2022.08.24 WednesdayKansas University, via Agence France-Presse Getty Images Another question about dinosaurs is what caused their extinction and there are many theories about that, too. . 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. Fossil Site Reveals Day That Meteor Hit Earth and, Maybe, Wiped Out DePalma's dinosaur study, published in Scientific Reports in December 2021, . Underneath a freshwater paddlefish skeleton, a mosasaur tooth appeared. During and DePalma spent 10 days in the field together, unearthing fossils of several paddlefish and species closely related to modern sturgeon called acipenseriformes. Ritchie Hall | Earth, Energy & Environment Center 1414 Naismith Drive, Room 254 Lawrence, KS 66045 geology@ku.edu 785-864-4974 Paleontologist Robert DePalma, featured in PBS's "Dinosaur Apocalypse," discusses an astonishing trove of fossils. But others question DePalma's interpretations. 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. He declined to share details because the investigation is ongoing. DePalma holds the lease to the Tanis site, which sits on private land, and controls access to it. 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. He had already named the genus Dakotaraptor when others identified it as belonging to a prehistoric turtle. Ahlberg shared her concerns. If the data were generated in a stable isotope lab, that lab had a desktop computer that recorded results, he says, and they should still be available. [12] It marked the end of the Cretaceous period and the Mesozoic Era, opening the Cenozoic Era that continues today. Bottom right, a small fragment of a marine annemite shell found in the freshwater Tanis deposit. During and Ahlberg, a member of the Royal Swedish Academy of Sciences, question whether they exist. "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. 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. A New Look at the Day the Dinosaurs Were Extinguished The findings are the work of paleontologist Robert DePalma, who has previously attracted controversy. In June 2021, paleontologist Melanie During submitted a manuscript to Nature that she suspected might create a minor scientific sensation. Comes with twelve different courses comprised of a huge number of lessons, and each one will help you learn more about Python itself, and can be accessed when you want and as often as you want forever, making it ideal for learning a new skill. American, said in a 2019 tweet that the findings from the site "have met with a good deal of skepticism from the paleontology community." . [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. Something is fishy here, says Mauricio Barbi, a high energy physicist at the University of Regina who specializes in applying physics methods to paleontology. The three-metre problem encompasses that . This had initially been a seaway between separate continents, but it had narrowed in the late Cretaceous to become, in effect, a large inland extension to the Gulf of Mexico. The Crude Life Interview: Robert Depalma, paleontologist [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. This dinosaur, a giant reptilian, lived during the Early Cretaceous period in oceans. 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. "I hope this is all legitI'm just not 100% convinced yet," says Thomas Tobin, a geologist at the University of Alabama in Tuscaloosa. A study published by paleontologist Robert DePalma in December last year concluded that dinosaurs went extinct during the springtime. The raw data are missing, he says, because the scientist who ran the analyses died years prior to the papers publication, and DePalma has been unable to recover them from his deceased collaborators laboratory. Douglas Preston's writing about the discovery lauds it as one of the . Did the Dinosaurs Die on a Pleasant North Dakota Spring Day? In December 2021, a team of paleontologists published data . "I just hope this hasn't been oversensationalized.". Robert DePalma is a paleontologist who holds the lease to the Tanis site and controls access to it. Dinosaurs have been dead for so long,'" DePalma told The Washington Post. 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. Does fossil site record dino-killing impact? Over the next 2 years, During says she made repeated attempts to discuss authorship with DePalma, but he declined to join her paper. New Evidence Shows Experts Have Dinosaurs' Extinction All Wrong 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 . A North Dakota Excavation Had One Paleontologist Rethinking The This program was also aired as "Dinosaur Apocalypse: The Last Day" on PBS Nova starting 11 May 2022.[9][32]. [18], DePalma began excavating systematically in 2012[1]:11 and quickly found the site to contain very unusual and promising features. North Dakota site shows wreckage from same object that killed the Sackler has three children Rebecca, Marianna, and David with his now ex-wife, Beth Sackler. 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. 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. 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. 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 . Dinosaurs continue to fascinate, even though they became extinct 65 million years ago. Why this stunning dinosaur fossil discovery has scientists stomping mad More: Science Publisher Retracts 44 Papers for Being Utter Nonsense, We may earn a commission from links on this page. 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. [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. All of these factors seemed strange and confused the paleontologists. 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 112-mile Chicxulub crater, located on the Yucatn Peninsula, contains the same mineral iridium as the KT layer, and it's often cited as further proof that a giant asteroid was responsible for killing dinosaurs (perBoredom Therapy). Today, their fossils lie jumbled together at a site in North Dakota. . Isaac Schultz. The end-Cretaceous Chicxulub impact triggered Earth's last mass-extinction, extinguishing ~ 75% of species diversity and facilitating a global ecological shift to mammal-dominated biomes. As detailed by Science, the isotopic data in DePalmas paper was collected by archaeologist Curtis McKinney, who died in 2017. With Gizmodos Molly Taft | Techmodo. The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth. DePalma, now a Ph.D. student at the University of Manchester, vehemently denies any wrongdoing. The day 66 million years ago when the reign of the dinosaurs ended and the rise of . 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.. By looking through this window into the past, we can apply these lessons to today. A fossil, after all, is only created under precise circumstances, with the dinosaur dying in a place that could preserve its remains in rock. 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. Images: Top right, Robert DePalma and Peter Larson conduct field research in Tanis. The nerds travel to the final day of the dinosaurs reign with paleontologist Robert DePalma and the legendary Tanis Site. By Robert Sanders, Media relations | March 29, 2019. With David Attenborough, Robert DePalma, Phillip Manning. Tobin says the PNAS paper is densely packed with detail from paleontology, sedimentology, geochemistry, and more. 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. Forum News Service, provided 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. Bob was born in Newark, NJ on December 26, 1948 to the late James and Rose DePalma. It could be just one factor in a series of environmental events that led to their extinction. According to Science, DePalma was incorrect in 2015 when he believed he discovered a bone from a new type of dinosaur. A wealth of other evidence has persuaded most researchers that the impact played some role in the extinctions. TV tonight: watch out dinosaurs, that big asteroid is coming - and so Tanis is part of the heavily studied Hell Creek Formation, a group of rocks spanning four states in North America renowned for many significant fossil discoveries from the Upper Cretaceous and lower Paleocene. Study leader Robert DePalma conducts field research at the Tanis site. [21], The site was originally a point bar - a gently sloped crescent-shaped area of deposit that accumulates on the inside bend of streams and rivers below the slip-off slope. 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 is not even clear whether the massive waves were able to traverse the entire Interior Seaway. 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. Dinosaurs' Last Spring: Groundbreaking Study Pinpoints Timing of Since 2013, Sackler has resided at a private property on the outskirts of Austin, Texas. He reportedly helps fund his fieldwork by selling replicas of his finds to private collectors. Tanis at the time was located on a river that may have drained into the shallow sea covering much of what is now the eastern and southern United States. The study of these creatures is limited to the fossils they left behind and those provide an incomplete picture. Th We may earn a commission from links on this page. 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. When asked for more information on the situation on January 3, a spokesperson for Scientific Reports said there were no updates. 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. 2023 American Association for the Advancement of Science. According to the Science article, During suspects that DePalma, eager to claim credit for the finding, wanted to scoop herand made up the data to stake his claim.. 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" . 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. 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 last mass extinction 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. In June 2021, paleontologist Melanie During submitted a . Episode #52: Your Mother Was a Vetulicolian and Your Father Smelt of Elderberries with Henry Gee . 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 . 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. 66 million-year-old deathbed linked to dinosaur-killing meteor 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. And, if they are not forthcoming, there are numerous precedents for the retraction of scholarly articles on that basis alone..

