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. 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. 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. Please make a tax-deductible gift today. The site, after all, does not conclusively prove that the asteroid's impact actually caused the dinosaurs' demise, reported Science. [17] This would resolve conflicting evidence that huge water movements had occurred in the Hell Creek region near Tanis much less than an hour after impact, although the first megatsunamis from the impact zone could not have arrived at the site for almost a full day. Scientists find fossil of dinosaur 'killed on day of asteroid strike' AAAS is a partner of HINARI, AGORA, OARE, CHORUS, CLOCKSS, CrossRef and COUNTER. 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. "I just hope this hasn't been oversensationalized.". How we reported a controversial story about the day the dinosaurs died 66 million-year-old deathbed linked to dinosaur-killing meteor Your tax-deductible contribution plays a critical role in sustaining this effort. 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. Appropriate editorial action will be taken once this matter is resolved.. 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. Help News from Science publish trustworthy, high-impact stories about research and the people who shape it. [5] The fish were not bottom feeders. Isaac Schultz. However, because it is rare in any case for animals and plants to be fossilized, the fossil record leaves some major questions unanswered. [20] The sediment appeared to have liquefied and covered the deposited biota, then quickly solidified, preserving much of the contents in three dimensions. One Of Richest Fossil Resources In The World Crossed By Keystone - SDPB 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. "It saddens me that folks are so quick to knock a study," he says. Could this provide evidence to the theory that an asteroid did indeed cause the mass extinction of the dinosaurs? Last modified on Fri 8 Apr 2022 11.20 EDT. The paleontologist believed that this new information further supported the theory that an asteroid . Ive done quite a few excavations by now, and this was the most phenomenal site Ive ever worked on, During says. Even as a child, DePalma wondered what the Cretaceous was like. Others defend DePalma, like his co-author, Mark Richards, a geophysicist at the University of California, Berkeley. THE DAY THE CRETACEOUS ENDED - Magzter Paleontologist Robert DePalma Presents in NASA Goddard Colloquium on When we look at the preservation of the leg and the skin around the articulated bones, we're talking on the day of impact or right before. [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. A bad day for dinosaurs was the subject of an engaging hour-and-a-half for both paleontologists and NASA researchers. 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 most recent mass extinction event. The CretaceousPaleogene ("K-Pg" or "K-T") extinction event around 66 million years ago wiped out all non-avian dinosaurs and many other species. This further evidences the violent nature of the event. A field assistant, Rudy Pascucci, left, and the paleontologist Robert DePalma, right, at DePalma's dig site. 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. According to The New Yorker, DePalma also sports some off-putting paleontology practices, like keeping his discovery secret for so long and limiting other scientists' access to the site. Fragment of the asteroid that killed off the dinosaurs may have been 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. In June 2021, paleontologist Melanie During submitted a manuscript to Nature that she suspected might create a minor scientific sensation. All rights reserved. Another question about dinosaurs is what caused their extinction and there are many theories about that, too. Taylor Mickal/NASA. Retaliation is also prohibited by university policy. 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. With Gizmodos Molly Taft | Techmodo. [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.

