Washington • New studies published on Friday capture a fossilized photo of the day before almost 66 million years ago when the asteroid hit the Earth, the fire rained from the sky and the earth rocked far worse than any modern earthquake
North Dakota for the asteroid struck in Mexico, including a hot-swirled fish in their gills from flaming debris that came back to Earth. They also reported the discovery of charred trees, proof of a tsunami in the interior and molten amber.
Separately, Jan Smith of the University of Amsterdam revealed that he and his colleagues even found steps from the dinosaurs just before their death. prints ̵
"This is a deadly blow on a particular site. It is just spectacular, "said Purvey University geographer and impact expert Jay Melos, who was not part of the study, but edited the document, and Friday called" The Discovery of the Century "by the journal" Collections of the National Academy of Sciences " But other experts say that although some of the work is charming, they have some serious concerns about research, including the lack of access to this particular Hell Creek Formation site for external scientists Hell Creek – which covers Montana as Dakota, t and Wyoming – is a fossil treasure that includes many species of dinosaurs, mammals, reptiles, and fish caught in clay and stone mud 65-70 million years ago
Kirk Johnson, director of the Smithsonian National Museum of Natural History, has also been studying the Helen Gulf region for 38 years, saying that work on fish, glass and trees "shows some of the details of what happened on the Day. This is very interesting and very valid stuff. "But Johnson said that since there is limited access to the site, other scientists can not confirm the study.Smith said restrictions are to protect the site from poachers
Johnson also voiced concerns about the claims of the lead author, Robert Depalma , a PhD student from the University of Kansas, who appears in a New Yorker article published on Friday but not in a scientific paper.
For decades, the massive crash of the University of Kansas has failed to return an e-mail or telephone message requesting comment. the asteroids that caused the Chicxulub crater in the Yucatan Peninsula, is considered to be the likely cause of mass extinction, often referred to as the "KT boundary" for division between two geological periods, but some scientists insist that a huge volcanic activity plays a role. prove the case of the asteroid catastrophe
Since then there have been only a few fossils of dinosaurs, but the footsteps are the most convincing, Smith said. The site includes nests of ants, bottom nests, fragile preserved leaves and fish that were caught in dying. He said that soon after the fish died, they got swollen stomachs and these fossils did not show swelling.
Researchers say the land tsunami indicates a massive earthquake generated by the asteroid catastrophe somewhere between magnitude 10 and 11. This is more than 350 times stronger than the 1906 earthquake in San Francisco
