurs is what caused their extinction and there are many theories about that, too. They did a few years of digging, uncovering beautiful, fragile sh . Dont yet have access? Last month, During published a comment on PubPeer alleging that the data in DePalmas paper may be fabricated. More: Science Publisher Retracts 44 Papers for Being Utter Nonsense, We may earn a commission from links on this page. 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. Robert DEPALMA, Postgraduate Researcher | Cited by 253 | of The University of Manchester, Manchester | Read 18 publications | Contact Robert DEPALMA Help News from Science publish trustworthy, high-impact stories about research and the people who shape it. She also removed DePalma as an author from her own manuscript, then under review at Nature. Searching in the hills of North Dakota, palaeontologist Robert DePalma makes an incredible . Robert DePalma uncovers a preserved articulated body of a 65-million-year-old fish at Tanis. The day 66 million years ago when the reign of the dinosaurs ended and the rise of . If I were the editor, I would retract the paper unless [the raw data] were produced posthaste, he says. They've been presented at meetings in various ways with various associated extraordinary claims," a West Coast paleontologist said to The New Yorker. In turn, the fish remains revealed the season their lives endedergo, the precise timing of the devastating asteroid strike to the Yucatn Peninsula. Both papers studied 66-million-year-old paddlefish jawbones and sturgeon fin spines from Tanis. [1]:pg.11 Key findings were presented in two conference papers in October 2017. Robert A. DePalma, a paleontologist at the Palm Beach Museum of Natural History and a graduate student at the University of Kansas. [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. A fossil site in North Dakota records a stunningly detailed picture of the devastation minutes after an asteroid slammed into Earth about 66 million years ago, a group of paleontologists argue in a paper due out this week. The excavated pointbar and event deposits show that the point bar had been exposed to the air for a considerable time, with evidence of habitation and filled burrows, before an abrupt, turbulent, high energy event filled these burrows and laid down the deposits. DePalma also acknowledged that the manual transcription process resulted in some regrettable instances in which data points drifted from the correct values, but none of these examples changed the overall geometry of the plotted lines or affected their interpretation. McKinneys non-digital data set, he says, is viable for research work and remains within normal tolerances for usage.. The paleontologist Robert DePalma excavating a tangle of plant and animal fossils at the Tanis site in North Dakota. Melanie During suspects Robert DePalma wanted to claim credit for identifying the dinosaur-killing asteroid's season of impact and fabricated data in order to be able to publish a paper . It also proves that geology and paleontology is still a science of discovery, even in the 21 st Century." Using radiometric dating, stratigraphy, fossil pollen, index fossils, and a capping layer of iridium-rich clay, the research team laboriously determined in a previous study led by DePalma in 2019 that the Tanis site dated from precisely . His reputation suffered when, in 2015, he and his colleagues described a new genus of dinosaur named Dakotaraptor, found in a site close to Tanis. The extinction event caused by this impact began the Cenozoic, in which mammals - including humans - would eventually come to dominate life on Earth. If the team, led by Robert DePalma, a graduate student in paleontology at the University of Kansas in Lawrence, is correct, it has uncovered a record of apocalyptic destruction 3000 kilometers from Chicxulub. Was it a fierce volcanic eruption that toppled these creatures? Tanis is a site of paleontological interest in southwestern North Dakota, United States. May 9, 2022 at 7:00 a.m. EDT. 01/05/2021. 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. A fossil, after all, is only created under precise circumstances, with the dinosaur dying in a place that could preserve its remains in rock. DePalma characterizes their interactions differently. During described the findings in her 2018 masters thesis, a copy of which she shared with DePalma in February 2019. The event included waves with at least 10 meters run-up height (the vertical distance a wave travels after it reaches land). "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. The 2023 Complete Python Certification Bootcamp Bundle, What Is Carbon Capture? There is considerable detail for times greater than hundreds of thousands of years either side of the event, and for certain kinds of change on either side of the K-Pg boundary layer. Robert DePalma, a paleontologist at the Palm Beach Museum of Natural History and a graduate student at the University of Kansas, works at a fossil site in North Dakota. With Gizmodos Molly Taft | Techmodo. ^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. Fragile remains spanning the layers of debris show that the site was laid down in a single event over a short timespan. Robert A. DePalma1,2, David A. Burnham2,*, Larry D. Martin2,, Peter L. Larson 3 and Robert T. Bakker 4 1 Department of Vertebrate Paleontology, The Palm Beach Museum of Natural History, Fort Lauderdale, Florida; 2 University of Kansas Bio- though Robert DePalma's love of the dead and buried was anything but . The first documents a turtle fossil found at Tanis, killed by impalement by a tree branch, and found in the upper of two units of surge deposit, bracketed by ejecta. What we do know is that during the Jurassic period, great global upheaval occurred with increases in temperature, surging sea levels, and less humidity. But just one dinosaur bone is discussed in the PNAS studyand it is mentioned in a supplement document rather than in the paper itself. Today, the layer of debris, ash and soot resulting from the asteroid strike is preserved in the Earth's sediment. The first two were conference papers presented in January of that year. Melanie During suspects Robert DePalma wanted to claim credit for identifying the dinosaur-killing asteroids season of impact and fabricated data in order to be able to publish a paper before she did. It feels like a case of the dog ate my homework, and I dont think the relatives of Curtis McKinney deserve this, During told Gizmodo. This is misconduct, During wrote in an email to Gizmodo. A Triceratops or other ceratopsian ilium (hip bone) was found at the high water mark, in circumstances hinting that the dinosaur might speculatively have been a floating carcass and possibly alive at or just before impact,[5] but the paper describing such remains was still in progress as of 2019[6] the initial papers only include a photograph and its location within Tanis. Robert DePalma. Some scientists say this destroyed the dinosaurs; others believe they thrived during the period. He has mined a fossil site in North Dakota secretly for years. The paper, in the Proceedings of the National Academy of Sciences (PNAS), does not include all the scientific claims mentioned in The New Yorker story, including that numerous dinosaurs as well as fish were buried at the site. 03/30/2022. That same year, encouraged by a Dutch award for the thesis, she began to prepare a journal article. By looking through this window into the past, we can apply these lessons to today.