Seasonal calibration of the end-cretaceous Chicxulub impact event - Nature 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. Robert DePalma. 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. He says the reviewers for the higher-profile journal made requests that were unreasonable for a paper that simply outlines the discovery and initial analysis of Tanis. 2 / 4: Robert A.

If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. 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. But a former colleague, Melanie During at Uppsala University, asserts that DePalma created data to support the conclusion.

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. The paper cleared peer review at PNAS within about 4 months. Dinosaur Fossil From Day Extinction Asteroid Hit Earth - Insider 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. During described the findings in her 2018 masters thesis, a copy of which she shared with DePalma in February 2019. DEPALMA Robert Michael DePalma Jr. of Columbus, Ohio passed away unexpectedly February 15, 2010 at the age of 26 years.

Impact Theory of Mass Extinctions and the Invertebrate Fossil Record, The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary. 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. The Tanis site was first identified in 2008 and has been the focus of fieldwork by paleontologist Robert DePalma since . Numerous famous fossils of plants and animals, including many types of dinosaur fossils, have been discovered there. [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. Taylor Mickal/NASA. They've been presented at meetings in various ways with various associated extraordinary claims," a West Coast paleontologist said to The New Yorker. In December 2021, DePalma and his colleagues published an important paper . Robert DePalma | KU Geology - University Of Kansas The latter paper was published by a team led by Robert DePalma, Durings former collaborator and a paleontologist now at 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. September 20, 2021. [22] The discovery received widespread media coverage from 29 March 2019. [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". "No one is an expert on all of those subjects," he says, so it's going to take a few months for the research community to digest the findings and evaluate whether they support such extraordinary conclusions. If not, well, fraud is on the table.. 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. The site lacked the fine sediment layers he was initially looking for. A field assistant, Rudy Pascucci, left, and the paleontologist Robert DePalma, right, at DePalma's dig site.

An aspiring novelist, he attended The Ohio State University studying English and Eiler agrees. They seem to have left the raw data out of the manuscript deliberately, he says. 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. The site was originally discovered in 2008 by University of North Georgia Professor Steve Nicklas and field paleontologist Rob Sula. Scarred Duckbill Dinosaur Escaped T.
