"After a while, we decided it wasn't a good route to go down," he says. The site, dubbed "Tanis," first underwent excavation in 2012, with DePalma and his team digging along a section known as the Hell Creek Formation (via Boredom Therapy). 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. 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. 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. DePalma's dinosaur study, published in Scientific Reports in December 2021, . In June 2021, paleontologist Melanie During submitted a . 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. Ive done quite a few excavations by now, and this was the most phenomenal site Ive ever worked on, During says. Although fish fossils are normally deposited horizontally, at Tanis, fish carcasses and tree trunks are preserved haphazardly, some in near vertical orientations, suggesting they were caught up in a large volume of mud and sand that was dumped nearly instantaneously.
Why this stunning dinosaur fossil discovery has scientists stomping mad Disbelievers of this supposition, though, point to the lack of fossils in the KT layer as proof that this thesis is false more fossils are discovered some 10 feet underneath the layer. "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. "I just hope this hasn't been oversensationalized.". DePalma and his group knew the creature could not have survived in North Dakota's fresh waters during the prehistoric age.
The paleontologist who found extinction day fossils teases - Salon Get more great content like this delivered right to you! 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. Isaac Schultz. But a former colleague, Melanie During at Uppsala University, asserts that DePalma created data to support the conclusion. 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- 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. . However, because it is rare in any case for animals and plants to be fossilized, the fossil record leaves some major questions unanswered. The study of these creatures is limited to the fossils they left behind and those provide an incomplete picture. Dinosaurs - The Final Day with David Attenborough: Directed by Matthew Thompson. 01/05/2021. 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. Both papers made their conclusions based on analysis of fish remains at the Tanis fossil site in North Dakota. "It's not just for paleo nerds. [1]:p.8193 The original paper describes the river in technical detail:[1]:Fig.1 and p.9181-8193. 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. 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. JPS.C.2021.0002: The Paleontology, Geology and Taphonomy of the Tooth Draw Deposit; Hell Creek Formation (Maastrictian), Butte County, South Dakota. [12] It marked the end of the Cretaceous period and the Mesozoic Era, opening the Cenozoic Era that continues today. 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. Searching in the hills of North Dakota, palaeontologist Robert DePalma makes an incredible . When asked for more information on the situation on January 3, a spokesperson for Scientific Reports said there were no updates. How to Know If the Heat Is Making You Sick. Robert DePalma is a paleontologist who holds the lease to the Tanis site and controls access to it. 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 .

Astonishment, skepticism greet fossils claimed to record - Science They've been presented at meetings in various ways with various associated extraordinary claims," a West Coast paleontologist said to The New Yorker. [citation needed], At the time of the Chicxulub impact, the present-day North American continent was still forming. Science journalism's obligation to truth.
Did Richard Sackler Go to Jail? Where is He Now? - The Cinemaholic 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.
The Day the Dinosaurs Died | The New Yorker The paper cleared peer review at PNAS within about 4 months. Boca paleontologist Robert de Palma uncovers evidence of the day the dinosaurs diedand how it connects to homo sapiens. If Tanis is all it is claimed to be, that debateand many others about this momentous day in Earth's historymay be over. 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. The chief editor of Scientific Reports, Rafal Marszalek, says the journal is aware of concerns with the paper and is looking into them. [1]:p.8 Seiche waves often occur shortly after significant earthquakes, even thousands of miles away, and can be sudden and violent. Th The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth. The media article was published several days before an accompanying research paper on the site came out in the Proceedings of the National Academy of Sciences. 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. Taylor Mickal/NASA. We absolutely would not, and have not ever, fabricated data and/or samples to fit this or another teams results, he wrote in an email to Science. Robert DePalma made headlines again in 2021 with the discovery of a leg from a Thescelosaurus dinosaur at Tanis, reported The Washington Post.
"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. The site, after all, does not conclusively prove that the asteroid's impact actually caused the dinosaurs' demise, reported Science. Could this provide evidence to the theory that an asteroid did indeed cause the mass extinction of the dinosaurs? At his suggestion, she wrote a formal letter to Scientific Reports. "Robert has been meticulous, borderline archaeological in his excavation approach," says Manning, who has been working at Tanis from the beginning. Raw machine data are seldom supplied to end users (myself included) who contract for isotope analyses from a lab that does them., Cochran says DePalma erred in not including these data and their origins in his original manuscript, but the bottom line is that I have no reason to distrust the basic data or in any way believe that it was fabricated., Eiler disputes this. But no one has found direct evidence of its lethal effects. 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. "He could have stumbled on something amazing, but he has a reputation for making a lot out of a little.". Petrified fish with glass spheres, called ejecta, were also at the site.

