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. Three papers were published in 2021. Dont yet have access? Kansas University, via Agence France-Presse Getty Images The death scene from within an hour of the impact has been excavated at an unprecedented .

One Of Richest Fossil Resources In The World Crossed By Keystone - SDPB Discoveries shed new light on the day the dinosaurs died. Robert DePalma Obituary (2010) - Columbus, OH - The Columbus Dispatch This had initially been a seaway between separate continents, but it had narrowed in the late Cretaceous to become, in effect, a large inland extension to the Gulf of Mexico. After his team learned about Durings plan to submit a paper, DePalma says, one of his colleagues strongly advised During that the paper must at minimum acknowledge the teams earlier work and include DePalmas name as a co-author. Sir David Attenborough's Latest BBC Film To Unearth - Deadline The Tanis site was first identified in 2008 and has been the focus of fieldwork by paleontologist Robert DePalma since . Scientists may have found fragments of THE asteroid that wiped out the 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 day 66 million years ago when the reign of the dinosaurs ended and the rise of . Boca paleontologist Robert de Palma uncovers evidence of the day the dinosaurs diedand how it connects to homo sapiens. Dinosaurs' Last Spring: Groundbreaking Study Pinpoints Timing of THE DAY THE CRETACEOUS ENDED - Magzter It is not even clear whether the massive waves were able to traverse the entire Interior Seaway. Robert DePalma | KU Geology - University Of Kansas . 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. 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. Astonishment, skepticism greet fossils claimed to record dinosaur-killing asteroid impact. 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 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. [8] Following suspicions of manipulating data, a complained was lodged against DePalma with the University of Manchester. Using the same formula, the Chicxulub earthquakes may have released up to 1412 times as much energy as the Chile event. [5] Co-author Professor Phillip Manning, a specialist in fossil soft tissues,[19] described DePalma's working techniques at Tanis as "meticulous" and "borderline archaeological in his excavation approach". There was no advanced decay. Robert DePalma uncovers a preserved articulated body of a 65-million-year-old fish at Tanis. 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. The response doesnt satisfy During and Ahlberg, who want the paper retracted. TV scientist accused of FAKING data in a major dinosaur study It comprises two layers with sand and silt grading (coarse sands at the bottom, finer silt/clay particles at the top). Help News from Science publish trustworthy, high-impact stories about research and the people who shape it. Top editors give you the stories you want delivered right to your inbox each weekday. He declined to share details because the investigation is ongoing. DePalma did not respond to an email request for an interview. The situation was first reported by the publication Science last month. . The exceptional nature of the findings and conclusions have led some scientists to await further scrutiny by the scientific community before agreeing that the discoveries at Tanis have been correctly understood. How the dinosaurs died: New evidence In PBS documentary - The Ive done quite a few excavations by now, and this was the most phenomenal site Ive ever worked on, During says. Tanis: Fossil found of dinosaur killed in asteroid strike - BBC 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. The site, dubbed "Tanis," first underwent excavation in 2012, with DePalma and his team digging along a section known as the Hell Creek Formation (via Boredom Therapy). I dont believe that Curtis himself went to another lab, he was ill for many years, Sacasa says. 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. 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. 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 has not made public the raw, machine-produced data underlying his analyses. The study of these creatures is limited to the fossils they left behind and those provide an incomplete picture. It features what appear to be scanned printouts of manually typed tables containing the isotopic data from the fish fossils. "After a while, we decided it wasn't a good route to go down," he says. 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. . Michael Price is associatenews editor for Science, primarily covering anthropology, archaeology, and human evolution. TV Paleontologist Facing Backlash After Reportedly Faking Data Han var redan som barn fascinerad av ben. In December 2021, a team of paleontologists published data suggesting that the asteroid impact that ended the reign of dinosaurs could be pinned down to a season springtime, 66 million years agothanks to an analysis of fossilized fish remains at a famous site in North . The 1960 Valdivia Chile earthquake was the most powerful ever recorded, estimated at magnitude 9.4 to 9.6. If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. 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. Tanis is a significant site because it appears to record the events from the first minutes until a few hours after the impact of the giant Chicxulub asteroid in extreme detail. A fossil site in North Dakota records a stunningly detailed picture of the devastation minutes after an asteroid slammed into Earth about 66 million years ago, a group of paleontologists argue in a paper due out this week. Of his discovery, DePalma said, "It's like finding the Holy Grail clutched in the . As of April 2019, reported findings include: The hundreds of fish remains are distributed by size, and generally show evidence of tetany (a body posture related to suffocation in fish), suggesting strongly that they were all killed indiscriminately by a common suffocating cause that affected the entire population. [citation needed], At the time of the Chicxulub impact, the present-day North American continent was still forming. By Robert Sanders, Media relations | March 29, 2019. Still, when During submitted her manuscript to Nature on 22 June 2021, she listed DePalma as the studys second author. 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. 66 million-year-old deathbed linked to dinosaur-killing meteor Both papers made their conclusions based on analysis of fish remains at the Tanis fossil site in North Dakota. When asked for more information on the situation on January 3, a spokesperson for Scientific Reports said there were no updates.
