New research released Friday captures a fossilized snapshot of the day nearly 66 million years ago when an asteroid smacked Earth, fire rained from the sky and the ground shook far worse than any modern earthquake.

It was the day that nearly all life on Earth went extinct, including the dinosaurs.


The researchers say they found evidence in North Dakota of the asteroid hit in Mexico, including fish with hot glass in their gills from flaming debris that showered back down on Earth. They also reported the discovery of charred trees, evidence of an inland tsunami and melted amber.

Separately, University of Amsterdam’s Jan Smit disclosed that he and his colleagues even found dinosaur footsteps from just before their demise.

Smit said the footprints — one from a plant-eating hadrosaur and the other of a meat eater, maybe a small Tyrannosaurus Rex — is “definite proof that the dinosaurs were alive and kicking at the time of impact … They were running around, chasing each other” when they were swamped.”

“This is the death blow preserved at one particular site. This is just spectacular,” said Purdue University geophysicist and impact expert Jay Melosh, who wasn’t part of the research but edited the paper released Friday by the journal Proceedings of the National Academy of Sciences.

Melosh called it the field’s “discovery of the century.” But other experts said while some of the work is fascinating, they have some serious concerns about the research, including the lack of access to this specific Hell Creek Formation fossil site for outside scientists.

Hell Creek — which spans Montana, both Dakotas and Wyoming — is a fossil treasure trove that includes numerous types of dinosaurs, mammals, reptiles and fish trapped in clay and stone from 65 to 70 million years ago.

Kirk Johnson , director of the Smithsonian National Museum of Natural History who also has studied the Hell Creek area for 38 years, said the work on the fish, the glass and trees “demonstrates some of the details of what happened on THE DAY. That’s all quite interesting and very valid stuff.”

But Johnson said because there is restricted access to the site, other scientists can’t confirm the research.

Smit said the restrictions were to protect the site from poachers.

Johnson also raised concerns about claims made by the main author, Robert DePalma, a University of Kansas doctoral student, that appeared in a New Yorkermagazine article published Friday but not in the scientific paper.

DePalma did not return an email or phone message seeking comment.

For decades, the massive asteroid crash that caused the Chicxulub crater in Mexico’s Yucatan Peninsula has been considered the likely cause of the mass extinction often called the “KT boundary” for the division between two geologic time periods. But some scientists have insisted that massive volcanic activity played a role. Johnson and Melosh said this helps prove the asteroid crash case.

There were only a few dinosaur fossils from that time, but the footsteps are most convincing, Smit said.

There was more than dinosaurs, he said. The site includes ant nests, wasp nests, fragile preserved leaves and fish that were caught in the act of dying. He said that soon after fish die they get swollen bellies and these fossils didn’t show swelling.

The researchers said the inland tsunami points to a massive earthquake generated by the asteroid crash, somewhere between a magnitude 10 and 11. That’s more than 350 times stronger than the 1906 San Francisco earthquake.

Purdue’s Melosh said as he read the study, he kept saying “wow, wow, what a discovery.”

The details coming out of this are “mind-blowing,” he said. (VOA)

Hosting the Olympics is an economic burden on host cities which mainly include construction delays, cost overruns, security issues, and environmental concerns.

Gone are those days when people, sports enthusiasts, and governments lined up to host the Olympics. Hosting the Olympics, once seemed to be an immensely prideful event, but it has now transformed into an economic burden. Host cities grapple with a plethora of problems which mainly include construction delays, cost overruns, security issues, and environmental concerns.

Tokyo Olympics 2020 Indian wrestler Ravi Kumar enter semi finals.

Indian wrestler Ravi Kumar (57kg) and Deepak Punia (86kg) enjoyed fruitful outings at the Tokyo Olympic Games as they secured semifinal berths in their respective weight categories at the Makuhari Messe on Wednesday.

On the opening day of the wrestling competition, Ravi Kumar defeated Bulgaria's Georgi Vangelov 14-4 on technical superiority to reach the last-four in the men's 57kg category, while compatriot Deepak Punia overcame China's Zushen Lin 6-3 on points to advance to the semifinals.

Ravi Kumar will take on Nurislam Sanayev of Kazakhstan in the last-four, while Punia will be up against David Morris Taylor of the USA.

Earlier, Ravi Kumar had won his opening-round bout by technical superiority against Colombia's Oscar Tigreros to secure a quarterfinal spot. Competing in the Round-of-16 bout against the Colombian wrestler, the 23-year-old Ravi Kumar, who is making his Olympic debut, showed no nerves as he dominated the bout to win by technical superiority (13-2).

Ravi Kumar landed attack after attack and went 13-2 up, winning the bout by technical superiority with minutes to spare. In wrestling, building up a 10-point lead over the opponent results in a victory by technical superiority.

India's 86kg freestyle wrestler Deepak Punia showed no signs of the niggle that had forced him to pull out of the Poland Open Ranking Series in Warsaw in June, as he defeated Nigeria's Ekerekeme Agiomor on technical superiority to secure a quarterfinal berth.

He got his Olympic campaign to a fine start as he was in control from the start of the bout and hardly ever allowed his Nigerian opponent any room to maneuver his moves, finally winning with a 12-1 on technical superiority.

Punia, who had also suffered an elbow injury just before the Games, was slow at the start but came into his own as the bout progressed, inflicting takedowns at regular intervals to earn points.

The Indian wrestler eased into a 4-1 lead at the break and extended his lead comfortably in the second period.

Punia, the silver medallist from the 2019 world wrestling championships, then set up a clash with China's Lin Zushen in the quarterfinals and defeated him 6-3.
