According to the British newspaper “Daily Mail”, the space rock that collided with Earth 66 million years ago left a global winter, destroying environments suitable for the largest animals ever roaming the earth.
Some experts claim that volcanic eruptions in a region in India known as “Deccan Traps” led to their extinction, but researchers demonstrated that this was not the case K and found that the asteroid impact off the coast of Mexico had destroyed all appropriate habitats but volcanic activity left areas around the equator.
The research team says that the lava emanating from the Deccan Traps volcanoes that lasted for thousands of years in fact helped life recover from the asteroid’s impact.
“The environmental impacts of the asteroid have destroyed the appropriate environments for dinosaurs,” said lead researcher Dr. Alessandro Chiarenza of Imperial College London. “On the other hand, the effects of severe volcanic eruptions were not strong enough to significantly disrupt global ecosystems.”
The researcher added: “Our study confirms, for the first time in quantitative terms, that the only reasonable explanation for the extinction is the influence of the winter that killed the dinosaur habitats around the world.”
The asteroid went out to break a crater 120 miles deep in the Yucatan Peninsula in the Gulf of Mexico, and within minutes, everything was burned hundreds of miles away.
Temperatures decreased, acid rain fell, and the sun was clouded for several months, causing the extinction of 90% of the plants and 70% of the animals.
The team combined the geological signs of climate and mathematical models with the precipitation and temperature that all kinds of dinosaurs needed to thrive, then they were able to draw a map where these conditions will remain in the world after either the asteroid strike or the huge volcano.
The team discovered it was the only damage from asteroid strike to all potential habitats, while volcanoes left some viable areas around the equator.
This volcanic warming has helped to enhance the survival and recovery of the animals and plants that caused the extinction as many groups expanded in their immediate aftermath, including birds and mammals.
