A New Look at the Day the Dinosaurs Were Extinguished After trying to discuss the matter with editors at Scientific Reports for nearly a year, During recently decided to make her suspicions public. [citation needed], At the time of the Chicxulub impact, the present-day North American continent was still forming. Though this might seem like a large number, a study intheProceedings of the National Academy of Sciencessaidit's possible that more than 1,800 different kinds of dinosaurs walked the earth. 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. DePalma says his team also invited Durings team to join DePalmas ongoing study. What's potentially so special about this site? "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. DePalma gave the name Tanis to both the site and the river. Some scientists were not happy with this proposal. 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. Several more papers on Tanis are now in preparation, Manning says, and he expects they will describe the dinosaur fossils that are mentioned in The New Yorker article. A fossil, after all, is only created under precise circumstances, with the dinosaur dying in a place that could preserve its remains in rock. "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. As of April 2019, reported findings include: The hundreds of fish remains are distributed by size, and generally show evidence of tetany (a body posture related to suffocation in fish), suggesting strongly that they were all killed indiscriminately by a common suffocating cause that affected the entire population. Also, there is little evidence on the detailed effects of the event on Earth and its biosphere. Could this provide evidence to the theory that an asteroid did indeed cause the mass extinction of the dinosaurs? ", "Tanis exhibits a depositional scenario that was unusual in being highly conducive to exceptional (largely three dimensional) preservation of many articulated carcasses (Konservat-Lagersttte). 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. If I were the editor, I would retract the paper unless [the raw data] were produced posthaste, he says. ", Since Tanis became an excavation site, several other fossils were found, including a pterosaur embryo. "Capturing the event in that much detail is pretty remarkable," concedes Blair Schoene, a geologist at Princeton University, but he says the site does not definitively prove that the impact event was the exclusive trigger of the mass extinction. Plus, tektites, pieces of natural glass formed by a meteor's impact, were scattered amid the soil. Paleontologist Accused of Making Up Data on Dinosaur-Killing Asteroid [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. 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). 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. She also removed DePalma as an author from her own manuscript, then under review at Nature. Paleontologist accused of faking data in dino-killing asteroid paper May 9, 2022 at 7:00 a.m. EDT. Still, when During submitted her manuscript to Nature on 22 June 2021, she listed DePalma as the studys second author. Bde hans far och hans farfars bror var kirurger i Florida. She and her supervisor, UU paleontologist Per Ahlberg, have shared their concerns with Science, and on 3 December, During posted a statement on the journal feedback website PubPeer claiming, we are compelled to ask whether the data [in the DePalma et al. But just one dinosaur bone is discussed in the PNAS studyand it is mentioned in a supplement document rather than in the paper itself. However, because it is rare in any case for animals and plants to be fossilized, the fossil record leaves some major questions unanswered. Did Richard Sackler Go to Jail? Where is He Now? - The Cinemaholic [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. Robert DePalma Obituary (2010) - Columbus, OH - The Columbus Dispatch Dinosaurs continue to fascinate, even though they became extinct 65 million years ago. Artist's rendering of a large asteroid hitting Earth. The study of these creatures is limited to the fossils they left behind and those provide an incomplete picture. One of these is whether dinosaurs were already declining at the time of the event due to ongoing volcanic climate change. Science asked other co-authors on the paper, including Manning, for comment, but none responded. 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 . And mass spectrometry revealed the paddlefishs fin bones had elevated levels of carbon-13, an isotope that is more abundant in modern paddlefishand presumably their closely related ancient relativesduring spring, when they eat more zooplankton rich in carbon-13. Searching in the hills of North Dakota, palaeontologist Robert DePalma makes an incredible . 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. The email, which came after Science started to inquire about the case, says their concerns remain under investigation. The paleontologist who found extinction day fossils teases - Salon . Forum News Service, provided The nerds travel to the final day of the dinosaurs reign with paleontologist Robert DePalma and the legendary Tanis Site. Please make a tax-deductible gift today. 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. The mud and sand are dotted with glassy spherulesmany caught in the gills of the fishisotopically dated to 65.8 million years ago. "He could have stumbled on something amazing, but he has a reputation for making a lot out of a little.". (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. An aspiring novelist, he attended The Ohio State University studying English and DePalma did not respond to an email request for an interview. The Hell Creek Formation was at this time very low-lying or partly submerged land at the northern end of the seaway, and the Chicxulub impact occurred in the shallow seas at the southern end, approximately 3,050km (1,900mi) from the site. We may earn a commission from links on this page. It is not even clear whether the massive waves were able to traverse the entire Interior Seaway. "The thing we can do is determine the likelihood that it died the day the meteor struck. Douglas Preston's writing about the discovery lauds it as one of the . "I just hope this hasn't been oversensationalized.". . 