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. He is survived by his loving wife,. Some scientists cite the KT layer a 66-million-year-old section of earth present through most of the world, with a high iridium level as proof that this is so. How to Know If the Heat Is Making You Sick. 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 . The formation is named for early studies at Hell Creek, located near Jordan, Montana, and it was designated as a National Natural Landmark in 1966. Based on the . Ritchie Hall | Earth, Energy & Environment Center 1414 Naismith Drive, Room 254 Lawrence, KS 66045 geology@ku.edu 785-864-4974 Science journalism's obligation to truth. If I were the editor, I would retract the paper unless [the raw data] were produced posthaste, he says. This means that the skeletons located there are older than the asteroid that hit the earth, suggesting that some other event, like widespread volcanic eruptions or even climate change, did the dinosaurs in even before the asteroid appeared. Robert DePalma, fdd 12 oktober 1981, r en amerikansk paleontolog och kurator . The death scene from within an hour of the impact has been excavated at an unprecedented . A researcher claims that Robert DePalma published a faulty study in order to get ahead of her own work on the Tanis fossil site. 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 . Some scientists question Robert DePalma's methods. 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. [citation needed], At the time of the Chicxulub impact, the present-day North American continent was still forming. Tanis is a site of paleontological interest in southwestern North Dakota, United States. This is not a case of he said, she said. This is also not a case of stealing someones ideas.

Asked where McKinney conducted his isotopic analyses, DePalma did not provide an answer. 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 . 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.. Both papers studied 66-million-year-old paddlefish jawbones and sturgeon fin spines from Tanis. 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. Raising the Bar: Chocolate's History, Art, and Taste With Sophia Contreras Rea 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. Although they stopped short of saying the irregularities clearly point to fraud, mostbut not allsaid they are so concerning that DePalmas team must come up with the raw data behind its analyses if team members want to clear themselves. Other papers describing the site and its fossils are in progress. . [1]:figure S29 pg.53 In 2022, a partial mummified Thescelosaurus was unearthed here with its skin still intact.[7]. Geologists have theorized that the impact, near what is now the town of Chicxulub on Mexico's Yucatn Peninsula, played a role in the mass extinction at the end of the Cretaceous period, when all the dinosaurs (except birds) and much other life on Earth vanished. Last month, During published a comment on PubPeer alleging that the data in DePalmas paper may be fabricated. Your tax-deductible contribution plays a critical role in sustaining this effort. Han vxte upp i Boca Raton i Florida. 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. though Robert DePalma's love of the dead and buried was anything but . No part of Durings paper had any bearing on the content of our study, DePalma says. "That some competitors have cast Robert in a negative light is unfortunate and unfair," Richards told Science. [18], DePalma began excavating systematically in 2012[1]:11 and quickly found the site to contain very unusual and promising features. posted a statement on the journal feedback website PubPeer, a document containing what he says are McKinneys data, Earliest evidence of horseback riding found in eastern cowboys, Funding woes force 500 Women Scientists to scale back operations, Lawmakers offer contrasting views on how to compete with China in science, U.K. scientists hope to regain access to EU grants after Northern Ireland deal, Astronomers stumble in diplomatic push to protect the night sky, Satellites spoiling more and more Hubble images, Pablo Neruda was poisoned to death, a new forensic report suggests, Europes well-preserved bog bodies surrender their secrets, Teens leukemia goes into remission after experimental gene-editing therapy, Paleontologist accused of fraud in paper on dino-killing asteroid, Scientist-Consultants Accuse OSI of Missing the Pattern, Journal will not retract influential paper by botanist accused of plagiarism and fraud.