DePalma, Robert | Department of Geology How we reported a controversial story about the day the dinosaurs died A researcher claims that Robert DePalma published a faulty study in order to get ahead of her own work on the Tanis fossil site. 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. These dimensions are in the upper size range for point bars in the Hell Creek Formation and compare favorably with modern rivers with large channels that are tens to hundreds of meters wide", "[The Event flood deposits are] indicative of a westward or inland flow direction that is opposite of the natural (ancient) current of the Tanis River", "[The] Event Deposit is restricted to (an ancient) river valley and is conspicuously absent from the adjacent floodplains. [1]:pg.11 Key findings were presented in two conference papers in October 2017.
Paleontologist accused of faking data in dino-killing asteroid paper He did send Science a document containing what he says are McKinneys data. But McKinneys former department chair, Pablo Sacasa, says he is not aware of McKinney ever collaborating with laboratories at other institutions. 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. 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 .
Shards of Asteroid That Killed the Dinosaurs May Have Been Found in The death scene from within an hour of the impact has been excavated at an unprecedented . 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. He is survived by his loving wife,. 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.
A North Dakota Excavation Had One Paleontologist Rethinking The And, if they are not forthcoming, there are numerous precedents for the retraction of scholarly articles on that basis alone..
Scientists find fossil of dinosaur 'killed on day of asteroid strike' If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. The Tanis site was first identified in 2008 and has been the focus of fieldwork by paleontologist Robert DePalma since . More: Science Publisher Retracts 44 Papers for Being Utter Nonsense, We may earn a commission from links on this page. These powerful creatures prowled the Earth for about 165 million years before mysteriously disappearing (via U.S. Geological Survey). 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. The situation was first reported by the publication Science last month. The papers chief finding was that the large asteroid that slammed into Earth at the end of the Cretaceous struck in spring, a conclusion reached by studying fossilized fish found in North Dakota. ^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.

Robert DePalma | KU Geology - University Of Kansas 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. This dinosaur, a giant reptilian, lived during the Early Cretaceous period in oceans. 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. 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. [25] The last was published in December in Scientific Reports. DePalma did not respond to an email request for an interview. 2021 (106) December (5) November (8) October (8 . A version of this story appeared in Science, Vol 378, Issue 6625. Some scientists were not happy with this proposal. DePalma holds the lease to the Tanis site, which sits on private land, and controls access to it. The nerds travel to the final day of the dinosaurs reign with paleontologist Robert DePalma and the legendary Tanis Site.
Scientists may have found fragments of THE asteroid that wiped out the 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.

New Evidence May Shed Light on Extinction Event That Killed the - MSN 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. 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. We werent just near the KT boundary. 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. Some scientists say this destroyed the dinosaurs; others believe they thrived during the period. A A. Paleontologist Robert DePalma has done it again. [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. 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.

Did the Dinosaurs Die on a Pleasant North Dakota Spring Day? Tanis is a significant site because it appears to record the events from the first minutes until a few hours after the impact of the giant Chicxulub asteroid in extreme detail. Impact Theory of Mass Extinctions and the Invertebrate Fossil Record, The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary.
TV Paleontologist Facing Backlash After Reportedly Faking Data A researcher claims that Robert DePalma published a faulty study in order to get ahead of her own work on the Tanis fossil site. 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.
Robert DEPALMA | Postgraduate Researcher | The University of Manchester By Nicole Karlis Senior Writer. 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 events at Tanis occurred far too soon after impact to be caused by the megatsunamis expected from any large impact near large bodies of water. "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.
The Crude Life Interview: Robert Depalma, paleontologist "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. [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". They had breathed in early debris that fell into water, in the seconds or minutes before death. The email, which came after Science started to inquire about the case, says their concerns remain under investigation. Ahlberg shared her concerns. [31][18], A BBC documentary on Tanis, titled Dinosaurs: The Final Day, with Sir David Attenborough, was broadcast on 15 April 2022. Sackler has three children Rebecca, Marianna, and David with his now ex-wife, Beth Sackler. 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. The paleontologist believed that this new information further supported the theory that an asteroid . Over the next 2 years, During says she made repeated attempts to discuss authorship with DePalma, but he declined to join her paper. Since 2012, paleontologist Robert DePalma has been excavating a site in North Dakota that he thinks is "an incredible and unprecedented discovery". "We're never going to say with 100 percent certainty that this leg came from an animal that died on that day," the scientist said to the publication.
High impact paleontology - Medium Tanis is a significant site because it appears to record the events from the first minutes until . Some scientists question Robert DePalma's methods.

During described the findings in her 2018 masters thesis, a copy of which she shared with DePalma in February 2019. 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. Robert James DePalma, 71, a longtime Florida resident passed away Tuesday, May 12, 2020 at his residence in Fort Myers, FL. [2], A paper documenting Tanis was released as a prepublication on 1 April 2019. Robert DePalma. 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. Robert DePalma reveals the Tanis site discoveries he couldn't talk about in Part One.
TV scientist accused of FAKING data in a major dinosaur study 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.
