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. [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. . Gizmodo covered the research at the time. Fossils from dinosaurs and other animals from thousands of years before the asteroid impact are very hard to come by, leading some to believe . How to Know If the Heat Is Making You Sick. 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. How the dinosaurs died: New evidence In PBS documentary - The The death scene from within an hour of the impact has been excavated at an unprecedented . DePalma, now a Ph.D. student at the University of Manchester, vehemently denies any wrongdoing. Ritchie Hall | Earth, Energy & Environment Center 1414 Naismith Drive, Room 254 Lawrence, KS 66045 geology@ku.edu 785-864-4974 Abstract - Nasa Th "After a while, we decided it wasn't a good route to go down," he says. The chief editor of Scientific Reports, Rafal Marszalek, says the journal is aware of concerns with the paper and is looking into them. 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. How we reported a controversial story about the day the dinosaurs died 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. Tanis is a site of paleontological interest in southwestern North Dakota, United States. Dinosaurs have been dead for so long,'" DePalma told The Washington Post. New Evidence Shows Experts Have Dinosaurs' Extinction All Wrong 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 . Manning confirms rumors that the study was initially submitted to a journal with a higher impact factor before it was accepted at PNAS. Something is fishy here, says Mauricio Barbi, a high energy physicist at the University of Regina who specializes in applying physics methods to paleontology. Raising the Bar: Chocolate's History, Art, and Taste With Sophia Contreras Rea Boca paleontologist Robert de Palma uncovers evidence of the day the dinosaurs diedand how it connects to homo sapiens. In June 2021, paleontologist Melanie During submitted a . This dinosaur, a giant reptilian, lived during the Early Cretaceous period in oceans. The extinction event caused by this impact began the Cenozoic, in which mammals - including humans - would eventually come to dominate life on Earth. A researcher claims that Robert DePalma published a faulty study in order to get ahead of her own work on the Tanis fossil site. The study of these creatures is limited to the fossils they left behind and those provide an incomplete picture. Get more great content like this delivered right to you! Forum News Service, provided DEPALMA Robert Michael DePalma Jr. of Columbus, Ohio passed away unexpectedly February 15, 2010 at the age of 26 years. 03/30/2022. A version of this story appeared in Science, Vol 378, Issue 6625. Robert DePalma is a paleontologist who holds the lease to the Tanis site and controls access to it. 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. "I just hope this hasn't been oversensationalized.". Robert DePalma uncovers a preserved articulated body of a 65-million-year-old fish at Tanis. Bottom left, micro-CT image showing cutaway of clay-altered ejecta spherule with internal core of unaltered impact glass. December 10, 2021 Source: . The email, which came after Science started to inquire about the case, says their concerns remain under investigation. He is survived by his loving wife,. Bob was born in Newark, NJ on December 26, 1948 to the late James and Rose DePalma. The story of the discoveries is revealed in a new documentary called "Dinosaur Apocalypse," which features naturalist Sir David Attenborough and paleontologist Robert DePalma and airs . While some lived near a river, lake, lagoon, or another place where sediment was found, many thrived in other habitats. They seem to have left the raw data out of the manuscript deliberately, he says. The site was systematically excavated by Robert DePalma over several years beginning in 2012, working in near total secrecy. But others question DePalma's interpretations. Fossils may capture the day the dinosaurs died. Here's what - Science Even as a child, DePalma wondered what the Cretaceous was like. [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. Tanis is on private land; DePalma holds the lease to the site and controls access to it. Douglas Preston's writing about the discovery lauds it as one of the . They had breathed in early debris that fell into water, in the seconds or minutes before death. 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. Your tax-deductible contribution plays a critical role in sustaining this effort. 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. 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. TV scientist accused of FAKING data in a major dinosaur study 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. What we do know is that during the Jurassic period, great global upheaval occurred with increases in temperature, surging sea levels, and less humidity. Robert A. DePalma, a paleontologist at the Palm Beach Museum of Natural History and a graduate student at the University of Kansas. Over the next 2 years, During says she made repeated attempts to discuss authorship with DePalma, but he declined to join her paper. "I'm suspicious of the findings. Could this provide evidence to the theory that an asteroid did indeed cause the mass extinction of the dinosaurs? Though this might seem like a large number, a study intheProceedings of the National Academy of Sciencessaidit's possible that more than 1,800 different kinds of dinosaurs walked the earth. The Byte reports that the amber was found 2,000 miles away from the asteroid crater off the coast of Mexico believed to be . An imagined dinosaur scene just after the asteroid strike that caused a mass extinction, from . Science journalism's obligation to truth. The response doesnt satisfy During and Ahlberg, who want the paper retracted. 