September 20, 2021. Credit. "That's the first ever evidence of the interaction between life on the last day of the Cretaceous and the impact event," team member Phillip Manning, a paleontologist at the University of Manchester in the United Kingdom, told the publication. 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. 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 . We werent just near the KT boundary. Please make a tax-deductible gift today. The findings are the work of paleontologist Robert DePalma, who has previously attracted controversy. Mr. Frithiof was able to broker an agreement between Paleo Prospectors and DePalma. Tanis is on private land; DePalma holds the lease to the site and controls access to it. Top left, a shocked mineral from Tanis. November 5, 2015. [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. Tanis is a significant site because it appears to record the events from the first minutes until .

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. 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. Despite more than 200 years of study, paleontologists have named only several hundred species. After his excavations at the Tanis site in North Dakota unearthed a huge trove of fish fossils that were likely blasted by the asteroid impact . Both papers studied 66-million-year-old paddlefish jawbones and sturgeon fin spines from Tanis. The findings each preclude correlation with either the Cantapeta or Breien, This page was last edited on 25 February 2023, at 16:30. 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. Others defend DePalma, like his co-author, Mark Richards, a geophysicist at the University of California, Berkeley. Dinosaurs have been dead for so long,'" DePalma told The Washington Post. 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. DePalma, now a Ph.D. student at the University of Manchester, vehemently denies any wrongdoing. (Formula and details)The 2011 Thoku earthquake and tsunami was estimated at magnitude 9.1, so the energy released by the Chicxulub earthquakes, estimated at up to magnitude 11.5, may have been up to 101.5 x (11.59.1) = 3981 times larger. 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. [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. There was a fossil everywhere I turned., After she returned to Amsterdam, During asked DePalma to send her the samples she had dug up, mostly sturgeon fossils. 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. These include many rare and unique finds, which allow unprecedented examination of the direct effects of the impact on plants and animals alive at the time of the large impact some 3,000km (1,900mi) distant. In the caravan are microscopes . He reportedly helps fund his fieldwork by selling replicas of his finds to private collectors. 2023 American Association for the Advancement of Science. Astonishment, skepticism greet fossils claimed to record dinosaur-killing asteroid impact. Dinosaurs continue to fascinate, even though they became extinct 65 million years ago. The site was systematically excavated by Robert DePalma over several years beginning in 2012, working in near total secrecy. 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. 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. Searching in the hills of North Dakota, palaeontologist Robert DePalma makes an incredible . 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. 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. "I hope this is all legitI'm just not 100% convinced yet," says Thomas Tobin, a geologist at the University of Alabama in Tuscaloosa. 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. Proposed by Luis and Walter Alvarez, it is now widely accepted that the extinction was caused by a huge asteroid or bolide that impacted Earth in the shallow seas of the Gulf of Mexico, leaving behind the Chicxulub crater. The 1960 Valdivia Chile earthquake was the most powerful ever recorded, estimated at magnitude 9.4 to 9.6. Retaliation is also prohibited by university policy. [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". Get more great content like this delivered right to you! Even as a child, DePalma wondered what the Cretaceous was like. All of these factors seemed strange and confused the paleontologists. Your tax-deductible contribution plays a critical role in sustaining this effort. DePalma's team says the killing is captured in forensic detail in the 1.3-meter-thick Tanis deposit, which it says formed in just a few hours, beginning perhaps 13 minutes after impact. 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. All rights reserved. Robert DePalma, a curator at the Palm Beach Museum of Natural History, found some rare fossils close to Bowman, North Dakota, in 2013 that led to a hypothesis of his own. ", "Tanis exhibits a depositional scenario that was unusual in being highly conducive to exceptional (largely three dimensional) preservation of many articulated carcasses (Konservat-Lagersttte). If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. More: Science Publisher Retracts 44 Papers for Being Utter Nonsense, We may earn a commission from links on this page. "I've been asked, 'Why should we care about this? 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" . 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. 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. Some scientists say this destroyed the dinosaurs; others believe they thrived during the period. While DePalma corrected his claim, his reputation still took a hit. Last month, During published a comment on PubPeer alleging that the data in DePalmas paper may be fabricated. It features what appear to be scanned printouts of manually typed tables containing the isotopic data from the fish fossils. Petrified fish with glass spheres, called ejecta, were also at the site. [5] The microtektites were present and concentrated in the gills of about 50% of the fossilized fish, in amber, and buried in the small pits in the mud which they had made when they contemporaneously impacted. As a part of the settlement, the Sacklers will have immunity against any and all future civil litigation. "He could have stumbled on something amazing, but he has a reputation for making a lot out of a little.". A version of this story appeared in Science, Vol 378, Issue 6625. 