The study builds on previous research that explains how the crater was formed and validates the notion that the asteroid's impact caused the planet's surface to behave like a fluid, creating the mountains and hills that surround the crater from rocks that came from deep within the Earth's crust.
About 66 million years ago, the Cretaceous period ended with the extinction of three-quarters of animals and plants, including dinosaurs.
The new research showed scientists that the impact "created a big tidal wave that washed across this continent, and really changed the face of the planet in that location - or, really, changed the face of the planet overall entirely", Pitts said.
'Not all the dinosaurs died that day - but many dinosaurs did'.
The new research was based on rocks collected in 2016 from the Chicxulub impact site off the coast of the Yucatan Peninsula in Mexico.

In just one day, almost 130 metres of material built up inside the crater - a rate that's among the highest ever encountered in the geologic record.
The impact caused wildfires, tsunamis and put so much sulphur into the atmosphere that it blocked the sun. This rate of accumulation means that the rocks recorded what was happening in the environment within and around the crater in the minutes and hours after impact, and can also give us clues about the longer-lasting effects of the impact.
The impact then generated a tsunami several hundred meters high which reached as far as modern day IL in the US.
Inside the crater, researchers found charcoal and a chemical marker associated with soil fungi that shows signs of being deposited by resurging waters.
This showed experts that the burnt landscape was pulled into the crater with the waters of the tsunami.
The explosion from the impact instantly triggered various wildfires inland. The data suggests that on impact, the rocks flew out, creating a ring protrusion around the crater.

However, one of the most important takeaways from the research is what was missing from the core samples. But there was no sulfur in the core.
"That's about 10,000 times more than the amount of sulphur released during the 1883 eruption of Krakatoa, which cooled the Earth's climate by an average of 1.2°C for five years".
According to the researchers' calculations, somewhere around 325 billion metric tons of sulphur would have been ejected by the impact.
It was this global climate change that caused a mass extinction, killing off the dinosaurs along with most other life on the planet at the time.
Sean Gulick, lead author of the latest paper, said the wave would have been at least hundreds of meters high-and that it was traveling around the speed of a jet plane. The mass extinction event was the result of an impact event by an asteroid that created the 180 kilometre wide Chicxulub crater in Gulf of Mexico.More news: Cricket fraternity hails Australia on retaining Ashes urn