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. 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. How the dinosaurs died: New evidence In PBS documentary - The DePalma, Robert | Department of Geology [25] The last was published in December in Scientific Reports. Schoene and some others believe environmental turmoil caused by large-scale volcanic activity in what is now central India may have taken a toll even before the impact. Such a conclusion might provide the best evidence yet that at least some dinosaurs were alive to witness the asteroid impact. Robert DePalma uncovers a preserved articulated body of a 65-million-year-old fish at Tanis. 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. The findings each preclude correlation with either the Cantapeta or Breien, This page was last edited on 25 February 2023, at 16:30. 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 . Dont yet have access? 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. 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. He did send Science a document containing what he says are McKinneys data. Episode . 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. ^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. Paleontologists Find Perfectly Preserved Dinosaur Fossils From the Day [1]:Fig.1 and p.9181-8192 Although other flooding is evidenced in Hells Creek, the Tanis deposit does not appear to relate to any other Marine transgression (inland shoreline movement) known to have taken place. Cochran says the format of the isotopic data does not appear unusual. The site lacked the fine sediment layers he was initially looking for. He has mined a fossil site in North Dakota secretly for years. Perhaps no animal, living or dead, has captivated the world in the way that dinosaurs have. Does fossil site record dino-killing impact? JPS.C.2021.0002: The Paleontology, Geology and Taphonomy of the Tooth Draw Deposit; Hell Creek Formation (Maastrictian), Butte County, South Dakota. Of his discovery, DePalma said, "It's like finding the Holy Grail clutched in the . [31][18], A BBC documentary on Tanis, titled Dinosaurs: The Final Day, with Sir David Attenborough, was broadcast on 15 April 2022. The Crude Life Interview: Robert Depalma, paleontologist By looking through this window into the past, we can apply these lessons to today. 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 . Fossils may capture the day the dinosaurs died. Here's what - Science We werent just near the KT boundary. Impact Theory of Mass Extinctions and the Invertebrate Fossil Record, The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary. 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. 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. AAAS is a partner of HINARI, AGORA, OARE, CHORUS, CLOCKSS, CrossRef and COUNTER. The deposit may also provide some of the strongest evidence yet that nonbird dinosaurs were still thriving on impact day. In December 2021, a team of paleontologists published data . [1]:p.8 Seiche waves often occur shortly after significant earthquakes, even thousands of miles away, and can be sudden and violent. 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. Robert DePalma is a vertebrate paleontologist, based out of Florida Atlantic University (FAU), whose focus on terrestrial life of the late Cretaceous, the Chicxulub asteroid impact, and the evolution of theropod dinosaurs, was sparked by a passionate fascination with the past. September 20, 2021. paper] may be fabricated, created to fit an already known conclusion. (She also posted the statement on the OSF Preprints server today.). Your tax-deductible contribution plays a critical role in sustaining this effort. [1]:p.8193 The original paper describes the river in technical detail:[1]:Fig.1 and p.9181-8193. In lieu of controversial New Yorker article, UCD Professor weighs in on 03/30/2022. Robert DePalma. Tanis is a rich fossil site that contains a bevy of marine creatures that apparently died in the immediate fallout of the asteroid impact, or the KT extinction. Robert has been an Adjunct Professor in the Geosciences . 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. 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. 2023 American Association for the Advancement of Science. 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. We're seeing mass die-offs of animals and biomes that are being put through very stressful situations worldwide. ", A North Dakota Excavation Had One Paleontologist Rethinking The Dinosaurs' Extinction, Proceedings of the National Academy of Sciences. He says his team came up with the idea of using fossils isotopic signals to hunt for evidence of the asteroid impacts season long ago, and During adopted it after learning about it during her Tanis visita notion During rejects. As the drama unfolded, paleontologist Robert DePalma got a lot of personal and professional criticisms, including suggestions that he was showboating and driving up controversy to get additional . 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. [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. A North Dakota Excavation Had One Paleontologist Rethinking The A bad day for dinosaurs was the subject of an engaging hour-and-a-half for both paleontologists and NASA researchers. . American, said in a 2019 tweet that the findings from the site "have met with a good deal of skepticism from the paleontology community." . Abstract - Nasa . (DePalma and colleagues published a paper in the Proceedings of the National Academy of Sciences in 2019 that described finding these spherules in different samples analyzed at another facility.).