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. . With this deposit, we can chart what happened the day the Cretaceous died. . "That some competitors have cast Robert in a negative light is unfortunate and unfair," Richards told Science. Her mentor there, paleontologist Jan Smit, introduced her to DePalma, at the time a graduate student at the University of Kansas, Lawrence. One of these is whether dinosaurs were already declining at the time of the event due to ongoing volcanic climate change. Some scientists were not happy with this proposal. The extinction event caused by this impact began the Cenozoic, in which mammals - including humans - would eventually come to dominate life on Earth. It comprises two layers with sand and silt grading (coarse sands at the bottom, finer silt/clay particles at the top). All rights reserved. Also, there is little evidence on the detailed effects of the event on Earth and its biosphere. Tanis is a site of paleontological interest in southwestern North Dakota, United States. 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.. 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). The iridium-enriched CretaceousPaleogene boundary, which separates the Cretaceous from the Cenozoic, is distinctly visible as a discontinuous thin marker above and occasionally within the formation. During the long process of discussing these options they decided to submit their paper, he says. What's potentially so special about this site? 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. Episode . Of his discovery, DePalma said, "It's like finding the Holy Grail clutched in the . Could this provide evidence to the theory that an asteroid did indeed cause the mass extinction of the dinosaurs? Now, Robert DePalma, a paleontologist at the Palm Beach Museum of Natural History and a graduate student at the University of Kansas, claims to have unveiled an unprecedented time capsule of this . Notably, the powerful magnitude 9.0 9.1 Thoku earthquake in 2011, slower secondary waves traveled over 8,000km (5,000mi) in less than 30 minutes to cause seiches around 1.51.8m (4.95.9ft) high in Norway. 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 . In turn, the fish remains revealed the season their lives endedergo, the precise timing of the devastating asteroid strike to the Yucatn Peninsula. The co-authors included Walter Alvarez and Jan Smit, both renowned experts on the K-Pg impact and extinction. Robert DePalma uncovers a preserved articulated body of a 65-million-year-old fish at Tanis. Bottom right, a small fragment of a marine annemite shell found in the freshwater Tanis deposit. (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.). Artist's rendering of a large asteroid hitting Earth. 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. [2], A paper documenting Tanis was released as a prepublication on 1 April 2019. DePalma and his group knew the creature could not have survived in North Dakota's fresh waters during the prehistoric age. though Robert DePalma's love of the dead and buried was anything but . Special to The Forum. Last modified on Fri 8 Apr 2022 11.20 EDT. This dinosaur, a giant reptilian, lived during the Early Cretaceous period in oceans. That same year, encouraged by a Dutch award for the thesis, she began to prepare a journal article. 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. 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. Fish were swept up in mud and sand in the aftermath of a great wave sparked by the Chicxulub impact, paleontologists say. "I just hope this hasn't been oversensationalized.". . Still, when During submitted her manuscript to Nature on 22 June 2021, she listed DePalma as the studys second author. "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. [1]:p.8 Seiche waves often occur shortly after significant earthquakes, even thousands of miles away, and can be sudden and violent. Subscribe to News from Science for full access to breaking news and analysis on research and science policy. She also removed DePalma as an author from her own manuscript, then under review at Nature. 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.. Its author, Douglas Preston, who learned of the find from DePalma in 2013, writes that DePalma's team found dinosaur bones caught up in the 1.3-meter-thick deposit, some so high in the sequence that DePalma suspects the carcasses were floating in the roiling water. 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. Appropriate editorial action will be taken once this matter is resolved.. Michael Price is associatenews editor for Science, primarily covering anthropology, archaeology, and human evolution. 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. 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 . Some of the gripes occurred because DePalma first shared his story with a mainstream publication, The New Yorker, instead of a more academic-based journal, said Bored Therapy. However, because it is rare in any case for animals and plants to be fossilized, the fossil record leaves some major questions unanswered. These fossils were delivered for research to the Field Museum of Natural History in Chicago. The Chicxulub impact is believed to have triggered earthquakes estimated at magnitude 10 11.5,[1]:p.8 releasing up to 4000 times the energy of the Tohoku quake.Note 1 Co-author Mark Richards, a professor of earth sciences focusing on dynamic earth crust processes[16] suggests that the resulting seiche waves would have been approximately 10100m (33328ft) high in the Western Interior Seaway near Tanis[1]:p.8 and credibly, could have created the 10 11 m (33 36 feet) high water movements evidenced inland at the site; the time taken by the seismic waves to reach the region and cause earthquakes almost exactly matched the flight time of the microtektites found at the site. Was it a fierce volcanic eruption that toppled these creatures? But no one has found direct evidence of its lethal effects. He declined to share details because the investigation is ongoing. They've been presented at meetings in various ways with various associated extraordinary claims," a West Coast paleontologist said to The New Yorker. And, if they are not forthcoming, there are numerous precedents for the retraction of scholarly articles on that basis alone.. The latter paper was published by a team led by Robert DePalma, Durings former collaborator and a paleontologist now at the University of Manchester.

