New Research Reveals What Happened on Earth the First Day the Dinosaurs Died – Interesting Engineering

Published

For years scientists have blamed an asteroid for wiping out the dinosaurs, setting off wildfires and tsunamis and sending so much sulfur into the atmosphere that sunlight was obstructed upon impact. 

Now scientists have real evidence to back up that assessment thanks to researchers at The University of Texas. They found hard evidence in hundreds of feet of rocks that filled the impact site within the first day after the massive asteroid struck.

Researchers provide the most detailed look into the aftermath

The evidence is comprised of charcoal bits and rocks that were free of sulfur. They are part of a rock record that Sean Gulick, a research professor at the University of Texas Institute for Geophysics (UTIG) at the Jackson School of Geosciences, who led the study, called the most detailed look into the aftermath of the asteroid that put an end to the Age of Dinosaurs.

“It’s an expanded record of events that we were able to recover from within ground zero,” said Gulick in a press release announcing the study, which was published in Proceedings of the National Academy of Sciences. “It tells us about impact processes from an eyewitness location.”

The study was built on earlier research on how the crater was formed and how long it took for life to recover from the devastation. More than two dozen scientists located around the world contributed to the study. 

Rocks that filled up crater were free of sulfur 

The researchers found that most of the materials that filled up the crater after the asteroid hit were produced at the impact site or was pushed in by seawater that poured back into the crater from the Gulf of Mexico. Because so much material was deposited in the crater at a rapid rate, researchers were provided with clues about the lasting effects of the impact. It was described by Gulick as an inferno that didn’t last long followed by a longer period of cooling around the globe. “We fried them and then we froze them,” Gulick said. “Not all the dinosaurs died that day, but many dinosaurs did.”

So what was life like for dinosaurs when the asteroid made impact?

Researchers said the impact was equal to the power of 10 billion atomic bombs the size of the one used in World War II. Upon impact, fires broke out, with trees and plants thousands of miles away igniting. Meanwhile, a huge tsunami that reached as far as Illinois flooded the planet. What’s more, researchers said they found evidence that the burned landscape was also pulled into the crater when the tsunami receded. 

Real dinosaur killer atmospheric 

One of the biggest takeaways, according to researchers, is the fact that none of the rocks in the impact crater had any sulfur although rocks surrounding it did. That backs the theory that the asteroid vaporized the sulfur minerals at the impact site sending it into the atmosphere which reflected sunlight away and ushered in the cooling period.

“The real killer has got to be atmospheric,” Gulick said. “The only way you get a global mass extinction like this is an atmospheric effect.”

Human bodies keep moving for more than a year after death, researcher finds – Edmonton Sun

The finding could ‘significantly’ change how post-mortem investigations are carried out, especially in cases of unexplained deaths

The zombies from ‘Walking Dead’ may be frighteningly closer to reality than you’d like to imagine. 

Australian researchers have observed human bodies moving for more than a year after death, a finding that can greatly change how post-mortem investigations are conducted, they say. 

Researchers at the Australian Facility for Taphonomic Experimental Research (AFTER), informally known as a body farm, used a time-lapse camera to take overhead pictures of a corpse every 30 minutes during daylight hours for 17 months. 

“What we found was that the arms were significantly moving, so that arms that started off down beside the body ended up out to the side of the body,” medical scientist Alyson Wilson told ABC Australia.   

While the team expected some post-mortem movement in the early stages of decomposition, the length at which they observed the body moving was a surprising find. 

These findings could “significantly” impact unexplained death investigations she added. Previously, forensic scientists assumed that the position of a discovered body was the position at time of death — if there was no evidence proving that the body was moved. 

“We think the movements relate to the process of decomposition, as the body mummifies and the ligaments dry out,” she explained. 

Wilson could not immediately be reached for comment.

However, Shari Forbes, director of Canada’s first body farm — and former director of AFTER — said the finding isn’t all that uncommon. “It’s well-known to researchers but not conveyed to police investigators,” she said, namely due to the lack of facilities around the world, outside of the U.S.

The reasons for prolonged movement aren’t all that mystifying either, she added. It could be a number of things — insect larvae, shrinkage of body tissue, scavenging.

Wilson also found, over the course of three years, that corpses left outdoors would mummify — the process by which the skin and flesh of a corpse is preserved — under the right circumstances.

“We used to think it could only happen in a hot-and-dry environment or cold-and-dry — the key word being dry,” explained Forbes. However, the research reveals that natural mummification isn’t necessarily dependent on environmental factors and could be due to anything drawing moisture out from the body such as insects, dry soil, solar radiation.

It would differ around the world, added Forbes. For example, the process of mummification in Canada could result in two extreme scenarios — the body would freeze during winter leading to some degree of mummification or rapidly decompose during the warm summers.

Wilson’s research also confirmed the value of a time-lapse camera to study the decomposition rate of a human body in any environment. In a study published last month, she used the camera to test whether a scientific equation used to estimate a body’s decomposition in the northern hemisphere could apply to an Australian environment.

“Until we had AFTER, most of the science on how bodies decomposed was based on the northern hemisphere, where the climate is different, the weather is different and even the insects can be different,” she said.

This is the “first time” such photos have been recorded, according to Dr. Xanthe Mallett, a forensic anthropologist and criminologist at the University of Newcastle. 

“Previously, if the police had asked me if a set of human remains were found and they were mummified, I would have said it’s likely that that person was left outside in autumn and winter,” added Mallett. The new data “opens up the entire year for mummification in the correct circumstances, and it stops us from going down the wrong path.”

CINDY'S SNAPSHOT: A full Harvest Moon over Dominion, Cape Breton | The News – The News

At 1:33 ADT (2:03 NDT) Saturday a.m., the September moon became the Full Harvest Moon. Corinne Reid took this stunning photo just hours before that, as Earth’s only natural satellite came up over Dominion Cape Breton, N.S. The Harvest Moon is the full moon closest to the fall equinox; some years, the full moon in October gets the honours of being called the Harvest Moon.
