A New Timeline of the Day the Dinosaurs Began to Die Out

In the article, A New Timeline of the Day the Dinosaurs Began to Die Out, in the New York Times, scientists have found important evidence about the day a large asteroid hit Earth by digging into the peak ring of the Chicxulub crater. I started to read this article because I like to read about dinosaurs. The Chicxulub crater is beneath the Yucatan Peninsula and is one of the largest impact craters on Earth. It is 60 miles across and 20 miles deep. The scientists were able to find out what happened after the asteroid hit, which included raining rocks, tsunamis, wildfires, and rock that catapulted into the atmosphere. This new information they discovered is based on 430 foot long sedimentary rock found at the Chicxulub crater during drilling. It was discovered by using high resolution photography, microscopy, computed tomography imaging, and magnetic measurements. 

By drilling, scientists were able to find out more details about what happened to the dinosaurs on Earth when the Mesozoic Era ended. After the Mesozoic Era ended, the Cenozoic Era began. Because of the research, we understand better now how many of the dinosaurs died. Having better information about what happened that day could lead to more discoveries about life on Earth during the Mesozoic era. They could find information about animals we didn’t know existed during that time. I studied the Earth at school during science, and Earth scientists research the history of Earth so we can protect it in the future. We all live on this planet so it is important to know how to take care of it.