[31][18], A BBC documentary on Tanis, titled Dinosaurs: The Final Day, with Sir David Attenborough, was broadcast on 15 April 2022. Tanis is a site of paleontological interest in southwestern North Dakota, United States. This program was also aired as "Dinosaur Apocalypse: The Last Day" on PBS Nova starting 11 May 2022.[9][32]. 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. This explanation was proposed long before DePalma's discovery. 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. If Tanis is all it is claimed to be, that debateand many others about this momentous day in Earth's historymay be over. Others later pointed out that the reconstructed skeleton includes a bone that really belonged to a turtle; DePalma and his colleagues issued a correction. Something is fishy here, says Mauricio Barbi, a high energy physicist at the University of Regina who specializes in applying physics methods to paleontology. By 2013, he was still studying the site, which he named "Tanis" after the ancient Egyptian city of the same name,[5] and had told only three close colleagues about it. Robert has been an Adjunct Professor in the Geosciences . Dont yet have access? Recognizing the unique nature of the site, Nicklas and Sula brought in Robert DePalma, a University of Kansas graduate student, to perform additional excavations. The paleontologist believed that this new information further supported the theory that an asteroid killed the dinosaursalong with 75 percent of the animals and plants on Earth 66 million year ago. "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. 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. JPS.C.2021.0002: The Paleontology, Geology and Taphonomy of the Tooth Draw Deposit; Hell Creek Formation (Maastrictian), Butte County, South Dakota. DePalma gave the name Tanis to both the site and the river. They did a few years of digging, uncovering beautiful, fragile sh . [1]:p.8192 The river flowed Eastward (other than impact driven waves),[1]:p.8192 with inland being to the West; Tanis itself was therefore in an ancient river valley close to the Westward shore of the Interior Seaway. The Tanis site was first identified in 2008 and has been the focus of fieldwork by paleontologist Robert DePalma since . The paleontologist believed that this new information further supported the theory that an asteroid . By looking through this window into the past, we can apply these lessons to today. The deposit itself is about 1.3m thick, sharply overlaying the point bar, in a drape-like manner. Sackler has three children Rebecca, Marianna, and David with his now ex-wife, Beth Sackler. 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. The site lacked the fine sediment layers he was initially looking for. 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. [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. A researcher claims that Robert DePalma published a faulty study in order to get ahead of her own work on the Tanis fossil site. A version of this story appeared in Science, Vol 378, Issue 6625. Manning confirms rumors that the study was initially submitted to a journal with a higher impact factor before it was accepted at PNAS. 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. 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. Raising the Bar: Chocolate's History, Art, and Taste With Sophia Contreras Rea American, said in a 2019 tweet that the findings from the site "have met with a good deal of skepticism from the paleontology community." . 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. The seiche waves exposed and covered the site twice, as millions of tiny microtektite droplets and debris from the impact were arriving on ballistic trajectories from their source in what is now the Yucatn Peninsula. 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. These powerful creatures prowled the Earth for about 165 million years before mysteriously disappearing (via U.S. Geological Survey). He is survived by his loving wife,. 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. An aspiring novelist, he attended The Ohio State University studying English and By Nicole Karlis Senior Writer. . If I were the editor, I would retract the paper unless [the raw data] were produced posthaste, he says. During and DePalma spent 10 days in the field together, unearthing fossils of several paddlefish and species closely related to modern sturgeon called acipenseriformes. His advisor suggested seeking a similar site, closer to the K-Pg boundary layer. 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. 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. Gizmodo covered the research at the time. 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. That "disconnect" bothers Steve Brusatte, a paleontologist at the University of Edinburgh. Robert DePalma. Robert DePalma made headlines again in 2021 with the discovery of a leg from a Thescelosaurus dinosaur at Tanis, reported The Washington Post. "It's not just for paleo nerds.