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. 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. They've been presented at meetings in various ways with various associated extraordinary claims," a West Coast paleontologist said to The New Yorker. Paleontologist Accused of Making Up Data on Dinosaur-Killing Asteroid Was it a fierce volcanic eruption that toppled these creatures? 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. 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 . Robert DePalma published a study in December 2021 that said the dinosaurs went extinct in the springtime - but a former colleague has alleged that it's based on fake data. A 2-centimeter-thick layer rich in telltale iridium caps the deposit. 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. A researcher claims that Robert DePalma published a faulty study in order to get ahead of her own work on the Tanis fossil site. Robert DePalma. Paleontologist Robert DePalma believes he has found evidence of the first minutes to hours of that catastrophic event. 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. DePalma gave the name Tanis to both the site and the river. At the site, called Tanis, the researchers say they have discovered the chaotic debris left when tsunamilike waves surged up a river valley. Both papers made their conclusions based on analysis of fish remains at the Tanis fossil site in North Dakota. In lieu of controversial New Yorker article, UCD Professor weighs in on It needs to be explained. Stunning discovery offers glimpse of minutes following 'dinosaur-killer A newly discovered winged raptor may have belonged to a lineage of dinosaurs that grew large after . 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. 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. The skull of the scarred Edmontosaurus also showed signs of trauma, and from the size and shape of the marks on the bone, Rothschild and fellow co-author Robert DePalma, a paleontologist at the . He says the study published in Scientific Reports began long before During became interested in the topic and was published after extended discussions over publishing a joint paper went nowhere. He reportedly helps fund his fieldwork by selling replicas of his finds to private collectors. 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 DAY THE CRETACEOUS ENDED - Magzter This impact, which struck the Gulf of Mexico 66.043 million years ago, wiped out all non-avian dinosaurs and many other species (the so-called "K-Pg" or "K-T" extinction). FAU's Robert DePalma, senior author and an adjunct professor in the Department of Geosciences, Charles E. Schmidt College of Science, and a doctoral student at the . [2], A paper documenting Tanis was released as a prepublication on 1 April 2019. The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth. In December 2021, a team of paleontologists published data . The CretaceousPaleogene ("K-Pg" or "K-T") extinction event around 66 million years ago wiped out all non-avian dinosaurs and many other species. 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.. During and DePalma spent 10 days in the field together, unearthing fossils of several paddlefish and species closely related to modern sturgeon called acipenseriformes. 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. DePalma has not made public the raw, machine-produced data underlying his analyses. [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]. The Final Day with David Attenborough (TV Movie 2022) - IMDb "I hope this is all legit I'm just not 100% convinced yet," said Thomas Tobin, a geologist at the University of Alabama in Tuscaloosa. [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. Such Konservat-Lagersttten are rare because they require special depositional circumstances. Using the same formula, the Chicxulub earthquakes may have released up to 1412 times as much energy as the Chile 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. 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. Also, there is little evidence on the detailed effects of the event on Earth and its biosphere. 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. [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. After trying to discuss the matter with editors at Scientific Reports for nearly a year, During recently decided to make her suspicions public. 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. Did the Dinosaurs Die on a Pleasant North Dakota Spring Day? Episode . . Robert DePalma made headlines again in 2021 with the discovery of a leg from a Thescelosaurus dinosaur at Tanis, reported The Washington Post. DePalma may also flout some norms of paleontology, according to The New Yorker, by retaining rights to control his specimens even after they have been incorporated into university and museum collections. 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. DePalma characterizes their interactions differently. JPS.C.2021.0002: The Paleontology, Geology and Taphonomy of the Tooth Draw Deposit; Hell Creek Formation (Maastrictian), Butte County, South Dakota. Based on the . 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. 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. 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. The Hell Creek Formation is a well-known and much-studied fossil-bearing formation (geological region) of mostly Upper Cretaceous and some lower Paleocene rock, that stretches across portions of Montana, North Dakota, South Dakota, and Wyoming in North America.
