Robert DePalmashown here giving a talk at NASAs Goddard Space Flight Center in Aprilpublished a paper in December 2021 showing the asteroid that killed the dinosaurs struck Earth in the spring. 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. 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. 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.

Robert James DePalma, 71, a longtime Florida resident passed away Tuesday, May 12, 2020 at his residence in Fort Myers, FL. The paleontologist believed that this new information further supported the theory that an asteroid . 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. Robert DePalma (kottke.org) 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. A researcher claims that Robert DePalma published a faulty study in order to get ahead of her own work on the Tanis fossil site. But no one has found direct evidence of its lethal effects. Paleontologist accused of faking data in dino-killing asteroid paper The CretaceousPaleogene ("K-Pg" or "K-T") extinction event around 66 million years ago wiped out all non-avian dinosaurs and many other species. Fossilized snapshot of mass death found on North Dakota ranch 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. Tanis is a significant site because it appears to record the events from the first minutes until . DePalma, Robert | Department of Geology Fossilized snapshot of mass death found on North Dakota ranch It is not even clear whether the massive waves were able to traverse the entire Interior Seaway. though Robert DePalma's love of the dead and buried was anything but . 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. DePalma made major headlines in March 2019, when a splashy New Yorker story revealed the Tanis site to the world. New Evidence Shows Experts Have Dinosaurs' Extinction All Wrong 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. They've been presented at meetings in various ways with various associated extraordinary claims," a West Coast paleontologist said to The New Yorker. All of these factors seemed strange and confused the paleontologists. Please make a tax-deductible gift today. The extinction event caused by this impact began the Cenozoic, in which mammals - including humans - would eventually come to dominate life on Earth. Does fossil site record dino-killing impact? ", "Tanis exhibits a depositional scenario that was unusual in being highly conducive to exceptional (largely three dimensional) preservation of many articulated carcasses (Konservat-Lagersttte). The event included waves with at least 10 meters run-up height (the vertical distance a wave travels after it reaches land). Credit.

The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth. 01/05/2021. Paleontologist Accused of Making Up Data on Dinosaur-Killing Asteroid 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 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. .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.

Robert DePalma is a paleontologist who holds the lease to the Tanis site and controls access to it.. A bad day for dinosaurs was the subject of an engaging hour-and-a-half for both paleontologists and NASA researchers. If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. 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. [1]:pg.11 Key findings were presented in two conference papers in October 2017. Still, people's ardor for this group of reptiles is so passionate that 12% of Americans surveyed in an Ipsos poll would resurrect T. rexes and the rest of these mysterious creatures if it were possible.

Ultimately, both studies, which appeared in print within weeks of each other, were complementary and mutually reinforcing, he says. 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. Contributions to The Journal of Paleontological Sciences 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. 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.

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. DePalma and his colleagues have been working at Tanis since 2012. Even as a child, DePalma wondered what the Cretaceous was like. On 2 December, according to an email forwarded to Science, the editor handling DePalmas paper at Scientific Reports formally responded to During and Ahlberg for the first time, During says. Other papers describing the site and its fossils are in progress. "The thing we can do is determine the likelihood that it died the day the meteor struck. Scientists find fossil of dinosaur 'killed on day of asteroid strike' 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. 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. 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. 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.

[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. These fossils were delivered for research to the Field Museum of Natural History in Chicago. But just one dinosaur bone is discussed in the PNAS studyand it is mentioned in a supplement document rather than in the paper itself.

If they can provide the raw data, its just a sloppy paper. The response doesnt satisfy During and Ahlberg, who want the paper retracted. 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. However, because it is rare in any case for animals and plants to be fossilized, the fossil record leaves some major questions unanswered. 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. Something is fishy here, says Mauricio Barbi, a high energy physicist at the University of Regina who specializes in applying physics methods to paleontology.

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 . A thin layer of bone cells on sturgeons fins thickens each spring and thins in the fall, providing a kind of seasonal metronome; the x-rays revealed these layers were just beginning to thicken when the animals met their end, pointing to a springtime impact. No part of Durings paper had any bearing on the content of our study, DePalma says. 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.
