Scientists have unearthed of how the dinosaurs died out 65 million years . Geophysicists are analyzing rock in a crater under the off Mexico. The rocks were created from the cataclysmic of a gigantic asteroid hitting Earth. Scientists say the rock reveal a step-by-step account of the destruction that happened after the impact. Rocks and sediment settled on top of each in revealing layers. A geophysicist said: "It tells us what went on the crater on that day of that killed the dinosaurs. All of mayhem is recorded in the core."

Scientists say the asteroid was up to four kilometers . It smashed into the ocean and created a 160kms wide and 20kms deep. This started a reaction of earthquakes, tsunami, landslides and that forever changed the of Earth. It also killed off the dinosaurs. The asteroid's impact hurled out and created a huge crater. Molten rock fell back into the crater, which was then filled with water. This water was full of soil, vegetation, life and other debris. It took a few to settle in layers for scientists to analyze millions of years later.
