Scientists have discovered a dinosaur graveyard, formed by direct deposition of the impact of an asteroid that struck the Earth 66 million years ago – to destroy the giant.
Excavations at the site under the name Tanis in North Dakota shows the fossils that have been sprayed with red-hot fragments that fall from the sky at the time of the extinction event.
Deposits show evidence and the fact that it was filled up with water – a consequence of the huge tsunami in aqua style that was generated fatal blow.
Experts say the new find 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 excavations will now be published in the journal Proceedings of the National Academy of Sciences.
"Huddling mass of freshwater fish, terrestrial vertebrates, trees, branches, logs, sea ammonite and other sea creatures, everything was packed into the layer from the internal directional wave," said Robert DePalma from the University of Kansas.
"Tsunami would take at least 17 hours or more to reach the place of the crater, but seismic waves – and the next burst – have reached it in several tens of minutes."
In addition to fish, "cemetery" also contains evidence of dinosaurs, mammals and marine reptiles, who died in the aftermath of the asteroid impact.
Among the amazing residues, as reported, the remains of Triceratops and duck Sparrow & # 39; Inna hadrosaur.
The Chicxulub impact, caused by eight miles wide on the & # 39 object that crashed in the Gulf of Mexico, is believed to have caused the extinction of 75 percent of the animals and plants on Earth.

The researchers were able to date the site of fish skeletons and amber wood juice to a point about 66m years ago, when a giant space rock hit.
Fish have been found with a shock-induced debris imbedded in their gills mean that they would be breathed into fragments, which are filled with water around them.
Scientists have spent the last six years building a picture of how the animals came to die so quickly after the first blow.