Her former collaborator Robert DePalma, whom she had listed as second author on the study, published a paper of his own in Scientific Reports reaching essentially the same conclusion, based on an entirely separate data set. . The site, after all, does not conclusively prove that the asteroid's impact actually caused the dinosaurs' demise, reported Science. [13], The formation contains a series of fresh and brackish-water clays, mudstones, and sandstones deposited during the Maastrichtian and Danian (respectively, the end of the Cretaceous and the beginning of the Paleogene periods) by fluvial activity in fluctuating river channels and deltas and very occasional peaty swamp deposits along the low-lying eastern continental margin fronting the late Cretaceous Western Interior Seaway. Top left, a shocked mineral from Tanis. .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. Subscribe to News from Science for full access to breaking news and analysis on research and science policy. [26][27][28][29] A paper published in Scientific Reports in December 2021 suggested that the impact took place in the Spring or Early Summer, based on the cyclical isotope curves found in acipensieriform fish bones at the site, and other evidence. 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. 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. The day 66 million years ago when the reign of the dinosaurs ended and the rise of . 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. Appropriate editorial action will be taken once this matter is resolved.. Robert has been an Adjunct Professor in the Geosciences . 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. . But During, a Ph.D. candidate at Uppsala University (UU), received a shock of her own in December 2021, while her paper was still under review. In December 2021, a team of paleontologists published data . However, two independent scientists who reviewed the data behind the paper shortly after its publication say they were satisfied with its authenticity and have no reason to distrust it. Since 2013, Sackler has resided at a private property on the outskirts of Austin, Texas. However, because it is rare in any case for animals and plants to be fossilized, the fossil record leaves some major questions unanswered. The three-metre problem encompasses that . 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. 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. "The thing we can do is determine the likelihood that it died the day the meteor struck. No fossil beds were yet known that could clearly show the details that might resolve these questions. Bde hans far och hans farfars bror var kirurger i Florida. The latter paper was published by a team led by Robert DePalma, Durings former collaborator and a paleontologist now at the University of Manchester. Their team successfully removed fossil field jackets that contained articulated sturgeons, paddlefish, and bowfins. With this deposit, we can chart what happened the day the Cretaceous died. 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. There was no advanced decay. When one paleontologist began excavating a dig site in the mountains of North Dakota, he soon discovered new dinosaur evidence that may change history. 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. This dinosaur, a giant reptilian, lived during the Early Cretaceous period in oceans. 2 / 4: Robert A. DePalma, a paleontologist at the Palm Beach Museum of Natural History and a graduate student at the University of Kansas. 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. 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. A newly discovered winged raptor may have belonged to a lineage of dinosaurs that grew large after . What we do know is that during the Jurassic period, great global upheaval occurred with increases in temperature, surging sea levels, and less humidity. He has mined a fossil site in North Dakota secretly for . With David Attenborough, Robert DePalma, Phillip Manning. View Obituary & Service Information With Gizmodos Molly Taft | Techmodo. Manning confirms rumors that the study was initially submitted to a journal with a higher impact factor before it was accepted at PNAS. And, if they are not forthcoming, there are numerous precedents for the retraction of scholarly articles on that basis alone.. 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. Fish were swept up in mud and sand in the aftermath of a great wave sparked by the Chicxulub impact, paleontologists say. Paleontologist Jack Horner, who had to revise his theory that the T. rex was solely a scavenger based on a previous finding from DePalma, told the New Yorker he didn't remember who DePalma was . Last modified on Fri 8 Apr 2022 11.20 EDT. Please make a tax-deductible gift today. 03/30/2022. This directly applies to today. [12] It marked the end of the Cretaceous period and the Mesozoic Era, opening the Cenozoic Era that continues today. But McKinneys former department chair, Pablo Sacasa, says he is not aware of McKinney ever collaborating with laboratories at other institutions. They did a few years of digging, uncovering beautiful, fragile sh . 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. In the comment, During, her co-author Dennis Voeten, and her supervisor Per Ahlberg highlight anomalies in the other teams isotope analysis, a dearth of primary data, insufficiently described methods, and the fact that DePalmas team didnt specify the lab where the analyses were performed. 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. Drawing on research from paleontologist Robert DePalma, we follow DePalma's dig over the course of three years at a new site in North Dakota, unearthing remarkably well-preserved fossilised . He declined to share details because the investigation is ongoing. Robert DePalma Frederich Cichocki Manuel Dierick Robert Feeney: JPS.C.10.0001: Volume 1, 2007 "How to Make a Fossil: Part 2 - Dinosaur Mummies and Other Soft Tissue" . He reportedly helps fund his fieldwork by selling replicas of his finds to private collectors. JPS.C.2021.0002: The Paleontology, Geology and Taphonomy of the Tooth Draw Deposit; Hell Creek Formation (Maastrictian), Butte County, South Dakota. [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. "It's not just for paleo nerds. Robert DePalma is a paleontologist who holds the lease to the Tanis site and controls access to it. All rights reserved. If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. The email, which came after Science started to inquire about the case, says their concerns remain under investigation. 