Prehistoric "Killing Fields" is full of dinosaur fossils "prove meteorite theory '- World News


Beginning of the End raced in without warning 66 million years ago.

The impact caused a tsunami and a hail of deadly rain of glass, and then choked in the dust of the Earth's atmosphere in the version of events is believed to have marked the end of the world for the dinosaurs.

The leading theory, the board of one of the largest and most fearsome species ever to walk the Earth came to an end after the impact of an asteroid or comet.

But the findings leading scientists in the prehistoric "killing field" may be the best evidence yet that massive meteor set off a sequence of events that led to the mass extinction of the dinosaurs, according to Berkeley News.

The six-year-long time digging in the United States have found that there may be the holy grail of resources.

Soon to be published article will show how fossils remains- including Triceratops- tell the story of how, in the last mass extinction Earth has begun for a few minutes in the meteorite.

It is estimated that 66 million years later, scientists painstakingly digging through the formation of Hell Creek, in what is now known as North Dakota, to find evidence that could explain the events that led to the end of the reign of the dinosaurs.

On-site at the center of an internal US state known as exposure Tanis, paleontologists may have found evidence of many looking for.

They are constantly discovered fossils of dinosaur collection, as well as birds and mammals.

It is reported that they have found the bones of large marine reptiles – the extinct aquatic lizards called mosasaurs – and partial carcass triceratops.

They found a snail as marine cephalopod called ammonite and marine microorganisms called dinoflagellates.

Among the remains of the fish were stacked one on Other- proved among the most important finds – along with burned tree trunks and branches, mammals and insects.

They were discovered in the last six years, a paleontologist Robert DePalma, who said Berkeley news this week that he suspected since the first excavation season in 2013 that it was "Killing Fields" tells the story of the impact.

He believes that this is the first "mass death of a bunch of" major life forms ever found in the case of a mass extinction of the dinosaurs in the effects are believed to ultimately lead to the disappearance of all terrestrial dinosaurs.

Scientists say that the influence of the late Cretaceous period, destroyed 75 percent of life on Earth.

DePalma, who & # 39 is the curator of paleontology at the Palm Beach Museum of Natural History, said the discovery was a famous place of mass mortality associated with «K-T boundary."

The term refers to the elimination of the effects of the asteroid impact at the end of the Cretaceous period.

"In no other KT boundary section in the world can you find such a collection consisting of a large number of species of organisms, different ages and different stages of life, all of whom died at the same time, on the same day," he said Berkeley News.

DePalma was reportedly about to publish a paper on the results of his team in the journal Proceedings of the National Academy of Sciences, with his team leading experts, including two from the University of California at Berkeley, the geologists.

The document reportedly provide evidence connected the dinosaur graveyard with an asteroid or comet striking out the Yucatan Peninsula in Mexico.

Impact 66 million years ago is widely believed, it is doomsday for dinosaurs, but experts around the world are still investigating the exact causes of mass extinction.

What is known is that the impact created a huge crater called Chicxulub on the ocean floor, which caused a massive tsunami and inflicted deadly dust cloud of asteroids and evaporate rocks, to decode the earth's atmosphere.

This is what the death cloud that is believed to have finally secured the fate of the dinosaurs last mass extinction Earth, eventually destroy all the dinosaurs that were not killed in the initial impact and tsunami.

But the place where was found a dinosaur graveyard was thousands of miles from the point of impact, and far inland.

Scientists have spent the last six years building a picture of how the animals came to die so quickly after the first blow.

UC Berkeley professor emeritus of Earth and Planetary Sciences, and Professor of Earth and Space Sciences at the University of Washington, Mark Richards, described the site in Berkeley News, as "as a museum in the late Cretaceous period in a layer of a meter, and -a half thickness".

The expert, who first floated 40 years ago, the theory with his father that a comet or asteroid caused the mass extinction was a consultant on the study.

University of California at Berkeley professor Walter Alvarez was among the scholars were asked to investigate whether the tiny glass beads found among the site were "tektites."

Fish at the site have been found preserved that scientists believe to be tektites – glass beads formed in the atmosphere from the rock melts under the influence.

A couple asked to examine samples of the wave, and beads, to investigate whether there is deposited and buried on the site of a tsunami fish.

But Richards Alvarez came to the conclusion that the tsunami could not run aground and buried fish – who would have reached the place where they were found is about 10-12 hours after exposure (3,000 km 1,860 miles) away.

tsunami theory does not make sense, they said Berkeley News, because Tektites be poured within 45 minutes to an hour of exposure.

They would not be able to create a mud hole when the seabed was not already exposed.

Experts conclude that the fate of the fish was sealed in a sequence of seismic waves arriving within 10 minutes of exposure, in equivalent quantities violent earthquakes 10 to 11.

They told the news site that would shake created Seiche – standing wave- depth.

They compared seiche to the water squelching in the bath at the time of the earthquake.

They explained that a large earthquake can be sent seiche in closed waters epic distance away.

This is what happened after the devastating magnitude 9 Tohoku earthquake in Japan in 2011, which created a six-foot-high seiche 30 minutes in a Norwegian fjord 8,000km (5,000 miles) from the hotel, they said Berkeley News.

Scientists believe that as the water splashed in the country, tektites are falling from the sky, pelting like tiny bullets at terminal speeds up to 200 miles per hour in the rain garbage killing living beings in their ways.

Dutch retired professor of sedimentary geology and the world's leading expert tektitic Jan Smit said Berkeley News were found glass beads perfectly preserved in amber.

Smit said that the buried body of Triceratops and duck Sparrow & # 39; Inna hadrosaur turned, without a doubt, the dinosaurs still walked the Earth at the moment of impact is thought to have caused the mass extinction.

But DePalma said Berkeley News really "big break" came when Richards found that seismic waves that come inland arrived around the same time as deadly rain of glass beads, creating a unique burial far inland.

His work will be reported in detail the theory that at least two huge seiche 20 minutes apart devastated the land, leaving the sediment covering the fossils, scientists have spent the last six years uncovereing.

Layers of clay minerals covering compositions comprise a metal rare on Earth.

But as Alavarez and his father found in 1979, Iridium is common in asteroids and comets.

The study will be speaking the same material covers the deposits covering the fossils in the formation of Hell Creek.

All these discoveries are reported to lead to single out one paper thrilling conclusion: that the dying dinosaurs 66 million years ago in Hell Creek Formation was laid down in a few minutes – and caused the asteroid.