A New Look at the Day the Dinosaurs Were Extinguished Bottom left, micro-CT image showing cutaway of clay-altered ejecta spherule with internal core of unaltered impact glass. During the long process of discussing these options they decided to submit their paper, he says. In December 2021, DePalma and his colleagues published an important paper . It is truly a magnificent site surely one of the best sites ever found for telling just what happened on the day of the impact. Could it be a comet, asteroid, or meteor that crashed into the planet, and the reverberations ended the reign of the dinosaurs? As a part of the settlement, the Sacklers will have immunity against any and all future civil litigation. The deathbed created within an hour of the impact has been excavated at an unprecedented fossil site in North Dakota. 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. Miami Dade does not have an operational mass spectrometer, suggesting McKinney would have had to perform the isotope analyses underlying the paper at another facility. Until a few years ago, some researchers had suspected the last dinosaurs vanished thousands of years before the catastrophe. 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. [5] Analysis of early samples showed that the microtektites at Tanis were almost identical to those found at the Mexican impact site, and were likely to be primary deposits (directly from the impact) and not reworked (moved from their original location by later geological processes).[1]. 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. If I were the editor, I would retract the paper unless [the raw data] were produced posthaste, he says. Could NASA's Electric Airplane Make Aviation More Sustainable? They've been presented at meetings in various ways with various associated extraordinary claims," a West Coast paleontologist said to The New Yorker. Robert DEPALMA, Postgraduate Researcher | Cited by 253 | of The University of Manchester, Manchester | Read 18 publications | Contact Robert DEPALMA Additional fossils, including this beautifully preserved fish tail, have been found at the Tanis site in North Dakota. Help News from Science publish trustworthy, high-impact stories about research and the people who shape it. High impact paleontology - Medium The first documents a turtle fossil found at Tanis, killed by impalement by a tree branch, and found in the upper of two units of surge deposit, bracketed by ejecta. She also removed DePalma as an author from her own manuscript, then under review at Nature. Robert DePalma made headlines again in 2021 with the discovery of a leg from a Thescelosaurus dinosaur at Tanis, reported The Washington Post. Perhaps no animal, living or dead, has captivated the world in the way that dinosaurs have. Robert James DePalma, 71, a longtime Florida resident passed away Tuesday, May 12, 2020 at his residence in Fort Myers, FL. TV scientist accused of FAKING data in a major dinosaur study 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. In the early 1980s, the discovery of a clay layer rich in iridium, an element found in meteorites, at the very end of the rock record of the Cretaceous at sites around the world led researchers to link an asteroid to the End Cretaceous mass extinction. "The thing we can do is determine the likelihood that it died the day the meteor struck. 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. Discoveries shed new light on the day the dinosaurs died. 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. 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. Images: Top right, Robert DePalma and Peter Larson conduct field research in Tanis. 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. ^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. New Winged Dinosaur May Have Used Its Feathers to Pin Down Prey [25] The last was published in December in Scientific Reports. 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 . 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 DePalma: We know there would have been a tremendous air blast from the impact and probably a loud roaring noise accompanied with that similar to standing next to a 747 jet on the runway. "I hope this is all legitI'm just not 100% convinced yet," says Thomas Tobin, a geologist at the University of Alabama in Tuscaloosa. If Tanis is all it is claimed to be, that debateand many others about this momentous day in Earth's historymay be over. 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. 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.. The situation was first reported by the publication Science last month. 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 . All rights reserved. At Tanis, unlike any other known Lagersttte site, it appears freak circumstances allowed for the preservation of exquisite, moment-by-moment details caused by the impact event. DePalma's dinosaur study, published in Scientific Reports in December 2021, . The 1960 Valdivia Chile earthquake was the most powerful ever recorded, estimated at magnitude 9.4 to 9.6. 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. 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. Both papers studied 66-million-year-old paddlefish jawbones and sturgeon fin spines from Tanis. In the early 1980s, the discovery of a clay layer rich in iridium, an element found in meteorites, at the very end of the rock record of the Cretaceous at sites around the world led researchers to link an asteroid to the End Cretaceous mass extinction. He has mined a fossil site in North Dakota secretly for . 2023 American Association for the Advancement of Science. But it's not at the asteroid's crash site. The Crude Life Interview: Robert Depalma, paleontologist 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.. Robert DePalma made headlines again in 2021 with the discovery of a leg from a Thescelosaurus dinosaur at Tanis, reported The Washington Post. 