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 . Get more great content like this delivered right to you! Robert DePalma made headlines again in 2021 with the discovery of a leg from a Thescelosaurus dinosaur at Tanis, reported The Washington Post. Episode . Paleontologist accused of faking data in dino-killing asteroid paper. Fossils from dinosaurs and other animals from thousands of years before the asteroid impact are very hard to come by, leading some to believe . The mud and sand are dotted with glassy spherulesmany caught in the gills of the fishisotopically dated to 65.8 million years ago. The Tanis site was first identified in 2008 and has been the focus of fieldwork by paleontologist Robert DePalma since . Of his discovery, DePalma said, "It's like finding the Holy Grail clutched in the . Bottom right, a small fragment of a marine annemite shell found in the freshwater Tanis deposit. Melanie During, a paleontologist at Uppsala University in Sweden, submitted a paper for publication in the journal Nature in June 2021. [18], 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. It comprises two layers with sand and silt grading (coarse sands at the bottom, finer silt/clay particles at the top). 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. Still, people's ardor for this group of reptiles is so passionate that 12% of Americans surveyed in an Ipsos poll would resurrect T. rexes and the rest of these mysterious creatures if it were possible. [22] The discovery received widespread media coverage from 29 March 2019. [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. 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). December 10, 2021 Source: . "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. [20] The sediment appeared to have liquefied and covered the deposited biota, then quickly solidified, preserving much of the contents in three dimensions. Dinosaurs - The Final Day with David Attenborough: Directed by Matthew Thompson. 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. 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. An imagined dinosaur scene just after the asteroid strike that caused a mass extinction, from . [17] This would resolve conflicting evidence that huge water movements had occurred in the Hell Creek region near Tanis much less than an hour after impact, although the first megatsunamis from the impact zone could not have arrived at the site for almost a full day. [1] Simultaneous media disclosure had been intended via the New Yorker, but the magazine learned that a rival newspaper had heard about the story, and asked permission to publish early to avoid being scooped by waiting until the paper was published. . The fish contain isotope records and evidence of how the animals growth corresponded to the season (tree rings do the same thing). Both papers made their conclusions based on analysis of fish remains at the Tanis fossil site in North Dakota. Sir David Attenborough is to examine the mystery of the dinosaurs' last days in a BBC1/PBS/France Tlvisions feature film that will unearth a dig site hidden in the hills of North Dakota. Paleontologist Robert DePalma believes he has found evidence of the first minutes to hours of that catastrophic event. Was it a fierce volcanic eruption that toppled these creatures? Recognizing the unique nature of the site, Nicklas and Sula brought in Robert DePalma, a University of Kansas graduate student, to perform additional excavations. But relatively little fossil evidence is available from times nearer the crucial event, a difficulty known as the "Three metre problem". Artist's rendering of a large asteroid hitting Earth. Also, there is little evidence on the detailed effects of the event on Earth and its biosphere. It features what appear to be scanned printouts of manually typed tables containing the isotopic data from the fish fossils. [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. "That some competitors have cast Robert in a negative light is unfortunate and unfair," says another co-author, Mark Richards, a geophysicist at the University of California, Berkeley. Using the same formula, the Chicxulub earthquakes may have released up to 1412 times as much energy as the Chile event. Instead, the layers had never fully solidified, the fossils at the site were fragile, and everything appeared to have been laid down in a single large flood. Help News from Science publish trustworthy, high-impact stories about research and the people who shape it. The fact that spherules were found in the fishes gills suggested the animals died in the minutes to hours after the impact. But just one dinosaur bone is discussed in the PNAS studyand it is mentioned in a supplement document rather than in the paper itself. 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. DePalma characterizes their interactions differently. 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). [8] The site continues to be explored. In December 2021, a team of paleontologists published data suggesting that the asteroid impact that ended the reign of dinosaurs could be pinned down to a season springtime, 66 million years agothanks to an analysis of fossilized fish remains at a famous site in North . "It saddens me that folks are so quick to knock a study," he says. The Byte reports that the amber was found 2,000 miles away from the asteroid crater off the coast of Mexico believed to be . If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. In June 2021, paleontologist Melanie During submitted a manuscript to Nature that she suspected might create a minor scientific sensation. The CretaceousPaleogene ("K-Pg" or "K-T") extinction event around 66 million years ago wiped out all non-avian dinosaurs and many other species. "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.
