December 10, 2021 Source: . View Obituary & Service Information I dont believe that Curtis himself went to another lab, he was ill for many years, Sacasa says. Bob was born in Newark, NJ on December 26, 1948 to the late James and Rose DePalma. 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 . 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 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. The fact that spherules were found in the fishes gills suggested the animals died in the minutes to hours after the impact. 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. Top editors give you the stories you want delivered right to your inbox each weekday. 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. Nicklas also indicates that "in 2012 we decided to try to find an academic paleontologist who had the necessary interest, time, and the ability to excavate the site A good friend of ours, Ronnie Frithiof, recommended Robert DePalma. 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. 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. 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. In fact, there are probably dinosaur types that still remain unidentified, reported Smithsonian Magazine. Robert A. DePalma, a paleontologist at the Palm Beach Museum of Natural History and a graduate student at the University of Kansas. He has mined a fossil site in North Dakota secretly for . The findings are the work of paleontologist Robert DePalma, who has previously attracted controversy.

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. The site was systematically excavated by Robert DePalma over several years beginning in 2012, working in near total secrecy. 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 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. The Tanis site was first identified in 2008 and has been the focus of fieldwork by paleontologist Robert DePalma since . This program was also aired as "Dinosaur Apocalypse: The Last Day" on PBS Nova starting 11 May 2022.[9][32]. Both papers made their conclusions based on analysis of fish remains at the Tanis fossil site in North Dakota. "He could have stumbled on something amazing, but he has a reputation for making a lot out of a little.". This dinosaur, a giant reptilian, lived during the Early Cretaceous period in oceans. A version of this story appeared in Science, Vol 378, Issue 6625. 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. 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. Many theories exist about why the dinosaurs disappeared from the Earth. Bde hans far och hans farfars bror var kirurger i Florida. Cochran says the format of the isotopic data does not appear unusual. 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. . It's at a North Dakota cattle ranch, some 2,000 miles (3,220 km) away. 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. According to Science, DePalma was incorrect in 2015 when he believed he discovered a bone from a new type of dinosaur. Michael Price is associatenews editor for Science, primarily covering anthropology, archaeology, and human evolution. [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]. [25] The last was published in December in Scientific Reports. The excavated pointbar and event deposits show that the point bar had been exposed to the air for a considerable time, with evidence of habitation and filled burrows, before an abrupt, turbulent, high energy event filled these burrows and laid down the deposits. It feels like a case of the dog ate my homework, and I dont think the relatives of Curtis McKinney deserve this, During told Gizmodo. 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. Your tax-deductible contribution plays a critical role in sustaining this effort. 2023 American Association for the Advancement of Science. Perhaps no animal, living or dead, has captivated the world in the way that dinosaurs have. The site, after all, does not conclusively prove that the asteroid's impact actually caused the dinosaurs' demise, reported Science. After trying to discuss the matter with editors at Scientific Reports for nearly a year, During recently decided to make her suspicions public. If I were the editor, I would retract the paper unless [the raw data] were produced posthaste, he says. "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. DePalma did not respond to a Gizmodo request for comment, but he told Science, We absolutely would not, and have not ever, fabricated data and/or samples to fit this or another teams results., On December 9, a note was added to DePalmas paper on the Scientific Reports website. They seem to have left the raw data out of the manuscript deliberately, he says. If they can provide the raw data, its just a sloppy paper. [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]. DePalma holds the lease to the Tanis site, which sits on private land, and controls access to it. Petrified fish with glass spheres, called ejecta, were also at the site. 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.

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. .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. The site lacked the fine sediment layers he was initially looking for. 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. Please make a tax-deductible gift today. This whole site is the KT boundary We have the whole KT event preserved in these sediments. . When one paleontologist began excavating a dig site in the mountains of North Dakota, he soon discovered new dinosaur evidence that may change history. "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. [1]:p.8192 The river flowed Eastward (other than impact driven waves),[1]:p.8192 with inland being to the West; Tanis itself was therefore in an ancient river valley close to the Westward shore of the Interior Seaway. 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 study of these creatures is limited to the fossils they left behind and those provide an incomplete picture. 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. Get more great content like this delivered right to you! "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. Such a conclusion might provide the best evidence yet that at least some dinosaurs were alive to witness the asteroid impact. though Robert DePalma's love of the dead and buried was anything but . The Chicxulub impact is believed to have triggered earthquakes estimated at magnitude 10 11.5,[1]:p.8 releasing up to 4000 times the energy of the Tohoku quake.Note 1 Co-author Mark Richards, a professor of earth sciences focusing on dynamic earth crust processes[16] suggests that the resulting seiche waves would have been approximately 10100m (33328ft) high in the Western Interior Seaway near Tanis[1]:p.8 and credibly, could have created the 10 11 m (33 36 feet) high water movements evidenced inland at the site; the time taken by the seismic waves to reach the region and cause earthquakes almost exactly matched the flight time of the microtektites found at the site. Asked where McKinney conducted his isotopic analyses, DePalma did not provide an answer. But there were other inconsistencies at the excavation site the fossils they found seemed out of place, with some skeletons located in vertical positions. While DePalma corrected his claim, his reputation still took a hit. The raw data are missing, he says, because the scientist who ran the analyses died years prior to the papers publication, and DePalma has been unable to recover them from his deceased collaborators laboratory.
