Why Were Some of the Dinosaur Skeletons Radioactive?
During the late Cretaceous period, approximately 66 million years ago, a catastrophic event known as the Chicxulub impact occurred. This event involved the collision of a large asteroid or comet with the Earth, resulting in widespread destruction and the extinction of approximately 76% of all plant and animal species, including the dinosaurs.
However, recent research has discovered that some dinosaur skeletons from the aftermath of this impact exhibit elevated levels of radiation. Scientists believe that this radioactivity is due to the presence of uranium and thorium in the surrounding soil and groundwater. These elements were released into the environment as a result of the impact and were absorbed by the dinosaur bones over time.
This discovery has significant implications for understanding the ancient environment and the long-term effects of large-scale impact events. By studying the radioactive dinosaur skeletons, scientists can gain valuable insights into the composition of the Earth's crust and atmosphere millions of years ago.
