The world was almost destroyed by forest fires, tsunamis and huge sulfur clouds the day after the asteroid that hit the dinosaurs, according to research.
New rock samples in the underwater crater left behind by the impact have confirmed the theories of scientists about what happened that day, they say.
About 75 percent of all life on earth was swept away by the devastating impact that struck with the power of 10 billion nuclear bombs.
Discoveries of charcoal, chunks of rock and sulfur-rich rocks in the seabed in the Yucatan area of Mexico have provided more detail than ever before.

Researchers from the University of Texas have been drilling nearly a mile into the earth to refine the timeline of what happened around 66 million years ago.
& # 39; It is a comprehensive report of events that we were able to correct from ground zero & # 39 ;, said Professor Sean Gulick, the project leader.
& # 39; They are all part of a rock record that offers the most detailed look in the aftermath of the catastrophe that ended the dinosaur era. & # 39;
Professor Gulick and Professor Joanna Morgan, of Imperial College London, collected cores from 1365 meters (1,300 m) below the sunken & # 39; Chicxulub & # 39; crater.
It is located 24 miles from the port of the Yucatan Peninsula in Mexico, it is more than 185 miles (185 km) wide and 20 miles (32 km) deep. Half are under water and the rest covered by rainforest.
Researchers from the University of Texas sampled earth in the crater where the asteroid hit 66 million years ago in what is now Mexico, and found granite, sandstone and limestone rocks as well as charcoal
The team carried out their work aboard a boat that was converted into a 40-foot (12 m) high drilling station that stood on three pillar-like legs.
While they dug into the crust, they pulled up cylindrical monsters.
What they found were rock monsters who, because they were forced into the ground so quickly, could point it out a breakdown of events per minute.
They found molten and broken rocks, including sandstone, limestone and granite.
The ill-fated asteroid is believed to be between 6.2 miles and 9.3 km wide (10-15 km) and hits the earth at a speed of about 44,000 miles per hour (70,000 km / h).
According to Professor Gulick's team, the earth-shattering impact caused widespread hell.
It set fire to trees thousands of miles away and caused a giant 91-meter tsunami that drove as far inland as the American state of Illinois is currently located.
Tsunami seawater swept debris into the crater at such a speed that the first day deposited about 425 feet (130 m) of natural wreck.
So much sulfur was thrown into the atmosphere that it blocked the light from the sun.
Although none of the chemicals could be found in the drilled samples, there are sulfur-rich rocks in the crater.
This fits in with the theory that most of these rocks had evaporated when the asteroid struck, sending around 325 billion tons of gas into the air, blocking the sun and lowering the temperature.

It is believed that the asteroid that swept away the dinosaurs is (illustrated) between six and 10 miles wide (10-15 km) and travels at a speed of about 44,000 miles per hour (70,000 km / h)
& # 39; We baked them and then we frozen them & # 39 ;, said Professor Gulick. & # 39; Not all dinosaurs died that day, but many dinosaurs died. & # 39;
Some dinosaurs were burned or drowned alive, but most shivered and died of hunger, the team said.
While the collision explosion and the fires and huge waves killed living things in their local environment, it was this gas cloud that caused extinction worldwide.
Professor Gulick added: & # 39; The real killer must be atmospheric. The only way to achieve global extinction in this way is an atmospheric effect. & # 39;
The team's research was published in the journal Proceedings of the National Academy of Sciences (PNAS).
WHY ARE THE DINOSAUR HOURS EXCLUDED?
Dinosaurs ruled and dominated the earth about 66 million years ago, before they suddenly died out.
The Cretaceous Tertiary Extinction event is the name given to this massive extinction.
It has been believed for many years that the changing climate destroyed the food chain of the huge reptiles.
Paleontologists discovered a low iridium in the 1980s.
This is an element that is rare on earth but is found in large quantities in space.
When this was dated, it exactly coincided with when the dinosaurs disappeared from the fossil record.
Ten years later, scientists discovered the huge Chicxulub crater at the tip of the Yucatán peninsula in Mexico, dating back to the relevant period.
Scientific consensus now says that these two factors are interconnected and both were probably caused by a huge asteroid that crashed on Earth.
With the projected size and collision speed, the collision would have caused a huge shock wave and probably caused seismic activity.
The fall would have created ash plumes that probably covered the entire planet and made it impossible for dinosaurs to survive.
Other animals and plant species had a shorter time span between generations that allowed them to survive.
There are several other theories about what caused the death of the famous animals.
An early theory was that small mammals ate dinosaur eggs and another states that poisonous angiosperms (flowering plants) killed them.
