How we reported a controversial story about the day the dinosaurs died "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. 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 . Robert has been an Adjunct Professor in the Geosciences . 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. Ahlberg shared her concerns. DePalma and his group knew the creature could not have survived in North Dakota's fresh waters during the prehistoric age. Paleontologist Accused of Making Up Data on Dinosaur-Killing Asteroid 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. Scientists find fossil of dinosaur 'killed on day of asteroid strike' Robert DePalma (right) and Walter Alvarez (left) at the Tanis site in North Dakota. Until a few years ago, some researchers had suspected the last dinosaurs vanished thousands of years before the catastrophe. The email, which came after Science started to inquire about the case, says their concerns remain under investigation. The findings each preclude correlation with either the Cantapeta or Breien, This page was last edited on 25 February 2023, at 16:30. DePalma's dinosaur study, published in Scientific Reports in December 2021, . [23], As of April 2019, several other papers were stated to be in preparation, with further papers anticipated by DePalma and co-authors, and some by visiting researchers.[24]. The extinction event caused by this impact began the Cenozoic, in which mammals - including humans - would eventually come to dominate life on Earth. Science asked other co-authors on the paper, including Manning, for comment, but none responded. [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. 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. The mud and sand are dotted with glassy spherulesmany caught in the gills of the fishisotopically dated to 65.8 million years ago. Victoria Wicks: DePalma's name is listed first on the research article published in April last year, and he has been the primary spokesman on the story . 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. Robert DePalma made headlines again in 2021 with the discovery of a leg from a Thescelosaurus dinosaur at Tanis, reported The Washington Post. It reads: Editors Note: Readers are alerted that the reliability of data presented in this manuscript is currently in question. The nerds travel to the final day of the dinosaurs reign with paleontologist Robert DePalma and the legendary Tanis Site. 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. Paleontologist Robert DePalma Presents in NASA Goddard Colloquium on He says he did so because the isotopic data had been supplied as a non-digital data set by a collaborator, archaeologist Curtis McKinney of Miami Dade College, who died in 2017. Fossilized snapshot of mass death found on North Dakota ranch 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 . The 1960 Valdivia Chile earthquake was the most powerful ever recorded, estimated at magnitude 9.4 to 9.6. Isaac Schultz. 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. 01/05/2021. "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. Paleo Nerds: A Prehistoric Podcast | Paleo Nerds December 10, 2021 Source: . Tanis is a site of paleontological interest in southwestern North Dakota, United States.

The event included waves with at least 10 meters run-up height (the vertical distance a wave travels after it reaches land). But others question DePalma's interpretations. [8] The site continues to be explored. But relatively little fossil evidence is available from times nearer the crucial event, a difficulty known as the "Three metre problem". 2023 American Association for the Advancement of Science. In December 2021, a team of paleontologists published data . Some scientists were not happy with this proposal. Retaliation is also prohibited by university policy.

Sir David Attenborough's Latest BBC Film To Unearth - Deadline DePalma believed that the fossils found in Tanis, which sat on the KT layer, became collected there just after the asteroid struck the earth. 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. Since 2012, paleontologist Robert DePalma has been excavating a site in North Dakota that he thinks is "an incredible and unprecedented discovery". This program was also aired as "Dinosaur Apocalypse: The Last Day" on PBS Nova starting 11 May 2022.[9][32]. Astonishment, skepticism greet fossils claimed to record - Science 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. It needs to be explained. Despite more than 200 years of study, paleontologists have named only several hundred species. Every summer, for the past eight years, paleontologist Robert de Palma and a caravan of colleagues drive 2,257 miles from Boca Raton to the sleepy North Dakota town of Bowman. The deposit itself is about 1.3m thick, sharply overlaying the point bar, in a drape-like manner. This further evidences the violent nature of the event. In June 2021, paleontologist Melanie During submitted a manuscript to Nature that she suspected might create a minor scientific sensation. Numerous famous fossils of plants and animals, including many types of dinosaur fossils, have been discovered there. After trying to discuss the matter with editors at Scientific Reports for nearly a year, During recently decided to make her suspicions public. [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. Dinosaurs continue to fascinate, even though they became extinct 65 million years ago. 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. 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. What we do know is that during the Jurassic period, great global upheaval occurred with increases in temperature, surging sea levels, and less humidity. 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. 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. Both Landman and Cochran confirmed to Science they had reviewed the data supplied by DePalma in January, apparently following Scientific Reportss request for additional clarification on the issues raised by During and Ahlberg immediately after the papers publication. "After a while, we decided it wasn't a good route to go down," he says. Robert DePalma is a paleontologist who holds the lease to the Tanis site and controls access to it. Published May 11, 2022 6:09PM (EDT) 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. Han vxte upp i Boca Raton i Florida. In June 2021, paleontologist Melanie During submitted a . The site lacked the fine sediment layers he was initially looking for. Sir David Attenborough presents this landmark documentary which brings to life, in unprecedented detail, the lost world of the very last days of the dinosaurs. Bde hans far och hans farfars bror var kirurger i Florida. Manning confirms rumors that the study was initially submitted to a journal with a higher impact factor before it was accepted at PNAS. Traduzione di "i paleontologi che" in inglese - Reverso Context It can be divided into two layers, a bottom layer about 0.5m thick ("unit 1"), and a top layer about 0.8m thick (unit 2), capped by a 1 2cm layer of impactite tonstein that is indistinguishable from other dual layered KPg impact ejection materials found in Hells Creek, and finally a layer around 6cm thick of plant remains. Impact Theory of Mass Extinctions and the Invertebrate Fossil Record, The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary. [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. 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. 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. Searching in the hills of North Dakota, palaeontologist Robert DePalma makes an incredible . Eiler agrees. Shards of Asteroid That Killed the Dinosaurs May Have Been Found in . The paleontologist who found extinction day fossils teases - Salon 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. Top left, a shocked mineral from Tanis. Dinosaur Fossil From Day Extinction Asteroid Hit Earth - Insider 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. 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. He later wrote a piece for the Proceedings of the National Academy of Sciences. Get more great content like this delivered right to you! If not, well, fraud is on the table.. 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. Some scientists say this destroyed the dinosaurs; others believe they thrived during the period. By Nicole Karlis Senior Writer. With David Attenborough, Robert DePalma, Phillip Manning. [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.
