Scientists Expose Cause Of Dinosaur Extinction Through Chicxulub Crater In Mexico

Dinosaurs ruled the Earth for 135 million years before their disappearance.

Scientists have many different hypotheses for its extinction. One of the possible explanations is the Asteriod Impact Hypothesis, which describe that an asteroid hit the earth. This set off forest fires around the globe, and caused catastrophic changes in the environment because of the dust thrown up into the air blocking out sunlight.

At this time, this hypothesis is the most popular rationalization of dinosaur mass extinction. There is a large crater at Chixulub in southern Mexico that could have been made an outcome of an asteroid hitting the earth.

The crater triggers the curiosity of scientists and lead to unearth the remains of an asteroid impact which ended the age of the dinosaurs more than 66 million years ago.

That geological feature will be probed by scientists who will drill nearly 5,000 feet beneath the seabed’s surface in an effort to unravel mysteries of the ancient world-changing event. This is a two-month-long effort, the core sample found will be the first ever obtained from the center of the crater.

The drilling is scheduled to start in the spring of 2016. This will collect rare specimens from the impact crater. To lay the expedition’s plan, researchers from different organizations and laboratories have initially met in Mexico.

Sean Gulick from the Austin Institute for Geophysics said, “The sediments that filled in the [crater] should have the record for organisms living on the sea floor and in the water that were there for the first recovery after the mass extinction event. The hope is we can watch life come back,” Jackson School of Geosciences published.

After the mining of the core, the samples will be sent immediately to Germany. It will be examined first by several research groups from different countries, including the United Kingdom, Mexico, and the United States. The remaining samples will be held in Texas’ A&M University core repository for future studies.

Gulick, in another event, said “[The Chicxulub crater] is the only impact crater linked to a mass extinction event – therefore, it is an incredible opportunity to study how life recovered after the mass extinction,” the Daily Texan Online reported.
