The discovery of fossilized fish can shed light on the day an asteroid hit Earth and killed the dinosaurs



The discovery of a fossilized fish could provide an insight into the day when an asteroid hit Earth and wiped dinosaurs from the planet 66 million years ago, according to a new study.

The "exquisitely preserved" fossils, some of which are fishes with hot glass in their gills, were found in North Dakota's Hell Creek Formation and are said to have formed after an asteroid that was crushed in Mexico and rained burning debris according to a press release from the University of Kansas on the floor.

The fossils provide the first "detailed snapshot of the terrible moments immediately after the impact of Chicxulub – the most catastrophic event that has made life on Earth known." The states of liberation.

The place seems to date 66 million years ago when a meteor hit the earth and killed almost all life on earth.

The impact destroyed about 75 percent of the Earth's wildlife at that time, including dinosaurs.

The fossilized creatures lived near a deep chiseled river, according to the publication. In the minutes after the impact, a rush of water was likely to create "the confused mass of freshwater fish, terrestrial animals, trees, branches, logs, marine ammonites, and other marine life," all stored in one shift in the discovered rock formation by Robert DePalma, graduate student in geology University of Kansas

The fish were "killed quite suddenly by the violence of this water," said the co-author of the study, David Burnham, taxidermist of vertebrate paleontology at Biodiversity Institute of the University of Kansas. Burnham said one of the fossilized fish had broken in half when he hit a tree.

The search for these hundreds of ancient fish fossils is even more significant because the fish are cartilaginous instead of bone and less prone to fossilization, Burnham said. Scientists are also discovering new species in the fossil record collection.

The planet was "inherited" from the impact of mammalian asteroids, Burnham said.

"We understood that bad things happened right after the impact, but no one has found that kind of evidence of guns," he said. "People said," We know that this explosion killed the dinosaurs, but why do not we have bodies everywhere? "Well, now we have bodies, they are not dinosaurs, but I think they will eventually be found."

The study will be published on Monday in the Proceedings of the National Academy of Sciences, according to the University of Kansas.