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. 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. It features what appear to be scanned printouts of manually typed tables containing the isotopic data from the fish fossils. Sir David Attenborough's Latest BBC Film To Unearth - Deadline It's at a North Dakota cattle ranch, some 2,000 miles (3,220 km) away. 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. . It could be just one factor in a series of environmental events that led to their extinction. though Robert DePalma's love of the dead and buried was anything but . [8] Following suspicions of manipulating data, a complained was lodged against DePalma with the University of Manchester. During described the findings in her 2018 masters thesis, a copy of which she shared with DePalma in February 2019. This directly applies to today. Searching in the hills of North Dakota, palaeontologist Robert DePalma makes an incredible . Contributions to The Journal of Paleontological Sciences During obtained extremely high-resolution x-ray images of the fossils at the European Synchrotron Radiation Facility in Grenoble, France. DePalma and his colleagues have been working at Tanis since 2012. DePalma holds the lease to the Tanis site, which sits on private land, and controls access to it. No part of Durings paper had any bearing on the content of our study, DePalma says. 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.. DEPALMA Robert Michael DePalma Jr. of Columbus, Ohio passed away unexpectedly February 15, 2010 at the age of 26 years. From the size of the deposits beneath the flood debris, the Tanis River was a "deep and large" river with a point bar that was towards the larger size found in Hell's Creek, suggesting a river tens or hundreds of meters wide. All of these factors seemed strange and confused the paleontologists. The paleontologist who found extinction day fossils teases - Salon 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. But the fossils also held clues to the season of the catastrophe, During found. 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 . "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. Scarred Duckbill Dinosaur Escaped T. Rex Attack - National Geographic Dinosaurs' Last Spring: Groundbreaking Study Pinpoints Timing of Boca paleontologist Robert de Palma uncovers evidence of the day the dinosaurs diedand how it connects to homo sapiens. A North Dakota Excavation Had One Paleontologist Rethinking The ", "Tanis exhibits a depositional scenario that was unusual in being highly conducive to exceptional (largely three dimensional) preservation of many articulated carcasses (Konservat-Lagersttte). Robert DePalma is a paleontologist who holds the lease to the Tanis site and controls access to it. This is misconduct, During wrote in an email to Gizmodo. 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. By looking through this window into the past, we can apply these lessons to today. Stunning discovery offers glimpse of minutes following 'dinosaur-killer [8] The site continues to be explored. This is not a case of he said, she said. This is also not a case of stealing someones ideas. Did the Dinosaurs Die on a Pleasant North Dakota Spring Day?

Subscribe to News from Science for full access to breaking news and analysis on research and science policy. Credit. Ahlberg shared her concerns. Fossils may capture the day the dinosaurs died. Here's what - Science .mw-parser-output .citation{word-wrap:break-word}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}^Note 1 This section is drawn from the original 2019 paper[1] and its supplementary materials,[4] which describe the site in detail. He suggested that the impact caused huge seiches (or tsunamis), which allowed the mosasaur tooth to travel from fresh water to that spot, along with freshwater sturgeon that may have choked on glassy pieces from the collision, reported Science. If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. Paleontologist Robert DePalma believes he has found evidence of the first minutes to hours of that catastrophic event. Study leader Robert DePalma conducts field research at the Tanis site. 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. Paleontologist accused of faking data in dino-killing asteroid paper [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. There is still much unknown about these prehistoric animals. 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. In lieu of controversial New Yorker article, UCD Professor weighs in on It reads: Editors Note: Readers are alerted that the reliability of data presented in this manuscript is currently in question. [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. May 9, 2022 at 7:00 a.m. EDT. As detailed by Science, the isotopic data in DePalmas paper was collected by archaeologist Curtis McKinney, who died in 2017. Petrified fish with glass spheres, called ejecta, were also at the site. Some scientists were not happy with this proposal.

The deposit itself is about 1.3m thick, sharply overlaying the point bar, in a drape-like manner. Dont yet have access? While DePalma corrected his claim, his reputation still took a hit. 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. Hell Creek evidence pinpoints month of dinosaur extinction - Earth & Sky 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. 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. Point bars are common in mature or meandering streams. A wealth of other evidence has persuaded most researchers that the impact played some role in the extinctions. New Evidence Shows Experts Have Dinosaurs' Extinction All Wrong The 2023 Complete Python Certification Bootcamp Bundle, What Is Carbon Capture?
